Airworthiness Directive · Amendment 39-21580 · Landing gear
Airbus SAS Airplanes
This AD applies to all Airbus SAS airplanes, certificated in any category, identified in paragraphs (c)(1) through (5) of this AD.
(1) Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes.
(2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(3) Model A300 B4-605R and B4-622R airplanes.
(4) Model A300 F4-605R and F4-622R airplanes.
(5) Model A300 C4-605R Variant F airplanes.
The FAA is superseding Airworthiness Directive (AD) 2019-03- 10, which applied to all Airbus SAS Model A300 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300-600 series airplanes). AD 2019-03-10 required repetitive detailed visual inspections of the main landing gear (MLG) leg components and replacement of the MLG leg if cracked components are found. This AD continues to require the actions required by AD 2019-03-10. For certain airplanes, this AD also requires modification of the MLG hinge arm by installing improved MLG hinge arm/barrel pins; an out-of-roundness check of removed pins; repetitive inspections of any affected pins and the associated connecting rod bushes, and replacement of the MLG leg if cracked components are found; and installation of an improved spacer; as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. This AD was prompted by reports of cracks in MLG leg components and a determination that additional actions (including inspections, modifications, and checks) are needed to address the unsafe condition. 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 2020-0145, dated July 1, 2020 (EASA AD 2020-0145).
(1) Where EASA AD 2020-0145 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2020-0145 refers to the effective date of EASA AD 2018-0170, this AD requires using March 29, 2019 (the effective date of AD 2019-03-10).
(3) The “Remarks” section of EASA AD 2020-0145 does not apply to this AD.
(4) Paragraph (3) of EASA AD 2020-0145 specifies to “send all removed pins for an out-of-roundness check.” For this AD, do an inspection of each pin for out-of-roundness, in accordance with Safran Service Bulletin 470-32-840, dated December 3, 2019.
(5) Paragraph (3) of EASA AD 2020-0145 specifies to report inspection results to Safran within a certain compliance time. For this AD, report inspection results at the applicable time specified in paragraph (h)(5)(i) or (ii) of this AD.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of 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.
