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.
