可靠性信息在直11型机功能-可靠性适航审定中的应用

在直11型机的适航审定时，按CCAR25．15(二)的要求，要进行功能-可靠性飞行试验，以验证该机是否满足CCAR27．1301(d)和CCAR27．1309(a)的要求。本文基于直11型机外场收集的可靠性信息，论述了该机的功能-可靠性与条例要求的相符性，从而把CCAR21所要求的功能-可靠性飞行验证时间减少为38小时，显然，这将减少飞行试验时间，加快试验进度，为今后用可靠性信息来验证新研直升机的功能-可靠性与适航条例要求相符性提供了合适的方法。

APPLICATION OF THE RELIABILITY INFORMATION IN THE AIRWORTHINESS CERTIFICATION OF THE FUUCTION-RELIABILITY FOR Z11 HELICOPTER

During the airworthiness certification of the Zll helicopter, It must complete a flight test of the function-reliability to demonstrate the compliance with CCAR27.1301(d) and CCAR27.1300(a) according to CCAR25.15(2).Based on the reliability information in the field of the Z11 helicopter, this paper describes compliance of the function-reliability with airworthiness equipment. The application of the reliability information decreases flight time require by CCAR21 to 38 flight hours. Obvious,it decreases flight-test time,promote program processes and provides effective method to demonstrate compliance of the function-reliability with the airworthiness requirement for new helicopters.
