Plain English Summary

4/10 complexity

This directive requires operators of Eurocopter AS350 B/B1/B2/D helicopters to carry out the inspections and corrective actions in DGAC TAD T91-137-059(B) for the tail‑rotor pitch‑control lever expansion pin, to address a failure caused by incorrectly assembled bushes. Compliance is tied to the TAD’s revised effective date, 10 July 1991.

It affects owners/operators who bear inspection, parts and downtime costs, and is issued and enforced by CASA, which references the DGAC technical instructions (and Aerospatiale TSB 01‑33) for details.
