The FAA has proposed issuing an airworthiness directive (AD) affecting some Piper PA-31 Navajo twin-engine airplanes to require repetitive inspections for fatigue cracking in the fuselage bulkhead at the horizontal stabilizer front spar attachment, and any necessary repairs.
The proposed AD is estimated to pertain to 955 model PA-31, PA-31-300, PA-31-325, and PA-31-350 airplanes. It was prompted by fatigue cracking in the fuselage station (FS) 332.00 bulkhead common to the horizontal stabilizer front spar attachment, the FAA said.
Complying with the proposed AD is expected to cost $85 for the inspection and an additional $2,506 if repairs are needed.
AOPA is reviewing the proposed AD and encourages members to contact the AOPA Pilot Information Center if they have specific comments or concerns about the proposal. The FAA will accept comments until Feb. 17.
