NTSB narrative
Shortly after takeoff during level cruise flight at 1,500 feet, the engine rpm began decreasing. The pilot applied full throttle but the engine rpm continued decreasing to engine failure. While descending for a forced landing in a field, the airplane collided with and remained suspended in trees. Post crash examination of the engine revealed that the flexible oil radiator hose from the engine driven oil pump to the oil cooler was failed about 27 inches forward of the engine driven oil pump outlet. Review of the maintenance records revealed that the failed hose was last replaced on May 1, 1977, in accordance with a non-repetitive Airworthiness Directive. The airplane had accumulated 2,388.1 hours since replacement 20 years 1 month and 25 days earlier. The hose is a on-condition item.
Probable cause
Failure of the oil cooler radiator hose which resulted in oil exhaustion and subsequent engine failure. Contributing to the accident was the failure of the FAA to require a recurrent detailed examination and or require those hoses be life limited to prevent failure. Also, unsuitable terrain encountered by the pilot during the emergency descent for a forced landing.

- 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.
