During rotation after the takeoff, the pilot’s seat back failed and went into the reclined position.

According to the technician, complete failure of the pilot’s seat could not be duplicated in the shop, but some slippage of the locking cylinder (P/N 0514213-2) for the pilot’s seat was noted.

The FAA Service Difficulty Program data base revealed two reports where the pilot’s seat back failed on the Cessna 172 aircraft.

Part total time-1,075 hours.
