14 CFR Part 39

[Docket No. FAA-2013-0699; Directorate Identifier 2012-NM-198-AD; 
Amendment 39-17751; AD 2014-03-13]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This AD 
was prompted by three reports of cracking in the rear pressure bulkhead 
(RPBH) web. This AD requires inspecting the RPBH web for cracking, and 
repairing if necessary. We are issuing this AD to detect and correct 
cracking of the RPBH web, which could result in in-flight decompression 
of the airplane and possible injury to the occupants.

DATES: This AD becomes effective April 1, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 1, 
2014.

ADDRESSES: You may examine the AD on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2013-0699; or in person at the 
U.S. Department of Transportation, Docket Operations, M-30, West 
Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE.,

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 Fokker Services 
B.V. Model F.28 Mark 0070 and 0100 airplanes. The NPRM published in the 
Federal Register on August 23, 2013 (78 FR 52465). The NPRM was 
prompted by three reports of cracking in the rear pressure bulkhead 
(RPBH) web. The NPRM proposed to require inspecting the RPBH web for 
cracking, and repairing if necessary. We are issuing this AD to detect 
and correct cracking of the RPBH web, which could result in in-flight 
decompression of the airplane and possible injury to the occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0219, dated October 19, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    Three reports have been received of a crack in the rear pressure 
bulkhead (RPBH) web, just below the horizontal beam XI between 
buttock lines BL425L and BL425R, in the centre web bay below the 
pressure relief valves.
    This condition, if not detected and corrected, could result in 
an exponential crack growth rate, possibly leading to failure of the 
affected RPBH web, resulting in in-flight decompression of the 
aeroplane and possible injury to occupants.
    A repetitive inspection requirement has been published in issue 
10 of Fokker Services [Airworthiness Limitations Section] ALS Report 
SE-623 under task number 534106-00-05. The threshold to start this 
ALS-task is 30,000 [total] flight cycles (FC). However, it is known 
that many aeroplanes have already exceeded this threshold.

[[Page 10336]]

    For the reasons described above, this [EASA] AD requires a one-
time inspection [detailed visual or high frequency eddy current 
inspection] of the affected RPBH web for cracks and, depending on 
findings, accomplishment of a repair. The repair can also be applied 
at any time as a modification, thereby exempting the aeroplane from 
(further) repetitive ALS task 534106-00-05 inspections.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-0699-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 52465, August 23, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available 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 (78 FR 52465, August 23, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 52465, August 23, 2013).

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

                                       hour = $425.
----------------------------------------------------------------------------------------------------------------

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

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.

Examining the AD Docket

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2013-0699; or in person at 
the Docket Operations office between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The AD docket contains this AD, the 
MCAI, the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section.
