58-25-05 PIPER: Applies to Model PA-24 Aircraft, Serial Numbers 1 Through 336.
Compliance required by February 1, 1959.
It has been determined that an unsafe condition exists with respect to the door latch arrangement of the aircraft affected. At present it is not possible to open the cabin door from the inside if it has been locked on the outside. In order to preclude occupants becoming inadvertently locked inside the cabin of PA-24 aircraft in the case of some emergency, the main cabin door latch assembly must be modified to permit opening the door from inside the aircraft under all conditions.
(Item No. 1 of Piper Service Letter No. 305 dated October 1, 1958, presents an acceptable method of modifying the aircraft.)
