Airworthiness Directive 2018-24-05
one-timeAirworthiness Directives; Fokker Services B.V. Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 airplanes. This AD was prompted by reports that filters, which are integral to certain T-unions in the landing gear hydraulic control system, disconnected from their housing and, in some cases, migrated. This AD requires replacing certain T- unions with an integral filter with T-unions without an integral filter. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2018-24-05 applies to
Applies to all manufacturer serial numbers.
Whether AD 2018-24-05 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
