A pilot performing a low and slow sightseeing flight experienced engine overheating, executed a precautionary landing on a dirt road, and collided with a cattle guard and gate. Post-crash examination found an unsecured oil dipstick.

Overview

A local sightseeing flight ended in a collision with a cattle guard and gate after the pilot executed a precautionary landing due to engine overheating. The aircraft, which had been flying at a low altitude and slow speed with a nose-high attitude, encountered the engine issue and was landed on a dirt road. During the landing rollout, the aircraft ballooned and touched down over a rise in the road. After cresting a second hill, it collided with a cattle guard and gate.

Sequence of Events

According to the pilot, the flight was a local sightseeing trip. The pilot reported flying low and slow at a nose-high attitude when the engine began to overheat and did not cool off. In response, the pilot elected to perform a precautionary landing on a dirt road. The aircraft bounced or ballooned during the landing and touched down over a rise in the road. It then crested a second hill before striking a cattle guard and gate.

Post-Crash Examination

A post-crash examination of the aircraft revealed that the oil dipstick was not properly secured. As a result, oil had escaped from the oil filler tube. This condition likely contributed to the engine overheating, although no causal analysis is provided in the source.

Aircraft and Occupants

The specific aircraft type, registration, number of engines, and operator are not specified. The source indicates a pilot and passenger were on board. No information regarding injuries or damage to the aircraft beyond the collision and oil leak is provided.
