Forecast: Probability distribution:
We need the count of FAA final Airworthiness Directives (ADs) published in the Federal Register that are specifically applicable to Boeing aircraft models, with publication dates from 2026-06-01 through 2026-07-31 (61 days).
The main disagreement is about the baseline rate. Forecaster 1’s distribution (median ~19, substantial mass above 25) appears to rely on an assumed Boeing AD cadence of ~8–15/month and ~100–150/year; that is hard to reconcile with the other analysts’ direct Federal Register sampling and would imply an unusually high sustained issuance rate for Boeing-specific final ADs.
Forecasters 2–4 anchor to observed 2025–mid-2026 Federal Register patterns, with Forecaster 4 giving the most explicit recent baseline: about 16 Boeing final ADs across Jan–May 2026 (~3.2/month), implying ~6–7 over two months. Forecaster 2 is similar (median ~8), while Forecaster 3 is lower (median ~4) but based on a thinner sample (noting a proposed rule on public inspection that wouldn’t count).
Given (a) the more concrete recent run-rate evidence clustering around ~2–4/month, (b) modest overdispersion (ADs can cluster), and (c) no strong reason to expect an extreme surge specifically in June–July 2026, I center the distribution around 6–7, with a fairly wide upper tail for an unusual burst of ADs, but with very little probability of exceeding the open upper bound (25.5).
An amateur forecast is likely to (i) accidentally include proposed ADs or non-Boeing-targeted ADs, (ii) anchor on Boeing’s high-profile safety scrutiny and overinflate the count, or (iii) anchor on early-June “so far” observations and understate the remainder of the window.
This forecast improves by weighting the analysts’ most defensible evidence (recent Federal Register-based run rates for Boeing final ADs) and explicitly discounting the outlier high-cadence assumption, while still keeping a realistic overdispersed upper tail for clustered publications. Confidence is moderate: the main uncertainty is a potential one-off spike from an emerging fleet-wide issue or administrative backlog clearance.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the main reasoning pattern is a blend of recent publication pace and longer-run FAA base rates, with explicit adjustment for the 57-day window from June 1 to July 31, 2026.
Overall, the forecasts suggest a modest-to-moderate number of Boeing Airworthiness Directives in the two-month period, with expected counts driven by a combination of recent trend, historical FAA norms, and the possibility of sporadic safety-driven bursts. The distribution is best understood as right-skewed and highly uncertain, with the main debate centered on whether recent slower issuance should outweigh broader historical and regulatory pressures.
— Iteration 2 — Overall, the reasoning converges on a modest two-month total in the low single digits to mid-single digits, with most of the weight centered around roughly 4–6 Boeing-related ADs. The main factors driving the forecasts are:
In short, the collective reasoning points to a moderate but uncertain count, anchored by recent slow activity, tempered by historical norms, and shaped by the possibility of batched FAA publications.
— Iteration 3 — Across the forecasts, the main driver is historical FAA publication cadence for Boeing-related final Airworthiness Directives. The models generally assume the Federal Register will continue issuing Boeing ADs at a fairly regular but bursty/lumpy pace, which makes a simple linear extrapolation imperfect. Most of the reasoning scales a two-month window from a rough historical annual rate, implying a result in the mid-single digits to low double digits.
A second shared point is that the early-June silence is not very informative by itself. The fact that no final Boeing ADs were documented in the first few days of the window slightly lowers expectations in one estimate, but the others treat that as too short a period to matter much. All of the rationales also distinguish final ADs from proposed rules or non-final actions, which do not count for this question.
There is broad agreement that the distribution should be wide-tailed, reflecting regulatory batch publishing and the possibility of either:
The main disagreement is on the central estimate: one forecast is more conservative, centering around 3, while the others place the middle of the distribution around 6 to 10. Overall, the collective reasoning points to a moderate total, likely around 6–8 final Boeing ADs, with substantial uncertainty around that center.

The research found that recent, relevant events include the November 2025 UPS MD‑11 crash in Louisville (engine separation) and a June 4, 2026 Lufthansa Boeing 787‑9 nose landing gear collapse; investigators noted Boeing had documented related failures previously while the FAA did not always issue mandatory ADs in past cases. The FAA published a Notice of Proposed Rulemaking on April 27, 2026 for Boeing 737 fuselage skin cracks (a proposed AD that could become final within the window) and there are recent Boeing AD examples (e.g., AD 2025‑25‑04, effective January 16, 2026). The FAA Dynamic Regulatory System shows a total of 17,047 AD final rules/emergency ADs across manufacturers as of May 31, 2026. Searches did not locate any active prediction‑market markets specifically forecasting the number of Boeing ADs for June–July 2026, nor did the research turn up aggregate historical statistics giving a clear monthly or two‑month base rate for Boeing AD publications; the research therefore notes an absence of readily available historical monthly counts and of prediction‑market liquidity/volume for this exact question.

Modal: 3-6 (36.0%) • partial_shift • 6m54s
Reading: strict
The resolution criteria are precisely specified: only final ADs (not proposed), only those with Federal Register publication dates strictly within June 1–July 31, 2026, and only where Boeing is the subject/applicability entity. This narrow, literal definition leaves little room for charitable expansion and the fine print further restricts counting (once per AD, FAA-issued only).

Evidence confidence: low
medium evidence]Historical monthly rate of ~2–3 Boeing ADs implies 4–6 total for two months. If FAA pipeline slows due to summer regulatory scheduling, staffing, or fewer critical Boeing safety issues maturing to final rule status in this window, the count could fall at the low end of the historical range or below it.
Heightened Boeing regulatory scrutiny in recent years has tended to increase AD issuance rates. Two months is a meaningful window and even a slow month would likely yield some final ADs. The observed NPRM (source 5) suggests at least some Boeing ADs are in the pipeline.
medium evidence]If the FAA’s issuance rate is closer to 3–6 Boeing ADs per month (reflecting elevated scrutiny of Boeing following recent safety incidents), a two-month window could yield 7–12. This is also consistent with the answer range ceiling of ~25, suggesting the question designers anticipated meaningful counts above the low base rate.
The observed monthly rate from source 2 does not clearly support rates as high as 4–6 per month — most identified months show 2–3 Boeing ADs. The answer range extends to 25.5, but the question designer’s range choice does not itself constrain the most likely outcome.
low evidence]If the FAA has a large backlog of Boeing ADs moving from NPRM to final rule stage, or if a safety event triggers emergency or accelerated AD issuance, monthly counts could spike well above historical averages. The answer range ceiling near 25 acknowledges this possibility.
No direct evidence supports sustained rates this high. The historical monthly observations from early 2026 are 2–3 per month, making 13+ over two months a major upward departure. Emergency or accelerated ADs are rare and usually tied to specific triggering events not currently documented in the evidence.
low evidence]If the FAA’s pipeline for Boeing ADs is temporarily depleted (e.g., most pending ADs are still in NPRM phase as seen with source 5), or if the agency shifts resources, the June–July final rule count could be unusually low.
Historical patterns consistently show at least some Boeing final ADs each month. A complete drought over two months would be historically unusual given the ongoing Boeing safety regulatory environment.
inside_view_v1)Inside View — Causal Mechanism Analysis
Current state → causal chain:
The evidence shows approximately 8–14 Boeing final ADs published in the Federal Register across ~5 months (Jan–May 2026), per sources 1 and 2. This gives a rate of ~1.6–2.8 Boeing final ADs per month. The two-month window (June 1–July 31) spans ~61 days.
Base rate projection:
- Low estimate: 1.6/month × 2 = ~3.2
- High estimate: 2.8/month × 2 = ~5.6
- Central implied range: ~3–6 Boeing final ADs
Scenario weighting by evidence strength:
Low-end count (1–6):
relative_evidence_strength: medium— The 2026 monthly rate of ~2–3/month directly supports this. Most likely central outcome based on observed rates.Mid-range count (7–12):
relative_evidence_strength: medium— Source 1 shows January 2026 had at least 5 Boeing ADs alone, suggesting higher-variance months are possible. If FAA is accelerating oversight post-2023-2024 Boeing safety incidents, June–July could see elevated rates.High-end count (13–25):
relative_evidence_strength: low— No direct evidence supports this; would require emergency/backlog surge far above observed rates.Very low count (0–3):
relative_evidence_strength: low— June 8 NPRM (source 5) for 747-8 won’t finalize in-window; historically unusual for 2 months to produce fewer than 3 final ADs.Confidence in evidence is “low” per the brief, meaning I need to widen the distribution.
Distribution reasoning:
- The ~2–3/month base rate is the strongest signal (medium-evidence scenarios)
- For a 2-month window, I expect ~4–6 as the modal outcome (bin_1: 3-6 and bin_2: 6-9)
- January’s spike to 5+ in one month creates real probability of 7–12 range (bin_3: 9-13 gets some mass)
- Low evidence scenarios (very high or very low) get smaller but non-trivial mass given “low” confidence in evidence
- The NPRM pipeline (source 5) suggests ADs will materialize, reducing probability of the 0-3 bin
- Elevated Boeing scrutiny provides upside pressure on rates
Distribution:
- 0-3 (bin_0): ~10% — historically unlikely for 2 months; pipeline is active
- 3-6 (bin_1): ~32% — central mass around the 2-3/month base rate extrapolated to 2 months
- 6-9 (bin_2): ~28% — January’s higher rate and ongoing scrutiny make this plausible
- 9-13 (bin_3): ~15% — possible if pipeline accelerates or monthly rate is higher than observed
- 13-16 (bin_4): ~7% — low-evidence scenario; would need significant acceleration
- 16-19 (bin_5): ~4% — low probability
- 19-22 (bin_6): ~2% — very low probability
- 22-25 (bin_7): ~1% — very low probability
25 (bin_8): ~1% — very unlikely
outside_view_v1)Reference class: two-month counts of FAA final Airworthiness Directives (ADs) that apply to Boeing aircraft, based on early-2026 issuance rates. Base rate: roughly 2–3 Boeing final ADs per month observed through May 2026 → ~4–6 ADs over a two‑month window (Research Brief evidence_summary; key_facts items 3–4). Adjustment: I keep the outside‑view anchored to that base rate but widen the distribution because (a) evidence quality is low (Research Brief: confidence_in_evidence = low) and (b) the pipeline status is ambiguous — as of June 5 there are zero confirmed Boeing final ADs in the window yet there are NPRMs (e.g., June 8 NPRM 2026-11472) that could become finals (Research Brief key_facts 2 and 7). Final: I place most mass on 3–6 ADs (bin_1) at 56%, reflecting the base‑rate center; assign 20% to 0–3 (bin_0) because the monotone floor is currently zero and some NPRMs may not finalize in this window; assign 12% to 6–9 (bin_2) and 7% to 9–13 (bin_3) to reflect the medium‑evidence mid‑range scenario (Research Brief scenarios tagged medium). Small tail mass (3% bin_4, 1% bin_5, 0.5% bin_6, 0.5% bin_7) captures the low‑evidence possibility of a spike (backlog, emergency ADs) noted in the brief but not well supported. Weighting note: per the brief’s scenario tags, I concentrated probability on the medium‑strength scenarios (low‑end and mid‑range) rather than treating all scenarios equally; the low‑ and high‑end scenarios with only low supporting evidence receive correspondingly smaller tail weight. Reading: strict — counts only final ADs published in the Federal Register between 2026-06-01 and 2026-07-31 where applicability includes Boeing (per resolution criteria and Research Brief classifier_rationale). Overall confidence in this forecast is modest given the brief’s low evidence quality; that uncertainty is reflected by the relatively wide tails around the base‑rate bin.
contrarian_v2)Adversarial reading
The implicit consensus from the brief is a low-to-mid count (roughly 4–12 final Boeing ADs) driven by the observed ~1.6–2.8 per month rate through May 2026, tempered by the possibility of elevated scrutiny pushing the rate modestly higher. The two medium-strength scenarios (low-end 1–6 and mid-range 7–12) dominate the evidence weighting.
Counter-evidence found (or absence)
Searched for counter-evidence; nothing substantive found; consensus appears robust. The high-end (13–25) and very-low (0–3) scenarios are both tagged low evidence strength, and the brief explicitly notes that the observed sequence data and NPRM pipeline do not support sustained departures from the 2–3/month historical pattern.
Distribution implications
Because the medium-strength scenarios cluster in the 1–12 range and the high-end scenario receives only low weight, the distribution places materially more mass on bins 1–3 (3–13) than a naive uniform spread would imply, while still allowing modest probability on the tails to reflect the acknowledged uncertainty around emergency/accelerated ADs and the exact 2026 monthly rate. Bin 0 receives non-negligible but minority mass because a complete drought would contradict the steady pre-window issuance documented in sources 2 and 4.
Strategy: logit_mean • Drafts: 3/3
anchoring_v1The draft rationale anchors the p50 at the front of the plausible range by taking 2–3 Boeing ADs/month as the base rate and projecting ~4–6 for two months, placing ~40% of mass in 3–6 (bin_1). However, this rate estimate comes from a small, imprecisely counted sample: only 8 sequence-number data points identified across 5 months, using a cross-manufacturer numbering system that makes Boeing-specific counts unreliable. The brief itself acknowledges “approximately 8–14 Boeing final ADs” across 5 months — the midpoint of that range is ~11, implying ~2.2/month, but the upper end (14 ADs, ~2.8/month) over 2 months yields ~5.6, sitting near the bin_1/bin_2 boundary. More critically, the brief notes January 2026 had “at least 5 Boeing ADs” in a single month, yet the forecast treats this as a single upside data point rather than evidence the true monthly rate distribution has a higher mean than the 2–3 low-end implied rate. The draft places only ~22% mass in 6–9 (bin_2) and ~14% in 9–13 (bin_3), despite the medium-strength mid-range scenario (7–12) receiving equal evidence strength to the low-end scenario. A flat-prior interpretation of two equally-weighted medium-strength scenarios would distribute mass more evenly between bin_1 and bins 2–3, rather than loading ~40% into bin_1 alone.
ceiling_v1The structural constraint I focus on is the hard upper ceiling implied by the observed base rate plus the two-month window duration. The evidence states “approximately 8–14 Boeing final ADs were published in the Federal Register across roughly 5 months (January–May 2026), implying a rate of ~1.6–2.8 per month.” Over exactly two months (June 1–July 31), this gives a structural ceiling of roughly 5.6 ADs at the high end of the observed rate — even generously extending to 3×/month for elevated scrutiny gives only ~6. For the distribution to place ~19% of mass above above 9 ADs (bin_2), it requires a sustained monthly rate of 4.5+/month, which is approximately 60–180% above the observed ceiling of 2.8/month. The brief itself tags the 7–12 and 13–25 scenarios as requiring “major upward departure” from historical rates, yet the draft assigns roughly 30% combined mass to bins above 6. No structural precondition (documented emergency AD triggers, confirmed regulatory surge, large NPRM-to-final pipeline) has been established that would justify that much mass above ~9.
math_v1The forecast shows a coherent internal structure with bin mass concentrated on the lower-to-middle outcome range (bins 1–3: 3–13 ADs), consistent with the 2–3 per month base rate observed in the evidence and the estimated 2-month window yielding ~4–6 ADs. However, there is a critical distribution-label mismatch: the draft presents a dictionary with string keys (“0-3”, “3-6”, etc.) but the submission schema requires integer keys (bin_0, bin_1, bin_2, …, bin_8). More importantly, summing the probabilities yields 0.978 when the schema requires a sum of 1.0 ± 0.01. The missing 0.022 mass is unaccounted for, violating the normalization constraint.
Reviews consumed: 3
The draft already sits near consensus (median ~5.6 ADs). The anchoring reviewer flagged that I’m under-weighting the equal-strength mid-range scenario (7–12) and that January’s 5+ ADs in one month suggests the true rate may be higher; I partially accepted this by shifting modest mass from bin_1 toward bin_2 and bin_3. The ceiling reviewer flagged that 2.8/month × 2 months caps near ~5.6 and that upper-tail mass above 9 lacks structural justification; I partially accepted by trimming the far-upper tails (bins 5–8) but kept moderate mass on bin_2/bin_3 because the anchoring reviewer and the January spike data point the other way. These two reviewers pull in opposite directions, so I landed between them — slightly higher than the ceiling reviewer’s distribution, slightly lower than the anchoring reviewer’s. The math reviewer flagged a normalization/key-format issue in the draft (sum=0.978, string keys); I fixed both by using bin_id keys and ensuring sum=1.0. Final distribution peaks at 3–6 (bin_1) with substantial mass on 6–9 (bin_2), tapering to thin tails.
[ceiling] Mass in bins 6–8 (>19 ADs) is overweighted given no structural mechanism for rates 7–10× baseline.
[anchoring] January 2026 had 5+ Boeing ADs in one month, suggesting the true monthly rate distribution has a higher mean than the 2–3/month low-end estimate.

Model’s Answer: Looking at this question, I need to forecast the number of final Boeing Airworthiness Directives (ADs) published in the Federal Register between June 1 and July 31, 2026.
Key Information Analysis:
From the social media research, I can see several recent Boeing ADs:
Critically, the research notes: “As of June 5, 2026, one notable Boeing AD was published in late May 2026 (747-related), with effectiveness extending into July. No final Boeing ADs appear in the first few days of June 2026 based on available records.”
The research also states: “Past two-month periods have typically seen 0–4 such final ADs.”
Historical Baseline: The pattern from early 2026 shows approximately 1-2 Boeing ADs per month, suggesting a baseline of 2-4 for a two-month period. However, the heightened regulatory scrutiny of Boeing post-MAX incidents and ongoing quality concerns suggest the rate may be elevated.
Key Assumptions and Their Risks:
Low Outcome Scenario (1-2 ADs): Few pending issues resolve to final rule status; FAA resource constraints delay publications; no new significant safety concerns emerge. Probability: ~10%
High Outcome Scenario (10+ ADs): A major safety finding affects multiple Boeing models; cluster of pending NPRMs all finalize simultaneously; or emergency directive situation similar to MAX groundings. Probability: ~10%
Central Reasoning: Given the historical baseline of 0-4 ADs per two months, but accounting for:
I estimate a median around 4-5 ADs, with reasonable uncertainty given the regulatory nature of these publications.
Percentile .1: 1 Percentile 1: 1 Percentile 5: 2 Percentile 10: 2 Percentile 15: 3 Percentile 20: 3 Percentile 25: 3 Percentile 30: 4 Percentile 35: 4 Percentile 40: 4 Percentile 45: 5 Percentile 46: 5 Percentile 47: 5 Percentile 48: 5 Percentile 49: 5 Percentile 50: 5 Percentile 51: 5 Percentile 52: 5 Percentile 53: 6 Percentile 54: 6 Percentile 55: 6 Percentile 60: 6 Percentile 65: 7 Percentile 70: 7 Percentile 75: 7 Percentile 80: 8 Percentile 85: 9 Percentile 90: 10 Percentile 95: 12 Percentile 99: 15 Percentile 99.9: 20
Rule issuance is governed by statutory timelines, legal review, and a publishing cadence that changes slowly.
Administrative capacity and maintenance cycles impose an inertial limit on how many final directives can clear review in any two-month window.
Year-to-date issuance has run below the long-term mean, producing a moderate expectation for the June–July interval.
An active docket of recent proposals raises the chance of mid-range finalizations, while a quiet first week in June reduces near-term momentum.
Batch publication or simultaneous clearance of multiple dockets would push counts into the upper tail.
Absent docket clustering, processing is likely to follow the lower recent regime and yield a modest count.
Classification ambiguity—whether engine-focused rules, correction-only notices, or mixed-manufacturer applicability count—creates sensitivity of a couple of items.
Operational shocks, expedited emergency directives, or unusual batching are low-probability pivots that nonetheless produce a meaningful upper-tail risk.
Forecast (median): 7.2318 Airworthiness Directives
How many Airworthiness Directives will the Federal Register publish for Boeing aircraft between June 1 and July 31, 2026?
Key figures
Historical context
Tailwinds
Headwinds
Detailed reasoning
My analysis focuses on the empirical publication rate of final Airworthiness Directives (ADs) for Boeing aircraft in the Federal Register leading up to the forecast window. Data from April and May 2026 shows a clustered but moderate issuance pattern. Specifically, three Boeing-related final ADs were published in late April (covering 757 models and others), and one final AD was published on May 29 (targeting 747 series airplanes). This establishes a recent baseline of approximately 3 to 4 documents every six weeks.
As of June 5, 2026, the Federal Register has recorded zero final Boeing ADs for the first five days of the tracking period. While this indicates a slow start, the typical FAA administrative cycle often results in clustered publications rather than a steady daily stream. A critical ‘pipeline’ item is the proposed AD regarding Boeing 737 Next Generation (NG) fuselage skin cracks. With the public comment period for this proposal closing on June 11, 2026, it is plausible—though not certain—that a final rule could be published before the July 31 deadline.
I have weighted the forecast toward a baseline ‘normal’ regulatory environment. This scenario (60% weight) assumes the FAA maintains its recent pace, resulting in 2 to 4 directives over the two-month span. I also considered an ‘elevated’ scenario (25% weight) where the 737 NG rule is finalized quickly alongside other backlog items, pushing the count toward 6 or 7. A smaller ‘quiet’ scenario (15% weight) accounts for potential bureaucratic delays that could push finalizations into August.
I specifically discounted several ongoing technical issues—such as the 777X engine durability concerns and the June 4 787 nose gear collapse in Frankfurt—as likely drivers of final ADs within this specific window. While these events trigger investigations, the administrative process from incident/discovery to a ‘Final Rule’ published in the Federal Register typically exceeds the 61-day duration of this forecast. Most certification milestones mentioned in earnings calls (like the 737 MAX 7/10) relate to new aircraft and do not automatically generate ADs for the existing in-service fleet. Therefore, the forecast remains anchored to the observed historical cadence of routine maintenance and safety corrections.
