St. George, UT, US

On April 27, 2001, a Piper PA-31-350 (registration N27367) was involved in an aviation accident near St. George, UT. Investigators recorded the probable cause as: the pilot's failure to sump all the fuel drains during preflight and the subsequent loss of power in the right engine during takeoff, the pilot feathering the wrong engine's propeller during the forced landing, the pilot improperly raising the landing gear… This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot experienced a right engine power loss after takeoff on runway 16, located on a narrow mesa. The pilot feathered the left engine and performed a forced landing. Investigation found water in the fuel system and improperly installed sump valve, but no engine anomalies.

Departure and Engine Failure

The pilot departed on runway 16, situated on a narrow mesa with surrounding terrain approximately 300 to 350 feet below. Immediately after takeoff, the pilot reported a loss of power on the right engine. In response, the pilot feathered the propeller on the left engine and executed a forced landing.

Landing Gear Operation

During the forced landing, the pilot raised the landing gear with runway remaining. The FAA Advisory Circular 61-21A, Flight Training Handbook, notes that landing gear should not be raised until a safe landing can no longer be made on the remaining portion of the runway.

Postaccident Examination

Postaccident examination of both engines revealed no mechanical anomalies that could have affected their performance. Recovery personnel noted that both propellers were "dramatically" bent in the direction opposite to rotation.

Fuel System Inspection

Further inspection found that the right wing root fuel sump valve was installed improperly, making it impossible to sump. When the valve was removed, the fuel sample was found to contain approximately 25% water.

Wind Conditions

At the time of the attempted takeoff, the wind was from 130 degrees at 21 knots, gusting to 31 knots. The direct crosswind component was calculated to be 16 knots, which was within the airplane's demonstrated crosswind limit of 20 knots.
