Airworthiness Directive · Amendment 39-22128 · Information systems
Various Transport Airplanes
This AD applies to the airplanes identified in EASA AD 2021-0234, dated October 28, 2021 (EASA AD 2021-0234), certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2019-20- 03, which applied to various transport airplanes. AD 2019-20-03 required modification of certain universal serial bus (USB) receptacles located in the flight deck. Since the FAA issued AD 2019-20-03, it has been determined that additional airplanes are affected by the unsafe condition. This AD continues to require the modification and expands the applicability, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD also prohibits the installation of affected parts. 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 2021-0234.
(1) Where EASA AD 2021-0234 refers to the effective date of December 14, 2018 (the effective date of the original issue of EASA AD 2018-0259) this AD requires using November 19, 2019 (the effective date of AD 2019-20-03).
(2) Where EASA AD 2021-0234 refers to its effective date, this AD requires using the effective date of this AD.
(3) The “Remarks” section of EASA AD 2021-0234 does not apply to this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
