Airworthiness Directive · Amendment 39-21353 · Doors
Airbus Helicopters
This AD applies to Airbus Helicopters Model EC120B and EC130B4 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency (EASA) AD 2020-0095, dated April 29, 2020 (EASA AD 2020-0095).
The FAA is superseding Airworthiness Directive (AD) 2014-12- 12, which applied to certain Airbus Helicopters Model EC120B and EC130B4 helicopters. AD 2014-12-12 required inspecting and, if necessary, replacing parts of the sliding door star support attachment assembly. This AD requires modifying the sliding door star support stringer as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). This AD was prompted by several incidents involving helicopter left-hand side doors (both swinging and sliding) that revealed weaknesses in the locking mechanism. 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, EASA AD 2020-0095.
(1) Where EASA AD 2020-0095 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where paragraph (1) of EASA AD 2020-0095 specifies to complete the actions within 24 months after its effective date, this AD requires completion within 460 hours time-in-service after the effective date of this AD.
(3) The “Remarks” section of EASA AD 2020-0095 does not apply to this AD.
(4) Although the service information referenced in EASA AD 2020-0095 specifies to discard certain parts, this AD does not include that requirement.
(5) Where EASA AD 2020-0095 allows credit for Airbus Helicopters Alert Service Bulletin No. EC120-52A018, Revision 0, dated November 13, 2015 (ASB EC120-52A018 at original issue), this AD does not.
