Airworthiness Directive · Amendment 39-14198 · Airbus Model A300 B2 and B4 Series Airplanes; Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
Airbus Model A300 B2 and B4 Series Airplanes; Model A300 B4-600, B4-600R, and F4-600R Series Airplanes, and Model A300 C4-605R Variant F Airplanes (Collectively Called A300-600 Series Airplanes); and Model A310-200 and -300 Series Airplanes
This AD applies to Airbus Model A300 B2-1A, B2-1C, B2K-3C, B4-2C, B4-103, and B4-203 airplanes; A300 B4-601, B4-603, B4-620, B4-622, B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes; and A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes; certificated in any category; except those on which both Airbus Modifications 5946 and 8057 were done during production.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus airplane models, as specified above. This AD requires modifying the thermal insulation system of certain fuselage frames, and modifying the fuselage drainage system. This AD also requires revising the FAA-approved maintenance inspection program to include inspections for corrosion or cracking in the subject areas. This AD is prompted by reports of corrosion in the lower part of the pressure bulkhead at certain fuselage frames. We are issuing this AD to prevent accumulation of condensation in the insulation blankets of certain fuselage frames, which could cause corrosion that could result in reduced structural integrity of the fuselage and consequent rapid decompression of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 22 months after the effective date of this AD, modify the thermal insulation system of applicable fuselage frames and modify the fuselage drainage system, by doing all actions in the Accomplishment Instructions of the applicable service bulletins specified in Table 1 of this AD.
| For Airbus models— | Modify the thermal insulation system according to Airbus Service Bulletin— | And modify the fuselage drainage system according to Airbus Service Bulletin— |

Within 90 days after doing the actions required by paragraph (f) of this AD, or within 90 days after the effective date of this AD, whichever is later: Incorporate into the FAA-approved maintenance inspection program repetitive detailed inspections for corrosion or cracking of fuselage structure from FR 38.2 to 39, and at FR 54, as applicable, as described in Airbus Maintenance Planning Document Task Numbers 538295-0603-1 (for Airbus Model A300 B2-1A, B2-1C, B2K-3C, B4-2C, B4-103, and B4-203 airplanes), and 531531-01-1 and 531533-01-1 (for Airbus Model A300 B4-601, B4-603, B4-620, B4-622, B4-605R, F4-605R, F4-622R, B4-622R, and C4-605R Variant F airplanes; and A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes). Then, thereafter, comply with the applicable requirements.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
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.
