What to do
Operators of affected AS 332 and EC 225 helicopters must modify the windows jettisoning system within specified compliance times based on helicopter group and operation over water. For Group 3 helicopters, modification must be done within 25 months or can be deferred with mandatory repetitive inspections every 100 flight hours or 12 months. Damaged window seals found during inspections must be replaced before further flight.
Summary
EASA Airworthiness Directive 2021-0012R1 is a regulatory update addressing the windows jettisoning system modification for Airbus Helicopters AS 332 and EC 225 models. It applies to various AS 332 variants and EC 225 LP helicopters, focusing on preventing difficulties in jettisoning windows during emergencies. The directive mandates modifications to the window jettisoning system to ensure safe evacuation.
What changed
This revision of EASA AD 2021-0012 adds an alternative compliance method for Group 3 helicopters, allowing an extension of the modification compliance time if repetitive inspections of window seals are performed. It retains previous requirements for Groups 1 and 2 and expands applicability to more helicopter models. The AD supersedes earlier directives related to this unsafe condition.
Why it matters
This directive is critical for aviation professionals because it addresses a safety issue that could hinder emergency evacuation by preventing window jettisoning. Operators and maintenance teams must ensure compliance to avoid operational restrictions and maintain airworthiness. The alternative compliance option provides flexibility while maintaining safety through inspections.
