Airworthiness Directives; The Boeing Company Airplanes Federal Register ↗

Abstract

The FAA proposes to supersede Airworthiness Directive (AD) 2022-15-06, which applies to all The Boeing Company Model 777-200, - 200LR, -300, -300ER, and 777F series airplanes. AD 2022-15-06 requires disconnecting certain connectors and capping and stowing the wires that had been attached to the affected transorb modules. Since the FAA issued AD 2022-15-06, the agency has determined additional connectors are affected. Also, a replacement has been developed to address the unsafe condition, which would terminate the existing actions. This proposed AD would continue to require the actions specified in AD 2022- 15-06 and would require those actions for additional connectors. This proposed AD would also require determining if affected transorb modules are installed, replacing or testing affected transorb modules, and applicable on-condition actions. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
