NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The right wing impacted the pavement after encountering jet blast from a transport category airplane taxiing onto a runway. The accident airplane had been instructed by ground control to taxi along a route that placed it behind a Boeing 737, which was holding short of the runway for a takeoff clearance. The certified flight instructor (CFI) directed his student to taxi as far to the right side of the 75-foot-wide taxiway as possible to avoid the jet blast of the Boeing 737. As their airplane passed behind the jet, the Boeing spooled up its engines and proceeded onto the runway for takeoff. The CFI and student were on the ground controller's frequency, and were not aware that the jet had been cleared for takeoff by the local controller on tower frequency. Controllers issued no safety alerts or cautionary advisories as instructed by Air Traffic Control Order 7110.65N, 3-1-4. The airplane's left wing rose into the air while the right impacted the pavement twice. The propeller also struck the pavement. Ground scars and a paint streak were near the right edge and outside of the taxiway boundary line.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

the certified flight instructor's failure to maintain an adequate distance from a jet during taxi. A factor was the local/ground controller's failure to issue a safety alert or cautionary advisory to the pilot with regards to the jet blast of the departing Boeing 737.
