Engine Power Loss During Go-Around Leads to Collision with Power Lines (N849B)

Big Bear City, CA, US

On September 5, 1999, a Beech 35-A33 (registration N849B) was involved in an aviation accident near Big Bear City, CA. Investigators recorded the probable cause as: The pilot's failure to follow the manufacturer's procedures to fully enrich the mixture, which induced an overly lean condition during full power application on the go-around and a resulting loss of power. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot performing a go-around after a wind gust experienced engine sputtering and total power loss. Despite enriching the mixture, power did not return, and the left wingtip struck power lines during an off-field landing.

Incident Summary

A pilot experienced a sudden wind gust while landing, causing the airplane to deviate from the extended runway centerline. The pilot applied full power and initiated a go-around. The airplane had difficulty climbing. At approximately 600 to 700 feet above ground level, the engine began sputtering and then completely lost power.

Sequence of Events

The pilot had the mixture leaned for cruise flight. After the wind gust, the pilot performed a go-around. As the airplane struggled to climb, the engine sputtered and quit. The pilot slightly enriched the mixture, which briefly restored engine power. Applying more mixture, however, did not elicit a response, and the engine lost all power. The pilot attempted to land in an empty lot. During the landing, the left wingtip collided with a series of power lines. The airplane came to rest in a field.

Examination Findings

Fuel levels were measured at approximately 1/2 to 3/4 full in both wing tanks. An examination of the engine revealed no discrepancies. Recorded weather data indicated a density altitude of 9,000 feet at the time of the accident. The Pilot's Operating Handbook (POH) for the airplane stated that in the event of a rough running engine or loss of engine power, the pilot should fully enrich the mixture, then lean as required.
