# PUBLIC COMMENT ON PROPOSED REGULATIONS: Airworthiness Directives; The Boeing Company Airplanes

**Submitted by the Center for Federal Accountability (CFA)**  
**Document Number:** 2026-02420

## Executive Summary

The Center for Federal Accountability submits this draft comment to support timely public record participation while full model-backed legal analysis is queued. This draft identifies baseline accountability concerns and preserves key issues for agency consideration before the close of comments.

## Table of Authorities (to be finalized)

- Administrative Procedure Act (5 U.S.C. 551 et seq.)
- Agency enabling statute and implementing regulations (rule-specific citations to be finalized)

## Key Concerns

- The agency should clearly identify statutory authority for each material requirement in the proposal.
- The agency should provide transparent cost, burden, and implementation assumptions with reproducible methodology.
- The agency should address foreseeable operational risks and unintended consequences for regulated parties and the public.

## Preliminary Analysis

This preliminary draft is generated from the available Federal Register text excerpt below and is intended to preserve issues for the rulemaking record. A full model-backed CFA legal analysis can be substituted in a subsequent revision.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all The Boeing Company Model 777-200, -200LR, -300, and -300ER 
series airplanes. This proposed AD was prompted by a report of 
corrosion found on a satellite communications (SATCOM) high gain 
antenna adapter plate. This proposed AD would require repetitive 
inspections for corrosion of the SATCOM high gain antenna adapter plate 
and applicable on-condition actions. The FAA is proposing this AD to 
address the unsafe condition on these products.

DATES: The FAA must receive comments on this proposed AD by March 23, 
2026.

11.43 and 11.45, by any of the following methods:

## CFA Recommendations

1. Publish a clear crosswalk from each proposed requirement to its statutory basis.
2. Expand and disclose the quantitative assumptions used in cost-benefit analysis.
3. Provide implementation alternatives and phase-in options to reduce compliance risk.
4. Extend or reopen comment if substantial updates are made after publication.
