SUPERSEDED BY FAA AD 2025-02-07
FAA Airworthiness Directive 2020-03-20 is a final rule addressing certain Boeing aircraft models including MD-11, MD-11F, 717-200, all 737-8 and 737-9, all 737-600/-700/-700C/-800/-900/-900ER series, certain 747-400 and 747-400F, certain 757 and 767, and all 777 airplanes. This directive requires revising the airplane flight manual to prohibit operations requiring less than 0.3 required navigational performance (RNP) within a specified geographic area for airplanes equipped with a Collins GLU-2100 multi-mode receiver (MMR) with certain software versions. The AD was issued due to reports of loss or degradation of GPS data affecting positional accuracy.
