Flight Details
Air traffic control communications revealed that the pilot requested to take off from the departure runway to perform traffic pattern work and return for a landing on the left adjacent runway. Shortly after takeoff, while departing to the west, the pilot was instructed twice to enter the left traffic pattern but did not respond. Radar data showed the airplane departing the runway and remaining on the runway centerline heading for the duration of the flight. The airplane climbed to about 100 ft above ground level, and its groundspeed increased to 81 knots soon after departure then decreased to 70 knots before dropping off radar.
Witness Observations
Witnesses reported seeing the airplane depart the airport at a low climb rate and slow airspeed. Shortly after, the airplane flew out of view, and a column of smoke was observed on the horizon.
Accident Site Examination
Documentation of the accident site identified symmetrical propeller strikes on the ground, consistent with the airplane impacting the ground in a shallow, nose-up, wings-level attitude.
Engine and Airframe Examination
Examination of the airframe and both engines did not reveal any evidence of a preaccident mechanical failure or malfunction that would have precluded normal performance to allow for sufficient airspeed and climb rate after takeoff. Both engines exhibited damage signatures consistent with producing symmetrical power at impact.
Pilot Background
The pilot’s most recent flight in the accident airplane was 2 months before the accident. The pilot was reported to have had problems understanding the accident airplane’s avionics system; however, it is unknown if he was experiencing these problems during the accident flight. A review of the pilot’s medical history revealed no significant medical concerns or conditions that could pose a hazard to flight.
