1989-09-17: DE Havilland BEAVER DHC-2 MK.1 (N5163G) — Kapowsin Air Sports — Kapowsin, WA

Kapowsin, WA, US

On September 17, 1989, a DE Havilland BEAVER DHC-2 MK.1 (registration N5163G) operated by Kapowsin Air Sports was involved in an aviation accident near Kapowsin, WA. Investigators recorded the probable cause as: The pilot's inability to maintain control during a forced landing following an in-flight engine shutdown, which was not attributable to mechanical failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.

An aircraft experienced an engine failure at 200 feet during initial climb. The pilot restarted the engine briefly before a forced landing resulted in a nose-over.

What happened

The flight began with all system and engine gauges indicating normal operation. During the initial climb phase, shortly after takeoff, the aircraft reached an altitude of approximately 200 feet above ground level (AGL). At this point, the engine suddenly quit, resulting in a loss of power.

In response to the emergency, the pilot attempted to switch fuel tanks and restart the engine. The engine did restart and ran for approximately ten seconds before failing again. With no further power available, the pilot executed a forced landing. During the landing roll on the ground, the airplane nosed over, causing significant damage to the aircraft structure.

The investigation

A post-crash inspection of the engine was conducted to determine the cause of the failure. The examination did not reveal any evidence of mechanical failure or malfunction within the engine components. This finding suggests that the in-flight shutdown was likely due to an external factor, such as fuel supply interruption, rather than an internal mechanical defect.

Findings

The sequence of events indicates a sudden loss of engine power during the critical initial climb phase. The brief restart capability suggests that the issue may have been related to fuel flow or selection, although the specific root cause was not definitively identified through mechanical inspection alone. The subsequent nose-over during the forced landing highlights the challenges of managing an aircraft with no power in a confined area.

Safety message

Pilots should be aware of the critical nature of the initial climb phase and ensure that fuel system checks are thorough before departure. In the event of an engine failure, immediate and correct action regarding fuel selection and emergency procedures is essential to maximize the chances of a safe outcome.

Probable cause

The pilot's inability to maintain control during a forced landing following an in-flight engine shutdown, which was not attributable to mechanical failure.
