Airworthiness Directives; The Boeing Company Airplanes

요약

The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This proposed AD was prompted by reports that the low range radio altimeter (LRRA) system has an increased rate of non-computed data (NCD) outputs at low altitudes during approach and landing, which could cause unreliable altimeter function. This proposed AD would require replacing the left and right LRRA transmit and receive coaxial cables with larger gauge coaxial cables. The FAA is proposing this AD to address the unsafe condition on these products.
