14 CFR Part 39

[Docket No. FAA-2015-8138; Directorate Identifier 2014-NM-112-AD; 
Amendment 39-18552; AD 2016-12-03]
RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2011-17-10, 
for all Fokker Services B.V. Model F.28 Mark 1000, 2000, 3000, and 4000 
airplanes. AD 2011-17-10 required inspecting for a by-pass wire between 
the housing of each in-tank fuel quantity indication (FQI) cable plug 
and the cable shield, and corrective actions if necessary. AD 2011-17-
10 also required revising the airplane maintenance program. This new AD 
removes certain airplanes from the applicability. This new AD applies 
only to Model F.28 Mark 1000 airplanes and also requires revising the 
airplane maintenance or inspection program by incorporating the 
instructions in revised service information. This AD was prompted by 
the issuance of revised service information to update the critical 
design configuration control limitations (CDCCLs) that address 
potential ignition sources inside fuel tanks. We are issuing this AD to 
prevent potential ignition sources inside the fuel tanks, which, in 
combination with flammable fuel vapors, could result in fuel tank 
explosions and consequent loss of the airplane.

DATES: This AD becomes effective July 15, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of July 15, 
2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of 
September 16, 2011 (76 FR 50111, August 12, 2011).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2011-17-10, Amendment 39-16774 (76 FR 50111, 
August 12, 2011) (``AD 2011-17-10''). AD 2011-17-10 applied to all 
Model F.28 Mark 1000, 2000, 3000, and 4000 airplanes. The NPRM 
published in the Federal Register on January 4, 2016 (81 FR 34) (``the 
NPRM''). The NPRM was prompted by the issuance of revised service 
information to update the CDCCLs that address potential ignition 
sources inside fuel tanks. The NPRM proposed to retain the requirements 
of AD 2011-17-10, and to require revising the airplane maintenance or 
inspection program by incorporating the instructions in the revised 
service information. The NPRM also proposed to remove certain airplanes 
from the applicability. We are issuing this AD to prevent potential 
ignition sources inside the fuel tanks, which, in combination with 
flammable fuel vapors, could result in fuel tank explosions and 
consequent loss of the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0111, dated May 8, 2014 (referred to after 
this as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition on certain Model F.28 Mark 1000 
airplanes. The MCAI states:

    [T]he FAA published Special Federal Aviation Regulation (SFAR) 
88 [Amendment 21-78 (66 FR 23086, May 7, 2001). Subsequently, SFAR 
88 was amended by: Amendment 21-82 (67 FR 57490, September 10, 2002; 
corrected at 67 FR 70809, November 26, 2002) and Amendment 21-83 (67 
FR 72830, December 9, 2002; corrected at 68 FR 37735, June 25, 2003, 
to change ``21-82'' to ``21-83'')], and the Joint Aviation 
Authorities (JAA) published Interim Policy INT/POL/25/12.
    The review conducted by Fokker Services on the F28 design, in 
response to these regulations, revealed that on certain aeroplanes, 
an interrupted shield contact may exist or develop between the 
housing of an in-tank Fuel Quantity Indication (FQI) cable plug and 
the cable shield of the shielded FQI system cables in the main and 
collector fuel tanks, which can, under certain conditions, form a 
spark gap.
    This condition, if not detected and corrected, may create an 
ignition source in the fuel tank vapour space, possibly resulting in 
a wing fuel tank explosion and consequent loss of the aeroplane.
    To address and correct this unsafe condition, Fokker Services 
published Service Bulletin (SB) SBF28-28-053 which provides 
instructions, for early production aeroplanes, for a one-time 
inspection to check for the presence of a by-pass wire between the 
housing of each in-tank FQI cable plug and the cable shield and, 
depending on findings, for the installation of a by-pass wire. In 
addition, SBF28-28-053 provides a Critical

[[Page 37486]]

Design Configuration Control Limitation (CDCCL) item to make certain 
that the by-pass wire remains installed on these aeroplanes.
    On later production aeroplanes, an improved plug Part Number (P/
N) 20P227-2 was introduced with a better shield connection to the 
housing of the plug. Therefore, SBF28-28-053 (original issue and 
Revision 1) also provided a CDCCL item to ensure that this type of 
plug remains installed on those aeroplanes.
    EASA issued AD 2010-0217 [which corresponds to FAA AD 2011-17-
10, Amendment 39-16774 (76 FR 50111, August 12, 2011)] to require 
accomplishment of the instructions related to the by-pass wire and 
implementation of the CDCCL items as specified in Fokker Services 
SBF28-28-053 Revision 1, as applicable to aeroplane s/n.
    Since EASA AD 2010-0217 was issued, it was identified that P/N 
20P227-1 and 20P228-1 plugs are also approved and can therefore be 
installed on the later production aeroplanes. Prompted by this 
finding, Fokker Services issued SBF28-28-055 to address the 
implementation of a CDCCL item to make certain that only approved 
plug types remain installed on the later production aeroplanes, 
while SBF28-28-053 Revision 2 was issued for early production 
aeroplanes to address the by-pass wire related actions only.
    Consequently, EASA issued AD 2011-0184, retaining the 
requirements of EASA AD 2010-0217, which was superseded, to require 
implementation of the related CDCCL items as specified in Fokker 
Services SBF28-28-053 Revision 2, or SBF28-28-055, as applicable to 
aeroplane s/n.
    More recently, Fokker Services published Revision 3 of SBF28-28-
053, to eliminate the use of a heat gun in or near to the fuel tank, 
and prompted by a change to the definition of the related CDCCL 
item. Fokker Services also cancelled SBF28-28-055, due to the 
introduction of a revised definition of the CDCCL item that has been 
published in Fokker Services SBF28-28-050, Revision 2.
    For the reason described above, this [EASA] AD retains the 
requirements related to SBF28-28-053 of EASA AD 2011-0184, which is 
superseded, but requires those actions to be accomplished in 
accordance with the instructions of Fokker Services SBF28-28-053, 
Revision 3 (R3).
    All the actions related to SBF28-28-055, as previously required 
through paragraphs (5) and (6) of EASA AD 2011-0184, are now 
addressed by EASA AD 2014-0110 [http://ad.easa.europa.eu/ad/2014-0110_1.pdf].
* * * * *
    The CDCCL requirement in AD 2011-17-10 for Model F.28 Mark 2000, 
3000, and 4000 airplanes is now addressed in other related rulemaking. 
Therefore, this AD does not include Model F.28 Mark 2000, 3000, and 
4000 airplanes in the applicability.
    This AD also removes airplanes having serial numbers 11993 and 
11994 from the applicability because those airplanes were scrapped and 
removed from the type certificate data sheet.
    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 Internet at 
http://www.regulations.gov by searching for and locating it in Docket 
No. FAA-2015-8138.

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.

Conclusion

    We reviewed the available 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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Fokker Service Bulletin SBF28-28-
053, Revision 3, dated January 9, 2014. The service information 
describes procedures for inspecting for a by-pass wire between the 
housing of each in-tank FQI cable plug and the cable shield, and 
installing a by-pass wire if necessary. The service information also 
describes CDCCL Item 1.7 for fuel quantity indicating system (FQIS) 
wiring in wing tanks. 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.

Costs of Compliance

    We estimate that this AD affects 5 airplanes of U.S. registry. This 
AD adds a requirement to revise the airplane maintenance or inspection 
program by incorporating the instructions in revised service 
information. The current costs associated with this AD are repeated as 
follows for the convenience of affected operators:
    The actions required by AD 2011-17-10 will take about 6 work-hours 
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 that were required by AD 2011-17-10 is $510 per 
product.
    In addition, we estimate that any necessary follow-on actions 
required by AD 2011-17-10 take about 7 work-hours and require parts 
costing $308, for a cost of $903 per product. We have no way of 
determining the number of products that may need these actions.
    We also estimate that it takes about 1 work-hour per product to 
revise the maintenance or inspection program. 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 $425, 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 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.
