Pioneer 400, G-TLOY


During a test flight for the initial issue of a Permit to Fly, the pilot reported a loss of pitch control authority during a go-around from low speed. On the subsequent approach the pilot delayed lowering the landing gear to ensure he could land on the airstrip, but it was not fully extended by the time the aircraft touched down and the gear collapsed during the landing roll. Prior to the flight 50% of the length of the elevator trim tab Gurney flap had been removed to correct a perceived problem of limited forward elevator authority during cruise, and post-accident inspection revealed that the elevator cables had low tension. After repair the aircraft was test flown by the LAA’s Chief Test Pilot, who considered the design was acceptable without further change.
