1985-09-19: Cessna 177RG (N800JH) — John M. Greacen — Neola, WV

Neola, WV, US

On September 19, 1985, a Cessna 177RG (registration N800JH) operated by John M. Greacen was involved in an aviation accident near Neola, WV. Investigators recorded the probable cause as: The loss of engine power due to a cracked crankcase beneath the number 1 cylinder, which necessitated a forced landing that resulted in a collision with trees. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft experienced an engine power loss while leveling at cruise altitude, prompting a forced landing in a field where it struck trees during the rollout.

What happened

The flight was proceeding normally until the aircraft reached its intended cruise altitude. While the pilot was in the process of leveling off, the engine suddenly lost power. With no immediate option to maintain altitude or return to the departure point, the pilot initiated a forced landing procedure. The aircraft descended and touched down in an open field. However, the landing roll did not conclude safely within the boundaries of the field; instead, the aircraft continued forward and collided with small trees located at the far end of the landing area.

The investigation

Following the accident, investigators conducted a post-crash examination of the airframe and propulsion system to determine the root cause of the power loss. A detailed inspection of the engine revealed significant internal damage consistent with a catastrophic mechanical failure. Specifically, examiners found a distinct fracture in the engine's structural housing. The damage was identified as a 3-inch crack located in the crankcase directly beneath the number 1 cylinder.

Findings

The sequence of events indicates that the primary factor leading to the accident was the sudden loss of engine power during a critical phase of flight. The mechanical failure of the crankcase prevented the engine from continuing to operate, forcing the pilot to execute an emergency landing in unprepared terrain. The subsequent impact with trees at the end of the field was a direct result of the aircraft's inability to stop within the available distance after touchdown.

Probable cause

The loss of engine power due to a cracked crankcase beneath the number 1 cylinder, which necessitated a forced landing that resulted in a collision with trees.
