NTSB narrative
As the pilot started taxiing before takeoff, he used heavy throttle application to get the airplane to move up an incline, from where the airplane had been parked, to reach a taxiway. When the airplane reached the top of the incline, the nosewheel bounced, and the pilot lost control. The airplane continued moving and impacted five stationary airplanes before coming to a stop. Subsequent to the accident, the throttle, brakes, magneto switch, and mixture were checked, and all were found to operate normally. The throttle was a vernier type, and the brakes were of the hand brake type. Until operating this airplane, the pilot had been operating airplanes with a friction lock type throttle and toe brakes. He had 16 hours total time in the accident airplane with about 6 hours solo.
Probable cause
the pilot's improper use of the throttle control friction lock, and his inadequate remedial action. Related factors were his lack of experience in type of aircraft, the pilot's habit interference, and the presence of parked (standing) aircraft.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
