On June 13, 1994, about 1402 eastern daylight time, a Piper PA-28-140D, N888HA, registered to Huffman Aviation, Inc., collided with trees during takeoff from Morningstar Airport, Pine Land, Florida, while on a 14 CFR Part 91 personal flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The aircraft received substantial damage and the private-rated pilot received minor injuries. The passenger was not injured. The flight was originating at the time of the accident. The pilot stated the aircraft departed normally and climbed to about 100 feet, at which time it "began to loose lift." As the aircraft descended toward trees he turned toward a partial clearing. He then reduced engine power and flared into the small trees. The aircraft came to rest in a 45-degree nose-down attitude at the departure end of runway 27. The passenger stated they had landed to the east, turned around, and were taking off to the west when the accident occurred. They lifted off about half way down the runway. The aircraft began to climb and he remembered seeing 75 feet on the altimeter. Suddenly "it felt like the wind came out from under the wings." The aircraft began to descend. The engine did not quit and was struggling along. They hit a tree as they descended and the aircraft flipped nose down. After the aircraft came to rest he got out and helped the pilot out. He did not remember anything about the winds and stated that there were no thunderstorms in the area. The flight was departing on runway 27, a 2,100-foot grass strip. The winds which were reported at Page Field, Ft. Myers, Florida, 13 miles to the east of Morningstar Airport, were from 090 degrees at 6 knots. The Piper Aircraft flight manual for the PA-28-140D indicates the aircraft would need 2,300 feet takeoff distance to clear a 50-foot obstacle for the aircraft weight and density altitude conditions at the time of the accident. The chart did not take into account the use of a grass runway and departure with a tail wind.(See flight manual charts.)
