RIN 2120-AA64


Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Fokker Services B.V. Model F.28 Mark 0070 and Mark 0100 airplanes. This 
proposed AD was prompted by reports of cracking in a certain area of 
the pressure bulkhead webplate and skin connection angle. This proposed 
AD would require a one-time inspection of the affected pressure 
bulkhead webplate and skin connection angle, and corrective actions if 
necessary. We are proposing this AD to detect and correct cracking of 
the pressure bulkhead webplate and skin connection angle that could 
lead to sudden inflight decompression of the airplane resulting in 
injury to occupants.

DATES: We must receive comments on this proposed AD by May 13, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.
     Fax: 202-493-2251.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2015-0024, dated February 19, 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.28 Mark 0070 and Mark 0100 series airplanes. The MCAI 
states:

    Service experience with the Fokker 100 type design has shown 
that cracking can occur in the pressure bulkhead webplate and skin 
connection angle on the right hand (RH) side at station 14911 
(station 12447 for F28 Mark 0070) at stringer 67 of fuselage section 
2, before reaching the existing threshold for inspection per ALS 
[Airworthiness Limitations Section] task 533016-00-03 (F28 Mark 
0100) or task 533016-01-03 (F28 Mark 0070). Any cracks in this area 
are not visible from the outside (covered by fairing) until they 
reach a critical length.
    This condition, if not detected and corrected, could lead to 
sudden in-flight decompression of the aeroplane, possibly resulting 
in injury to occupants.
    To address this potential unsafe condition, Fokker Services 
published Service Bulletin (SB) SBF100-53-128, which provides 
inspection instructions to detect any crack in the affected area.
    For the reasons described above, this [EASA] AD requires a one-
time inspection of the affected pressure bulkhead webplate and skin 
connection angle, and, depending on findings, accomplishment of 
applicable corrective action(s).
    This AD is considered to be an interim action and further AD 
action may follow, possibly to lower the current ALS task threshold, 
if justified by the inspection results.

    Corrective actions include repair of cracking in the skin 
connection angle and pressure bulkhead webplate, as applicable.
    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-2016-
5035.

Related Service Information Under 1 CFR Part 51

    Fokker Services B.V. has issued Fokker Service Bulletin SBF100-53-
128, dated November 12, 2014; and Fokker Service Bulletin SBF100-53-
129, dated February 16, 2015. The service information describes 
procedures for inspection of the affected pressure bulkhead webplate 
and skin connection angle, and corrective actions if necessary. 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.

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.

Differences Between This Proposed AD and the MCAI and Service 
Information

    Although the MCAI and service information allow further flight 
after cracks are found during compliance with the proposed actions, 
paragraph (g)(2) of this proposed AD requires that you repair the crack 
before further flight.

Costs of Compliance

    We estimate that this proposed AD affects 8 airplanes of U.S. 
registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this proposed AD, and 1 work-
hour per product for reporting. 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 $170 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 46 work-hours and require parts costing $2,000, for a cost 
of $5,910 per product. We have no way of determining the number of 
aircraft that might need these actions.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid

[[Page 17419]]

OMB control number. The control number for the collection of 
information required by this proposed AD is 2120-0056. The paperwork 
cost associated with this proposed AD has been detailed in the Costs of 
Compliance section of this document and includes time for reviewing 
instructions, as well as completing and reviewing the collection of 
information. Therefore, all reporting associated with this proposed AD 
is mandatory. Comments concerning the accuracy of this burden and 
suggestions for reducing the burden should be directed to the FAA at 
800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

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.

paragraph (g) within 2,000 flight cycles after the effective date of 
this AD.
    (2) For airplanes that have accumulated 40,000 or more total 
flight cycles as of the effective date of this AD, do the actions in

227-1149. Information may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. 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) Contacting the Manufacturer: For any requirement in this AD
