What to do

Operators must modify the window jettisoning system within specified compliance times based on operational conditions—110 flight hours for helicopters operated over water and 250 flight hours for those not operated over water, or within six months from the effective date, whichever occurs first. After modification, affected helicopters are no longer subject to the requirements of the previous AD 2018-0039.

Summary

EASA Airworthiness Directive 2019-0107 is an airworthiness directive issued by the European Union Aviation Safety Agency affecting Airbus Helicopters AS 332 L2 and EC 225 LP models. The directive addresses issues with the window jettisoning system on specific serial numbers of these helicopters to ensure safe evacuation during emergencies.

What changed

This directive requires modification of the window jettisoning system by removing the polytetrafluoroethylene (PTFE) skived film and installing silicone seals on the helicopter cabin windows. It supersedes previous temporary measures and mandates compliance through Airbus Helicopters Alert Service Bulletins.

Why it matters

The directive is critical for aviation professionals as it addresses a safety risk where excessive friction could prevent window jettisoning, potentially hindering emergency evacuation. Operators and maintenance teams must ensure compliance to maintain airworthiness and passenger safety.
