Plain English Summary

2/10 complexity

This AD mandates reinforcement of the elevator trim cable pulley brackets and mountings on specified Fokker F50 (F27 Mk 50) aircraft (serials 20103–20108, 20110–20123) per Fokker Service Bulletin F50‑27‑008, to be done before each affected aeroplane reaches 8,000 flight cycles. It implements an engineering fix for reduced fatigue life from increased cable tension, imposing tracking, downtime and modification costs on the listed owners/operators.

AD/F50/22 Elevator Trim Cable Pulley Bracket and Mounting 8/89

Applicability: Serial numbers 20103 through 20108 and 20110 through 20123.

Requirement: Reinforce elevator trim cable pulley brackets and mountings in accordance with Fokker Service Bulletin F50-27-008 dated 3 February 1989.

Note: Netherlands AD 89-24 refers.

Compliance: Prior to the accumulation of 8000 flight cycles.

Background: Stress analysis has shown that the increased tension in the elevator trim cables will decrease the fatigue life of the pulley brackets and mountings.
