The MCAI states: Fan Cowl Door (FCD) losses during take-off were reported on Airbus A320 family aeroplanes equipped with IAE [International Aero Engines] V2500 engines. Investigations confirmed that in all cases, the FCD were opened prior to the flight and were not correctly re-secured. During the pre-flight inspection, it was not detected that the FCD were not properly latched. This condition, if not corrected, could lead to in-flight loss of an FCD, possibly resulting in damage to the aeroplane and/or injury to persons on the ground. EASA issued AD 2016–0053 [which corresponds to FAA AD 2017–13–10, Amendment 39–18940 (82 FR 29371, June 29, 2017) (‘‘AD 2017–13–10’’)], requiring modification of the FCD installed on affected aeroplanes, and installation of a placard in the cockpit, in accordance with the instructions of Airbus Service Bulletin (SB) A320–71–1069 (which in turns refers to Goodrich SB V2500–NAC–71–0331 for FCD modification and re-identification). The monolithic FCDs, installed on aeroplanes embodying Short Brothers supplemental type certificate (STC) 10029547, are also affected by this potential unsafe condition. Consequently, the STC Holder, trading as Bombardier Short Brothers, developed a modification, similar to the one designed by Airbus, and issued SB V25MFC–71–1003. The modification consists of a new FCD front latch and keeper assembly, 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. The applicable Flight Crew Operating Manual has been amended accordingly. After modification, the FCD is identified with a different Part Number (P/N). Mixed FCD installation can be found on aeroplanes embodying [EASA] STC 10029547 (i.e., Monolithic FCD and standard production non-Monolithic FCD). For standard production non-Monolithic FCD, Bombardier Short Brothers SB V25MFC–71– 1003 specifies to accomplish the instructions E:\FR\FM\04MYP1.SGM 04MYP1 19649 Federal Register / Vol. 83, No. 87 / Friday, May 4, 2018 / Proposed Rules of Goodrich SB V2500–NAC–71–0331, as applicable.

FAA’s Determination and Requirements of This Proposed AD You may examine the MCAI in the AD docket on the internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0358. Related Service Information Under 1 CFR Part 51 Bombardier Short Brothers, PLC has issued Service Bulletin V25MFC–71– 1003, dated September 28, 2016. The service information describes procedures for installing modified latches on the left and right engine FCDs, and re-identifying the FCDs. This service information is reasonably 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 EASA AD 2017–0178, dated September 15, 2017, includes both monolithic FCDs and non-monolithic FCDs (those not modified by Bombardier Short Brothers, PLC Supplemental Type Certificate (STC) ST03076NY). Required actions for the non-monolithic FCDs are included in AD 2017–13–10 (which corresponds to EASA AD 2016–0053, dated March 14, 2016), so we have not included them in this AD. Costs of Compliance We estimate that this proposed AD affects 557 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Modification and re-identification (or replacement), and placard installation. 8 work-hours × $85 per hour = $680 ............. amozie on DSK3GDR082PROD with PROPOSALS Authority for This Rulemaking Regulatory Findings 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. 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.

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 2017-0178, dated September 15, 2017 (referred 
to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, 
A321-231, and A321-232 airplanes. The MCAI states:

    Fan Cowl Door (FCD) losses during take-off were reported on 
Airbus A320 family aeroplanes equipped with IAE [International Aero 
Engines] V2500 engines. Investigations confirmed that in all cases, 
the FCD were opened prior to the flight and were not correctly re-
secured. During the pre-flight inspection, it was not detected that 
the FCD were not properly latched.
    This condition, if not corrected, could lead to in-flight loss 
of an FCD, possibly resulting in damage to the aeroplane and/or 
injury to persons on the ground.
    EASA issued AD 2016-0053 [which corresponds to FAA AD 2017-13-
10, Amendment 39-18940 (82 FR 29371, June 29, 2017) (``AD 2017-13-
10'')], requiring modification of the FCD installed on affected 
aeroplanes, and installation of a placard in the cockpit, in 
accordance with the instructions of Airbus Service Bulletin (SB) 
A320-71-1069 (which in turns refers to Goodrich SB V2500-NAC-71-0331 
for FCD modification and re-identification).
    The monolithic FCDs, installed on aeroplanes embodying Short 
Brothers supplemental type certificate (STC) 10029547, are also 
affected by this potential unsafe condition. Consequently, the STC 
Holder, trading as Bombardier Short Brothers, developed a 
modification, similar to the one designed by Airbus, and issued SB 
V25MFC-71-1003. The modification consists of a new FCD front latch 
and keeper assembly, 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. The applicable Flight Crew Operating Manual has 
been amended accordingly. After modification, the FCD is identified 
with a different Part Number (P/N).
    Mixed FCD installation can be found on aeroplanes embodying 
[EASA] STC 10029547 (i.e., Monolithic FCD and standard production 
non-Monolithic FCD). For standard production non-Monolithic FCD, 
Bombardier Short Brothers SB V25MFC-71-1003 specifies to accomplish 
the instructions

[[Page 19649]]

of Goodrich SB V2500-NAC-71-0331, as applicable.
    For the reasons described above, this [EASA] AD requires 
modification and re-identification of FCD, and installation of a 
placard in the cockpit.

procedures for installing modified latches on the left and right engine 
FCDs, and re-identifying the FCDs. 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

    EASA AD 2017-0178, dated September 15, 2017, includes both 
monolithic FCDs and non-monolithic FCDs (those not modified by 
Bombardier Short Brothers, PLC Supplemental Type Certificate (STC) 
ST03076NY). Required actions for the non-monolithic FCDs are included 
in AD 2017-13-10 (which corresponds to EASA AD 2016-0053, dated March 
14, 2016), so we have not included them in this AD.

Costs of Compliance

    We estimate that this proposed AD affects 557 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES
