AD/AS 355/17 - Securaiglon (Ex Laiglon) Safety Belts - Modification - CANCELLED

This Airworthiness Directive (AD) cancels a previous safety rule for specific helicopters.

What it does

• Revokes a requirement for owners of Eurocopter AS 355 (Twin Ecureuil) helicopters to modify passenger seat belts made by Securaiglon (formerly Laiglon).
• The original rule (dating back to before 1985) required these modifications to ensure safety.
• As of 30 July 2009, operators no longer need to comply with this modification requirement; the rule is completely cancelled.

Who it affects

• Owners and operators of Eurocopter AS 355 series helicopters that were subject to the original seat belt modification order.

Why it matters

• Removes an outdated regulatory burden. The safety modification is no longer considered necessary, simplifying maintenance obligations for affected aircraft.
