Guthrie, OK, US

On April 15, 1984, a Beech A23-19 (registration N2385W) was involved in an aviation accident near Guthrie, OK. Investigators recorded the probable cause as: The pilot's failure to use carburetor heat during the descent and approach, which resulted in carburetor ice-induced engine power loss. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An aircraft descended below the glideslope and experienced engine unresponsiveness upon power application, resulting in a hard landing and impact with a tree while light rain fell.

What happened

The pilot was conducting an approach to land when the aircraft descended below the desired glideslope. Recognizing the situation, the pilot applied additional power to the engine; however, the engine did not respond as expected. The aircraft touched down hard and short of the runway. Following the initial impact, the left wing struck a tree.

The investigation

During the post-accident review, the pilot stated that carburetor heat was not used during either the descent or the approach phase. At the time of the incident, light rain was falling in the area.

Findings

The sequence of events indicates a loss of engine power during a critical phase of flight. The lack of carburetor heat usage during descent in rainy conditions likely contributed to the engine failure. The aircraft's inability to maintain altitude and subsequent hard landing resulted in structural damage upon contact with terrain.

Safety message

Pilots should be aware that carburetor ice can form even in mild weather conditions, particularly when humidity is high or precipitation is present. Using carburetor heat as a preventive measure during descent and approach can help avoid power loss.

Probable cause

The pilot's failure to use carburetor heat during the descent and approach, which resulted in carburetor ice-induced engine power loss.
