Summary

The FAA is superseding Airworthiness Directive (AD) 2025-01- 06, which applied to all The Boeing Company Model 767-200, -300, -300F, and -400ER series airplanes. AD 2025-01-06 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 2025-01-06 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2025-01-06, the FAA determined that AD 2025-01-06 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2025-01-06 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.

The requirements include inspections, checks, and potential on-condition actions to address unsafe conditions related to the Captain's and First Officer's seats.; The AD creates opportunities for maintenance, repair, and overhaul (MRO) providers specializing in Boeing 767 series aircraft, as operators seek external support to comply with the new requirements.; The AD may act as a barrier to the resale or leasing of affected Boeing 767 models, as potential buyers or lessees will require assurance of compliance with the AD's requirements.

BOEING CO

Boeing is the direct manufacturer of the affected Boeing 767-200, -300, -300F, and -400ER series airplanes specified in the airworthiness directive. As the original equipment manufacturer, Boeing has direct responsibility for compliance with FAA airworthiness directives affecting its aircraft models, including required inspections, modifications, and service bulletins. The airworthiness directive addresses specific aircraft safety compliance requirements for Boeing 767 models, which does not align with any of the company's disclosed risk factors focused on pension underfunding, debt covenants, supplier dependence, ERISA obligations, and purchase commitments. The company's single regulatory compliance risk relates to pension funding (ERISA), not aviation safety regulations, showing minimal relevance.
