Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and 
CL-600-2B16 (CL-601-3A, and CL-601-3R Variants) airplanes. This AD 
requires repetitive inspections for fractured or incorrectly oriented 
fasteners on the inboard flap hinge-box forward fittings on both wings, 
and replacement of all fasteners, if necessary. This AD was prompted by 
several reports of incorrectly oriented and fractured fasteners found 
on the inboard flap hinge-box forward fitting at wing station (WS) 
76.50. We are issuing this AD to detect and correct incorrectly 
oriented or fractured fasteners, which could result in detachment of 
the flap hinge-box and the flap surface, and consequent reduced 
controllability of the airplane.

DATES: This AD becomes effective February 18, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of February 18, 
2015.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Emergency Airworthiness 
Directive CF-2013-39R2, dated December 12, 2014 (referred to after this 
as the Mandatory Continuing Airworthiness Information, or ``the 
MCAI''), to correct an unsafe condition on certain Bombardier, Inc. 
Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-
601-3A, and CL-601-3R Variants) 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 * * 
* [result in reduced controllability of the airplane].
    The original issue of this [Canadian] AD [dated December 6, 
2013] [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.
    Although there have been no reported fractured fastener heads 
found to date on any model CL-600-1A11, -2A12 or -2B16 (601-3A-3R 
Variant) aeroplanes, incorrectly oriented fasteners may also be 
installed.
    After the issuance of the original [Canadian] AD [dated August 
15, 2014], 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.
    Revision 1 of this [Canadian] AD was issued to remove the 604 
Variant aeroplanes from the Applicability section since they were 
addressed in [Canadian] AD CF-2014-27 [dated August 15, 2014] [which 
corresponds to FAA AD 2014-17-51, Amendment 39-17999 (79 FR 64088, 
October 28, 2014)] and to clarify paragraphs A.2. and C of this 
[Canadian] AD so that it matched the Bombardier Alert Service 
Bulletins.
    After the issuance of Revision 1 of this [Canadian] AD, there 
have been several reports of incorrectly oriented fasteners found on 
CL-600-1A11, and -2B16 (601-3A Variant) aeroplanes. Although there 
have been no reports of fractured fasteners found to date, 
incorrectly oriented fasteners could result in the premature failure 
of the forward flap hinge-box fitting.
    Revision 2 of this [Canadian] AD is issued to reduce the initial 
and repetitive inspection intervals and to impose replacement of the 
incorrectly oriented fasteners * * *. This [Canadian] AD also 
corrects various terminology errors which were found in previous 
French versions of this [Canadian] AD.

Related Rulemaking

    On February 3, 2014, we issued AD 2014-03-17, Amendment 39-17754 
(79 FR 9389, February 19, 2014) for Bombardier, Inc. Model CL-600-1A11 
(CL-600) airplanes, having serial numbers (S/Ns) 1004 through 1085 
inclusive; Model CL-600-2A12 (CL-601) airplanes, having S/Ns 3001 
through 3066 inclusive; and Model CL-600-2B16 (CL-601-3A, CL-601-3R, & 
CL-604 Variants) airplanes, having S/Ns 5001 through 5194 inclusive, 
5301 through 5665 inclusive, and 5701 through 5920 inclusive. AD 2014-
03-17 requires repetitive inspections for fractured or incorrectly 
oriented fasteners on the inboard flap hinge-box forward fittings on 
both wings, and fastener replacement if necessary, and was prompted by 
two reports of fractured fastener heads found on the inboard flap 
hinge-box forward fitting. AD 2014-03-17 was issued to detect and 
correct incorrectly oriented or fractured fasteners, which could result 
in detachment of the flap hinge-box and the flap surface, and 
consequent reduced controllability of the airplane.
    After we issued AD 2014-03-17, Amendment 39-17754 (79 FR 9389, 
February 19, 2014), we received a report of an additional incident of 
fractured fasteners on a Model CL-600-2B16 (CL-604 Variant) airplane. 
We then issued AD 2014-17-51, Amendment 39-17999 (79 FR 64088, October 
28, 2014), as a ``stand-alone'' AD to reduce compliance times for the 
initial and repetitive inspections only for Model CL-600-2B16 airplanes 
having S/Ns 5301 through 5665 inclusive, and 5701 through 5920 
inclusive. Issuing AD 2014-17-51 as a ``stand-alone'' AD instead of 
superseding AD 2014-03-17 was determined to be clearer and less 
burdensome for operators with airplanes unaffected by the reduced 
compliance times required by AD 2014-17-51.
    Since we issued AD 2014-17-51, Amendment 39-17999 (79 FR 64088, 
October 28, 2014), we received a report of incorrectly oriented 
fasteners on a Model CL-600-1A11 airplane and on a Model CL-600-2B16 
(601-3A Variant) airplane. Consequently, we determined it was necessary 
to issue this AD to reduce compliance times for the other airplane 
models not affected by AD 2014-17-51. Doing so reduces the potential 
complexity for two groups of airplanes (those that are and are not 
affected by AD 2014-17-51).

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Alert Service Bulletins A600-0763, Revision 
02, dated December 9, 2014, including Appendices 1 and 2, dated 
September 26, 2013; and A601-0627, Revision 02, dated December 9, 2014, 
including Appendices 1 and 2, dated September 26, 2013. The service 
information describes procedures for repetitive inspections of the 
fasteners on the inboard flap hinge-box forward fittings on both wings, 
and replacement of all fasteners, if necessary. The actions described 
in this service information are

[[Page 5672]]

intended to correct the unsafe condition identified in the MCAI. This 
service information is reasonably available; see ADDRESSES for ways to 
access this service information.

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 and service 
information referenced above. 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 these 
same type designs.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because we 
have received several reports of incorrectly oriented and fractured 
fasteners found on the inboard flap hinge-box forward fitting at WS 
76.50. Incorrectly oriented or fractured fasteners could result in 
detachment of the flap hinge-box and the flap surface, and consequent 
reduced controllability of the airplane. Therefore, we determined that 
notice and opportunity for public comment before issuing this AD are 
impracticable and that good cause exists for making this amendment 
effective in fewer than 30 days.

Interim Action

    We consider this AD interim action. We are currently considering 
requiring replacement of incorrectly oriented fasteners, which will 
constitute terminating action for the repetitive inspections required 
by this AD action. However, the planned compliance time for the 
replacement would allow enough time to provide notice and opportunity 
for prior public comment on the merits of the modification.

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-2015-0082; Directorate 
Identifier 2014-NM-233-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

    We estimate that this AD affects 120 airplanes of U.S. registry.
    We also estimate that it will take about 1 work-hour per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD on U.S. operators to be $10,200, or $85 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.
