Airworthiness Directive · Amendment 39-19002 · Wings
Airbus Airplanes
This AD applies to Airbus Model A310-203, -221, -222, -304, -322, -324, and -325 airplanes, certificated in any category, all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A310-203, -221, -222, -304, -322, -324, and -325 airplanes. This AD was prompted by an evaluation by the design approval holder indicating that the wing bottom skin at the main landing gear (MLG) reinforcing plate is subject to widespread fatigue damage (WFD). This AD requires a modification of the wing bottom skin at the MLG reinforcing plate. We are issuing this AD to address the unsafe condition on these products.
Within the compliance times defined in table 1 to paragraph (g) of this AD, table 2 to paragraph (g) of this AD, or table 3 to paragraph (g) of this AD, as applicable to airplane type and utilization: Do a modification of the left-hand and right-hand wing bottom skin at the MLG reinforcing plate, including all related investigative actions and applicable corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-57-2104, dated December 15, 2015, except as required by paragraph (h) of this AD. Do all related investigative and applicable corrective actions before further flight. For the purpose of this AD, the term “short range” applies to airplanes with an average flight time (AFT) lower than 1.5 flight hours per flight cycle, and the term “long range” applies to airplanes with an average flight time equal to or higher than 1.5 flight hours per flight cycle. For determining the “short range” and “long range” airplanes, the AFT is the total accumulated flight hours, counted from take-off to touch-down, divided by the total accumulated flight cycles at the effective date of this AD.
| Compliance time (whichever occurs later, A or B) |
|---|
| A Before exceeding 28,800 flight cycles (FC) or 57,600 flight hours (FH), whichever occurs first since first flight of the airplane. |
| B Within 960 FC, or 1,920 FH, or 12 months, whichever occurs first after the effective date of this AD. |
| Compliance time (whichever occurs later, A or B) |
|---|
| A Before exceeding 27,700 FC or 77,700 FH, whichever occurs first since first flight of the airplane. |
| B Within 920 FC, or 2,580 FH, or 12 months, whichever occurs first after the effective date of this AD. |
| Compliance time (whichever occurs later, A or B) |
|---|
| A Before exceeding 20,500 FC or 102,500 FH, whichever occurs first since first flight of the airplane. |
| B Within 680 FC, or 3,420 FH, or 12 months, whichever occurs first after the effective date of this AD. |
Where Airbus Service Bulletin A310-57-2104, dated December 15, 2015, specifies to contact Airbus for appropriate action, and specifies that action as “RC” (Required for Compliance): Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (i)(2) of this AD.
