Airworthiness Directives; Piper Aircraft, Inc., Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for all Piper Aircraft, Inc., (Piper) Models PA-46-350P (Malibu Mirage), PA-46R-350T (Malibu Matrix), and PA-46-500TP (Malibu Meridian) airplanes. This proposed AD was prompted by a finding of several airplanes with wing assemblies that did not have the proper stall warning heater modification design. Without the proper stall warning heat control modification kit installed, during flights into icing conditions with the landing gear down, ice can form on the stall vane, which may result in failure of the stall warning system. This proposed AD would require identifying and correcting nonconforming stall warning heat control systems. The FAA is proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by a report that threaded fuel couplings were incorrectly installed at final assembly and in service. This proposed AD would require repetitive functional tests of the auxiliary power unit (APU) fuel feed line shroud, a general visual inspection of the APU feed line shroud for any loose couplings; and tightening any loose couplings, which would terminate the repetitive functional tests. The FAA is proposing this AD to address the unsafe condition on these products.
