14 CFR Part 39

[Docket No. FAA-2015-0826; Directorate Identifier 2014-NM-221-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 
certain Airbus Model A318, A319, and A320 series airplanes modified by 
a particular supplemental type certificate (STC). This proposed AD was 
prompted by reports of cracks found during inspections of the in-flight 
entertainment system radome assembly. This proposed AD would require 
repetitive detailed inspections for cracks in the radome assembly, and 
replacement of the radome if necessary. We are proposing this AD to 
detect and correct cracks in the radome assembly, which could result in 
the radome (or pieces) separating from the airplane and striking the 
tail, consequently reducing the controllability of the airplane.

DATES: We must receive comments on this proposed AD by June 1, 2015.

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

Discussion

    We received reports of cracks in the in-flight entertainment system 
radomes of certain Airbus airplanes. The cracks were found during 
inspections of the radome assembly on various Airbus Model A318, A319, 
and A320 series airplanes that had in-flight entertainment systems 
installed using a certain STC issued to Live TV (STC number STC 
ST00788SE, http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/6df40775b10ef09a86257ae200613cfe/$FILE/ST00788SE.pdf). 
Investigation of the cause of the cracks revealed that radome 
manufacturing variation, due to a lack of dimensional

[[Page 20176]]

controls on the radome manufacturing drawings, can result in the 
introduction of preload stress on the radome during its assembly with 
the skirt fairing. Preload stress combined with flight or handling 
stress, such as maintenance personnel stepping on the radome fairing 
assembly, might initiate a crack. The radome manufacturing drawings 
were revised on September 13, 2010, to add a control dimension, which 
was incorporated into production at radome serial number 498. Cracks in 
the radome, if not corrected, could result in the radome (or pieces) 
separating from the airplane and striking the tail, consequently 
reducing the controllability of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Live TV Service Bulletin A320-53-006, Rev 01, dated 
September 10, 2014. The service information describes procedures for 
repetitive detailed inspections for cracks in the outer ply of the 
radome, and replacement of the radome with a new or serviceable radome, 
if any crack is found. This service information is reasonably 
available; see ADDRESSES for ways to access this service information.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would require accomplishing the actions specified 
in the service information described previously. In addition, if any 
crack is found in a radome during an inspection, this proposed AD would 
require sending the inspection results to Live TV.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a new process for 
annotating which steps in the service information are required for 
compliance with an AD. Differentiating these steps from other tasks in 
the service information is expected to improve an owner's/operator's 
understanding of crucial AD requirements and help provide consistent 
judgment in AD compliance. The steps identified as RC (required for 
compliance) in any service information identified previously have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.
    Steps that are identified as RC in any service information must be 
done to comply with the proposed AD. However, steps that are not 
identified as RC are recommended. Those steps that are not identified 
as RC may be deviated from using accepted methods in accordance with 
the operator's maintenance or inspection program without obtaining 
approval of an alternative method of compliance (AMOC), provided the 
steps identified as RC can be done and the airplane can be put back in 
a serviceable condition. Any substitutions or changes to steps 
identified as RC will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 120 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
              Action                    Labor cost        Parts cost     Cost per product         operators

                                    inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed 
inspections. We have no way of determining the number of aircraft that 
might need this replacement:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------

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 AD is 2120-
0056. The paperwork cost associated with this 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 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.

[[Page 20177]]

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.
