SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus SAS Model 
A319-131, A319-132, A319-133, A320-231, A320-232, A320-233, A321-131, 
A321-231, and A321-232 airplanes. The NPRM published in the Federal 
Register on May 4, 2018 (83 FR 19648). The NPRM was prompted by reports 
of FCD losses during take-off. The NPRM proposed to require 
modification and re-identification, or replacement, of certain FCDs, 
and installation of a placard in the flight deck.
    We are issuing this AD to address in-flight loss of an FCD, which 
could result in damage to the airplane and injury to persons on the 
ground.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
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 SAS 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 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.

    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-2018-
0358.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Support for the NPRM

    The Air Line Pilots Association, International (ALPA) supported the 
NPRM.

Request To Extend Compliance Time

    United Airlines (UAL) requested that the compliance time stated in 
the proposed AD be extended from 18 months to 36 months to match the 
compliance time stated in AD 2017-13-10. UAL noted that both the 
proposed AD and AD 2017-13-10 address the same unsafe condition, but on 
different FCDs. UAL added that it has a mixture of FCD configurations, 
which will be subject to different compliance times.
    We disagree with the commenter's request to extend the compliance 
time to 36 months. We based the compliance time for this AD on the 
compliance time required by the EASA MCAI, which was determined by 
considering the urgency associated with the unsafe condition, the 
availability of required parts, and the practical aspect of 
accomplishing the required modification within a timeframe that 
corresponds to the normal scheduled maintenance for most affected 
operators. In addition, the manufacturer recommended that the service 
bulletin be accomplished no later than March 28, 2019. We have not 
changed this AD in this regard.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this final rule as proposed with 
the changes described previously and minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

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 available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section.

Costs of Compliance

    We estimate that this AD affects 557 airplanes of U.S. registry. We 
estimate the following costs to comply with this 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 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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.
