Start Preamble

AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to all Airbus Model A300-600 series airplanes. The existing AD currently requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. The existing AD also provides for optional terminating action for certain inspections. This proposed AD would retain all requirements of the existing AD, mandate the previously optional terminating action, reduce the applicability of the existing AD, and add repetitive inspections behind scuff plates for certain affected airplanes. This proposed AD results from a determination that further rulemaking is necessary to improve the fatigue behavior of the cabin door surroundings. We are proposing this AD to prevent corrosion between the scuff plates at exit and cargo doors and fatigue cracks originating from certain fastener holes located in adjacent structure, which could result in reduced structural integrity of the door surroundings.

DATES:

We must receive comments on this proposed AD by February 20, 2007.

Discussion

On July 24, 1998, we issued AD 98-16-05, amendment 39-10680 (63 FR 40812, July 31, 1998), for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4-605R Variant F airplanes (collectively called A300-600 series airplanes). That AD requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also provides for optional terminating action for certain inspections. That AD resulted from reports indicating that corrosion was found behind the scruff plates at exit and cargo doors, and fatigue cracks originated from certain fastener holes located in adjacent structure. We issued that AD to detect and correct such corrosion and fatigue cracking, which could result in reduced structural integrity of the door surroundings.

Other Relevant Rulemaking

We have previously issued AD 97-11-03, amendment 39-10032 (62 FR 28325, May 23, 1997), applicable to all Airbus Model A300 series airplanes. That AD requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also requires modification of the passenger/crew door frames, which terminates certain inspections.

We also previously issued AD 98-16-06, amendment 39-10682 (63 FR 40819, July 31, 1998), for all Airbus Model A310 series airplanes. That AD requires inspections of the lower door surrounding structure to detect cracks and corrosion; inspections to detect cracking of the holes of the corner doublers, the fail-safe ring, and the door frames of the door structures; and repair if necessary. That AD also provides for optional terminating action for certain inspections. We are considering further rulemaking to mandate the optional terminating action.

Actions Since Existing AD Was Issued

Since we issued AD 98-16-05, the Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, issued French airworthiness directives 1991-132-124(B) R1, dated November 29, 2000 (to replace French airworthiness directive 91-132-124(B), dated June 26, 1991, which is referred to in AD 98-16-05), and F-2004-103, dated July 7, 2004. The DGAC advises that further rulemaking is necessary to improve the fatigue behavior of the cabin door surroundings on certain Airbus Model A300-600 series airplanes and to remove certain airplanes from the applicability of the existing AD that are no longer subject to the existing requirements. Corrosion between the scuff plates at exit and cargo doors and fatigue cracks originating from certain fastener holes located in adjacent structure, if not corrected, could result in reduced structural integrity of the door surroundings.

After the DGAC issued French airworthiness directive 1991-132-124(B) R1 on November 29, 2000, we determined at that time that further rulemaking was not necessary, because the changes to AD 98-16-05 would be relieving in nature. However, since French airworthiness directive F-2004-103 mandates the previously optional modification, we now agree with the DGAC that further rulemaking is indeed necessary to improve the fatigue behavior of the cabin door surroundings, and this proposed AD follows from that determination.

Relevant Service Information

Airbus has issued and revised the service bulletins in the following table:

Service Bulletins

Airbus Service Bulletin—Describes procedures for—
A300-53-6011, Revision 07, dated January 24, 2005 (Revision 3, dated February 4, 1991, of the service bulletin was referenced in AD 98-16-05 as an appropriate source of service information)Doing initial inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door, and repairing any cracked or corroded part or contacting Airbus. The inspection and repair are essentially identical to those specified in Revision 3 of the service bulletin. Revision 07 also revises the effectivity by adding additional airplanes.
A300-53-6022, Revision 04, dated January 24, 2005 (the original issue, dated February 4, 1991, of the service bulletin was referenced in AD 98-16-05 as an appropriate source of service information)Doing repetitive inspections for cracks and corrosion of the areas behind the scuff plates below the passenger/crew doors and bulk cargo door, and repairing any cracked/corroded part or contacting Airbus. The inspection and repair are essentially identical to those specified in original issue of the service bulletin. Revision 04 also revises the effectivity by adding additional airplanes.
Start Printed Page 2471
A300-53-6018, Revision 03, dated July 26, 2006, including Appendix 01 (Revision 1, dated April 29, 1992, of the service bulletin was referenced in AD 98-16-05 as an appropriate source of service information)Doing repetitive inspections for cracks/corrosion of the holes of the corner doublers, the fail-safe ring, and the door frames of the passenger/crew door structures, and repairing any cracked/corroded part or contacting Airbus. The inspection and repair are essentially identical to those specified in Revision 1 of the service bulletin.
A300-53-6002, Revision 06, dated May 17, 2004 (Revision 3, dated February 22, 1992, of the service bulletin was referenced in AD 98-16-05 as an appropriate source of service information)Modifying the passenger/crew door structures, which ends the repetitive inspections of the holes of the corner doublers specified in Airbus Service Bulletin A300-53-6018, the fail-safe ring, and the door frames for certain airplanes. The modification includes cold expansion of fastener holes; a ROTO test; repair of any crack; repair of any crack that cannot be eliminated per Airbus; installation of new oversize fasteners and modified brackets; and installation of an additional steel doubler. The modification is essentially identical to that specified in Revision 3 of the service bulletin.

Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information to ensure the continued airworthiness of these airplanes in France.

FAA's Determination and Requirements of the Proposed AD

These airplane models are manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC's findings, evaluated all pertinent information, and determined that AD action is necessary for airplanes of this type design that are certificated for operation in the United States.

This proposed AD would supersede AD 98-16-05, retain the requirements of the existing AD, mandate the previously optional terminating action, reduce the applicability of the existing AD, and add repetitive inspections behind scuff plates for certain affected airplanes. This proposed AD would also require accomplishing the actions specified in service information described previously.

Difference Between French Airworthiness Directive and This Proposed AD

The applicability of French airworthiness directive 1991-132-124(B) R1 excludes Airbus Model A300-600 series airplanes on which Airbus Service Bulletin A300-53-6002, Revision 2, dated May 6, 1991 (or any other later approved revision), has been accomplished in service. However, we have not excluded those airplanes in the applicability of this proposed AD; rather, this proposed AD includes a requirement to accomplish the actions specified in Revision 06 of that service bulletin. This requirement would ensure that the actions specified in the service bulletin and required by this proposed AD are accomplished on all affected airplanes. Operators must continue to operate the airplane in the configuration required by this proposed AD unless an alternative method of compliance is approved.

The service bulletins specify to contact the manufacturer for instructions on how to repair certain conditions, but this proposed AD would require repairing those conditions using a method that we or the European Aviation Safety Agency (EASA) (or its delegated agent) approve. In light of the type of repair that would be required to address the unsafe condition, and consistent with existing bilateral airworthiness agreements, we have determined that, for this proposed AD, a repair we or the EASA approve would be acceptable for compliance with this proposed AD.

Change to Existing AD

This proposed AD would retain all requirements of AD 98-16-05. Since AD 98-16-05 was issued, the AD format has been revised, and certain paragraphs have been rearranged. As a result, the corresponding paragraph identifiers have changed in this proposed AD, as listed in the following table:

Revised Paragraph Identifiers

Paragraph (b)Paragraph (g).
Paragraph (c)Paragraph (h).
Paragraph (d)Paragraph (i).
Paragraph (e)paragraph (j).
Paragraph (f)Paragraph (k).
Paragraph (g)Paragraph (l).

The DGAC revised the applicability of French airworthiness directives 1991-132-124(B) R1 and F-2004-103 to exclude Model A300-600 series airplanes on which Airbus Modification 5068, 6514, 7201, and 7298 have been incorporated in production. Therefore, the applicability of the proposed AD parallels the French airworthiness directives in that regard.

Costs of Compliance

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, Section 106, describes the authority of the FAA Administrator. Subtitle VII, Aviation Programs, describes in more detail the scope of the Agency's authority.

We are issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701, “General requirements.” Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.

Regulatory Findings

We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would not have a substantial direct effect on the States, on the relationship between the national Government and the States, or on the distribution of power and responsibilities among the various levels of government.

For the reasons discussed above, I certify that the proposed regulation:

1. Is not a “significant regulatory action” under Executive Order 12866;

2. Is not a “significant rule” under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and

3. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.
