Overview
On an unstated date, the crew of a Lear 23—the first model of the type—departed on a local test flight from Wichita Airport. The purpose of the flight was to conduct tests. During the takeoff roll, the aircraft encountered difficulties in gaining altitude. It went out of control, struck the ground, rolled for several yards, and came to rest in flames in a wasteland. The aircraft was destroyed in the impact and subsequent fire.
Injuries and Damage
Both pilots on board were seriously injured. The aircraft sustained catastrophic damage and was classified as destroyed.
Probable Cause
According to the official investigation, the probable cause of the accident was inadequate pre-flight preparation and/or planning on the part of the flying crew, who failed to use or incorrectly used miscellaneous equipment. Specifically, during the test flight, while simulating a failure of the left engine, the crew attempted to take off with the spoilers extended.
