What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot was landing this aircraft at Hilton Head Island Airport, in south carolina. He attempted to put the landing gear down. The landing gear would not go down. The pilot flew past the tower and requested a visual. The tower stated the gear was not down and the left gear door was partically open. The pilot tried the emergency extension system, three times, trying to pump the gear down without results. The pilot determined the reservoir was empty of fluid that was needed to use the emergency extension of the landing gear. The pilot made a gear up landing. After examination of the airplane in a hangar with the landing put in the down, extended position, it was determined the left main gear door actuator retaining ring had come out of place, and the actuator had separated from the rod end. All the fluid then came out of the entire system, rendering gear extension by either the normal or emergency methods impossible. The part number of the left main gear door actuator is #1281028-1, serial number #2744 and assembly date 3/74. The last annual inspection was accomplished on 11/2/2011.there is an STC for removal of these gear doors and associated actuators which improves the system, but it had not been accomplished.
