A Convair CV-240, N156PA, experienced a significant accident during a simulated single engine ILS approach at Boise Air Terminal. The aircraft, operated as a flight check for an initial airline pilot’s rating, landed with all landing gear retracted. The FAA air carrier operations inspector observed the pilot, check pilot, and jumpseat observer, who were not injured. The aircraft sustained substantial damage to the runway and the airport. The pilot’s failure to extend the landing gear and the check pilot’s inadequate supervision contributed to the accident.A Convair CV-240, N156PA, experienced a significant accident during a simulated single engine ILS approach at Boise Air Terminal.

Description

A Convair CV-240, N156PA, landed with all landing gear retracted, during a simulated single engine ILS approach Boise Air Terminal, ID. The flight was being operated as a flight check for an initial airline pilot’s rating and CV/240 type rating. An FAA air carrier operations inspector was conducting the flight check and occupied the copilot’s seat. The airplane had departed Boise at approximately 11:06 on a local VFR flight plan in visual meteorological conditions. The pilot, check pilot and jumpseat observer were not injured. The airplane sustained substantial damage and the airport runway sustained damage. FAA air traffic controllers reported the airplane to have been executing a VOR/DME approach to Boise runway 10R and continued to touch down with the landing gear in the retracted position. Neither landing clearance nor contact with the Boise tower was established at the time of the accident. PROBABLE CAUSE: “The pilot’s failure to extend the landing gear, and the check pilot’s inadequate supervision. A factor in the accident was the pilot’s inadequate upgrade training by the company.”

Primary Cause

Pilot’s failure to extend landing gear and inadequate supervision by the check pilot.Pilot’s failure to extend landing gear and inadequate supervision by the check pilot.
