Pilots have been recognized as an occupational group having very high work-related death rates. Commuter aircraft and air taxis are far more likely to be involved in fatal crashes than are larger airplanes. To examine the factors related to pilot survival in commuter aircraft and air taxi crashes, we analyzed National Transportation Safety Board data for the years 1983 to 1988. Case fatality rates were calculated for the pilots-in-command and odds ratios were estimated from a multivariate logistic regression model for variables related to pilots, aircraft, and circumstances. During the 6-year period, 536 people were killed and 744 injured in 888 commuter aircraft and air taxi crashes. The pilot case fatality rate was 20%. The most important determinants of pilot fatality were postcrash fire (odds ratio [OR] 8.2), off-airport location (OR 8.1), bad weather (OR 4.3), and nonuse of shoulder restraints (OR 3.7); all were significant at P < .01. Crash survival could be enhanced by more crashworthy fuel systems, aircraft seats, and use of restraint systems in commuter aircraft and air taxis. The value of shoulder restraints for pilots in these aircraft is confirmed and their use should be vigorously promoted.
飞行员被认为是一个与工作相关死亡率极高的职业群体。通勤飞机和空中出租车比大型飞机更有可能卷入致命坠机事故。为了研究与通勤飞机和空中出租车坠机事故中飞行员生存相关的因素,我们分析了美国国家运输安全委员会1983年至1988年的数据。计算了机长的病死率,并从多变量逻辑回归模型中估计了与飞行员、飞机和事故情况相关变量的比值比。在这6年期间,888起通勤飞机和空中出租车坠机事故中有536人死亡,744人受伤。飞行员病死率为20%。飞行员死亡的最重要决定因素是坠机后起火(比值比[OR]8.2)、机场外位置(OR 8.1)、恶劣天气(OR 4.3)和未使用肩部安全带(OR 3.7);所有这些在P <.01时均具有显著性。通勤飞机和空中出租车采用更具防撞性的燃油系统、飞机座椅以及使用约束系统可以提高坠机生存率。这些飞机上肩部安全带对飞行员的价值得到了证实,应大力推广其使用。
