Airworthiness Directives; Fokker Services B.V. Model F.27 Mark
050, 200, 300, 400, 500, 600, and 700 Airplanes; and Model F.28
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:
[T]he Federal Aviation Administration (FAA) has published
Special Federal Aviation Regulation (SFAR) 88, and the Joint
Aviation Authorities (JAA) has published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and
F28 type designs in response to these regulations revealed that,
under certain failure conditions, a short circuit can develop in the
fuel pilot valve solenoid or in the wiring to the solenoid. Such a
short circuit may result in an ignition source in the wing tank
vapour space.
This condition, if not corrected, could result in a wing fuel
tank explosion and consequent loss of the aeroplane.
* * * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective November 16, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 16,
2011.

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 June 21, 2011 (76 FR
36011). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
[T]he Federal Aviation Administration (FAA) has published
Special Federal Aviation Regulation (SFAR) 88, and the Joint
Aviation Authorities (JAA) has published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and
F28 type designs in response to these regulations revealed that,
under certain failure conditions, a short circuit can develop in the
fuel pilot valve solenoid or in the wiring to the solenoid. Such a
short circuit may result in an ignition source in the wing tank
vapour space.
This condition, if not corrected, could result in a wing fuel
tank explosion and consequent loss of the aeroplane.
For the reasons described above, this AD requires [re-working
the wiring and] the installation of a fuse packed in a jiffy
junction [i.e., crimped wire in-line junction device] in the wiring
to the fuel pilot valve solenoid.
The required actions also include revising the maintenance program to
include a certain Critical Design Configuration Control Limitation
(CDCCL). 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 received no comments on the NPRM (76 FR 36011, June 21,
2011) 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 the AD as proposed.
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 6 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost up to $2,198 per
product. Where the service information lists required parts costs that
are covered under warranty, we have assumed that there will be no
charge for these parts. As we do not control warranty coverage for
affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of this AD to the
U.S. operators up to $16,248, or up to $2,708 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 (76 FR 36011, June 21, 2011),
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2011-21-01 Fokker Services B.V.: Amendment 39-16824. Docket No. FAA-
2011-0568; Directorate Identifier 2011-NM-010-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
16, 2011.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Fokker Services B.V. Model F.27 Mark 050,
200, 300, 400, 500,
[[Page 63158]]
600, and 700 airplanes; and Fokker Services B.V. Model F.28 Mark
0070, 0100, 1000, 2000, 3000, and 4000 airplanes; certificated in
any category; all serial numbers.
Note 1: This AD requires revisions to certain operator
maintenance documents to include a new Critical Design Configuration
Control Limitation (CDCCL). Compliance with this CDCCL is required
by 14 CFR 91.403(c). For airplanes that have been previously
modified, altered, or repaired in the areas addressed by this AD,
the operator may not be able to accomplish the actions described in
the revisions. In this situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an alternative method of
compliance (AMOC) according to paragraph (j)(1) of this AD. The
request should include a description of changes to the required
inspections that will ensure the continued operational safety of the
airplane.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
[T]he Federal Aviation Administration (FAA) has published
Special Federal Aviation Regulation (SFAR) 88, and the Joint
Aviation Authorities (JAA) have published Interim Policy INT/POL/25/
12. The review conducted by Fokker Services on the Fokker F27 and
F28 type designs in response to these regulations revealed that,
under certain failure conditions, a short circuit can develop in the
fuel pilot valve solenoid or in the wiring to the solenoid. Such a
short circuit may result in an ignition source in the wing tank
vapour space.
This condition, if not corrected, could result in a wing fuel
tank explosion and consequent loss of the aeroplane.
* * * * *
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.
Installation of Fuses Packed in Jiffy Junctions
(g) Within 24 months after the effective date of this AD, re-
work the wiring and install the fuses packed in jiffy junctions
(i.e., crimped wire in-line junction device), in accordance with the

------------------------------------------------------------------------
Critical Design Configuration Control Limitation (CDCCL)
(h) Before further flight after doing the actions required by
paragraph (g) of this AD: Revise the aircraft maintenance program by
incorporating the CDCCL specified in paragraph 1.L.(1)(c) of the
applicable Fokker service bulletins identified in table 1 of this
AD.
No Alternative Actions, Intervals, and/or CDCCLs
(i) After accomplishing the revision required by paragraph (h)
of this AD, no alternative CDCCLs may be used unless the CDCCLs are
approved as an alternative method of compliance (AMOC) in accordance
with the procedures specified in paragraph (j)(1) of this AD.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service
information as follows:
Although European Aviation Safety Agency (EASA) Airworthiness
Directive 2010-0195, dated September 29, 2010, specifies revising
the maintenance program to include maintaining CDCCLs, this AD only
requires the revision. Requiring a revision of the maintenance
program, rather than requiring maintaining CDCCLs, requires
operators to record AD compliance only at the time the revision is
made. Maintaining CDCCLs specified in the airworthiness limitations
must be complied with in accordance with 14 CFR 91.403(c).
Other FAA AD Provisions
(j) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance: The Manager,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
has the authority to approve AMOCs for this AD, if requested using
the procedures found in 14 CFR 39.19. In accordance with 14 CFR
39.19, send your request to your principal inspector or local Flight
Standards District Office, as appropriate. If sending information
directly to the International Branch, send it to ATTN: Tom
Rodriguez, Aerospace Engineer, International Branch, ANM-116,
Transport Airplane Directorate, FAA 1601 Lind Avenue, SW., Renton,
Washington 98057-3356; telephone 425-227-1137; fax 425-227-1149.
Information may be e-mailed to: [email protected].
Before using any approved AMOC, notify your appropriate principal
inspector, or lacking a principal inspector, the manager of the
local flight standards district office/certificate holding district
office. The AMOC approval letter must specifically reference this
AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
