Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-17-51 for 
certain Bombardier, Inc. Model CL-600-2B16 airplanes. AD 2014-17-51 
required inspecting the inboard flap fasteners of the hinge-box forward 
fitting at Wing Station (WS) 76.50 and WS 127.25 to determine the 
orientation and condition of the fasteners, as applicable, and 
replacement or repetitive inspections of the fasteners if necessary. AD 
2014-17-51 also provided for optional terminating action for the 
requirements of that AD. This new AD requires accomplishment of the 
previously optional terminating action. This AD was prompted by a 
determination that that additional action is necessary. We are issuing 
this AD to detect and correct incorrectly oriented or fractured 
fasteners, that could result in premature failure of the fasteners 
attaching the inboard flap hinge-box forward fitting; failure of the 
fasteners could lead to the detachment of the flap hinge box and the 
flap surface, and consequent loss of control of the airplane.

DATES: This AD is effective June 6, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 6, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2014-17-51, Amendment 39-17999 (79 FR 64088, 
October 28, 2014) (``AD 2014-17-51''). AD 2014-17-51 applied to certain 
Bombardier, Inc. Model CL-600-2B16 airplanes. The NPRM published in the 
Federal Register on October 19, 2015 (80 FR 63141) (``the NPRM'').
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-27R1, dated August 29, 2014 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc. Model CL-600-
2B16 airplanes. The MCAI states:

    There have been three in-service reports on 604 Variant 
aeroplanes of a fractured fastener head on the inboard flap hinge-
box forward fitting at Wing Station (WS) 76.50, found during a 
routine maintenance inspection. Investigation revealed that the 
installation of these fasteners on the inboard flap hinge-box 
forward fittings at WS 76.50 and WS 127.25, on both wings, does not 
conform to the engineering drawings. Incorrect installation may 
result in premature failure of the fasteners attaching the inboard 
flap hinge-box forward fitting. Failure of the fasteners could lead 
to the detachment of the flap hinge box and consequently the 
detachment of the flap surface. The loss of a flap surface could 
adversely affect the continued safe operation of the aeroplane.
    The original issue of [Canadian] AD CF-2013-39 [http://www.regulations.gov/#!documentDetail;D=FAA-2014-0054-0002] [which 
corresponds to FAA AD 2014-03-17, Amendment 39-17754 (79 FR 9389, 
February 19, 2014)] mandated a detailed visual inspection (DVI) of 
each inboard flap hinge-box forward fitting, on both wings, and 
rectification as required. Incorrectly oriented fasteners require 
repetitive inspections until the terminating action is accomplished.
    After the issuance of [Canadian] AD CF-2013-39, there has been 
one reported incident on a 604 Variant aeroplane where four 
fasteners were found fractured on the same flap hinge-box forward 
fitting. The investigation determined that the fasteners were 
incorrectly installed.
    The original issue of this [Canadian] AD was issued to reduce 
the initial and repetitive inspection intervals previously mandated 
in [Canadian] AD CF-2013-39, and to impose replacement of the 
incorrectly oriented fasteners within 24 months. The CL-600-1A11, -
2A12 and -2B16 (601-3A/-3R Variant) aeroplanes are addressed through 
[Canadian] AD CF-2013-39R1.
    Revision 1 of this [Canadian] AD is issued to clarify the 
requirements for the initial and repetitive inspections.

    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-
3988.

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.

Change to Paragraph (k) of This AD

    Paragraph (k) of the NPRM specified to do the replacement on 
``both'' wings. However, the replacement only needs to be done on the 
affected wing on which incorrectly oriented fasteners were found but 
none were found to be fractured. We have revised paragraph (k) of this 
AD to specify accomplishing the replacement on the affected wings. We

[[Page 26122]]

have coordinated this change with TCCA.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD with the change described 
previously and minor editorial changes. We have determined that these 
minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Alert Service Bulletins:
    <bullet> A604-57-006, Revision 04, dated November 12, 2014, 
including Appendices 1 and 2, dated September 26, 2013; and
    <bullet> A605-57-004, Revision 04, dated November 12, 2014, 
including Appendices 1 and 2, dated September 26, 2013.
    The service information describes repetitive detailed visual 
inspections of each inboard flap fastener of the hinge-box forward 
fitting at WS 76.50 and WS 127.25, on both wings, and, if necessary, 
replacement of the fasteners. 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 285 airplanes of U.S. registry.
    The actions required by AD 2014-17-51, and retained in this AD take 
about 1 work-hour 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 are required by AD 
2014-17-51 is $85 per product.
    We also estimate that it will take about 58 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts cost about $753 per product. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $1,619,655, or $5,683 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 58 work-hours and require parts costing $753, for a cost of 
$5,683 per product. We have no way of determining the number of 
aircraft that might need this action.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.
