Airworthiness Directives; Fokker Services B.V. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 95-25-02, 
which applied to certain Fokker Services B.V. Model F28 Mark 0100

[[Page 1533]]

airplanes. AD 95-25-02 required inspection(s) to detect cracks of the 
fuselage-mounted half of hinge assemblies of the small cargo door, and 
replacement of any cracked hinge assembly with a new hinge assembly. 
This new AD was prompted by a report that the hinges of the small cargo 
door are made of a material that is sensitive to stress corrosion and 
fatigue cracking, and by the determination that the existing inspection 
program does not provide sufficient protection against fatigue-induced 
cracks. This AD requires contacting the FAA to obtain instructions for 
addressing the unsafe condition on these products, and doing the 
actions specified in those instructions. We are issuing this AD to 
address the unsafe condition on these products.

DATES: This AD becomes effective January 29, 2018.
    We must receive comments on this AD by February 26, 2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued AD 95-25-02, Amendment 39-9446 (60 FR 63615, December 12, 
1995) (``AD 95-25-02''), which applied to certain Fokker Services B.V. 
Model F28 Mark 0100 airplanes. AD 95-25-02 was prompted by a report 
that the hinges of the small cargo door are made of a material that is 
sensitive to stress corrosion cracking. AD 95-25-02 required 
inspection(s) to detect cracks of the fuselage-mounted half of hinge 
assemblies of the small cargo door, and replacement of any cracked 
hinge assembly with a new hinge assembly. We issued AD 95-25-02 to 
prevent failure of the hinges of the small cargo door due to stress 
corrosion cracking, which could result in opening and/or separation of 
the door while the airplane is in flight, and resultant rapid 
decompression and/or structural damage to the airplane.
    Since we issued AD 95-25-02, we have determined that the existing 
inspection program does not provide sufficient protection against 
fatigue-induced cracks.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2013-0028, dated February 8, 2013 (referred 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:

    Over the years, stress corrosion- and fatigue-induced cracks 
were found on the hinges of the downward opening small cargo doors 
installed on Fokker F28 Mark 0100 aeroplanes.
    To address the potential unsafe condition with respect to stress 
corrosion, CAA-NL issued AD (BLA) 93-036/2 [which corresponded to 
FAA AD 95-25-02] to require repetitive inspections and, if cracks 
are found, replacement of the hinges with hinges of a new design. 
These new hinges were installed before delivery on aeroplanes with 
s/n 11409 and higher.
    To ensure the continued structural integrity with respect to 
fatigue, a repetitive inspection was included in the Airworthiness 
Limitations Section (ALS) of the Instructions for Continued 
Airworthiness.
    As part of the Widespread Fatigue Damage re-evaluation, it was 
concluded that the repetitive fatigue inspection in the ALS does not 
provide a sufficient level of protection against the fatigue-induced 
cracks.
    For the reasons described above, this [EASA] AD retains the 
requirements of CAA-NL AD 93-036/2, which is superseded, and 
requires replacement of Part Number (P/N) A28410-405 and P/N A28410-
407 hinges with modified P/N D28410-409 hinges.

    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2017-
1242.

FAA's Determination and Requirements of This 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. We are 
issuing this AD because we evaluated all pertinent information and 
determined the unsafe condition exists and is likely to exist or 
develop on other products of the same type design.

FAA's Determination of the Effective Date

    Since there are currently no domestic operators of this product, we 
find good cause that notice and opportunity for prior public comment 
are unnecessary. In addition, for the reason(s) stated above, we find 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2017-1242; Product 
Identifier 2013-NM-043-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    Currently, there are no affected U.S.-registered airplanes. This AD 
requires contacting the FAA to obtain instructions for addressing the 
unsafe condition, and doing the actions specified in those 
instructions. Based on the actions specified in the MCAI AD,

[[Page 1534]]

we are providing the following cost estimates for an affected airplane 
that is placed on the U.S. Register in the future:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost                Parts cost           Cost per product
----------------------------------------------------------------------------------------------------------------
Inspections (retained actions from   2 work-hours x $85 per hour  $0....................  $170 per inspection
 AD 95-25-02).                        = $170 per inspection                                cycle.
                                      cycle.
Replacement (new action)...........  Up to 186 work-hours x $85   Up to $7,700..........  Up to $23,510.
                                      per hour = $15,810.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
replacements that would be required based on the results of the 
required actions:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
               Action                         Labor cost                Parts cost           Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement (retained actions from   Up to 186 work-hours x $85   Up to $7,700..........  Up to $23,510.
 AD 95-25-02).                        per hour = $15,810.

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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.
