Aircraft flight hours:
150
Circumstances:
The pilot was conducting the first leg of a positioning flight in an experimental, amateur built, tail-wheel turboprop airplane. During landing, the airplane touched down to the right of the runway centerline and departed the right side of the runway. The pilot then added engine power to attempt an aborted landing. The airplane lifted off the runway, pitched up at a steep angle, stalled, and impacted the ground. Examination of the wreckage did not reveal any mechanical malfunctions; however, a postcrash fire consumed the majority of the wreckage. The airplane's pitch trim actuator was observed in the landing position, which was the full nose-up position and would have resulted in a steep nose-up attitude during climb-out, if not corrected by the pilot. The pilot had accumulated about 1,930 hours of total flight experience; however, he only had 5 total hours in the same make and model as the accident airplane.
Probable cause:
The pilot's failure to retrim the airplane and maintain aircraft control during an aborted landing, which resulted in an inadvertent stall. Contributing to the accident was the pilot's lack of experience in the accident airplane make and model.

Circumstances:
According to the pilot, he requested the refueler to top off his fuel tanks with "100 low lead fuel". After refueling, the pilot performed a preflight including taking fuel samples from under the wings, draining the rear fuel drain, and checking the fuel cap for security. The engine start, run-up, and taxi were uneventful. The airplane departed runway 17 and was in a positive rate of climb. At approximately 200 feet AGL the airplane began to lose power. Shortly after the pilot ensured that the throttle, propeller, and mixture controls were in the full forward position, the airplane lost power in both engines. The pilot executed an emergency off field landing. Examination of the wreckage revealed that the left wing had broken off and the aft cabin area was crushed. According to the refueler, he stated that he mistakenly used the Jet-A fuel truck instead of the AVGAS 100 low lead truck, and pumped 58 gallons of Jet-A into the airplane. Examination of the fuel samples taken from both engines revealed the left and right engine contained 70 percent of jet A fuel.
Probable cause:
The improper refueling of the airplane by airport personnel with the incorrect fuel grade that resulted in a total loss in engine power on both engines during initial climb. A factor was the inadequate preflight inspection by the pilot in command.

Aircraft flight hours:
6317
Circumstances:
The flight was in cruise flight at 27,000 feet when the airplane encountered unforecasted severe turbulence. The pilot made a "mayday" on the airplane radio to Jacksonville Center. Within several seconds the airplane accelerated from 175 knots through 300 knots ground speed and descended from 27,000 feet to 16,500 feet. The airplane disappeared from radar coverage and was located by Sheriff Department personnel 15 miles north of Homerville, Georgia, in a swampy area. Airframe components recovered from the accident site were submitted to the NTSB Materials laboratory for examination. The examinations revealed all failures were due to overload. Examination of the airframe revealed that the airframe design limits were exceeded. The pilot did not obtain a weather briefing before the flight departed.
Probable cause:
An in-flight encounter with unforecasted severe turbulence in cruise flight resulting in the design limits of the airplane being exceeded due to an overload failure of the airframe, and collision with a swampy area.
