Airworthiness Directive · Amendment 39-21325 · Doors
Airbus Helicopters
This AD applies to all Airbus Helicopters Model EC130B4 helicopters, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model EC130B4 helicopters. This AD was prompted by reports of inflight detachment of the left-hand (LH) side cabin sliding doors and cases of impact damage on the main rotor blades, which were caused by degradation of the sliding door locking mechanism. This AD requires repetitive checks (measurements) of the load that operates the sliding door opening mechanism, repetitive inspections of the markings of the attachment screws for proper alignment, modifying the attachment system of the sliding door, and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2020-0069, dated March 24, 2020 (EASA AD 2020-0069).
(1) Where EASA AD 2020-0069 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2020-0069 refers to January 24, 2019 (the effective date of EASA AD 2020-0069), this AD requires using the effective date of this AD.
(3) The “Remarks” section of EASA AD 2020-0069 does not apply to this AD.
(4) The “Parts Installation” allowance provided in paragraph (8) of EASA AD 2020-0069 does not apply to this AD.
(5) Although the service information referenced in EASA AD 2020-0069 specifies to discard certain parts, this AD does not include that requirement.
