摘　　要：The part 23 airworthiness standards for small airplanes states minimal standards of the emergency condition for the occupant protection. Under this regulation, the airplane must be designed and certified about static strength of the fuselage and seats, horizontal and vertical dynamic strength of seats. Human injuries in dynamic crash tests and the survivability in the turnover condition should be also evaluated. The most important part among injuries of human is a head and the head injury is evaluated by Head Injury Criterion （HIC）. KC-100, 4 seats airplane that is manufactured by KAI, was conducted seat dynamic tests. The HIC from tests was well within criteria limits 1,000 and the occupant compartment for head protection provided hazard-free spaces in the occupant＇s head strike envelope for the frontal-horizontal crash impacts. The airplane also was conducted a turnover static test and analysis to especially show living spaces of the head. The airframe could sustain living spaces for occupants in the turnover condition and occupants could escape and be protected. The results of tests and analysis corresponded to the criteria and proved the retention of survivable space in emergency landing condition.
