Recommendations aren’t mandatory. Introduction This Special Airworthiness Information Bulletin informs you of an airworthiness concern on all Sky Arrow 600 Sport airplanes, serial numbers (S/N) LSA001 to LSA021, that have been issued a special airworthiness certificate in the light-sport category (S-LSA). Background Sky Arrow 600 Sport S-LSA have been manufactured and granted airworthiness approval with a 3- point seat restraint system installatio n. This 3-point seat restraint system raises a concern for the safety of occupants during emergency landing conditions. This concern was specifically raised during investigation of an accident involving a Sky Arrow 600 Sport on October 7, 2008. ASTM International Standard Specification for Design and Performance of a Light Sport Airplane (i.e., ASTM F2245) specifies design requirements to protect each occupant during emergency landing conditions through seat belts or harnesses, or both. While there is no specific definition for what constitu tes an acceptable “seat belt” in the ASTM standard, the generally accepted description of seat belts for aircraft and automobiles includes a lap belt that provides pelvic restraint. FAA Technical Standard Order TSO-C22g for safety belts requires a safety belt restraint system that provides pelvic restraint. Also, 49 CFR § 571.209 defines a Type 1 seat belt assembly as having, “a lap belt for pelvic restraint” and a Type 2 seat belt assembly as having, “a combination of pelvic and upper torso restraints.” Despite this common interpretation of what constitutes an acceptable seat belt system for aircraft and automobiles, the Sky Arrow originally was delivered without a lap belt to provide pelvic restraint. After some consideration, the manufacturer of the Sky Arrow SLSA, Iniziative Industriali Italiane S.p.A. (3i) issued NOTIFICATION SA 3i LSA – 01/10, dated 03-September-2010, for optional replacement of the 3-point seat restraint system with a 5-point seat restraint system, which includes a lap belt. The S-LSA manufacturer 3i will also be installing the 5-point seat restraint system on all new Sky Arrow 600 Sport S-LSA beginning with S/N LSA022 and subsequent. These efforts reduce the potential exposure to this safety concern. However, there is some remaining concern for the Sky Arrow 600 serial numbers delivered with the original 3-point restraint system. Recommendations To enhance the protection of the occupants in the Sky Arrow 600 Sport S-LSA during em ergency landing conditions, the FAA recommends that the optional 5-point seat restraint system to include a lap belt be installed in the aircraft. This installation should be done in accordance with the manufacturer’s notification instructions. 2 For Further Information Contact Terry L.
