EASA AD US-2018-22-04
Flight Controls - Trailing Edge Flap Rotary Actuator - Inspection / Replacement
Airworthiness Directive 2018-22-04 is a final rule issued by the Federal Aviation Administration addressing certain Boeing Model 787-8 and 787-9 airplanes. It mandates inspection and potential replacement of inboard and outboard trailing edge flap rotary actuators due to incorrect assembly of the no-back brake rotor-stator stack sequence. This AD aims to prevent reduced braking performance and loss of no-back brake function that could affect airplane controllability.
