Airworthiness Directive · Amendment 39-15291 · Fuselage
Airbus Model A310 Series Airplanes
This AD applies to Airbus Model A310 series airplanes, certificated in any category; all certified models; all serial numbers; except airplanes that have received in-service application of Airbus Service Bulletin A310-53-2125.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions: Reinforce the fuselage butt joint at FR 55/58 in accordance with the Accomplishment Instructions of Airbus Service Bulletin A310-53-2125, including Appendix 01, dated January 9, 2007, at the applicable compliance times listed in Table 1 (threshold) or Table 2 (grace period) of this AD, whichever occurs later.
| Whichever occurs first after the effective date of this AD | Accumulated time since first flight (in flight cycles) | Accumulated time since first flight (in flight hours) |
|---|---|---|
| A310-200 airplanes | 41,500 | 83,500 |
| A310-300 airplanes with an average flight time (AFT) ≤ to 4 hours | 33,000 | 93,500 |
| A310-300 airplanes with an AFT > 4 hours | 20,500 | 102,000 |
| Whichever occurs first after the effective date of this AD | Flight cycles | Flight hours |
|---|---|---|
| A310-200 airplanes | 1,500 | 3,000 |
| A310-300 airplanes with an AFT ≤ 4 hours | 1,200 | 3,400 |
| A310-300 airplanes with an AFT > 4 hours | 740 | 3,600 |
