Airworthiness Directive · Amendment 39-21851 · Lighting system
Leonardo S.p.a. Helicopters
This AD applies to Leonardo S.p.a. Model AW189 helicopters, certificated in any category, as identified in European Union Aviation Safety Agency AD 2021-0078, dated March 17, 2021 (EASA AD 2021-0078).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model AW189 helicopters. This AD was prompted by the determination that certain part-numbered fairings were never introduced into the main rotor (MR) tip lights kit design definition and were not certified for icing conditions. This AD requires replacing affected parts. This AD also prohibits, after modification of the helicopter as required, installing any affected part on any helicopter 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, EASA AD 2021-0078.
(1) Where EASA AD 2021-0078 refers to its effective date, this AD requires using the effective date of this AD.
(2) This AD does not mandate compliance with the “Remarks” section of EASA AD 2021-0078.
(3) Where EASA AD 2021-0078 refers to flight hours (FH), this AD requires using hours time-in-service (TIS).
(4) This AD does not mandate compliance with paragraph (1) of EASA AD 2021-0078.
(5) Where paragraph (4) of EASA AD 2021-0078 specifies that modification of a helicopter is a terminating action for the requirements of paragraph (1) of EASA AD 2021-0078, this AD does not provide a terminating action for the requirements of paragraph (1) of EASA AD 2021-0078 because this AD does not mandate compliance with paragraph (1) of EASA AD 2021-0078.
(6) Where paragraph (2) of EASA AD 2021-0078 specifies a compliance time of within 400 flight hours or 12 months, whichever occurs first, this AD requires compliance within 400 hours TIS after the effective date of this AD.
Although the service information referenced in EASA AD 2021-0078 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
