Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Airbus Model A330-200 and -300 series airplanes, Model A330-200 
Freighter series airplanes, and Airbus Model A340-541 and A340-642 
airplanes. This proposed AD was prompted by a report of an under-
torqued forward engine mount bolt. This proposed AD would require a 
one-time torque check of the forward and aft engine mount bolts, and 
corrective actions if necessary. We are proposing this AD to detect and 
correct improperly torqued engine mount bolts, which could lead to 
detachment of the engine from the airplane during flight; and 
consequent damage to the airplane and injury to persons on the ground.

DATES: We must receive comments on this proposed AD by February 12, 
2016.

Discussion

    The European Aviation Safety Agency, which is the Technical Agent 
for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0082, dated May 11, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition on certain Airbus Model 
A330-200 and -300 series airplanes, Model A330-200 Freighter series 
airplanes, and Airbus Model A340-541 and A340-642 airplanes. The MCAI 
states:

    In 2013, during a pre-delivery test on an A330 aeroplane fitted 
with Pratt & Whitney (PW) PW4170 engines, an issue with N1 
vibrations level on [engine] ENG1 was identified. While performing 
an engine removal, one forward engine mount bolt was found 
improperly torqued. The investigation concluded this was due to a 
production line engine installation quality issue. Further analysis 
showed that some aeroplanes, delivered between June 2006 and January 
2014, may have had the rear (AFT) and forward (FWD) engine mount 
bolts improperly torqued.
    This condition, if not detected and corrected, could ultimately 
lead to an in-flight detachment of the engine from the aeroplane, 
possibly resulting in damage to the aeroplane and/or injury to 
persons on the ground.
    Prompted by these findings, Airbus issued four Alert Operators 
Transmissions (AOT) A71L004-14 (for A330 aeroplanes fitted Pratt & 
Whitney (PW) engines), AOT A71L006-14 (for A330 aeroplanes fitted 
with General Electric (GE) engines), AOT A71L005-14 (for A330 
aeroplanes fitted with Rolls Royce (RR) Trent 700 engines) and AOT 
A71L008-14 (for A340 aeroplanes fitted with RR Trent 500 engines) to 
provide torque check instructions.
    For the reasons described above, this [EASA] AD requires a one-
time torque check of the FWD and AFT engine mount bolts and, 
depending on findings, [corrective actions] re-torque of the 
affected bolt(s) and/or replacement of all four bolts and associated 
nuts.

    Findings (or discrepancies) include one bolt that is loose or able 
to rotate, two or more bolts that are loose or able to rotate, or one 
or more pylon bolts that are fully broken. Corrective actions include 
re-torqueing the affected bolt(s), and replacing all bolts and 
associated nuts with new bolts and nuts on the engine where the loose 
or fully broken bolt(s) were detected. This proposed AD specifies 
reporting of all findings (including no discrepancies). The corrective 
actions include re-torqueing loose bolts before further flight. The 
compliance times for replacing loose or fully broken bolts ranges, 
depend on airplane configuration, and range from before further flight 
if more than one bolt rotates or is fully broken to no later than 2,350 
flight cycles or 24,320 flight hours since first flight of the 
airplane, if only one bolt rotates. You may examine the MCAI in the AD 
docket on the Internet at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2015-7533.

Related Service Information Under 1 CFR Part 51

    We have reviewed the following service information.
     Airbus AOT A71L004-14, Revision 01, dated April 7, 2014. 
The service information describes procedures for doing a one-time 
torque check to determine if there are any loose or fully broken engine

engines, doing corrective actions, and reporting all findings.
     Airbus AOT A71L005-14, Revision 01, dated December 11, 
2014. The service information describes procedures for doing a one-time 
torque check to determine if there are any loose or fully broken engine 
mount pylon bolts at four positions at the forward engine pylon 1 and 
pylon 2 of Airbus Model A330 series airplanes having Trent 700 engines, 
doing corrective actions, and reporting all findings.
     Airbus AOT A71L006-14, dated July 22, 2014. The service 
information describes procedures for doing a one-time torque check to 
determine if there are any loose or fully broken engine mount pylon 
bolts at five FWD and four AFT positions at the forward engine pylon 1 
and pylon 2 of Airbus Model A330 series airplanes having GE engines, 
doing corrective actions, and reporting all findings.
     Airbus AOT A71L008-14, Revision 01, dated December 18, 
2014. The service information describes procedures for doing a one-time 
torque check to determine if there are any loose or fully broken engine 
mount pylon bolts at four positions at the forward engine pylon 1 and 
pylon 2 of Airbus Model A340 series airplanes having Trent 500 engines, 
doing corrective actions, and reporting all findings.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section of this 
NPRM.

Other Related Rulemaking

    On June 21, 2013, we issued AD 2013-14-04, Amendment 39-17509 (78 
FR 68352, November 14, 2013). AD 2013-14-04 requires a torque check of 
forward engine mount bolts, and replacement if necessary on all Airbus 
Model A330-223F, -223, -321, -322, and -323 airplanes. AD 2013-14-04 
was

[[Page 81218]]

prompted by a fatigue load analysis that determined that the inspection 
interval for certain pylon bolts must be reduced. We issued AD 2013-04-
04 to detect and correct loose or broken bolts, which could lead to 
engine detachment in-flight, and damage to the airplane.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 55 airplanes of U.S. 
registry.
    We also estimate that it would take about 12 work-hours per product 
to comply with the basic requirements of this proposed AD, and 1 work-
hour per product to report torque check findings. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this proposed AD on U.S. operators to be $60,755, or $1,105 per 
product.
    In addition, we estimate that any necessary follow-on actions would 
take about 20 work-hours and require parts costing $90,200 for a cost 
of $91,900 per product. We have no way of determining the number of 
aircraft that might need these actions.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this proposed AD 
is 2120-0056. The paperwork cost associated with this proposed AD has 
been detailed in the Costs of Compliance section of this document and 
includes time for reviewing instructions, as well as completing and 
reviewing the collection of information. Therefore, all reporting 
associated with this proposed AD is mandatory. Comments concerning the 
accuracy of this burden and suggestions for reducing the burden should 
be directed to the FAA at 800 Independence Ave. SW., Washington, DC 
20591, ATTN: Information Collection Clearance Officer, AES-200.

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 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 this 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);
    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.
