Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2008-05-
18 R1 for certain Fokker Services B.V. Model F.27 Mark 050, 200, 300, 
400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 currently requires 
revising the Airworthiness Limitations Section (ALS) of the 
Instructions for Continued Airworthiness to incorporate new limitations 
for fuel tank systems. Since we issued AD 2008-05-18 R1, revised 
service information has been issued to update the Fuel Airworthiness 
Limitations Items (ALIs) and critical design configuration control 
limitations (CDCCLs) that address fuel tank system ignition sources. 
This proposed AD would require a new maintenance or inspection program 
revision to incorporate the revised ALIs and CDCCLs. This proposed AD 
would add certain airplanes to the applicability. We are proposing this 
AD to prevent the potential of ignition sources inside fuel tanks, 
which, in combination with flammable fuel vapors, could result in fuel 
tank explosions and consequent loss of the airplane.

DATES: We must receive comments on this proposed AD by February 18, 
2016.

Discussion

    On October 26, 2009, we issued AD 2008-05-18 R1, Amendment 39-16083 
(74 FR 57402, November 6, 2009) for certain Model F.27 Mark 050, 200, 
300, 400, 500, 600, and 700 airplanes. AD 2008-05-18 R1 requires 
revising the Airworthiness Limitations Section (ALS) of the 
Instructions for Continued Airworthiness to incorporate new limitations 
for fuel tank systems.
    Since we issued AD 2008-05-18 R1, Amendment 39-16083 (74 FR 57402, 
November 6, 2009), revised service information has been issued to 
update the fuel ALIs and CDCCLs. The revised service information 
applies to all Model F.27 Mark 200, 300, 400, 500, 600, and 700 
airplanes.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0029, dated February 24, 2015 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Fokker Services 
B.V. Model F.27 Mark 200, 300, 400, 500, 600, and 700 airplanes. The 
MCAI states:

    * * * [T]he FAA published Special Federal Aviation Regulation 
(SFAR) 88, and the Joint Aviation Authorities (JAA) published 
Interim Policy INT/POL/25/12. The review conducted by Fokker 
Services on the Fokker F27 design in response to these regulations 
identified a number of Fuel Airworthiness Limitation Items (ALI) and 
Critical Design Configuration Control Limitations (CDCCL) items to 
prevent the development of unsafe conditions within the fuel system.
    To introduce these Fuel ALI and CDCCL items, Fokker Services 
published Service Bulletin (SB) F27/28-070. Consequently, EASA 
issued AD 2006-0207, requiring the implementation of these Fuel ALI 
and CDCCL items. That [EASA] AD was later revised to make reference 
to SBF27-28-070R1 and to specify that the use of later SB revisions 
was acceptable.
    In 2014, Fokker Services issued Revision 2 of SBF27-28-070 to 
update the Fuel ALI and CDCCL items and to consolidate Fuel ALI and 
CDCCL items contained in a number of other SBs. Consequently, EASA 
issued AD 2014-0105, superseding AD 2006-0207R1 and requiring the 
implementation of the updated Fuel ALI and CDCCL items.
    Since that [EASA] AD was issued, Fokker Services issued Revision 
3 of SBF27-28-070, primarily to introduce 2 additional CDCCL items.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2014-0105, which is superseded, and requires 
implementation of the updated Fuel ALI and CDCCL items.
    More information on this subject can be found in Fokker Services 
All Operators Message AOF27.043#05.

The unsafe condition is the potential of ignition sources inside fuel 
tanks. Such ignition sources, in combination with flammable fuel 
vapors, could result in fuel tank explosions and consequent loss of the 
airplane. You may examine the MCAI in the AD docket on the

[[Page 39]]

Internet at http://www.regulations.gov by searching for and locating it 
in Docket No. FAA-2015-8137.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Service Bulletin SBF27-28-070, 
Revision 3, dated December 11, 2014. The service information describes 
tasks for revising the maintenance or inspection program to update the 
fuel ALIs and CDCCLs that address fuel tank system ignition sources. 
This service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section of this NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.
    This proposed AD would require implementation of certain 
maintenance requirements and airworthiness limitations. This proposed 
AD would also require accomplishing the actions specified in the 
service information described previously.
    This proposed AD would require revisions to certain operator 
maintenance documents to include new actions (e.g., inspections) and 
CDCCLs. Compliance with these actions and CDCCLs is required by 14 CFR 
91.403(c). For airplanes that have been previously modified, altered, 
or repaired in the areas addressed by these actions, 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 according to 
the procedures specified in paragraph (m)(1) of this AD. The request 
should include a description of changes to the required actions that 
will ensure the continued operational safety of the airplane.
    Notwithstanding any other maintenance or operational requirements, 
components that have been identified as airworthy or installed on the 
affected airplanes before accomplishing the revision of the airplane 
maintenance or inspection program, or before accomplishing the revision 
of the Airworthiness Limitation Section (ALS) of the Instructions for 
Continued Airworthiness, as specified in this AD, do not need to be 
reworked in accordance with the CDCCLs. However, once the airplane 
maintenance or inspection program, or ALS, has been revised as required 
by this AD, future maintenance actions on these components must be done 
in accordance with the CDCCLs

Costs of Compliance

    We estimate that this proposed AD affects 16 airplanes of U.S. 
registry.
    The actions that are required by AD 2008-05-18 R1, Amendment 39-
16083 (74 FR 57402, November 6, 2009), take about 1 work-hour per 
product, at an average labor rate of $85 per work-hour. Required parts 
cost about $0 per product. Based on these figures, the estimated cost 
of the actions required by AD 2008-05-18 R1 is $85 per product.
    We also estimate that it would take about 1 work-hour per product 
to comply with the new basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $0 per product. Based on these figures, we estimate the cost of 
this proposed AD on U.S. operators to be $1,360, or $85 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    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.
