Plain English Summary

2/10 complexity

Owners/operators of seven specific Fokker F100 (F28 Mk 100) airframes (listed serial numbers) must inspect the vertical stabiliser and install three reinforcement doublers per Fokker Service Bulletin F100-55-011. Work must be done, if not already, before the aircraft reaches 6,500 flight cycles.

The directive mandates operator-funded parts, labour and downtime to address fatigue cracks found in the stabiliser skin and underlying structure, aiming to extend fatigue life.

through 11273.

Requirement: Inspect the vertical stabiliser and install three reinforcement doublers in accordance with Fokker Service Bulletin (SB) F100-55-011 dated 1 October 1991.

Compliance: Unless previously accomplished, before accumulating 6,500 flight cycles since new.

This Airworthiness Directive becomes effective on 22 April 1999.

Background: Fatigue tests on the F.28 Mk.0100 have revealed cracks in the skin of the vertical stabiliser at rib 5.0 near intermediate spars I and II, and in the underlying structure. This AD requires a modification to prevent cracks and to improve the fatigue life of the vertical stabiliser.
