Old but interesting GV incident
Feb. 14, 2002 West Palm Beach, Florida, U.S. Gulfstream V
Soon after departure, the flight crew requested clearance to return to the airport because the landing gear had not retracted on
command. As the airplane was flared for landing, the ground spoilers deployed. The airplane landed hard, and the right-main landing gear
collapsed. The report said that wooden sticks were found in the weight-on-wheels switches for both main landing gear. The airplane was
on jacks for a tire change when a maintenance technician used the sticks to disable the weight-on-wheels system so that he could access
the maintenance-data-acquisition unit to check an overspeed message. The sticks were not removed after maintenance was completed.
As a result, the airplane remained in ground mode, and the ground spoilers deployed when the crew moved the throttle levers to idle
during the flare.
