14 CFR Part 39

[Docket No. FAA-2013-0865; Directorate Identifier 2012-NM-199-AD; 
Amendment 39-17819; AD 2014-07-05]

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 an evaluation by the design approval holder (DAH) 
indicating that the butt-joints on the forward fuselage above the 
passenger door are subject to widespread fatigue damage (WFD). This AD 
requires inspecting the forward fuselage butt-joints for cracking, 
repairing any crack, and eventually doing a terminating repair. We are 
issuing this AD to prevent fatigue cracking of such butt-joints, which 
could result in reduced structural integrity of the airplane and in-
flight decompression of the airplane.

DATES: This AD becomes effective May 21, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of May 21, 2014.

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 October 23, 2013 (78 FR 63132). The NPRM was 
prompted by an evaluation by the DAH indicating that the butt-joints on 
the forward fuselage above the passenger door are subject to WFD. The 
NPRM proposed to require inspecting the forward fuselage butt-joints 
for cracking, repairing any crack, and eventually doing a terminating 
repair. We are issuing this AD to prevent fatigue cracking of such 
butt-joints, which could result in reduced structural integrity of the 
airplane and in-flight decompression of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0218, 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:

    A report has been received of a crack, detected in a butt-joint 
on the forward

[[Page 21390]]

fuselage of an F28 Mark 0100 aeroplane, above the passenger door. 
Investigation results revealed that, depending on the configuration 
of the aeroplane, four butt joints in the forward fuselage can be 
affected, at stringers 8, 37, 42 and 67 between fuselage stations 
3850 and 5305.
    This condition, if not detected and corrected, can result in an 
exponential crack growth rate, possibly leading to failure of the 
butt-joint over a certain length and consequent in-flight 
decompression of the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time inspection [low frequency eddy current] of the forward fuselage 
butt joints for cracks and, depending on findings, accomplishment of 
a temporary repair [including a detailed inspection for cracks in 
the butt strap on the inside of the applicable joint, and corrective 
actions if necessary] and reporting the findings to Fokker Services. 
In addition, this AD requires a permanent repair/modification [and a 
detailed inspection for cracks in the butt strap on the inside of 
the applicable joint, and corrective actions if necessary].

    Corrective actions include removing the cracked part of the butt 
joint and installing an insert, and installing of an external repair 
strap. You may examine the MCAI in the AD docket on the Internet at 
http://www.regulations.gov/#!documentDetail;D=FAA-2013-0865-0001.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 63132, October 23, 
2013) 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 (78 FR 63132, October 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 63132, October 23, 2013).

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We also estimate that it will take about 127 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $43,180, or $10,795 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 30 work-hours, for a cost of $2,550 per product. We have no 
way of determining the number of aircraft that might need these 
actions.

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.

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.
