Introduction
Shortly after takeoff, the pilot raised the landing gear. Immediately thereafter, the pilot noted that the gear motor circuit breaker had popped. Attempts to lower the landing gear using the emergency extension procedures were unsuccessful.
Sequence of Events
Unable to extend the landing gear, the pilot executed a landing with the gear retracted. The aircraft touched down and slid to a stop on grass, coming to rest on its belly.
Investigation Findings
Post-accident examination revealed that the aircraft's hydraulic system reservoir was empty. The landing gear motor was seized and would not rotate. No evidence of hydraulic fluid leakage was found on the aircraft or in the surrounding area. After the hydraulic system was re-serviced with fluid, it performed normally under test conditions.
Outcome
The aircraft sustained damage as a result of the gear-up landing. The investigation did not provide additional details regarding the aircraft, occupants, or specific circumstances.
