Engine Power Fluctuations During Takeoff Lead to Off-Airport Landing (N949BW)

Sarasota, FL, US

On June 9, 1995, a Piper PA-23-250 (registration N949BW) was involved in an aviation accident near Sarasota, FL. Investigators recorded the probable cause as: The pilot's improper draining of the fuel sumps during preflight inspection of the airplane. This resulted in a partial loss of engine power on the left engine on initial take off climb due to water contamination, subsequent forced landing, collapse of the… This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot experienced left engine power reduction during takeoff, drifted left, and landed in a field. FAA found water and contaminants in the left engine's fuel system but no mechanical failure.

Preflight and Takeoff

The pilot reported draining the fuel sumps during the preflight inspection and finding no water. On takeoff, the airplane became airborne at a speed just under 70 knots and remained in ground effect at an altitude of about 3 to 5 feet while accelerating to almost 80 knots.

Engine Power Loss and Aircraft Behavior

During the takeoff roll, the left engine experienced a reduction in power. The airplane began to settle but did not touch the runway. Subsequently, the left engine increased in power, then decreased again, and the airplane drifted to the left.

Off-Airport Landing

The pilot maneuvered the airplane over a fence, ditch, and trees before landing in a field. Upon landing, the main landing gear collapsed, and the airplane collided with trees.

Post-Accident Examination

An examination of the airplane by the Federal Aviation Administration (FAA) revealed no evidence of a mechanical failure of either engine. Water was present in the left engine gascolator sump bowl and internal baffle assembly. Congealed contaminants were found on the fuel screen. Additionally, the No. 2, 3, and 6 cylinder sparkplugs and piston domes appeared white in color.
