Airworthiness Directives; Fokker Services B.V. Airplanes
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 airplanes. This proposed AD was prompted by reports that certain T-unions with an integral filter in the landing gear hydraulic control system disconnected from their housing and, in some cases, migrated. This proposed AD would require replacing certain T-unions with an integral filter with T-unions without an integral filter. We are proposing this AD to address the unsafe condition on these products.
Airworthiness Directives; Various Model 234 and Model CH-47D Helicopters
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.
