Federal Aviation Administration November 3, 2020 – Federal Register Recent Federal Regulation Documents

The FAA is adopting a new airworthiness directive (AD) for certain Pilatus Aircraft Ltd Model PC-24 airplanes. This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the vinyl grommets on the upper panel assembly on the left-hand (LH) and right-hand (RH) emergency exits becoming rigid after exposure to low temperatures, which could result in failure of the emergency exits to open during an evacuation. This AD requires replacing the grommets. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C1 and AS332L1 helicopters. This AD was prompted by a report that the affected helicopters use the same ``flight/ground'' logic signal, instead of independent redundant signals. This AD requires amending the emergency procedures of the existing rotorcraft flight manual (RFM) for your helicopter, a wiring modification of the ``flight/ground'' logic signal source of the attitude and heading reference system (AHRS) 1, and then removal of the amendment to the existing RFM for your helicopter. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain Polskie Zaklady Lotnicze Sp. z o.o. Model PZL M28 05 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as defective thermo-shrinkable tubes installed on the electrical harnesses located in the fuel tanks. This AD requires a one-time inspection of the electrical harnesses located in the fuel tanks and, depending on findings, replacement of the affected harness. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA proposes to supersede Airworthiness Directive (AD) 2020-04-22, which applies to certain Dassault Aviation Model FALCON 2000EX airplanes. AD 2020-04-22 requires revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2020-04-22, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
