Summary
EASA Airworthiness Directive Cancellation Notice 2026-0126-CN is an official cancellation of the previous DGCA AD 2003-084(B) R1 concerning fire protection safe selector switches with metallic snap wire on Dassault Aviation Mystère-Falcon 900 and Falcon 2000 aeroplanes. This cancellation confirms that no unsafe conditions related to metallic lock wires on fire extinguisher control switches have been reported since the original directive. The notice applies to all serial numbers of the affected aircraft models.
What Changed
This document cancels the earlier DGCA AD 2003-084(B) R1, which required updates to the aeroplane maintenance manual and inspections related to metallic lock wires on fire extinguisher control switches. The cancellation reflects Dassault's confirmation that no incidents involving metallic lock wires have occurred, and the existing maintenance procedures remain sufficient. No new actions or inspections are mandated by this cancellation notice.
Why It Matters
For aviation professionals, this cancellation removes the requirement to perform one-time inspections and updates related to metallic lock wires on fire extinguisher control switches for the specified Dassault aircraft. Operators and maintenance organizations can rely on the current maintenance manual procedures without additional compliance burdens. This reduces administrative and operational overhead while maintaining safety standards.
What To Do
Affected operators and maintenance teams do not need to take any further action regarding the metallic lock wire issue as mandated by the cancelled DGCA AD 2003-084(B) R1. They should continue to follow the existing maintenance manual tasks for fire extinguisher control switches as part of regular C checks. No new compliance deadlines are introduced by this cancellation notice.
