Airworthiness Directives; Airbus Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for all Airbus Model A300 B4-600, B4-600R and A300 F4-600R series 
airplanes, Model A300 C4-605R Variant F airplanes, and Model A310 
series airplanes. That AD currently requires modifying the wiring in 
the right-hand electronics rack. This new AD requires replacing the 
cockpit multi-tank indicators (MTI), and for certain airplanes, 
replacing high-level, low-level, and overflow sensors and their harness 
connectors, and re-instating the low-level warning indication to the 
cockpit MTI. This AD was prompted by reports of failures of four fuel 
level sensor-amplifier and MTI units. This AD also adds Model A310 
series airplanes to the applicability. We are issuing this AD to 
prevent degradation of the electrical insulation sleeves of the low-
level indication lamps on the MTI, which could cause a short circuit 
that might result in high voltage being conveyed to the high- and low-
level sensors in the wing tanks. This condition could cause the level 
sensor to heat above acceptable limits, possibly resulting in a fuel 
tank explosion, and consequent loss of the airplane.

DATES: This AD becomes effective July 23, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of July 23, 
2012.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of March 
27, 2009 (74 FR 7792, February 20, 2009).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on November 7, 2011 (76 
FR 68671), and proposed to supersede AD 2009-02-04, Amendment 39-15794 
(74 FR 7792, February 20, 2009). That NPRM proposed to correct an 
unsafe condition for the specified products. The MCAI states:

    One operator experienced failures of four Fuel Level Sensor-
Amplifier (FLSA) and Multi Tank Indicators (MTI) units. FLSA and MTI 
failures have been identified as having been caused by incorrect 
connector sleeves materials fitted to the MTI units.
    Degradation of the electrical insulation sleeves of the Low-
level indication lamps on the MTI of the flight deck can cause a 
short circuit that might result in high voltage being conveyed to 
the high and low level sensors in the wing tanks. This condition, if 
not corrected, could cause the level sensor to heat above acceptable 
limits, possibly resulting in fuel tank explosion, and consequent 
loss of the aeroplane.
    As an interim action, EASA AD 2008-0055 [which corresponds to 
FAA AD 2009-02-04, Amendment 39-15794 (74 FR 7792, February 20, 
2009)], was issued requiring the accomplishment of wiring 
modifications to protect the FLSA and the Flight Warning Computers 
from 115V [volt] AC [alternating current] and 28V DC [direct 
current] short circuits within the cockpit MTI.
    EASA AD 2009-0144, which required the replacement of the 
affected sensors and their harness connectors with modified units in 
accordance with the instructions of Airbus Service Bulletin (SB) 
A300-28-6095 at original issue or SB A300-28-9013 at original issue, 
as applicable, was further on cancelled because the installation of 
the new inner tank fused low-level sensors was not possible, due to 
interference between some sensors and a fuel pipe at connector 
level.
    Airbus SB A300-28-6095 and SB A300-28-9013 have been revised to 
clear this interference. The replacement of the affected sensors and 
their harness connectors according to the instructions of these SBs 
is now possible.
    This [EASA] AD supersedes [EASA] AD 2008-0055 and introduces the 
following actions:

--Expanding of the applicability to A310 aeroplanes; and
--Replacement of the cockpit MTI with a MTI with silicone sleeves 
and to reinstate the low level warning indication to the cockpit 
MTI; and
--Replacement of the affected sensors and their harness connectors 
by fused level sensor units for A300-600 and A300-600ST aeroplanes.

You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received.

Requests for Extension of Compliance Time

    UPS requested that we extend the compliance time specified in 
paragraphs (h), (i), and (j) in the NPRM (76 FR 68671, November 7, 
2011) to 60 months. UPS explained that the requested extended 
compliance time is to reduce the potential for special maintenance 
visits of its airplanes, and that a compliance period of less than 60 
months will cause undue hardship on UPS and its operation, and result 
in significant negative economic impact.

[[Page 36147]]

UPS reasoned that it has an existing tank entry program that is 
completed only during airplane major maintenance visits at a 5-year 
time interval, and that using the existing interval will reduce the 
costs to open, purge, close, and check out the tanks. UPS explained 
further, that materials will take a minimum of 6 months to receive, and 
due to the extensive time waiting for parts, this will force even more 
airplanes into a special visit program in a much shorter period of time 
than what the NPRM is proposing.
    UPS expressed that it agrees with the FAA when the premise for 
establishing a timeline for completion of an SFAR (Special Federal 
Aviation Regulation) 88 project is based on a level of safety as 
determined by the NPRM (76 FR 68671, November 7, 2011) and that it 
believes there is a timeframe precedence that has previously been set 
by the FAA for a project of this type. UPS explained that the FAA 
released an earlier AD, which corrected similar actions to the NPRM (76 
FR 68671, November 7, 2011), and that the earlier AD had a 5-year 
compliance requirement. UPS believes that the same level of safety is 
achieved with a 5-year compliance on the Model A300 airplanes fleet.
    FedEx requested that we extend the compliance time in the NPRM (76 
FR 68671, November 7, 2011) to 30 months, to allow for the 
accomplishment of the work to be performed at a scheduled heavy 
maintenance event. FedEx explained that it accomplishes a heavy 
maintenance check on its Model A300-600 and A310 airplanes every 30 
months. FedEx reasoned that it would be 22 hours per airplane to 
accomplish the requirements of the service information and that it is a 
significant economic and operational hardship for it to ``special 
visit'' airplanes to accomplish fuel tank entry.
    We do not agree to extend the compliance time in this final rule. 
In developing an appropriate compliance time for this action, we 
considered the urgency associated with the subject unsafe condition, 
the availability of required parts, and the practical aspect of 
accomplishing the required modification within a period of time that 
corresponds to the normal scheduled maintenance for most affected 
operators. Under the provisions of paragraph (m) of the final rule, we 
will consider requests for approval of an extension of the compliance 
time if sufficient data are submitted to substantiate that the new 
compliance time would provide an acceptable level of safety. We have 
not changed the AD in this regard.

Requests for Revision to Costs of Compliance

    UPS requested that we revise the Costs of Compliance section in the 
NPRM (76 FR 68671, November 7, 2011). UPS explained that it has 
determined that the required hours to complete the NPRM are greater 
than 150 hours and that the material kits that are required by Airbus 
Mandatory Service Bulletin A300-28-6095, Revision 01, dated February 2, 
2010, are approximately $40,000 each, which is a total of $52,750 per 
airplane. UPS reasoned that the completion of the modification on the 
53 UPS Model A300 airplanes will be approximately $2,795,750, which is 
a significant negative economic impact on UPS. UPS expressed that the 
proposed cost in the NPRM is only 7.5 percent of the actual cost that 
UPS will incur and that the actual costs will be greater than 13 times 
the cost estimates proposed in the NPRM.
    FedEx requested that we acknowledge that there is an additional 
material cost and that our Costs of Compliance section in the NPRM (76 
FR 68671, November 7, 2011) is underestimated in terms of financial 
impact to the operator. FedEx reasoned that the estimated parts cost 
for accomplishment of Airbus Mandatory Service Bulletin A300-28-6095, 
Revision 01, dated February 2, 2010, only includes the Airbus 
manufactured hardware kit (P/N 286095B01R01). FedEx explained that in 
order to complete the modification, a separate Intertechnique kit that 
includes the actual sensors and harness connectors must be procured, 
and that Airbus Mandatory Service Bulletin A300-28-6095, Revision 01, 
dated February 2, 2010, provides no warranty information or pricing for 
the additional required kit. FedEx expressed that it is in the process 
of obtaining price information for the additional required 
Intertechnique kits and will provide the data when it becomes 
available.
    We agree to revise the Costs of Compliance section in this final 
rule for the reasons stated by the commenters. We have revised the 
Costs of Compliance section of the final rule to include the average 
costs of parts from Intertechnique.

Revised Paragraph Header and Wording

    We have revised the heading for and the wording in paragraph (k) of 
this AD and the wording of paragraph (g) of this AD; these changes have 
not affected the intent of those paragraphs.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously--except for minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (76 FR 68671, November 7, 2011) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (76 FR 68671, November 7, 2011).

Costs of Compliance

    We estimate that this AD will affect about 210 products of U.S. 
registry. The actions that are required by AD 2009-02-04, Amendment 39-
15794 (74 FR 7792, February 20, 2009), and retained in this AD take 
about 5 work-hours per product, at an average labor rate of $85 per 
work-hour. Required parts cost about $0 per product. Based on these 
figures, the estimated cost of the currently required actions is $425 
per product.
    We estimate that it will take about 44 work-hours per product to 
comply with the new basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $39,000 per 
product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of this AD to the 
U.S. operators to be $8,975,400, or $42,740 per product.

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

[[Page 36148]]

because it addresses an unsafe condition that is likely to exist or 
develop on products identified in this rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will 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 this AD:
    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);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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 AD and placed it in the AD docket.
