Cedar City Regional Airport
Aircraft Accident/Incident Report
Cedar City, Utah 84720
Wednesday, October 21, 2009 10:15 MDT
NTSB Narrative Summary Released at Completion of Accident
Upon arrival over the destination airport during a positioning flight, the pilot attempted to extend the airplane's landing gear. Only the nose gear and the left main landing gear locked in the down position. The pilot reported that he performed the emergency gear extension procedure specified in the airplane's flight manual, but the right main gear did not lock down. The pilot returned to the departure airport and landed. During rollout, the right main landing gear collapsed and the airplane slid off the runway resulting in substantial airframe damage. An examination of the airplane revealed that an accumulator/regulator in the extension system had malfunctioned. In addition, an incorrect priority valve was installed and precluded the gear from locking down.
NTSB Probable Cause Narrative
The failure of the landing gear accumulator/regulator and the installation of the improper priority valve, which precluded the landing gear from extending and locking into place.
