NTSB Identification: ERA13LA264
14 CFR Part 91: General Aviation
Accident occurred Saturday, June 01, 2013 in Williamson, SC
Probable Cause Approval Date: 06/02/2014
Aircraft: GLOBE GC-1B, registration: N3715K
Injuries: 2 Serious.
NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot performed a preflight inspection and engine run up with no anomalies noted. He noted the wind favored runway 10. He then taxied to the 2,400-ft turf runway, which had 50-ft tall trees located 1,000 ft from the departure end, and began the takeoff. When the airplane reached climb speed, the pilot lifted the airplane off the runway. He then realized that the airplane was not going to be able to climb above the trees located near the end of the runway. Therefore, the pilot decided to perform a precautionary landing in a nearby field. During the landing roll, the airplane struck a tree and incurred substantial damage. The pilot and pilot-rated passenger, who were both airframe and powerplant mechanics, reported no preimpact mechanical malfunctions with the airplane that would have precluded normal operation.The wind reported at an airport 10 miles north of the accident location and at other surrounding airports was such that the airplane would have experienced a 5- to 8-knot right-quartering tailwind on runway 10 around the time of the accident. Density altitude was 2,307 feet above mean sea level. It is therefore likely, that the airplane experienced a reduction in performance during takeoff due to the tailwind, density altitude, and the weight (within about 120 lbs of the maximum gross weight) at which the airplane was being operated.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot’s decision to takeoff with a quartering tailwind at high density altitude, close to gross takeoff weight, on a short turf runway with trees at the departure end.
