Narrative:

On aug,sun/91 after the arrival of flight from brownwood, tx, it was noted that the right engine cowl flap door was hanging down. Further investigation determined that the cowl flap was not hooked up and pins and lock clips were in arms only. The cowl flap door was reconnected and operated normally. It was noted in the logbook that maintenance was done on the right engine propeller 2 flts before, also 2 different flcs had flown the plane with no noticeable temperature problem. It is unknown how the cowl flap was not hooked up. I believe if it did happen at maintenance it should be required that 2 mechanics look at all work performed on airplane.
