    Abstract: A positive locking keeper for use with an aircraft panel latch assembly having a hook for engaging the positive locking keeper includes a keeper housing having a central opening, and a coupling having a head and a shaft extending therefrom. The head engages the latch assembly and the shaft extends through the housing with the head disposed on the first side. A detent pin is disposed within an aperture of the keeper housing. The positive locking keeper also includes a nut positioned on the second side of the keeper housing. The shaft engaged the nut. The nut includes indentations on a peripheral edge to receive a portion of the detent pin. In a first position, the detent pin engages one of the indentations and prevents rotation of the nut.
