Plain English Summary

3/10 complexity

This directive mandates repetitive inspections of the auto‑flight idle stop solenoid stroke on Fokker F50 aircraft (serials 20103–20192) that have incorporated Service Bulletin F50‑76‑008 Rev 1, using Fokker Service Bulletin F50‑76‑009. The first check is within 250 flight hours after SB incorporation and repeats every 250 hours.

It affects operators and their maintenance organisations (enforced under the Civil Aviation Safety Authority). Operators pay for inspections, downtime and any corrective work and must follow the referenced Fokker bulletin for technical procedures.
