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 all BAE Systems 
(Operations) Limited Model BAe 146 series airplanes, and Model Avro 
146-RJ series airplanes. The NPRM published in the Federal Register on 
September 3, 2014 (79 FR 52260).
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2013-0207, dated September 9, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all BAE Systems 
(Operations) Limited Model BAe 146 series airplanes, and Model Avro 
146-RJ series airplanes. The MCAI states:

    In 2012, a pressurisation problem occurred on an AVRO 146-RJ100 
aeroplane during climb-out. Subsequent investigation results 
identified a 42.87 inch (1089 mm) long crack in the fuselage skin in 
the rear fuselage drum, near the rear passenger door. The skin crack 
had initiated in the step of the skin land adjacent to a lap joint. 
In addition to the skin crack, cracks were found in Frames 41X and 
42.
    This condition, if not detected and corrected, could lead to 
degradation of the structural integrity of the aeroplane.
    Prompted by this finding, BAE Systems (Operations) Ltd issued 
Inspection Service Bulletin (ISB) 53-239, providing instructions to 
inspect the internal area of the rear fuselage drum for cracks, 
corrosion and any other defects and EASA issued AD 2012-0178 [http://ad.easa.europa.eu/blob/easa_ad_2012_0178_Superseded.pdf/AD_2012-0178_1] which required accomplishment of a one-time inspection of 
the affected fuselage area and, depending on findings, repair of 
cracked structural items.
    Following the issuance of that [EASA] AD, some new information 
on additional damage found on the aeroplane that had the 
pressurisation problem resulted in a further review of the cracking 
event. This review concluded that the event was more serious than 
previously considered and that the compliance time must be reduced 
in order to mitigate the risk of cracking on other aeroplanes. As a 
result, EASA issued AD 2012-0184 [http://ad.easa.europa.eu/blob/easa_ad_2012_0184_superseded.pdf/AD_2012-0184_1] which superseded 
EASA AD 2012-0178.
    After analysing the responses to EASA AD 2012-0184, which 
covered the initial inspection of stringer 30, left hand (LH) and 
right hand (RH), BAE Systems (Operations) Ltd also assessed the 
similar design features at other skin lands in the rear fuselage 
drum, namely at stringer 2 right and stringers 11 and 18, LH and RH. 
As a result, they determined that inspections at the other stringers 
would be required and also that repeat inspections of all these 
stringers would be necessary. Consequently, BAE Systems (Operations) 
Ltd ISB.53-239 Revision 1 and 2 were issued to include these new 
inspections.
    For the reasons described above, this [EASA] AD retains the 
requirements of EASA AD 2012-0184, which is superseded, and requires 
accomplishment of additional inspections of the affected fuselage 
area, including repetitive inspections, and depending on findings, 
repair of cracked structural items.

    The required actions include repetitive external eddy current 
inspections on the aft skin lap joints of the rear fuselage for 
cracking, corrosion, and other defects, and repair if necessary. You 
may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0621-0002.

Actions Since Issuance of NPRM (79 FR 52260, September 3, 2014)

    Since we issued the NPRM (79 FR 52260, September 3, 2014), we have 
received BAE Systems (Operations) Limited Inspection Service Bulletin 
53-239, Revision 3, dated May 7, 2014. The new service information 
includes minor editorial changes.
    We have revised paragraph (g)(1) of this AD to refer to BAE Systems 
(Operations) Limited Inspection Service Bulletin 53-239, Revision 3, 
dated May 7, 2014. We have also revised paragraph (i) of this AD to 
provide credit for BAE Systems (Operations) Limited Inspection Service 
Bulletin 53-239, Revision 2, dated July 15, 2013.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 52260, September 3, 
2014) or on the determination of the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (79 FR 52260, September 3, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 52260, September 3, 2014).

Related Service Information Under 1 CFR Part 51

    BAE Systems (Operations) Limited has issued Inspection Service 
Bulletin 53-239, Revision 3, dated May 7, 2014. The service information 
describes an external eddy current inspection on the aft skin lap 
joints of the rear fuselage for cracking, corrosion, and other defects, 
and repair. The actions described in this service information are 
intended to correct the unsafe condition identified in the MCAI. This 
service information is reasonably available; see ADDRESSES for ways to 
access this service information.

Costs of Compliance

    We estimate that this AD affects 1 airplane of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                                     Estimated Costs

            Action                        Labor cost              Parts cost              Cost per product                  Cost on U.S. operators
--------------------------------------------------------------------------------------------------------------------------------------------------------
Inspection....................  8 work-hours x $85 per hour =              $0   $680 per inspection cycle..........  $680 per inspection cycle.
                                 $680 per inspection cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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.

Regulatory Findings

    We determined that 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.
