AD 2020-23-13 Prompted By False Activation Of The Stall Warning System

The FAA is adopting a new airworthiness directive (AD) for all ATR-GIE Avions de Transport Regional Airplanes Model ATR42-200, -300, and -320 airplanes. This AD was prompted by false activation of the stall warning system due to wiring damage on the wire bundle between an angle of attack (AOA) probe and the crew alerting computer. This AD requires a one-time inspection for discrepancies of the wire bundles between the left- and right-hand AOA probes and the crew alerting computer, and, depending on findings, applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products. This AD becomes effective December 3, 2020.

AD 2020-24-02 Applies To All The Boeing Company Model 737-8 and 737-9 (737 MAX) Airplanes

The FAA is superseding Airworthiness Directive (AD) 2018-23-51, which applied to all The Boeing Company Model 737-8 and 737-9 (737 MAX) airplanes. AD 2018-23-51 required revising certificate limitations and operating procedures of the Airplane Flight Manual (AFM) to provide the flightcrew with runaway horizontal stabilizer trim procedures to follow under certain conditions. This AD requires installing new flight control computer (FCC) software, revising the existing AFM to incorporate new and revised flightcrew procedures, installing new MAX display system (MDS) software, changing the horizontal stabilizer trim wire routing installations, completing an angle of attack (AOA) sensor system test, and performing an operational readiness flight. This AD also applies to a narrower set of airplanes than the superseded AD, and only allows operation (dispatch) of an airplane with certain inoperative systems if specific, more restrictive, provisions are incorpora

Aircraft Will Be Additionally Equipped With Controller-Pilot Digital Private Communications System

SSJ100 aircraft has successfully completed test flights and proved the performance capability of ATN system in real conditions in Europe. The installation of this system is relevant primarily for the operators flying to EU countries. Equipping of all civil passenger aircraft with ATN system starting from February, 2020 is a mandatory requirement of the European aviation authorities for flight operations in various European countries above FL285.
