Aircraft Accident/Incident Report

Monett, Missouri 65723
Thursday, May 4, 2006 19:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane was substantially damaged when the landing gear failed to extend properly and the pilot executed an emergency landing. The pilot reported he heard a "pop" and smelled hydraulic fluid during cruise flight. He attempted to lower the landing gear, however, only the right main gear extended properly. The nose gear and left main gear remained retracted. Use of the emergency landing gear extension system was not successful. The pilot set up for an emergency landing and elected to secure the engine while on short final. He stated that with the resulting loss of engine power, the airplane "dropped out of the sky" and subsequently landed short of the runway. The extended right main landing gear collapsed. A post accident inspection revealed that a hydraulic line on the firewall had ruptured. In addition, the piston rod within both the nose and left main landing gear extension cylinders was bent preventing free movement. The landing gear system utilized hydraulic pressure to raise and hold the gear in the retracted position. No up-locks were installed.

NTSB Probable Cause Narrative

Rupture of the hydraulic hose and deformation of the hydraulic cylinder piston rods for undetermined reasons, which resulted in a failure of the landing gear extension system. Contributing factors were the pilot's premature shutdown of the engine on short final, the resulting inability to maintain a proper glidepath to the runway, and the unsuitable terrain adjacent to the runway resulting in collapse of the right main landing gear.
