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 A319-131, -132, and -133 airplanes; Model A320-232 and -
233 airplanes; and Model A321-131, -231, and -232 airplanes. This 
proposed AD was prompted by reports of forward engine mount attachment 
pins that were manufactured from discrepant raw material. This proposed 
AD would require identification and replacement of affected forward 
engine mount attachment pins. We are proposing this AD to prevent 
failure of a forward engine mount attachment pin, possible loss of an 
engine in-flight, and consequent reduced controllability of the 
airplane.

DATES: We must receive comments on this proposed AD by September 14, 
2015.

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 2015-0004, dated January 13, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A319-131, -132, and -133 airplanes; Model A320-232 and -233 airplanes; 
and Model A321-131, -231, and -232 airplanes. The MCAI states:

    A number of forward engine mount pins, Part Number (P/N) 740-
2022-501, intended for IAE V2500 series engines, have been reported 
as non-compliant with the current certification requirements, due to 
a quality issue during manufacturing of the raw material. It was 
also determined that a batch of 88 affected pins are installed on 
in-service aeroplanes fitted with forward engine mount P/N 745-2010-
503 and the serial numbers (s/n) of the affected pins and the 
[manufacturer serial number] MSN of the related aeroplanes have been 
identified.
    This condition, if not corrected, could lead to forward engine 
mount pin failure, possibly resulting in in-flight loss of an engine 
and consequent reduced control of the aeroplane.
    For the reasons described above, this [EASA] AD requires 
identification of the affected forward engine mount pins and removal 
from service [replacement] of those pins.

    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-
2963.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-71-1064, dated November 5, 
2014; and Goodrich Aerostructures has issued Service Bulletin V2500-
NAC-71-0323, dated September 18, 2014. The service information 
describes procedures for an inspection to determine the serial number 
of the attachment pins for the forward engine mount crossbeam to main 
beam for each engine, and replacement of affected pins. 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.

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.

Explanation of ``RC'' Procedures and Tests 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 procedures and tests in the service information are 
required for compliance with an AD. Differentiating these procedures 
and tests 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 procedures 
and tests identified as RC (required for compliance) in any service 
information have a direct effect on detecting, preventing, resolving, 
or eliminating an identified unsafe condition.
    As specified in a NOTE under the Accomplishment Instructions of the 
specified Airbus service information, procedures and tests identified 
as RC must be done to comply with the proposed AD. However, procedures 
and tests that are not identified as RC are recommended. Those 
procedures and tests 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 procedures and tests identified as 
RC can be done and the airplane can be put back in a serviceable 
condition. Any substitutions or changes to procedures or tests 
identified as RC will require approval of an AMOC.

Costs of Compliance

    We estimate that this proposed AD affects 922 airplanes of U.S. 
registry.
    We also estimate that it would take about 2 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $156,740, or $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 4 work-hours and require parts costing $1,724, for a cost of 
$2,064 per attachment pin replacement. We have no way of determining 
the number of aircraft that might need this action.

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.

directive (AD):

Airbus: Docket No. FAA-2015-2963; Directorate Identifier 2015-NM-
016-AD.

(a) Comments Due Date

    We must receive comments by September 14, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the Airbus airplanes identified in paragraphs 
(c)(1), (c)(2), and (c)(3) of this AD, certificated in any category, 
all manufacturer serial numbers.
    (1) Model A319-131, -132, and -133 airplanes.
    (2) Model A320-232 and -233 airplanes.
    (3) Model A321-131, -231, and -232 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 71, Power Plant.

(e) Reason

    This AD was prompted by reports of forward engine mount 
attachment pins that were manufactured from discrepant raw material. 
We are issuing this AD to prevent failure of a forward engine mount 
attachment pin, possible loss of an engine in-flight, and consequent 
reduced controllability of the airplane.

(f) Compliance

unless already done.

(g) Identification of Part Numbers for Forward Engine Mount and 
Attachment Pins

    Except as provided by paragraph (i) of this AD, at the earliest 
of the times specified in paragraphs (g)(1) through (g)(4) of this 
AD: For each engine, identify the part number of the forward engine 
mount, and the part number and serial number of the attachment pin 
for that forward engine mount, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A320-71-1064, dated November 
5, 2014; and Goodrich Aerostructures Service Bulletin V2500-NAC-71-
0323, dated September 18, 2014. A review of airplane maintenance 
records is acceptable in lieu of this identification if the part 
number of the forward engine mount, and the part number and serial 
number of the attachment pin for that forward engine mount can be 
conclusively determined from that review. If any part number of the 
forward engine mount, or part number or serial number of the 
attachment pins for the forward engine mount, cannot be identified: 
At the earliest of the times specified in paragraphs (g)(1) through 
(g)(4) of this AD, contact the Manager, International Branch, ANM-
116, Transport Airplane Directorate, FAA; or the European Aviation 
Safety Agency (EASA); or Airbus's EASA Design Organization Approval 
(DOA), for identification information.
    (1) Within 24 months after the effective date of this AD.
    (2) At the next engine removal after the effective date of this 
AD.
    (3) Within 7,500 flight hours after the effective date of this 
AD.
    (4) Within 5,000 flight cycles after the effective date of this 
AD.

(h) Corrective Actions

    If, during any identification required by paragraph (g) of this 
AD, a forward engine mount having part number (P/N) 745-2010-503 is 
found, and the attachment pin has P/N 740-2022-501 with any serial 
number that is included in figure 1 to paragraphs (h) and (j) of 
this AD: At the earliest of the times specified in paragraphs (g)(1) 
through (g)(4) of this AD, replace the affected attachment pin with 
a serviceable part having a part number other than P/N 740-2022-501, 
and having a serial number that is not identified in figure 1 to 
paragraphs (h) and (j) of this AD, in accordance with the 
Accomplishment Instructions of Airbus Service Bulletin A320-71-1064, 
dated November 5, 2014; and Goodrich Aerostructures Service Bulletin 
V2500-NAC-71-0323, dated September 18, 2014.

(j) Parts Installation Prohibition

    As of the effective date of this AD, no person may install on 
any airplane any engine mount attachment pin having P/N 740-2022-501 
with a serial number identified in figure 1 to paragraphs (h) and 
(j) of this AD.

(k) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, 
International Branch, ANM-116, Transport Airplane Directorate, FAA, 
has the authority to approve AMOCs for this AD, if requested using 
the procedures found in 14 CFR 39.19. In accordance with 14 CFR 
39.19, send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the International Branch, send it to ATTN: Sanjay 
Ralhan, Aerospace Engineer, International Branch, ANM-116, Transport 
Airplane Directorate, FAA, 1601 Lind Avenue SW., Renton, WA 98057-
3356; telephone 425-227-1405; fax 425-227-1149. Information may be 
emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office. The 
AMOC approval letter must specifically reference this AD.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, International 
Branch, ANM-116, Transport Airplane Directorate, FAA; or the EASA; 
or Airbus's EASA DOA. If approved by the DOA, the approval must 
include the DOA-authorized signature.
    (3) Required for Compliance (RC): If any service information 
contains procedures or tests that are identified as RC, those 
procedures and tests must be done to comply with this AD; any 
procedures or tests that are not identified as RC are recommended. 
Those procedures and tests 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 AMOC, provided the procedures and tests identified as 
RC can be done and the airplane can be put back in a serviceable 
condition. Any substitutions or changes to procedures or tests 
identified as RC require approval of an AMOC.

(l) Special Flight Permits Prohibited

    Special flight permits, as described in Section 21.197 and 
Section 21.199 of the Federal Aviation Regulations (14 CFR 21.197 
and 21.199), are not allowed.
