Airworthiness Directive · Amendment 39-21463 · Powerplant
Airbus SAS Airplanes
This AD applies to all the Airbus SAS airplanes identified in paragraphs (c)(1) through (4) of this AD, certificated in any category.
(1) Model A318-111 and -112 airplanes.
(2) Model A319-111, -112, -113, -114, and -115 airplanes.
(3) Model A320-211, -212, -214, and -216 airplanes.
(4) Model A321-111, -112, -211, -212, and -213 airplanes.
The FAA is superseding Airworthiness Directive (AD) 2018-16- 02, which applied to all Airbus SAS Model A318-111 and -112 airplanes; Model A319-111, -112, -113, -114, and -115 airplanes; Model A320-211, - 212, -214, and -216 airplanes; and Model A321-111, -112, -211, -212, and -213 airplanes. AD 2018-16-02 required modifying and re-identifying the 3-lug aft engine mount assemblies. This AD continues to require modifying and re-identifying the 3-lug aft engine mount assemblies, and also requires modifying and re-identifying the 4-lug aft engine mount assemblies; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. The FAA is issuing this AD to address the unsafe condition on these products.
For the purposes of this AD, the production quality deficiency is defined as a “dull” finish, which is caused by surface finish pitting, and is an aggravating factor to crack initiation from vibration dynamic effect when compared with the “bright” surface finish.
Except as specified in paragraph (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, paragraphs (3) through (6), (8), (9), (11), and (12) of European Union Aviation Safety Agency (EASA) AD 2020-0085, dated April 6, 2020 (EASA AD 2020-0085).
(1) Where EASA AD 2020-0085 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2020-0085 refers to August 16, 2017 (the effective date of EASA AD 2017-0138, dated August 2, 2017), this AD requires using September 13, 2018 (the effective date of AD 2018-16-02).
(3) Where EASA AD 2020-0085 refers to December 15, 2017 (the issue date of EASA AD 2017-0251), this AD requires using September 13, 2018 (the effective date of AD 2018-16-02).
(4) The “Remarks” section of EASA AD 2020-0085 does not apply to this AD.
(5) Where paragraph (8) of EASA AD 2020-0085 specifies “do not operate any airplane having installed a, and do not install on any airplane a `dull' finish aft engine mount inner retainer,” for this AD, do not operate any airplane having installed any inner retainers affected by the production quality deficiency (as defined in paragraph (g) of this AD), and do not install on any airplane a `dull' finish aft engine mount inner retainer.
(6) Where paragraph (9.3) of EASA AD 2020-0085 refers to January 27, 2016 (the effective date of EASA AD 2016-0010, dated January 13, 2016), this AD requires using April 3, 2017 (the effective date of AD 2017-04-10).
(7) Where paragraph (12) of EASA AD 2020-0085 specifies a compliance time of “before next flight after December 15, 2017,” for this AD, that compliance time is “within 30 days after September 13, 2018” (the effective date of AD 2018-16-02.)
(1) Modification of an airplane as required by paragraph (h) of this AD (i.e., accomplishing the modification required by paragraph (3) of EASA AD 2020-0085, the replacement specified in paragraph (4) of EASA AD 2020-0085, or the modification specified in paragraph (5) of EASA AD 2020-0085), constitutes terminating action for the repetitive detailed inspections required by paragraph (l) of AD 2016-14-09 for that airplane.
(2) Modification of an airplane as required by paragraph (h) of this AD (i.e., accomplishing the modification required by paragraph (3) of EASA AD 2020-0085, the replacement specified in paragraph (4) of EASA AD 2020-0085, or the modification specified in paragraph (5) of EASA AD 2020-0085), is a method of compliance with the requirements of paragraph (g) of AD 2017-04-10 for that airplane.
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.
