View on Federal Register

Summary

The FAA is superseding Airworthiness Directive (AD) 2024-15- 03, which applied to all The Boeing Company Model 777 airplanes. AD 2024-15-03 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats and applicable on-condition actions for affected seats. AD 2024-15-03 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) for the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2024-15-03, the FAA determined that AD 2024-15-03 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2024-15-03 and revises paragraph (j) of this AD to clarify which actions are not required. The FAA is issuing this AD to address the unsafe condition on these products.

Market Impacts

  • The AD imposes new compliance requirements for Boeing 777 series airplanes, specifically targeting the Captain's and First Officer's seats to address uncommanded fore/aft movement. This could restrict market access for operators not complying with the new requirements.; The AD creates opportunities for maintenance providers and parts suppliers specializing in Boeing 777 series airplanes, particularly those offering compliant seats and related services.; New entrants or operators looking to expand their fleet with Boeing 777 series airplanes may face additional barriers due to the need to ensure all seats comply with the new AD requirements.

BOEING CO

Boeing is the direct manufacturer of the affected Boeing 777 series airplanes specified in the Airworthiness Directive, making this rule specifically targeted at their commercial airplane production operations. The company's Commercial Airplanes segment is directly responsible for manufacturing and compliance with FAA regulations for these aircraft models. The airworthiness directive specifically targets Boeing 777 aircraft seat safety compliance, which does not align with any of the company's disclosed risk factors focused on financial, pension, and supplier dependency issues. The company's single regulatory compliance risk relates to ERISA pension funding requirements, not aviation safety regulations, showing minimal relevance to this FAA rule.
