Airworthiness Directives; Airbus Model A319-100 and A320-200 
Series Airplanes

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

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Model A319-100 and A320-200 series airplanes. This 
proposed AD would require repetitive inspections of the wing-tank fuel 
pumps, canisters, and wing fuel tanks for detached identification 
labels, and corrective action if necessary. This proposed AD results 
from several incidents of detached plastic identification labels found 
floating in the wing fuel tanks. We are proposing this AD to prevent 
plastic identification labels being ingested into the fuel pumps and 
consequently entering the engine fuel feed system, which could result 
in an engine shutdown.

DATES: We must receive comments on this proposed AD by December 12, 
2005.

Discussion

    The Direction Generale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, notified us that an unsafe 
condition may exist on certain Airbus Model A319-100 and A320-200 
series airplanes. The DGAC advises that, in several incidents, plastic 
identification labels have been found floating in the fuel tanks. There 
are two types of labels and the information on the labels identifies 
each rib number in the vent box and the manhole door fasteners in the 
wing fuel tank, for inspection purposes. Inspection of the airplanes 
revealed that the varnish coating and adhesive on the labels had 
deteriorated and the labels detached from the wing structure. Detached 
labels floating in the fuel tank could be ingested into the fuel pumps 
and consequently enter into the engine fuel feed system. These 
conditions, if not corrected, could result in an engine shutdown.

Relevant Service Information

    Airbus has issued Service Bulletin A320-28-1102, Revision 01, dated 
February 11, 2005. The service bulletin describes procedures for 
repetitive detailed visual inspections of the four wing-tank fuel pumps 
and canisters for detached identification labels, and corrective action 
if necessary. The corrective action involves removing any label debris 
that is found, performing a detailed visual inspection for debris of 
the fuel filters and replacing the filters if necessary, and replacing 
the fuel pump if the inlet and outlet ports are blocked. The service 
bulletin also recommends sending an inspection report to Airbus.
    Airbus has also issued Service Bulletin A320-57-1117, dated July 
16, 2002. The service bulletin describes procedures for repetitive 
detailed visual inspections for detached identification labels in the 
collector cells between ribs 1 and 2, the surge tank between ribs 22 
and 26, and the wing fuel tank and vent box, and corrective action if 
necessary. The corrective action involves removing any label debris 
that is found, removing any partially detached labels, and re-
identifying certain fasteners and ribs.
    The DGAC mandated the service information and issued French 
airworthiness directive F-2005-121, dated July 20, 2005, 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 we need to 
issue an AD for airplanes of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously. For any wing-tank fuel pump failure that occurs, 
this proposed AD would also require performing a detailed inspection of 
the failed pump, the pump located in the same half wing, and the 
associated canister, and accomplishing any applicable corrective 
action, including replacing the pump.

Difference Between the Proposed AD and French Airworthiness Directive

    The French airworthiness directive mandates changes to the master 
minimum equipment list (MMEL). This proposed AD will not mandate those 
MMEL changes because the limits imposed by the FAA-approved MMEL meet 
or exceed those mandated by the French airworthiness directive. We have 
coordinated this issue with the DGAC.

Clarification of Inspection Terminology

    In this proposed AD, the ``detailed visual inspections'' specified 
in the service bulletins are referred to as ``detailed inspections.'' 
We have included the definition for a detailed inspection in a note in 
the proposed AD.

Costs of Compliance

    This proposed AD would affect about 74 airplanes of U.S. registry.
    The inspection specified in Service Bulletin A320-28-1102 would 
take about 3 work hours (including an operational test) per airplane, 
at an average labor rate of $65 per work hour. Based on these figures, 
the estimated cost of this proposed inspection for U.S. operators is 
$14,430, or $195 per airplane, per inspection cycle.
    The inspection specified in Service Bulletin A320-57-1117 would 
take about 6 work hours (including an operational test) per airplane, 
at an average labor rate of $65 per work hour. Based on these figures, 
the estimated cost of this proposed inspection for U.S. operators is 
$28,860, or $390 per airplane, per inspection cycle.

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

[[Page 68381]]

    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.
