Northern Airmotive

The airplane was observed to depart normally for a positioning flight conducted during night visual meteorological conditions. In addition, the landing gear was observed to retract after takeoff. A witness who lived near the accident site heard a "loud" engine noise and observed the airplane just above the trees. The airplane then pitched down, impacted the ground, and exploded. The airplane impacted in a soybean field about a 1/2 mile from the departure end of the runway. Two pairs of ground scars were observed at the beginning of the debris path. The initial pair of ground scars were about 2 to 3 feet in length and were located about 380 feet south of the main wreckage. A pair of 10 to 12 foot long ground scars were located about 10 feet forward of the initial ground scars and they contained portions of the left and right engines; respectively. There was no impact damage observed to the portion of the soy bean field located in-between the second ground scar and the main wreckage. Prior to the flight, maintenance personnel replaced a frayed elevator trim cable. The work was supervised and checked by the accident pilot. Examination of the airplane did not reveal any evidence of a preimpact failure; however, a significant portion of the airplane was consumed in a post crash fire. Examination of the propellers revealed damage consistent with engine operation at the time of impact. The pilot reported 22,500 hours of total flight experience, with over 17,00 flight hours in make and model.

After takeoff at 600 feet, the right engine quit. The pilot said, '[the] altitude dropped about 100 feet and airspeed at 120 knots. The right engine came back again . . . It ran for about 10 seconds. [I] adjusted power on left engine . . . Feathered right prop and tried to maintain altitude, but airspeed kept diminishing, so I had to descend to maintain airspeed.' The pilot put the landing gear down to absorb the shock of landing in a field. An examination revealed no malfunctions in the engine or carburetor. The airplane was within allowable gross weight and center of gravity limits. The weather was: ceiling 600 feet broken, 1,500 feet overcast, visibility 3 miles, light rain and fog. The pilot escaped with minor injuries and the aircraft was damaged beyond repair.
