Accident occurred Tuesday, April 24, 2012 in Sioux Falls, SD

NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot stated that he was unable to fully retract the landing gear after takeoff and the landing gear position indicator transition light remained illuminated. He tried to manually extend the landing gear, but the crank arm was difficult to turn. Unable to fully extend or retract the landing gear, the pilot diverted to a nearby airport where he performed a landing with the gear partially extended, which resulted in substantial damage to the airplane. During the postaccident recovery and examination of the airplane, the landing gear was cycled repeatedly using the airplaneā€™s normal (electrical) landing gear system and operated normally. Although the manual landing gear extension handle was difficult to turn during postaccident testing, this would not explain why the gear would not retract. Postaccident examination of the landing gear system could not duplicate the condition that resulted in the partial gear-up landing.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The failure of the normal and emergency landing gear system to fully retract or extend the landing gear for reasons that could not be determined during postaccident examinations, which resulted in a partial gear-up landing.
