Plain English Summary

2/10 complexity

This safety directive requires a specific modification to be made to certain aircraft engine starters before they can legally be installed in any aircraft.

Who it affects:

Aircraft mechanics and maintenance organisations
Owners of aircraft fitted with BTH type Z1-2 Impulse Starters that have part number CX55288

What you must do: If you have one of these starters, you cannot install it in an aircraft until it has been modified using either:

De Havilland Modification G2242 (Part 3), or
Airworthiness Notice 107.2.16.2.4

Why it matters: These starters have a mechanical component (called a "pawl") that likely has a safety defect. The referenced documents contain the technical instructions to fix the issue and prevent potential engine starting failures or damage.
