14 CFR Part 39

[Docket No. FAA-2010-1038; Directorate Identifier 2009-NM-250-AD; 
Amendment 39-16601; AD 2011-04-01]

Airworthiness Directives; Fokker Services B.V. Model F.28 Mark 
0070 and 0100 Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    During a normal walkaround check on a F28 Mark 0100 aeroplane, a 
large crack was discovered in the lower portion of the right (RH) 
MLG [main landing gear] piston. The affected MLG unit had 
accumulated 7909 flight cycles (FC) at the time of detection. * * *
    This condition, if not detected and corrected, could lead to MLG 
failure, possibly resulting in loss of control of the aeroplane 
during the landing roll-out.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective March 22, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 22, 
2011.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov 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., Washington, DC.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on October 21, 2010 (75 
FR 64963). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    During a normal walkaround check on a F28 Mark 0100 aeroplane, a 
large crack was discovered in the lower portion of the right (RH) 
MLG [main landing gear] piston. The affected MLG unit had 
accumulated 7909 flight cycles (FC) at the time of detection. The 
piston has been sent to Goodrich, the landing gear manufacturer, for 
detailed investigation.
    This condition, if not detected and corrected, could lead to MLG 
failure, possibly resulting in loss of control of the aeroplane 
during the landing roll-out.
    For the reasons described above, this AD requires a one-time 
detailed visual inspection of the MLG pistons, the replacement of 
any MLG pistons on which cracks are detected, and the reporting of 
all findings to the aeroplane TC [type certificate] holder. The 
inspection results, in combination with the findings of the crack/
metallurgical investigation of the cracked piston by Goodrich, will 
be used to determine the necessity of additional and/or more 
detailed inspections, or any other corrective action. This AD is 
considered an interim measure, and further action is likely to 
follow.

You may obtain further information by examining the MCAI in the AD 
docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received.

Request To Update Reference to MCAI

    The European Aviation Safety Agency (EASA) requested that we update 
the NPRM to refer to EASA AD 2009-0221R1, dated June 30, 2010. This 
EASA AD corrects a typographical error, which was the source of a 
difference between the FAA NPRM and the EASA AD.
    We agree with the EASA's request to update this final rule to refer 
to the latest EASA AD. We have also revised Note 1 of the final rule to 
state that there are no differences between the EASA AD and the FAA AD.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the

[[Page 8619]]

public interest require adopting the AD with the changes described 
previously. We determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry. 
We also estimate that it will take about 3 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 to the U.S. operators to be $1,530 or $255 per product.

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 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); and
    3. 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; 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 the NPRM, 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. Comments will be available in the AD docket shortly 
after receipt.

41060-2, 41060-3, 41060-4, 41060-5, or 41060-6.

Subject

    (d) Air Transport Association (ATA) of America Code 32: Landing 
gear.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    During a normal walkaround check on a F28 Mark 0100 aeroplane, a 
large crack was discovered in the lower portion of the right (RH) 
MLG piston. The affected MLG unit had accumulated 7909 flight cycles 
(FC) at the time of detection. The piston has been sent to Goodrich, 
the landing gear manufacturer, for detailed investigation.
    This condition, if not detected and corrected, could lead to MLG 
failure, possibly resulting in loss of control of the aeroplane 
during the landing roll-out.
    For the reasons described above, this AD requires a one-time 
detailed visual inspection of the MLG pistons, the replacement of 
any MLG pistons on which cracks are detected, and the reporting of 
all findings to the aeroplane TC [type certificate] holder. The 
inspection results, in combination with the findings of the crack/
metallurgical investigation of the cracked piston by Goodrich, will 
be used to determine the necessity of additional and/or more 
detailed inspections, or any other corrective action. This AD is 
considered an interim measure, and further action is likely to 
follow.

Compliance

    (f) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

detailed visual inspection for cracks of the MLG pistons, in 
accordance with the Accomplishment Instructions of Fokker Service 
Bulletin SBF100-32-158, dated October 2, 2009.
    (h) If any cracked MLG piston is found during the inspection 
required by paragraph (g) of this AD, before further flight replace 
the affected piston with a serviceable part, in accordance with the 
Accomplishment Instructions of Fokker Service Bulletin SBF100-32-
158, dated October 2, 2009.
    (i) At the applicable time specified in paragraph (i)(1) or 
(i)(2) of this AD, report the inspection results (including no 
findings) to Fokker Services B.V. by using the Questionnaire 
provided in Fokker Service Bulletin SBF100-32-158, dated October 2, 
2009.
    (1) If the inspection was done on or after the effective date of 
this AD: Submit the report within 30 days after the inspection.
    (2) If the inspection was done before the effective date of this 
AD: Submit the report within 30 days after the effective date of
