What to do
Operators of Group 1 EC 175 B helicopters must inspect affected parts within 1760 flight hours or 24 months from 13 July 2023, whichever occurs first. If issues are found, replacement and adjustment of the jettison mechanism must be completed before further flight. All operators must follow enhanced maintenance procedures for each removal and operational check of the bad weather window and must not install affected parts after the effective date.
Summary
EASA Airworthiness Directive 2023-0129 is an airworthiness directive issued for Airbus Helicopters EC 175 B models. It addresses inspection requirements for cockpit door bad weather windows and emergency exit jettison mechanisms to ensure proper functionality. The directive applies to all serial numbers of EC 175 B helicopters with affected parts produced before 20 April 2023.
What changed
This new directive introduces a one-time inspection of affected cockpit door parts to verify conformity of the emergency exit mechanism, along with corrective actions if discrepancies are found. It also mandates enhanced periodic operational checks and prohibits installation of affected parts after the effective date. The directive is considered an interim action pending further measures.
Why it matters
This directive is critical for operators and maintenance organizations to prevent failure of the emergency escape system on EC 175 B helicopters. Ensuring the jettison mechanism functions correctly is vital for flight crew safety, especially in emergency situations such as water ditching. Compliance helps avoid potential life-threatening scenarios and regulatory penalties.
