On February 21, 1994, the right engine of N3433Y experienced a misfire and loss of power while on final approach to Spokane, WA. The airplane was grounded for maintenance and the right engine was removed and replaced with an overhauled engine from Precision Airmotive. Precision Airmotive reported that the overhaul was completed and approved for service on December 20, 1993 and preserved for short term storage. Prior to the overhaul the engine had been on the shelf in long term storage.
At the time of the accident, the operator reported that the engine had accumulated a total time of 15 hours since the overhaul.
On March 18, 01:53 hours, the captain reported to the Spokane controller that the flight was ready for takeoff on runway 21. The controller instructed the flight to, after takeoff, fly a heading of 215 degrees to Portland, and it was cleared for takeoff. Shortly after takeoff the crew were forced to shut down the right engine because of a failure. They tried to return to the airport but the plane collided with the terrain in an open level field located 3,450 feet from the end of runway 21 and 900 feet to the right of runway centerline. The airplane was lying on its belly, with the main landing gear retracted. The entire fuselage and cargo, cockpit, and inboard section of both wings was consumed by fire.

PROBABLE CAUSE: "The failure of the pilot-in-command to maintain airspeed. Factors to the accident were: cylinder fatigue, dark night and stall encountered."
