Falcon Field Airport
Aircraft Accident/Incident Report

Mesa, Arizona 85215
Wednesday, October 29, 2008 19:59 MST

NTSB Narrative Summary Released at Completion of Accident

At the conclusion of the business flight, the pilot placed the landing gear selector in the down position. The gear did not extend. Then, the pilot attempted to extend the gear using the emergency procedure, and he was similarly unsuccessful. The pilot landed with the gear partially extended. The airplane swerved off the runway and was substantially damaged. An examination of the landing gear system revealed that an aluminum hydraulic line had ruptured at a 45-degree bend near the location of an Adel clamp. The subsequent loss of fluid rendered the primary and emergency gear extension systems inoperative.

NTSB Probable Cause Narrative

The failure of the hydraulic landing gear extension systems due to a ruptured line.
