AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators must modify and reidentify the affected fuse covers according to the latest Airbus Helicopters Alert Service Bulletins within 660 flight hours or 9 months from 26 March 2026, whichever occurs first. After modification, installation of pre-modification affected parts is prohibited. Stakeholders should consult the specified ASBs for detailed instructions and may seek alternative compliance methods if approved by EASA.
Summary
EASA Airworthiness Directive 2026-0052R2 is a regulatory document addressing a safety issue in Airbus Helicopters AS 350 B2, AS 350 B3, and EC 130 B4 models. The directive mandates modification and reidentification of specific fuse covers on the circuit breaker panel to prevent interference with the pilot pedal, which could reduce yaw control. It applies to helicopters with certain modifications embodied and affected fuse cover part numbers.
What changed
This revision updates the original AD 2026-0052 and its first revision by incorporating amended modification instructions for AS 350 helicopters and extending the compliance time for both AS 350 and EC 130 B4 helicopters. It also revises the definition of the applicable Alert Service Bulletins and includes editorial improvements to meet current EASA standards.
Why it matters
The directive addresses a critical safety concern where a partially detached fuse cover could block pilot pedal movement, potentially compromising helicopter yaw control. Compliance ensures continued airworthiness and operational safety, preventing incidents related to pedal interference. Operators and maintenance organizations must adhere to these updated requirements to avoid regulatory non-compliance and maintain safe flight operations.
