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) 2015-02-
23, 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. AD 2015-02-23 currently 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. The preamble to AD 2015-02-23 explains that we consider the 
requirements interim action and are considering further rulemaking. We 
now have determined that further rulemaking is indeed necessary, and 
that replacement of the fasteners is necessary. This proposed AD would 
require terminating action to replace the fasteners on the inboard flap 
hinge-box forward fittings on both wings. We are proposing 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: We must receive comments on this proposed AD by June 6, 2016.

Discussion

    On January 20, 2015, we issued AD 2015-02-23, Amendment 39-18092 
(80 FR 5670, February 3, 2015) (``AD 2015-02-23''). AD 2015-02-23 
requires actions intended to address 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. AD 2015-02-
23 corresponds to Canadian Emergency Airworthiness Directive CF-2013-
39R2, dated December 12, 2014 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''). The MCAI was 
issued by Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada.
    The preamble to AD 2015-02-23 explains that we consider the 
requirements interim action and are considering further rulemaking. We 
have now determined that further rulemaking is indeed necessary and 
that, instead of continuing repetitive inspections, replacement of the 
incorrectly oriented fasteners is necessary. This proposed AD follows 
from that determination. This proposed AD would require terminating 
action to replace the fasteners on the inboard flap hinge-box forward 
fittings on affected wings.
    The repetitive inspections can only detect if a fastener head has 
fractured and sheared off. For incorrectly oriented fasteners, it is 
not possible to detect whether a crack has already initiated and 
propagated. The fastener fracture speed is unpredictable due to the 
variability in the quality of the hole preparation prior to fastener 
installation and whether there was any misalignment in the installation 
of the fasteners. The failure of two fasteners could result in the loss 
of the flap attachment, causing flap asymmetry and consequent reduced 
controllability of the airplane.
    We are proposing 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.

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 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.

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 designs.

Clarification of Intent of the MCAI

    Paragraph C. of Canadian Emergency AD CF-2013-39R2, dated December 
12, 2014, specifies to do the replacement on ``both'' wings. We have 
clarified with TCCA that the intent of paragraph C. of Canadian 
Emergency AD CF-2013-39R2, dated December 12, 2014, is that for 
airplanes on which any incorrectly oriented fastener, and no fractured 
or missing fastener, was detected, 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.
    The replacement of all forward and aft fasteners, regardless of 
condition or orientation, at wing station (WS) 76.50 and WS 127.25, on 
the affected wings, constitutes terminating action. Fasteners that have 
cracks or fractures were already addressed by the requirements of AD 
2015-02-13, which is restated in this proposed AD.

Costs of Compliance

    We estimate that this proposed AD affects 120 airplanes of U.S. 
registry.
    The actions required by AD 2015-02-23, and retained in this 
proposed AD, take about 1 work-hour per product, at an average labor 
rate of $85 per work-hour. Based on these figures, the estimated cost 
of the actions that are required by AD 2015-02-23 is $85 per product.
    We also estimate that it would take about 59 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. We have received no definitive data 
that would enable us to provide cost estimates for the parts cost. 
Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $601,800, or $5,015 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 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 available 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.

[[Page 23204]]

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.
