Plain English Summary

2/10 complexity

This Airworthiness Directive requires owners/operators of Bell 430 helicopters (serials 49001–49106) to replace three servo-actuator-to-support attachment bolts and to insert revised Chapters 4 and 5 into the maintenance manual, following BHTC Alert Service Bulletin 430-05-33 (or a later Transport Canada–approved revision).

Compliance is within 150 flight hours after 27 October 2005 or by 31 December 2005; operators pay for and must carry out the specified replacement work. CASA issued the directive after the manufacturer set a 5,000-hour life limit for these bolts.
