14 CFR Part 39

[Docket No. FAA-2016-9074; Directorate Identifier 2016-NM-097-AD]
RIN 2120-AA64


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 all 
Airbus Model A318-111 and -112 airplanes, Model A319-111, -112, -113, -
114, and -115 airplanes, Model A320-211, -212, and -214 airplanes, and 
Model A321-111, -112, -211, -212, and -213 airplanes. This proposed AD 
was prompted by reports of engine fan cowl door (FCD) losses on 
airplanes equipped with CFM56 engines due to operator failure to close 
the FCD during ground operations. This proposed AD would require 
modification and re-identification of certain FCDs or replacement of 
certain FCDs. This proposed AD would also require installation of a 
placard. We are proposing this AD to prevent in-flight loss of an 
engine FCD and possible consequent damage to the airplane.

DATES: We must receive comments on this proposed AD by November 10, 
2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive, 2016-0069, dated April 11, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318-111 and -112 airplanes, Model A319-111, -112, -113, -114, and -115 
airplanes, Model A320-211, -212, and -214 airplanes, and Model A321-
111, -112, -211, -212, and -213 airplanes. The MCAI states:

    Fan Cowl Door (FCD) losses were reported on aeroplanes equipped 
with CFM56 engines.
    Investigations confirmed that in all cases the fan cowls were 
opened prior to the flight and were not correctly re-secured. During 
the pre-flight inspection, it was then not detected that the FCD 
were not properly latched.
    This condition, if not detected and corrected, could lead to in-
flight loss of a FCD, possibly resulting in damage to the aeroplane 
and/or injury to persons on the ground.
    Prompted by these events, new FCD front latch and keeper 
assembly were developed, having a specific key necessary to un-latch 
the FCD. This key cannot be removed unless the FCD front latch is 
safely closed. The key, after removal, must be stowed in the flight 
deck at a specific location, as instructed in the applicable 
Aircraft Maintenance Manual. Applicable Flight Crew Operating Manual 
has been amended accordingly. After modification, the FCD is 
identified with a different Part Number (P/N).
    For the reasons described above, this [EASA] AD requires 
modification and re-identification of FCD [or replacement of the 
FCD].

    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-2016-
9074.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Service Bulletin A320-71-1068, Revision 01, 
dated April 28, 2016. This service information describes procedures for 
modifying the left-hand and right-hand FCDs on engines 1 and 2; 
installing a placard;

[[Page 65981]]

and re-identifying both the left-hand and right-hand FCDs with the new 
part number. 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.

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.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The parts installation prohibition specified in paragraph (5) of 
the MCAI depends on the configuration of the airplane. However, 
paragraph (k) of this proposed AD prohibits installing certain parts 
for all airplanes as of the effective date of this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 400 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

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

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.

(h) Replacement of Affected Fan Cowl Door With New Door Design

    Replacing the FCDs, having a part number listed as ``Old P/N'' 
in table 1 to paragraphs (g), (h), (i), and (k) of this AD, with the 
FCDs having the corresponding part number listed as ``New P/N'' in 
table 1 to paragraphs (g), (h), (i), and (k) of this AD, is equal to 
compliance with paragraphs (g)(1) and (g)(3) of this AD. The 
replacement must be done in accordance with instructions approved by 
the Manager, International Branch, ANM-116, Transport Airplane 
Directorate, FAA; or the European Aviation Safety Agency (EASA), or 
approved under Airbus's EASA Design Organization Approval (DOA).

(i) Compliance Information for Airplanes on Which Airbus Modification 
157517 Is Embodied

    An airplane on which Airbus modification 157517 has been
