Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2014-20-
04, which applies to all Airbus SAS Model A318 series airplanes; Airbus 
SAS Model A319 series airplanes; Airbus SAS Model A320-111, -211, -212, 
-214, -231, -232, and -233 airplanes; and Airbus SAS Model A321-111, -
112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2014-20-04 
requires repetitive inspections for cracking of the four titanium 
angles between the belly fairing and the keel beam side panel, an 
inspection for cracking of the open holes if any cracking is found in 
the titanium angles, and repair or replacement if necessary. Since we 
issued AD 2014-20-04, we have determined that additional work is 
necessary for certain airplanes. This proposed AD would continue to 
require repetitive inspections for cracking of the four titanium angles 
between the belly fairing and the keel beam side panel, an inspection 
for cracking of the open holes if any cracking is found in the titanium 
angles, and repair or replacement if necessary. This proposed AD would 
also revise the applicability by adding Model A320-216 airplanes. This 
proposed AD would also require a detailed inspection for and 
replacement of certain rivets (including a rotating probe test for 
cracks in the open holes), and corrective actions if necessary. We are 
proposing this AD to address the unsafe condition on these products.

DATES: We must receive comments on this proposed AD by November 1, 
2018.

Discussion

    We issued AD 2014-20-04, Amendment 39-17977 (79 FR 59636,

[[Page 46906]]

October 3, 2014) (``AD 2014-20-04''), for all Airbus SAS Model A318 
series airplanes; Airbus SAS Model A319 series airplanes; Airbus SAS 
Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Airbus 
SAS Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes. AD 2014-20-04 requires repetitive inspections for cracking 
of the four titanium angles between the belly fairing and the keel beam 
side panel, an inspection for cracking of the open holes if any 
cracking is found in the titanium angles, and repair or replacement if 
necessary. AD 2014-20-04 resulted from reports of cracks at the lower 
riveting of the four titanium angles that connect the belly fairing to 
the keel beam side panels on both sides of the fuselage. We issued AD 
2014-20-04 to address cracking of the titanium angles that connect the 
belly fairing to the keel beam side panels on both sides of the 
fuselage, which could affect the structural integrity of the airplane.

Actions Since AD 2014-20-04 Was Issued

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0091, dated April 20, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318 series 
airplanes; Airbus SAS Model A319 series airplanes; Airbus SAS Model 
A320-211, -212, -214, -216, -231, -232, and -233 airplanes; and Airbus 
SAS Model A321-111, -112, -131, -211, -212, -213, -231, and -232 
airplanes. The MCAI states:

    During the fatigue test campaign of the A320 family type design, 
cracks were found at the lower riveting of the four titanium angles 
which connect the belly fairing to the keel beam side panels between 
frames FR40 and FR42, on both sides of the fuselage.
    This condition, if not detected and corrected, could affect the 
structural integrity of the aeroplane.
    To address this potential unsafe condition, Airbus issued 
Service Bulletin (SB) A320-53-1014, and DGAC [Direction 
G[eacute]n[eacute]rale de l'Aviation Civile] France issued AD 92-
201-030 [which corresponds to FAA AD 94-12-03, Amendment 39-8930 (59 
FR 28763, June 3, 1994)(``AD 94-12-03'')] to require reinforcement 
of the belly fairing structure.
    Following new investigation which showed that these measures 
addressed only part of the unsafe condition, Airbus published SB 
A320-53-1259 and EASA issued AD 2013-0122 [which corresponds to FAA 
AD 2014-20-04], retaining the requirements of DGAC France AD 92-201-
030, which was superseded, and requiring repetitive detailed 
inspections (DET) of the affected titanium angles and, depending on 
findings, repair or replacement of parts.
    After that [EASA] AD was issued, Airbus published Revision 
(Rev.) 01 and Rev. 02 of SB A320-53-1259. [Airbus SB A320-53-1259] 
Rev. 02 provided incorrect instructions to use Part Number (P/N) 
EN6081D4 rivets for the titanium angles installation, instead of P/N 
EN6081D5 rivets. Consequently, Airbus SB A320-53-1259 was updated 
(now at Rev. 03) including reference to the proper rivets.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2013-0122, which is superseded, and requires 
additional work [a detailed inspection for and replacement of 
certain rivets, and applicable corrective actions] for aeroplanes on 
which Airbus SB A320-53-1259 at Rev. 02 was embodied.

    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-
0795.

Model A320-216 Airplanes

    The Airbus SAS Model A320-216 was type certificated on December 19, 
2016. Before that date, any EASA ADs that affected Model A320-216 
airplanes were included on the Required Airworthiness Actions List 
(RAAL). One or more Model A320-216 airplanes have subsequently been 
placed on the U.S. Register, and will now be included in FAA AD 
actions. For Model A320-216 airplanes, the requirements that correspond 
to AD 2014-20-04 were mandated by the MCAI via the RAAL. Although that 
RAAL requirement is still in effect, for continuity and clarity we have 
identified Model A320-216 airplanes in paragraph (c) of this AD; the 
restated requirements of paragraphs (h) through (n) in this proposed AD 
would therefore apply to those airplanes.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Service Bulletin A320-53-1259, Revision 03, 
dated November 30, 2017. This service information describes procedures 
for repetitive inspections for cracking of the four titanium angles 
between the belly fairing and the keel beam side panel, an inspection 
for cracking of the open holes if any cracking is found in the titanium 
angles, repair or replacement if necessary, and a detailed inspection 
for and replacement of certain rivets (including a rotating probe test 
for cracks in the open holes).
    Airbus also issued Service Bulletin A320-53-1014, Revision 2, dated 
September 1, 1994. This service information describes procedures for 
reinforcement (modification) of the belly fairing structure.
    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

    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 the relevant information and determined the unsafe 
condition described previously is likely to exist or develop on other 
products of the same type design.

Proposed Requirements of This NPRM

    This proposed AD would retain all requirements of AD 2014-20-04. 
This proposed AD would also require accomplishing the actions specified 
in the service information described previously.

Costs of Compliance

    We estimate that this proposed AD affects 1,250 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
           Labor cost              Parts cost            Cost per product              Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
295 work-hours x $85 per hour =          $1,045  $26,120.........................  $32,650,000.
 $25,075 (Old actions of AD
 2014-20-04).
Up to 168 work-hours x $85 per                0  Up to $14,280...................  Up to $17,850,000.
 hour = Up to $14,280 (New
 actions of this AD).
----------------------------------------------------------------------------------------------------------------


[[Page 46907]]

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

                 Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                  Parts cost *       product
------------------------------------------------------------------------
168 work-hours x $85 per hour =                     $0          $14,280
 $14,280..............................
------------------------------------------------------------------------
* We have received no definitive data that would enable us to provide
  cost estimates for the on-condition parts 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.
    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.
