FAA: Check Your Chopper's Fire Braids Before Flying

Published Date: 2/5/2025

Proposed Rule

Summary

If you own or operate Leonardo A109E, A109S, or AW109SP helicopters, listen up! The FAA wants you to check how the motor cables and fire extinguisher bonding braids are installed because some were put in wrong. Fixes might be needed to keep flying safe, and you’ve got until March 24, 2025, to share your thoughts on this plan—no big costs announced yet, just safety first!

Analyzed Economic Effects

2 provisions identified: 1 benefits, 1 costs, 0 mixed.

Reduces Engine Fire Extinguisher Risk

The proposed AD addresses incorrect installation of motor cables and bonding braids on Leonardo Model A109E, A109S, and AW109SP helicopters because improper installation could reduce the engine fire extinguishing system's performance and lead to loss of control of the helicopter. Requiring inspections and corrective action aims to detect and fix improper installations to lower the risk of extinguisher failure and subsequent accidents.

Inspection and Fix Mandate for A109 Series

If you own or operate Leonardo Model A109E, A109S, or AW109SP helicopters in the United States, the FAA proposes you must inspect the left- and right-hand motor (MTR) cables and the bonding braids connected to the engine fire extinguisher bottles and, if improperly installed, disconnect and properly reinstall them per EASA AD 2024-0193. The FAA estimates the inspection takes 1 work-hour at $85 per helicopter and would affect 101 U.S.-registered helicopters; disconnecting and reinstalling the MTR cable(s) and bonding braid(s) would take up to 1 work-hour and cost up to $85 per helicopter.
