Loss of Power During Climb Results in Field Landing (N4878V)

Medford, OR, US

On March 27, 1987, a Bellanca 17-30 (registration N4878V) was involved in an aviation accident near Medford, OR. Investigators recorded the probable cause as: The pilot's inability to maintain adequate altitude after a total loss of engine power during climb, which resulted in an off-airport landing and subsequent impact with a ditch. The underlying cause of the power loss remains undetermined. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot experienced a sudden and total loss of engine power while climbing to cruise altitude. Unable to reach the departure airport, the pilot executed a turnback and landed in a nearby field, where the aircraft struck a ditch during rollout.

What happened

The flight was underway when the pilot reported a total and sudden loss of engine power. This event occurred while the aircraft was climbing toward cruise altitude at an indicated altitude of approximately 3,500 feet mean sea level (MSL).

Upon experiencing the failure, the pilot immediately initiated a 180-degree turn to return to the departure airport. However, it became apparent that the aircraft would not be able to reach the runway due to insufficient altitude or performance margins. Consequently, the pilot elected to divert and land in an adjacent field.

During the landing rollout, at a speed of approximately 20 miles per hour (MPH), the aircraft struck a ditch. The impact occurred after the initial touchdown but before the aircraft could come to a complete stop on level ground.

The investigation

A thorough examination was conducted to determine the mechanical cause of the power loss. Investigators analyzed the engine components and fuel systems for any anomalies that might explain the sudden failure. Despite these efforts, no mechanical defect or external factor could be identified as the reason for the loss of power.

Probable cause

The pilot's inability to maintain adequate altitude after a total loss of engine power during climb, which resulted in an off-airport landing and subsequent impact with a ditch. The underlying cause of the power loss remains undetermined.
