## Discrepancy

UPON GEAR RETRACTION THE PISTON HOUSING FOR THE PISTON RACK ON THE ROTARY ACTUATOR CRACKED AT THE THREADED END CAP. ONCE HOUSING CRACKED FLUID ESCAPED CAUSING THE MAIN LANDING GEAR TO BE UNSECURED. PILOT MOVED GEAR HANDLE TO THE DOWN POSITION AND WAS ABLE TO SECURE THE NOSE GEAR DOWN AND LOCKED WITH THE HAND PUMP. MAIN LANDING GEAR STILL UNSECURED AT MID TRAVEL.
