Narrative:
On January 19, 1996, about 09:23 EST (Eastern Standard Time), a Mitsubishi MU-2B-60, N50KW, registered to and operated by Bankair, Inc., experienced a loss of control while on short final approach to land at the Columbia Metropolitan Airport, West Columbia, South Carolina. Visual meteorological conditions prevailed at the time and an IFR clearance was received for the 14 CFR Part 91 maintenance test flight. The airplane was destroyed and the airline transport-rated pilot and a passenger/company mechanic were seriously injured. The flight originated about 09:05 from the accident airport.

About 7 minutes after take-off, the pilot advised Air Traffic Control that he was returning due to having shut down one (the left) engine. The aircraft was vectored for landing on Runway 29 at Columbia Metropolitan Airport, South Carolina, but on short final, whilst descending through about 100 feet., it rolled to the left and crashed inverted beside the runway.

The accident happened in daylight (09:23 EST) and in fine weather, wind 250 degrees/19 knots, gusting to 29 knots. The aircraft was performing a maintenance test flight. Both engines had recently been installed following 'hot section' work and had been started up the day after installation with no discrepancies being noted. Before takeoff for the test flight the pilot performed an NTS check on each engine with no discrepancies being noted.

During the flight the pilot performed an NTS check on the left engine. However, after shut down, two attempts to restart the left engine were unsuccessful. Each time the propeller came out of the feathered position and started to rotate but there was no fuel flow or ignition. A post accident examination of the left engine and accessories revealed no evidence of pre-impact failure or malfunction but the left engine fuel shutoff valve was found in the 'closed' position and no fuel was found aft of the fuel shutoff valve. The pilot stated that he has no recollection of the accident.

The NTSB determined that the probable cause of the accident was a total loss of power on one engine for undetermined reasons and the pilot's failure to maintain airspeed (VMC) resulting in a loss of control. Contributing to the accident was the wind gusts encountered while on final approach to land.

Registration N50KW belatedly cancelled by the FAA on December 17 2003 (seven years later) as "destroyed"
