NTSB narrative
During an attempted takeoff from a 2,100-foot turf covered runway, a Cessna 170B veered to the right, struck a runway light, crossed an unpaved access road and then impacted the west side of a hangar located 1,200 feet from the approach end of the runway. It did not appear that there was any attempt by the pilot to stop or turn the airplane prior to the impact. The engine seemed to be producing full power, and the pilot, could be seen sitting erect and looking straight ahead. The pilot was ejected during the impact sequence and both the pilot and his passenger were seriously injured. During the wreckage examination no evidence of any preimpact malfunctions of the airplane were discovered. The airplane had been registered to the pilot since June 29, 1964, and had been modified after leaving the factory. A more powerful engine, constant speed propeller, wing "fences," and vertically adjustable pilot's seat, from another airplane type, had been installed; however, no information regarding any alterations to the accident airplane were discovered in Federal Aviation Administration (FAA) records. No registration, certificate of airworthiness, engine maintenance log, propeller maintenance log, or pilot logbooks were discovered, or provided to the National Transportation Safety Board during the investigation. No "Pilot/Operator Aircraft Accident Report, NTSB Form 6120.1" was received and the pilot and passenger had no recollection of the accident.
Probable cause
The pilot's failure to maintain directional control during takeoff.

- 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, coordinates. 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.
