What to do

Operators must perform repetitive inspections of the cabin lateral sliding plug door jettisoning mechanism as specified in the Airbus Helicopters Alert Service Bulletin AS332-52.00.56, starting within 110 flight hours or at the next jettisoning test after 22 February 2017. Any discrepancies found require immediate corrective action before the next flight. Additionally, the release system must be modified within 1,100 flight hours or 27 months from 10 April 2019, using the instructions in ASB AS332-52.00.59 or approved alternative service bulletins.

Summary

EASA Airworthiness Directive 2019-0064R1 is an updated safety directive addressing the emergency jettisoning mechanism of cabin lateral sliding plug doors on Airbus Helicopters AS 332 C, C1, L, and L1 models. It mandates inspections and modifications to prevent jamming of the door jettisoning system, which could obstruct emergency evacuation. This directive applies to helicopters equipped with specific door modifications and supersedes previous related directives.

What changed

EASA Airworthiness Directive 2019-0064R1 revises the original AD 2019-0064 by extending the compliance time for modifying the lateral plug door release system. It retains the requirement for repetitive inspections and corrective actions but allows a longer period before the mandatory modification must be completed. The AD also clarifies acceptable alternative modification methods.

Why it matters

This directive is critical for aviation professionals to ensure the emergency jettisoning system of cabin doors functions correctly, thereby safeguarding occupant evacuation during emergencies. Operators and maintenance organizations must comply to avoid unsafe conditions that could lead to door jamming. Compliance ensures continued airworthiness and regulatory adherence for affected Airbus Helicopters AS 332 variants.
