On March 18, 1995, about 1200 central standard time, a Cessna 150K, N6055G, registered to Southeast Aviation, operating as a 14 CFR Part 91 instructional flight, experienced a hard landing at the Bobby L. Chain Municipal Airport, Hattiesburg, Mississippi. Visual meteorological conditions prevailed and no flight plan was filed. The airplane sustained substantial damage. The student pilot was not injured. The flight originated about 35 minutes before the accident. The pilot stated he was making touch-and-go landings to runway 31. On his third landing he encountered a gust of wind, and the airplane became airborne. The nose dropped suddenly and the nosegear struck the runway. The airplane bounced back into the air in a tail low attitude, collided with the runway on the main landing gear, bounced, collided with the runway in a nose- down attitude, and collapsed the nosegear. Review of weather information obtained from the FAA, for the time period of the accident, revealed no recorded record of turbulence, downdrafts, gusts, or windshear. The accident was reported to the NTSB by Southeast Aviation on March 29, 1995.
