FAA Proposes Inspection for Airbus Helicopters Engine Flange
/ 1 min read
Table of Contents
The Federal Aviation Administration is proposing a new safety rule for certain Airbus helicopters. The agency wants to require a one-time inspection of the main engine coupling on specific models. This comes after European regulators found that some helicopters built recently may have had an engine flange installed backward during manufacturing.
Why it matters: This rule exists because a manufacturing error on the assembly line created a specific mechanical risk. For helicopter owners and operators, the practical effect is a mandatory check and potential replacement part during their next maintenance window. If finalized, it will become a legal requirement under FAA safety regulations. Until then, it is just a proposal open to public feedback.
Who it affects
- Owners and operators of specific Airbus Helicopters models (AS 350 B, BA, B1, B2, B3, AS 350 D, and EC 130 B4 and T2) built before May 2023 or February 2023
The Federal Aviation Administration published this proposed rule in the Federal Register under Docket No. FAA-2026-4638; you should review the full text and comment instructions at regulations.gov before relying on this summary.
