Engine Power Loss During Initial Climb Results in Fence Impact (N5646J)

Dayton, WA, US

On July 27, 1993, a Cessna 188A (registration N5646J) operated by Dayton Chemical, Inc was involved in an aviation accident near Dayton, WA. Investigators recorded the probable cause as: The loss of engine power due to a failed left magneto, which resulted in the aircraft descending and striking a fence during the initial climb after takeoff. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft experienced engine power loss at 50 feet during initial climb after takeoff. The pilot regained power but struck a fence before impacting the ground. An FAA inspector found no pre-accident engine malfunction, though the operator reported a left magneto failure.

What happened

The accident occurred during the initial climb phase immediately following takeoff. At an altitude of approximately 50 feet above ground level (AGL), the aircraft experienced a sudden loss of engine power. As the aircraft descended, the pilot managed to regain engine power. However, before reaching a safe altitude, the aircraft struck a fence. Following this impact, the aircraft continued its descent and impacted the ground.

The investigation

An FAA inspector examined the aircraft following the accident to determine the mechanical condition of the propulsion system. The inspection revealed no evidence of an engine malfunction or failure prior to the accident event. This finding suggests that the power loss was not caused by a pre-existing mechanical defect in the engine itself at the time of examination.

Findings

While the physical inspection did not identify a mechanical fault, operational data provided critical context. The operator reported that the left magneto had failed prior to or during the incident. This failure likely contributed to the loss of power experienced by the pilot during the critical initial climb phase.

Probable cause

The loss of engine power due to a failed left magneto, which resulted in the aircraft descending and striking a fence during the initial climb after takeoff.
