FAA Orders Airbus Chopper Manual Tweaks: Yawn-Worthy Safety Update

Published Date: 8/13/2026

Rule

Summary

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC 155 B and EC 155 B1 helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable. The FAA is issuing this AD to address the unsafe condition on these products.

Analyzed Economic Effects

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

New limits to prevent structural failures

The AD requires adoption of new or more restrictive airworthiness limitations to prevent failure of certain parts and primary structural components that could lead to loss of control of the helicopter. The AD incorporates EASA AD 2025-0191 procedures for replacing components before life limits are exceeded and for completing maintenance tasks within specified thresholds and intervals.

Must revise maintenance limits in 30 days

If you operate an Airbus Helicopters Model EC 155 B or EC 155 B1, you must revise the airworthiness limitations section (ALS) of the maintenance manual or instructions for continued airworthiness and the approved maintenance/inspection program within 30 days after the AD’s effective date of September 17, 2026. The FAA estimates this affects 16 U.S.-registered helicopters and that the one-time work is about 1 work-hour at $85 ($85 per helicopter), totaling $1,360 for U.S. operators.
