Probable cause

The pilot-in-command's decision to continue takeoff with a known deficiency in the airplane - low power on both engines which resulted from open compressor surge valves. The pilot subsequently failed to maintain airspeed while maneuvering in a turn resulting in an in-flight loss of control and a stall/spin.

Sequence of events

Analysis

The airplane had not flown since June, 1989. The flight had made 2 high-speed taxi operations before takeoff. Immediately after takeoff the flight called to land. The airplane was observed on downwind 200-800 ft AGL, 15-25 deg nose high. The airplane then stalled. The compressor surge valves for the left and right engines were found in the open position.
