Airworthiness Directives; Fokker Services B.V.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD), for 
certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This 
proposed AD was prompted by an analysis which determined that, for 
certain areas of the fuselage, the current threshold of an 
Airworthiness Limitations Section inspection is insufficient to detect 
early crack development. This proposed AD would require one time high 
and low frequency eddy current inspections of the affected fuselage 
skin for cracks and repair if necessary. We are proposing this AD to 
detect and correct cracks in the fuselage skin; such cracking could 
result in reduced structural integrity of the fuselage.

DATES: We must receive comments on this proposed AD by October 24, 
2016.

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 Airworthiness Directive 2016-0029, dated 
February 23, 2016 (referred

[[Page 62030]]

to after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Fokker 
Services B.V. Model F28 Mark 0100 airplanes. The MCAI states:

    Recently, a complementary fatigue and damage tolerance analysis 
was accomplished by the design approval holder on the traffic 
collision avoidance system (TCAS) antenna installation on the top of 
the fuselage between station (STA) 6805 and STA7305. Based on the 
results, it was determined that for the affected area, the current 
threshold of the Airworthiness Limitations Section inspection task 
533001-00-20 (special detailed inspection of longitudinal lap 
joints) is insufficient to timely detect possible crack development.
    This condition, if not detected and corrected, could affect the 
structural integrity of the fuselage in this area.
    To address this potential unsafe condition, Fokker Services 
published Service Bulletin (SB) SBF100-53-130 to provide inspection 
instructions. For the reasons described above, this [EASA] AD 
requires a one-time inspection [high and low frequency eddy current 
inspections for cracks] of the fuselage skin around the largest TCAS 
antenna external doubler and of the longitudinal lap joint at 
stringer (STR) 37 between fuselage STA6805 and STA7305 [and repair 
if necessary. This [EASA] AD is considered to be an interim action 
and further [EASA] AD action may follow.
    More information on this subject can be found in Fokker Services 
All Operators Message AOF100.199.

    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-
9058.

Related Service Information Under 1 CFR Part 51

    We reviewed Fokker Service Bulletin SBF100-53-130, dated December 
01, 2015. This service information describes one-time high and low 
frequency eddy current inspections for cracks of the fuselage skin. 
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.

Costs of Compliance

    We estimate that this proposed AD affects 8 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
               Action                        Labor cost           Parts cost        product         operators

Inspection..........................  1 work-hour x $85 per                $0              $85             $680
                                       hour = $85.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this proposed 
AD.

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.
