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 all 
Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 
airplanes. This AD was prompted by a design review that revealed 
insufficient measures were taken to ensure the correct locking of the 
attachments of the fuel quantity tank units (FQTUs) in each wing tank. 
When an FQTU becomes loose, this could lead to insufficient clearance 
between the FQTU and the adjacent tank structure or other metal parts, 
and under certain conditions, create an ignition source inside the wing 
fuel vapor space. This AD requires modifying the FQTUs by applying 
sealant to cover the nuts, washers, and stud ends at the FQTU 
attachments in each main wing tank. This AD also requires revising the 
maintenance or inspection program, as applicable, by incorporating a 
fuel airworthiness limitation item and a critical design configuration 
control limitation (CDCCL). We are issuing this AD to prevent an 
ignition source in the wing fuel tank vapor space, which could result 
in a wing fuel tank explosion and consequent loss of the airplane.

DATES: This AD is effective September 8, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 8, 
2016.

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 all Fokker Services B.V. 
Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. The NPRM 
published in the Federal Register on January 20, 2016 (81 FR 3056) 
(``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0106, dated May 7, 2014 (referred to after 
this the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition for all Fokker Services B.V. 
Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. The MCAI states:

    Prompted by an accident * * *, the Federal Aviation 
Administration (FAA) published Special Federal Aviation Regulation 
(SFAR) 88 [(66 FR 23086, May 7, 2001)], and the Joint Aviation 
Authorities (JAA) published Interim Policy INT/POL/25/12.
    The review conducted by Fokker Services on the Fokker F28 
design, in response to these regulations, revealed that insufficient 
measures were taken to ensure the correct locking of the attachments 
of the Fuel Quantity Tank Units (FQTUs). When a FQTU becomes loose, 
this could lead to insufficient clearance between the FQTU and the 
adjacent tank structure or other metal parts and, under certain 
conditions, create an ignition source inside the wing fuel tank 
vapour space.
    This condition, if not detected and corrected, could result in a 
wing fuel tank explosion and consequent loss of the aeroplane.
    To address this potential unsafe condition, Fokker Services 
developed a modification to ensure that each FQTU remains properly 
attached.
    For the reasons described above, this [EASA] AD requires the 
application of sealant covering the nuts, washers and stud ends at 
the FQTU attachment in each wing tank [and a revision to the 
maintenance or inspection program, as applicable, to incorporate a 
fuel airworthiness limitation item and a CDCCL]. More information on 
this subject can be found in Fokker Services All Operators Message 
AOF28.038#02.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
8469.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

[[Page 51329]]

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the changes described 
previously and minor editorial changes. We have determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

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.

unless already done.

(g) Modification of the FQTUs

    At the next scheduled opening of the fuel tanks after the 
effective date of this AD, but no later than 84 months after the 
effective date of this AD, modify the FQTU in each main wing tank by 
applying sealant to cover the nuts, washers, and stud ends of the 
FQTU attachments, and do an inspection for leakage of the tank 
access panels, in accordance with the Accomplishment Instructions of 
Fokker Service Bulletin SBF28-28-054, Revision 1, dated January 9, 
2014; and the information in Fokker Manual Change Notification--
