On August 3, 2007, at 1150 eastern daylight time, a Tecnam P92 Echo Super special light sport airplane (S-LSA), N107LS, was substantially damaged during landing at the Sebring Regional Airport (SEF), Sebring, Florida. The certificated flight instructor and certificated commercial pilot were not injured. Visual meteorological conditions prevailed for the local instructional flight conducted under 14 Code of Federal Regulations Part 91. According to both pilots, after landing on runway 18, the student pilot applied the brakes, and the left main landing gear collapsed. Examination of the airplane by a Federal Aviation Administration (FAA) inspector revealed substantial damage to the left wing, left stabilator, and fuselage. Further inspection of the landing gear revealed that one of the three bolts used to secure the landing gear strut to the fuselage was sheared. The airplane manufacturer issued a mandatory Service Bulletin, which required operators to check the landing gear bolts for damage, deformation and tightness. The Service Bulletin was issued on August 22, 2007 and required compliance within the next 10 hours. The winds reported at the closest airport, Okeechobee County Airport (OBE), Okeechobee, Florida, 29 nautical miles to the southeast, at 1125, were from 160 degrees at 4 knots.
