AD Watch

The FAA has issued a Notice of Proposed Rulemaking (NPRM) that would replace a current Airworthiness Directive (AD) requiring a one-time inspection of the fuel boost pump wiring inside and outside the boost pump reservoir and repair or replacement of the wiring as necessary on certain Cessna Aircraft Company Model 441 airplanes. This proposed AD would retain the actions required in AD 2002-09-13, make the one-time inspection repetitive, require the inspection and possible replacement of the wire harness, lead wires and fuel boost pump on Model F406 airplanes, and require eventual installation of an improved design wire harness and fuel boost pump as terminating action for the repetitive inspections. The actions specified by this proposed AD are intended to detect, correct, and prevent chafing and/or arcing fuel boost pump wiring, which could result in arcing within the wing fuel storage system. Such a condition could lead to ignition of explosive vapor within the fuel storage system. Submit your comments to the FAA by December 30, 2002.

The FAA has adopted an AD that applies to certain Pilatus Aircraft Ltd. (Pilatus) Model PC-6 airplanes. This AD requires inspection of the aileron assembly for correct configuration and modification as necessary. This AD is intended to correct improper aileron assembly configuration, which could result in failure of the aileron mass balance weight. Such failure could lead to loss of control of the airplane. This AD becomes effective on December 6, 2002.
