Airworthiness Directive · Amendment 39-19562 · Landing gear
Airbus SAS Airplanes
Superseded. A later AD replaced this one: AD 2021-11-18. Comply with the one in force.
This AD applies to Airbus SAS airplanes, certificated in any category, all manufacturer serial numbers, identified in paragraphs (c)(1) through (c)(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.
We are superseding Airworthiness Directive (AD) 2017-07-05, 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 2017-07-05 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 retains the requirements of AD 2017-07-05 and removes the credit for doing an MLG overhaul in lieu of the initial inspection of the MLG leg components. This AD was prompted by further investigation after AD 2017-07-05 was issued, which revealed that overhaul of the MLG does not alleviate the need for inspecting the MLG hinge arm/barrel pin for cracking. We are issuing this AD to address the unsafe condition on these products.
For the purpose of this AD an affected part is an MLG hinge arm/barrel pin having part number (P/N) C66441-(X) and P/N C65543-(X), where the X is representing a variable number.
At the applicable compliance time specified in figure 1 to paragraph (h) of this AD, and thereafter at intervals not to exceed 100 flight cycles, accomplish a detailed visual inspection of the internal diameter of each affected MLG hinge arm/barrel pin for cracking, in accordance with the instructions of Airbus Alert Operators Transmission (AOT) A32W008-16, Rev 01, dated July 30, 2018 (“AOT A32W008-16, Rev 01”).
If any crack is found during any inspection required by paragraph (h) of this AD: Before further flight, replace the MLG leg in accordance with the instructions of Airbus AOT A32W008-16, Rev 01. Replacement of an MLG leg does not constitute terminating action for the repetitive inspections required by paragraph (h) of this AD.
At the applicable time specified in paragraph (j)(1) or (j)(2) of this AD, report the inspection results required by paragraph (h) of this AD to Airbus SAS. This can be accomplished using the instructions of Airbus AOT A32W008-16, Rev 01.
(1) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after each inspection required by paragraph (h) of this AD.
(2) 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.
