Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2014-17-
51, for certain Bombardier, Inc. Model CL-600-2B16 airplanes. AD 2014-
17-51 currently requires 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 provides for optional terminating 
action for the requirements of that AD. Since we issued AD 2014-17-51, 
we have determined that additional action is necessary. This proposed 
AD would also require accomplishment of the previously optional 
terminating action. We are proposing this AD to detect and correct 
incorrectly oriented or fractured fasteners, which 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: We must receive comments on this proposed AD by December 3, 
2015.

Discussion

    On October 13, 2014, we issued AD 2014-17-51, Amendment 39-17999 
(79 FR 64088, October 28, 2014). AD 2014-17-51 requires actions 
intended to address an unsafe condition on certain Bombardier, Inc. 
Model CL-600-2B16 airplanes.
    The preamble to AD 2014-17-51, Amendment 39-17999 (79 FR 64088, 
October 28, 2014), explains that we consider the requirements ``interim 
action'' and were considering further rulemaking. We now have 
determined that further rulemaking is indeed necessary, and this 
proposed AD follows from that determination.
    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.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Alert Service Bulletins:
     A604-57-006, Revision 04, dated November 12, 2014, 
including Appendices 1 and 2, dated September 26, 2013,
     A605-57-004, Revision 04, dated November 12, 2014, 
including Appendices 1 and 2, dated September 26, 2013, and
    The service information describes detailed visual inspection 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 of this 
NPRM.

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 285 airplanes of U.S. 
registry.
    The actions required by AD 2014-17-51, Amendment 39-17999 (79 FR 
64088, October 28, 2014), and retained in this proposed 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 would take about 58 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $753 
per product. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $1,619,655, or $5,683 per product.

[[Page 63143]]

    In addition, we estimate that any necessary follow-on actions would 
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 proposed 
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 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.
