Airbus Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, B4-622R, F4-605R, F4-622R, and C4-605R Variant F Series Airplanes Equipped With Simmonds Precision Products, Inc., Fuel Quantity Indicating System Sensors and In-Tank Harnesses Installed in Accordance With Supplemental Type Certificate (STC) ST00092BO
This AD applies to Airbus Model A300 B4-601, B4-603, B4-605R, B4-620, B4-622, B4-622R, F4-605R, F4-622R, and C4-605R Variant F series airplanes, certificated in any category, equipped with Simmonds Precision Products, Inc., Fuel Quantity Indicating System sensors and in-tank harnesses installed in accordance with Supplemental Type Certificate (STC) ST00092BO.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (o) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
We are adopting a new airworthiness directive (AD) for certain Airbus model series airplanes listed above. This AD requires revising the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness to incorporate new fuel system limitations for airplanes modified in accordance with Supplemental Type Certificate (STC) ST00092BO. This AD also requires a general visual inspection for tank unit separation and compensator separation of the center, inner, and outer fuel tanks, and trim fuel tanks of the tank units, and corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent a potential of ignition sources inside fuel tanks, which in combination with flammable fuel vapors, could result in a fuel tank fire or explosion and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless already done.
Within 30 days after the effective date of this AD, revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness to incorporate the inspections specified in Section 2.2.3 of the Goodrich A300-600 Instructions for Continued Airworthiness, Document T3012-0005-0101, Revision B, dated June 12, 2008.
Within 6 months after the effective date of this AD, do a general visual inspection for tank unit separation and compensator separation of the center, inner, and outer fuel tanks, and trim fuel tanks of the tank units, in accordance with Section 2.2.3 of the Goodrich A300-600 Instructions for Continued Airworthiness, Document T3012-0005-0101, Revision B, dated June 12, 2008. If incorrect separation is found, before further flight, correct the separation in accordance with the Airplane Maintenance Manual for the corresponding inspection specified in Section 2.2.3 of the Goodrich A300-600 Instructions for Continued Airworthiness, Document T3012-0005-0101, Revision B, dated June 12, 2008. A review of airplane maintenance records is acceptable in lieu of this inspection if the requirement of Table 6 in Section 10.1 of the Goodrich A300-600 Instructions for Continued Airworthiness, Document T3012-0005-0101, Revision B, dated June 12, 2008, can be conclusively determined to have been done from that review.
(i) Within 30 days after the effective date of this AD, revise the ALS of the Instructions for Continued Airworthiness to incorporate the CDCCLs, as defined in Section 10.1 of the Goodrich A300-600 Instructions for Continued Airworthiness,
Document T3012-0005-0101, Revision B, dated June 12, 2008.
(j) Except as provided by paragraph (o) of this AD: After accomplishing the actions specified in paragraphs (g) and (i) of this AD, no alternative inspection, inspection intervals, or CDCCLs may be used.
Note 2: Notwithstanding any other maintenance or operational requirements, components that have been identified as airworthy or installed on the affected airplanes before the revision of the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness, as required by paragraph (i) of this AD, do not need to be reworked in accordance with the CDCCLs. However, once the Airworthiness Limitations Section of the Instructions for Continuing Airworthiness has been revised, future maintenance actions on these components must be done in accordance with the CDCCLs.
Inspections are acceptable for compliance with the requirements of paragraph (h) of this AD, if done before the effective date of this AD, in accordance with Goodrich Service Bulletin 300723-0101-28-01, dated April 15, 2004.
(l) Inspections are also acceptable for compliance with the requirements of paragraph (h) of this AD, if done before the effective date of this AD, in accordance with Goodrich Service Bulletin 300723-0101-28-01, Revision 1, dated July 1, 2004.
Doing the inspections in Section 2.2.3 of the Goodrich A300-600 Instructions for Continued Airworthiness, Document T3012-0005-0101, Revision B, dated June 12, 2008, is considered an acceptable method of compliance with paragraphs (b) and (c) of AD 2004-05-05.
(n) Doing the inspections in accordance with Goodrich Service Bulletin 300723-0101-28-01, Revision 1, dated July 1, 2004, is an acceptable method of compliance with paragraphs (b) and (c) of AD 2004-05-05.
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.
