BW &R Pseudo-Patriot 24mm rocket

Second recent flight mishap. May be a problem with the Aerotech F63R-10 motors. Ejection charges seem to be igniting prematurely causing parachute to deploy on early accent. Getting the feeling that the delay charge is burning fast. I have followed the Aerotech assembly instructions precisely. Cant rule out operator error either. Had three good flights with this engine last year. Bought three more F63 motors last year and they may be bad? Need to contact Aerotech and see if age affects engines much.
