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.

Ice and Rain Protection - Cabin Air Compressor Inlet Ice Protection System Wiring - Modification

The Federal Aviation Administration's Airworthiness Directive 2018-17-03 addresses certain Boeing Model 787-8 and 787-9 airplanes. This directive focuses on the cabin air compressor inlet ice protection system wiring, specifically targeting failures in the lip heater assemblies caused by wire chafing. The AD mandates modifications to electrical connectors, wire routing, and installation of new or modified inlet duct assemblies to ensure continued airworthiness.

Air Conditioning - Software and Hardware - Installation

Airworthiness Directive 2018-12-06 is a final rule issued by the Federal Aviation Administration (FAA) addressing certain Boeing Model 787-8 and 787-9 airplanes. It targets an air conditioning system issue involving latent flow sensor failures combined with single cabin air compressor (CAC) operation that can cause CAC inlet overheating and damage. The directive mandates software and hardware updates to the cabin air conditioning and temperature control system to mitigate this unsafe condition.

AFM Change - Operational Limitations

Federal Register Volume 83, Number 81 (April 26, 2018) Final Rule Airworthiness Directive 2018-09-05 addresses Boeing 787-8 and 787-9 airplanes powered by Rolls-Royce Trent 1000-A2, AE2, C2, CE2, D2, E2, G2, H2, J2, K2, and L2 turbofan engines. This directive mandates revising the airplane flight manual (AFM) to impose limitations on extended operations (ETOPS) to reduce the risk of intermediate pressure compressor blade failures during high thrust settings after an engine failure. The AD aims to enhance flight safety by preventing potential dual engine failures during ETOPS diversions.

CANCELLED AND REPLACED BY FAA AD 2018-09-05

FAA Airworthiness Directive 2018-08-03 is a final rule addressing Boeing 787-8 and 787-9 airplanes powered by Rolls-Royce Trent 1000 Package C turbofan engines. It requires revising the airplane flight manual to limit extended operations (ETOPS) due to a risk of engine failure from prolonged high thrust operation on the remaining engine after an engine failure. This directive aims to prevent unrecoverable thrust loss that could lead to forced landings.
