Plain English Summary

2/10 complexity

What this requires:

This directive mandates safety inspections of the rudder trim tabs (small adjustable surfaces on the aircraft's tail that help maintain straight flight) on Fokker F27 aircraft.

Who must comply:

Operators of any Fokker F27 model where the rudder trim tab has accumulated more than 1,000 hours of "time in service" (flight time)
Unless the aircraft has already been modified according to Fokker Service Bulletin B-169 (a manufacturer-issued technical instruction)

What must be done: Operators must conduct inspections following the procedures detailed in Fokker Service Bulletin B-165, Issue 3.

How often: These inspections must be performed every 200 flight hours (or more frequently).

Why it matters: Worn or cracked rudder trim tabs can compromise aircraft control. This rule ensures potential failures are detected before they become dangerous.
