Airworthiness Directive · Amendment 39-19026 · Fuselage
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2020-22-11. Comply with the one in force.
This AD applies to Airbus Model A300 B4-603, A300 B4-620, A300 B4-622, A300 B4-605R, A300 B4-622R, A300 F4-605R, A300 F4-622R, and A300 C4-605R Variant F airplanes; certificated in any category; all manufacturer serial numbers.
We are superseding Airworthiness Directive (AD) 2004-23-20, which applied to certain Airbus Model A300, A300 B4-600, and A300 B4- 600R series airplanes; and Model A300 F4-605R and A300 C4-605R Variant F airplanes. AD 2004-23-20 required, for certain airplanes, repetitive inspections for cracking around certain attachment holes, installation of new fasteners for certain airplanes, and follow-on corrective actions if necessary. AD 2004-23-20 also required modifying certain fuselage frames, which terminated certain repetitive inspections. This new AD reduces certain compliance times, expands the applicability, and requires an additional repair on certain modified airplanes. This AD was prompted by a report indicating that the material used to manufacture the upper frame feet was changed and negatively affected the fatigue life of the frame feet. We are issuing this AD to address the unsafe condition on these products.
(1) Except for airplanes identified in table 2 to paragraphs (g)(1) and (g)(2) of this AD: At the times specified in table 1 to paragraph (g)(1) of this AD, depending on the average flight time (AFT), as defined in paragraph (i) of this AD, modify the upper frame feet fittings, including doing all applicable related investigative and corrective actions, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6125, Revision 04, dated March 17, 2015 (“SB A300-53-6125, Revision 04”). Do all applicable related investigative and corrective actions before further flight. Where Airbus SB A300-53-6125, Revision 04, 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 (l)(2) of this AD.
| Airplane usage | Initial compliance time (flight cycles or flight hours, whichever occurs first since first flight) |
|---|---|
| AFT greater than 1.5 | Within 10,200 flight cycles or 22,100 flight hours. |
| AFT equal to or less than 1.5 | Within 11,000 flight cycles or 16,600 flight hours. |
| Airplane configuration | Initial compliance time |
|---|---|
| Post-modification 12168 | Within 27,100 flight cycles or 47,300 flight hours since the airplane's first flight, whichever occurs first. |
| Post-SB A300-53-6125 | Within 27,100 flight cycles or 47,300 flight hours after embodiment of SB A300-53-6125, whichever occurs first. |
(2) For airplanes identified in table 2 to paragraphs (g)(1) and (g)(2) of this AD: At the applicable compliance time specified in table 2 to paragraphs (g)(1) and (g)(2) of this AD, modify the upper frame feet fittings, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6178, dated March 17, 2015. Where Airbus Service Bulletin A300-53-6178, dated March 17, 2015, specifies to contact Airbus for appropriate action, and specifies that action as “RC”: Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (l)(2) of this AD.
Prior to exceeding 24,100 total flight cycles or 42,000 total flight hours, whichever occurs first after doing the modification required by paragraph (g)(2) of this AD: Contact the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA); for instructions to do additional actions, and do those actions at the compliance times stated therein.
For the purpose of this AD, to establish the applicable AFT for the actions required by paragraph (g)(1) of this AD, divide the total accumulated flight hours counted from take-off to touch-down by the total accumulated flight cycles as of 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.
