This is preliminary information, subject to change, and may contain errors. Any errors in this report will be corrected when the final report has been completed. NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
On May 13, 2013, about 1245 Pacific daylight time, a Gates Learjet 35A, N22MS, overran the runway during landing at McMinnville Municipal Airport, McMinnville, Oregon. The airplane was registered to Evergreen Equity, Inc., and operated by Evergreen International Aviation, Inc., under the provisions of 14 Code of Federal Regulations Part 91, as a post-maintenance repositioning flight. The airline transport pilot, commercial rated copilot, and passenger were not injured. The airplane sustained substantial damage to both wings, the forward fuselage, and the pressure vessel during the accident sequence. The cross-country flight departed Grand Junction Regional Airport, Grand Junction, Colorado, about 1145 mountain daylight time, with a planned destination of McMinnville. Visual meteorological conditions prevailed at McMinnville, and an instrument flight rules flight plan had been filed.
The NTSB investigator traveled in support of this investigation, and performed an examination of the engine and airframe subsequent to recovery.
The airplane had just undergone a flight management system (FMS) upgrade at a maintenance facility in Grand Junction, and this was both its first flight, and its home base return flight, following the upgrade.
The pilot reported that the flight and landing approach were uneventful. As the airplane touched down on runway 22, the pilot deployed the spoilers, and then pulled the power levers to the thrust reverser detent position; however, the deploy indicators did not illuminate. He then recycled the thrust levers back into the detent, but again the reversers did not deploy. Both the pilot and copilot attempted to troubleshoot as the airplane continued along the runway. The pilot then applied pressure to the foot pedal brakes, but did not feel a response; the copilot also attempted, but reported that the pedals felt loose and the airplane did not slow down. As the airplane approached the threshold, the pilot engaged the steering lock switch, and attempted to steer the nose wheel, but the airplane did not respond. Just prior to reaching the runway end, he activated the emergency braking lever; however, the airplane rolled off the runway end, through a set of instrument landing system antennas, and down an embankment.
Subsequent examination revealed that the mounting screws for both the left and right main landing gear squat switches were loose, such that the switches had backed away from their mounting pads.
McMINNVILLE, Oregon — A small jet airplane has run off the end of the runway at the McMinnville Municipal Airport.
McMinnville Fire Department Division Chief Debbie McDermott says the Evergreen International Aviation, Inc., Lear jet was unable to stop and ended up in a ditch at the end of the runway Monday afternoon.
McDermott says all three people aboard were able to get out unhurt, and there appeared to be little damage.
A receptionist at Evergreen said no one was available to comment.
