This directive requires operators of Fokker F27 Mk 50 aircraft serials 20103–20258 to follow Fokker Service Bulletin F50-25-045: remove ageing tapered nylon shims under seat rails from fuselage STA.14025 aft and fit shorter seat‑rail attachment bolts to restore attachment strength. The Civil Aviation Safety Authority mandates compliance (by 1 Nov 1994); costs and downtime fall to owners/operators and their maintenance providers.
