14 CFR Part 39

[Docket No. FAA-2006-24289; Directorate Identifier 2005-NM-186-AD]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A300 Airplanes; 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 A310 Airplanes

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

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: The FAA is revising an earlier NPRM for an airworthiness 
directive (AD) that applies to all Airbus airplanes identified above. 
The original NPRM would have required improving the routing of certain 
electrical wire bundles in certain airplane zones, as applicable to the 
airplane model. The original NPRM resulted from fuel system reviews 
conducted by the manufacturer. This action revises the original NPRM by 
removing certain requirements, extending the compliance time for a 
certain replacement, and specifies that the actions in this proposed AD 
are considered interim action until a terminating action for the 
removed requirements is approved and available. We are proposing this 
supplemental NPRM to reduce the potential of ignition sources inside 
fuel tanks, which, in combination with flammable fuel vapors, could 
result in fuel tank explosions and consequent loss of the airplane.

DATES: We must receive comments on this supplemental NPRM by October 6, 
2006.

Discussion

    We proposed to amend 14 CFR part 39 with a notice of proposed 
rulemaking (NPRM) for an airworthiness directive (AD) (the ``original 
NPRM''). The original NPRM applies to all Airbus Model A300 B2 and A300 
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 A310-200 and -300 series 
airplanes. The original NPRM was published in the Federal Register on 
April 4, 2006 (71 FR 16716). The original NPRM proposed to require 
improving the routing of certain electrical wire bundles in certain 
airplane zones, as applicable to the airplane model.
    Since the original NPRM was issued, the European Aviation Safety 
Agency (EASA) has superseded French airworthiness directive F-2005-112 
R1, dated September 14, 2005, which was referenced as the parallel 
airworthiness directive for the actions in the original NPRM. EASA 
airworthiness directive 2006-0074, dated April 3, 2006, removes Actions 
1 and 2 and specifies that a new EASA airworthiness directive is 
planned in the future to mandate the embodiment of certain new service 
information that will render Actions 1 and 2 null and void.
    Actions 1 and 2 were:
     Action 1--Install a heat-shrinkable sleeve along the 
complete length of the electrical supply bundle of the fuel pumps. 
These electrical supply bundles

[[Page 53342]]

are located in metallic protective conduits in zones 571 and 671.
     Action 2--Install a heat-shrinkable sleeve along the 
complete length of the electrical supply bundle of the fuel pumps. 
These electrical supply bundles are located in metallic protective 
conduits in zones 575 and 675.
    In this supplemental NPRM, we have removed the service bulletins 
that were referenced as the appropriate sources of service information 
for doing Actions 1 and 2 in the original NPRM. The service bulletins 
are described in the following table.

    We have also removed Airbus Service Bulletins A300-28-6010, 
Revision 1, dated September 17, 1986; and A310-28-2008, Revision 2, 
dated May 14, 1990; which were referenced in the original NPRM as 
prior/concurrent service bulletins for Actions 1 and 2. We have also 
removed Airbus Service Bulletins A300-24-0073, Revision 04, dated June 
30, 1998; and A300-24-6004, Revision 03, dated June 30, 1998; which 
were referenced in the original NPRM as prior/concurrent service 
bulletins for Action 3. Airbus has informed us that the actions in 
Airbus Service Bulletins A300-24-0073 and A300-24-6004 are recommended 
as complementary measures to improve the trailing edge electrical 
installation reliability, but are not required for accomplishing Action 
3. However, Airbus Service Bulletin A300-24-6004 is still specified as 
a requirement for accomplishing Action 5.

Relevant Service Information

    Airbus has issued the service bulletins identified in the following

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

    EASA mandated the service information and issued EASA airworthiness 
directive EASA airworthiness directive 2006-0074, dated April 3, 2006, 
to ensure the continued airworthiness of these airplanes in the 
European Union.

Comments

    We have considered the following comments on the original NPRM.

Requests To Extend Compliance Time

    FedEx, and Air Transport Association (ATA), on behalf of its member 
American Airlines (AAL), request that we extend the compliance time. 
FedEx states that the proposed compliance time of 26 months after the 
effective date of the AD is not acceptable and states that it requires 
43 months after the effective date to comply. FedEx's comment implies 
that the 43-month compliance time would better align with its 
maintenance schedule. AAL requests a 30-month compliance time to align 
with its maintenance schedule. The scope of the modifications is well 
beyond the capabilities of AAL's lower-level maintenance 
infrastructure. AAL is also concerned about kit availability and lead 
times. AAL states that the relevant reliability and service 
interruption data gathered since 1996 do not support the 26-month 
compliance time. AAL has had inspections in place for the affected area 
since 1996 and has had no significant findings that would indicate re-
emergence of the unsafe condition specified in the original NPRM. In 
addition, AAL states that it has implemented mitigation techniques that 
are similar but less costly than those described in the referenced 
serviced bulletins.
    We disagree with the commenters. We have determined that the 
compliance time, as proposed, represents the maximum interval of time 
allowable for the affected airplanes to continue to safely operate 
before the modification is done. In addition, we have confirmed with 
the parts manufacturer that parts will be available to operators within 
the timeframe proposed in this supplemental NPRM. However, operators 
may request an Alternative Method of Compliance (AMOC) in accordance 
with the procedures specified in paragraph (l) of this supplemental 
NPRM.

Request for Editorial Changes

    Airbus notes that the original NPRM should be corrected in three 
areas: In paragraph (h)(2), Modification 11276 should be replaced by 
Modification 10505; in paragraph (j)(2), Modification 478 should be 
replaced by Modification 6478; and in paragraph (k), the phrase ``* * * 
with new metallic clamps * * *; or replace * * * '' should be replaced 
by ``* * * with new metallic clamps * * * and/or replace.''
    We agree with Airbus. We have made the noted editorial changes in 
the applicable paragraphs of the supplemental NPRM.

Request To Withdraw Action

    ATA, on behalf of AAL, notes that some of the service bulletins in 
the original NPRM had been released as early as 1988 without the FAA 
taking

[[Page 53343]]

AD action. The commenters state that this indicates that at the time 
the inherent safety risk was not considered to be significant enough to 
warrant regulatory action.
    We infer that the commenters are requesting that we withdraw the 
supplemental NPRM because the action is not warranted. We disagree. As 
stated in the original NPRM, we issued a regulation titled ``Transport 
Airplane Fuel Tank System Design Review, Flammability Reduction and 
Maintenance and Inspection Requirements'' (67 FR 23086, May 7, 2001). 
In addition to new airworthiness standards for transport airplanes and 
new maintenance requirements, this rule included Special Federal 
Aviation Regulation No. 88 (``SFAR 88,'' Amendment 21-78, and 
subsequent Amendments 21-82 and 21-83). Among other actions, SFAR 88 
requires certain type design (i.e., type certificate (TC) and 
supplemental type certificate (STC)) holders to substantiate that their 
fuel tank systems can prevent ignition sources in the fuel tanks. This 
requirement applies to type design holders for large turbine-powered 
transport airplanes and for subsequent modifications to those 
airplanes. It requires them to perform design reviews and to develop 
design changes and maintenance procedures if their designs do not meet 
the new fuel tank safety standards. As explained in the preamble to the 
original NPRM, we intended to adopt airworthiness directives to mandate 
any changes found necessary to address unsafe conditions identified as 
a result of these reviews.
    The Joint Aviation Authorities (JAA) have issued a regulation that 
is similar to SFAR 88. (The JAA is an associated body of the European 
Civil Aviation Conference (ECAC) representing the civil aviation 
regulatory authorities of a number of European States who have agreed 
to co-operate in developing and implementing common safety regulatory 
standards and procedures.) Under this regulation, the JAA stated that 
all members of the ECAC that hold type certificates for transport 
category airplanes are required to conduct a design review against 
explosion risks.
    The original NPRM and this supplemental NPRM follow from those 
rulings. As such, they may make use of service information issued 
previously but not mandated by AD action.

Explanation of Change in Applicability

    We have revised the applicability to more closely match the 
effectivity of the EASA airworthiness directive. This change does not 
expand the applicability of this proposed action.

Explanation of Change in Compliance Time of Paragraph (h)

    Paragraph (h) of the NPRM specifies to do the replacement ``within 
24 months after the effective date of this AD'' and to repeat 
thereafter at intervals not to exceed 24 months. We have revised the 
compliance times in paragraph (h) of this supplemental NPRM to specify 
a compliance time of ``within 26 months after the effective date of 
this AD'' and to repeat thereafter at intervals not to exceed 26 
months. We have determined that extending the compliance time will not 
adversely affect safety and will allow operators to coordinate the 
replacement specified in paragraph (h) of this supplemental NPRM with 
the other actions specified in this supplemental NPRM. This difference 
has been coordinated with the EASA.

FAA's Determination and Proposed Requirements of the Supplemental NPRM

    The changes discussed above expand the scope of the original NPRM; 
therefore, we have determined that it is necessary to reopen the 
comment period to provide additional opportunity for public comment on 
this supplemental NPRM.

Interim Action

    We consider this proposed AD interim action. EASA has informed us 
that the manufacturer is currently developing an additional 
modification that will address the unsafe condition identified in this 
AD. Once this modification is developed, approved, and available, we 
may consider additional rulemaking.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this supplemental NPRM.
    This supplemental NPRM would affect about 169 airplanes of U.S. 
registry. The following table provides the estimated costs for U.S. 
operators to comply with this supplemental NPRM. The average labor rate 
is $80 per work hour.

    Based on these figures, the estimated cost of the supplemental NPRM 
for U.S. operators is up to $2,939,924, or up to $17,396 per airplane.

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;

[[Page 53344]]

    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 supplemental NPRM and placed it in the AD docket. See 
the ADDRESSES section for a location to examine the regulatory 
evaluation.
