The Federal Aviation Administration (FAA) issued a new Airworthiness Directive (AD) for all Boeing 777 aircraft Tuesday morning to correct a gust suppression sensor problem. The move comes a week after the agency issued another directive to fix another problem on the same model.
According to the US aeronautical agency, the Airworthiness Directive was motivated by the high electrical resistance identified within the sensor of the burst suppression system due to corrosion of the sensor.
The airlines operating the Triple Seven must deactivate the gust suppression function within three months or before reaching 75,000 flight hours, the Federal Aviation Administration said through the document. The Airworthiness Directive, which took effect immediately, also requires aircraft operators to disconnect connectors, cap and store cables connected to modules affected by sensor corrosion.
The measure affects 279 aircraft of all model variants (-200, 200ER, 200F, 200LR, 300, 300ER and -300ERF) registered in the United States and operated by companies such as American Airlines and United Airlines, in addition to several other airlines. cargo, such as FedEx Express. As the system is not essential and does not affect safety as long as the measures adopted by the Federal Aviation Administration are strictly followed, there are no major implications and the airlines will continue to be able to fly the aircraft without any problem.
