The pilot’s failure to maintain sufficient clearance from a large multi-engine airplane during taxi operations.
Investigator assessment
Analysis narrative
The pilot reported that while he was approaching a taxiway intersection, a large, twin engine, turboprop airplane was undergoing a maintenance engine run on the adjacent run-up area. The propeller blast from the turboprop airplane lifted the left wing and tail of the airplane, and the airplane nosed over, coming to rest inverted. The airplane’s fuselage, empennage, both wings, vertical stabilizer, and rudder were substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. According to the pilot, the tower controller did not issue any cautionary advisories for the turboprop airplane activity to the pilot with the takeoff clearance.
