Plain English Summary

2/10 complexity

This safety rule applies to all models of Eurocopter AS 355 (Twin Ecureuil) helicopters.

What it requires:

Aircraft operators must perform a one-time inspection of the engine firewalls (the protective barriers between the engine and passenger areas) following the manufacturer's technical instructions (called Service Bulletin 71-04).
This inspection must be completed before the aircraft can receive its official safety certificate (Certificate of Airworthiness).

Why it matters: This update combines several older safety rules into one document to reduce paperwork for operators. It keeps the firewall inspection requirement but removes other technical instructions—specifically, operators no longer need to follow Service Bulletin 71-08 under this rule, and requirements from Service Bulletin 05-02 have been moved to a separate safety directive (AD/AS 355/36).
