NTSB Identification: GAA17CA020
14 CFR Part 91: General Aviation
Accident occurred Tuesday, October 11, 2016 in Lowell, AR
Probable Cause Approval Date: 07/05/2017
Aircraft: REMOS AIRCRAFT GMBH REMOS GX, registration: N27GX
Injuries: 2 Uninjured.
NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
According to the pilot, he performed three off-airport, soft-field landings and was landing in a southerly direction. He added that, after the third landing, he turned the aircraft around and took off to the north, “because of all the tall trees on the south end of the strip.” He remarked that the wind was calm on the ground but that, during his takeoff climb, he encountered “wind shear and my airspeed dropped from 50 kts to 30 kts.” He recalled that the airplane struck a tree, descended, and impacted terrain.
According to the nearest METAR from an aerodrome located about 3 miles northeast of the accident site, the wind about the time of the accident was from 210° at 13 kts. The METAR indicated that the prevailing wind throughout the day was a southerly wind.
According to the Pilot’s Handbook of Aeronautical Knowledge, “Takeoff Performance,” pages 10-14, paragraph 5:
The effect of wind on takeoff distance is large, and proper consideration also must be provided when predicting takeoff distance. The effect of a headwind is to allow the aircraft to reach the lift-off speed at a lower groundspeed while the effect of a tailwind is to require the aircraft to achieve a greater groundspeed to attain the lift-off speed.
A headwind that is 10 percent of the takeoff airspeed will reduce the takeoff distance approximately 19 percent. However, a tailwind that is 10 percent of the takeoff airspeed will increase the takeoff distance approximately 21 percent.
The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s decision to take off with a prevailing tailwind and insufficient distance to ensure obstacle clearance, which resulted in a collision with a tree.
