Summary
We are adopting a new airworthiness directive (AD) for various Model 234 and Model CH-47D helicopters. This AD requires inspections of the pitch housing and revising the pitch housing retirement life. This AD was prompted by reports of cracking in the pitch housing lugs. The actions of this AD are intended to detect and prevent an unsafe condition on these products.
