Probable cause

The pilot's failure to maintain directional control during takeoff with a quartering tailwind. Contributing to the accident was the pilot's lack of experience in the accident airplane make and model.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The commercial pilot stated that, during the takeoff roll, the airplane swerved to the right, and he corrected to the left and aborted the takeoff; however, the airplane departed the left side of the runway and collided with an embankment. At the time of the accident, a quartering tailwind was present. The pilot had no previous experience in the accident airplane make and model or in any other multiengine airplane equipped with engines capable of producing 300 horsepower. During a postaccident conversation with a mechanic, the pilot stated that the airplane "got away from him" during the attempted takeoff. Because a postaccident examination of the airplane did not reveal any evidence of a preimpact mechanical malfunction or failure of the airplane's flight controls or nosewheel steering system that would have precluded normal operation and the pilot did not have any previous experience operating this make and model of airplane, it is likely that the pilot lost directional control during takeoff with a quartering tailwind.

Factual narrative

On August 19, 2017, about 1642 eastern daylight time, a Smith Aerostar 601P, N7108, was substantially damaged during takeoff from the Donegal Springs Airpark (N71), Marietta, Pennsylvania. The commercial pilot was not injured. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and no flight plan was filed for the local flight.According to the pilot he was hired by the owner of the airplane to reposition it from N71 to New Orleans, Louisiana. After completing a preflight inspection and engine run-up, he taxied the airplane to the active runway for takeoff. During the takeoff roll, the airplane swerved to the right and the pilot corrected to the left and aborted the takeoff; however, the airplane departed the left side of the runway and collided with an embankment. According to a mechanic, who was hired by the airplane owner to conduct a pre-purchase inspection of the airplane; the pilot was planning to deliver the airplane and had not previously flown the make and model of the accident airplane. He reviewed the operation of the airplane's systems with the pilot, including a specific discussion of the steering and braking systems, and then left the airport. The mechanic later received a call from the pilot who informed him about the accident and during a subsequent conversation the pilot stated that the airplane "got away from him." Examination of the airplane by a Federal Aviation administration (FAA) inspector revealed that the right wing was buckled, and the right main landing gear separated from the trunnion mount. Examination of the flight control system and the nose wheel steering system did not reveal any anomalies that would have precluded normal operation. During an interview with the FAA inspector, the pilot stated that he had never previously flown the accident airplane make and model, or any multiengine airplanes with engines capable of producing more than 300 horsepower each. The weather conditions reported at the Harrisburg International Airport (MDT), Harrisburg, Pennsylvania, which was located about 10 miles north of the accident site, included wind from 230° at 5 knots, visibility 10 statute miles, ceiling few at 6,000 ft, temperature 31° C, dew point 19° C, and an altimeter setting of 29.85 inches of mercury. At the time of the accident the airplane was departing with a quartering tail wind.
