We propose to supersede Airworthiness Directive (AD) 2013-02- 08, for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2013-02-08 currently requires inspecting the trunnions and upper and lower pins of the horizontal stabilizer trim actuator (HSTA), and replacement or re-identification if necessary; and revising the maintenance program to include safe life limits and inspection requirements for the HSTA. Since we issued AD 2013-02-08, we determined that not all affected attachment pins and trunnions were included in the required inspections. In addition, for certain airplanes on which the replacement in AD 2013-02-08 was done, incorrect attachment hardware may have been used. This proposed AD would require measuring the diameter of certain bolts and attach holes, and, as applicable, measuring the diameter of the attach holes in the trunnions and pins, doing detailed visual inspections of the trunnions, pins, and spacers, doing corrective actions, and re-identifying trunnions and pins. This proposed AD also requires revising the maintenance or inspection program. This proposed AD also removes certain airplanes from the applicability. We are proposing this AD to prevent failure of the attachment pins and trunnions of the HSTA. This condition could result in separation of the horizontal stabilizer, and consequent loss of control of the airplane.

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) 2013-02-
08, for all Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 
& 440) airplanes. AD 2013-02-08 currently requires inspecting the 
trunnions and upper and lower pins of the horizontal stabilizer trim 
actuator (HSTA), and replacement or re-identification if necessary; and 
revising the maintenance program to include safe life limits and 
inspection requirements for the HSTA. Since we issued AD 2013-02-08, we 
determined that not all affected attachment pins and trunnions were 
included in the required inspections. In addition, for certain 
airplanes on which the replacement in AD 2013-02-08 was done, incorrect 
attachment hardware may have been used. This proposed AD would require 
measuring the diameter of certain bolts and attach holes, and, as 
applicable, measuring the diameter of the attach holes in the trunnions 
and pins, doing detailed visual inspections of the trunnions, pins, and 
spacers, doing corrective actions, and re-identifying trunnions and 
pins. This proposed AD also requires revising the maintenance or 
inspection program. This proposed AD also removes certain airplanes 
from the applicability. We are proposing this AD to prevent failure of 
the attachment pins and trunnions of the HSTA. This condition could 
result in separation of the horizontal stabilizer, and consequent loss 
of control of the airplane.

DATES: We must receive comments on this proposed AD by August 29, 2016.

Discussion

    On, January 16, 2013, we issued AD 2013-02-08, Amendment 39-17329 
(78 FR 7647, February 4, 2013) (``AD 2013-02-08''). AD 2013-02-08 
requires actions intended to address an unsafe condition on all 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes.
    Since we issued AD 2013-02-08, we have determined that not all 
affected attachment pins and trunnions were included in the required 
inspections of AD 2013-02-08. In addition, for airplanes on which 
certain service information was incorporated, incorrect attachment 
hardware may have been used to re-install the HSTA attachment pins and 
trunnions.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-08, dated March 30, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes. The MCAI states:


[[Page 45993]]


    After the issuance of [Canadian] AD CF-2011-45, it was 
discovered that the [Canadian] AD did not address all affected 
Horizontal Stabilizer Tim Actuator (HSTA) attachment pins and 
trunnions. In addition, it is possible that aeroplanes having 
incorporated the Initial issue or Revision A, of Bombardier Service 
Bulletin (SB) 601R-27-160 used incorrect attachment hardware to re-
install the HSTA attachment pins or trunnions.
    This [Canadian] AD mandates the inspection and rectification, as 
required, and the re-identification, as required, of the HSTA pins 
and trunnions and incorporation of a revised Airworthiness 
Limitation task.

    The required actions include measuring the diameter of the bolts 
that attach the trunnions and pins, measuring the diameter of the 
attach holes in the aircraft structure, and, as applicable, measuring 
the diameter of the attach holes in the trunnions and pins, doing 
detailed visual inspections for gouges, scratches, and corrosion of the 
trunnions and pins, doing detailed visual inspections for damage of the 
spacers, doing corrective actions, and re-identifying trunnions and 
pins. Corrective actions include replacing bolts, trunnions, pins, and 
spacers, increasing the diameter of the attach holes, and repairing 
trunnions and pins.
    This proposed AD also removes certain airplanes from the 
applicability to correspond with the MCAI, which removed them from its 
applicability.
    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-2016-
7427.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 601R-27-160, Revision D, 
dated October 22, 2015. The service information describes procedures 
for measuring the diameter of certain bolts and attach holes, and, as 
applicable, measuring the diameter of the attach holes in the trunnions 
and pins, doing detailed visual inspections of the trunnions, pins, and 
spacers, doing corrective actions, and re-identifying trunnions and 
pins.
    Bombardier has also issued Bombardier Temporary Revision 2B-2245, 
dated October 17, 2014, to Appendix B--Airworthiness Limitations, of 
Part 2, Airworthiness Requirements, of the Bombardier CL-600-2B19 
Maintenance Requirements Manual to incorporate a revised Airworthiness 
Limitation task. The service information describes safe life limits for 
the HSTA trunnion support and attaching hardware.
    Bombardier has also issued Bombardier Temporary Revision 2B-2186, 
dated August 8, 2011, to Appendix B--Airworthiness Limitations, Part 2, 
Airworthiness Requirements, of the Bombardier CL-600-2B19 Maintenance 
Requirements Manual to incorporate a revised Airworthiness Limitation 
task. The service information describes an inspection of the upper and 
lower installation pins of the horizontal stabilizer pitch trim 
actuator.
    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 design.

Costs of Compliance

    We estimate that this proposed AD affects 489 airplanes of U.S. 
registry.
    We estimate that it would take about 8 work-hours per product to 
comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $332,520, or $680 
per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 20 work-hours and require parts costing $4,391, for a cost 
of $6,091 per product. We have no way of determining the number of 
products that may need these actions.

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.
