Event Description
At 1727, the aircraft was cleared for takeoff on Runway 19, heading south. The engines were run up to a manifold pressure of 15 inches of mercury and the ignition was checked on both magnetos of each engine. Takeoff commenced with manifold pressure increased to 52 inches of mercury. Ground witnesses observed the takeoff run as longer than usual for that model. Shortly after lift-off, tower personnel and several witnesses saw puffs of black smoke from the left engine. At an estimated altitude of 200–300 feet, the left engine began to misfire. The landing gear was raised and confirmed in position. The left engine's misfiring worsened, and the left propeller was feathered.
Maneuvering and Impact
The terrain ahead was flat, unobstructed, and marshy. Full power was maintained on the right engine, and a left turn was initiated, apparently to return to the airport. Altitude was estimated at 400–500 feet during the turn. Airspeed dropped to 85–90 miles per hour, and the aircraft began to settle. The turning and settling continued until near ground level, where the aircraft was leveled laterally. It struck the ground in a level attitude, both laterally and longitudinally, and slid northeast for approximately 620 feet before striking large trees, turning about 180 degrees. Both the captain and copilot were thrown clear of the wreckage. The captain later died from injuries sustained.
Weather and Contributing Conditions
Weather conditions were good and not considered a factor. The accident investigation identified several issues. The aircraft was loaded above its maximum gross weight by an estimated 5,000 pounds. It had been flown beyond its 80-hour inspection period. Both engines were inadequately maintained, with defective ignition systems. The left engine malfunctioned, and its propeller was feathered shortly after takeoff at an airspeed of 130–135 miles per hour. The subsequent left turn led to a sharp airspeed drop to 85–90 miles per hour, and the aircraft settled to the ground in a near-stalled condition.
