14 CFR Part 39
[Docket No. FAA-2006-24252; Directorate Identifier 2006-NM-062-AD;
Amendment 39-14528; AD 2006-05-11 R1]
RIN 2120-AA64
Airworthiness Directives; Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is revising an existing airworthiness directive (AD),
which applies to certain Bombardier Model CL-600-2B19 (Regional Jet
Series 100 & 440) airplanes. The existing AD currently requires
revising the airworthiness limitations section of the Instructions for
Continued Airworthiness of the maintenance requirements manual (MRM) by
incorporating procedures for repetitive functional tests of the pilot
input lever of the pitch feel simulator (PFS) units. That AD also
requires new repetitive functional tests of the pilot input lever of
the PFS unit, and corrective actions if necessary; and after initiating
the new tests, requires removal of the existing procedures for the
repetitive functional tests from the MRM. This AD retains the
requirements of the existing AD and further clarifies the requirements
of the AD. This AD results from a report that the shear pin located in
the input lever of two PFS units failed due to fatigue. We are issuing
this AD to prevent undetected failure of the shear pin of both PFS
units simultaneously, which could result in loss of pitch feel forces
and consequent reduced control of the airplane.
DATES: The effective date of this AD is March 27, 2006.
On March 27, 2006 (71 FR 12277, March 10, 2006), the Director of
the Federal Register approved the incorporation by reference of a
certain publication.
On February 13, 2004 (69 FR 4234, January 29, 2004), the Director
of the Federal Register approved the incorporation by reference of
Bombardier Temporary Revision 2B-1784, dated October 24, 2003, to the
CL-600-2B19 Canadair Regional Jet Maintenance Requirements Manual, Part
2, Appendix B, ``Airworthiness Limitations.''
We must receive any comments on this AD by May 30, 2006.

SUPPLEMENTARY INFORMATION:
Discussion
On February 28, 2006, we issued AD 2006-05-11, amendment 39-14508
(71 FR 12277, March 10, 2006). That AD applies to certain Bombardier
Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. That AD
requires revising the airworthiness limitations section of the
Instructions for Continued Airworthiness of the maintenance
requirements manual (MRM) by incorporating procedures for repetitive
functional tests of the pilot input lever of the pitch feel simulator
(PFS) units. That AD also requires new repetitive functional tests of
the pilot input lever of the PFS unit, and corrective actions if
necessary; and after initiating the new tests, requires removal of the
existing procedures for the repetitive functional tests from the MRM.
That AD resulted from a report that the shear pin located in the input
lever of two PFS units failed due to fatigue. The actions specified in
that AD are intended to prevent undetected failure of the shear pin of
both PFS units simultaneously, which could result in loss of pitch feel
forces and consequent reduced control of the airplane.
Actions Since AD Was Issued
Since we issued that AD, we received telephone calls from three
airplane operators. Two operators stated that the requirement to remove
the functional check specified in paragraph (f) of the AD from the CL-
600-2B19 Canadair Regional Jet Maintenance Requirements Manual was
confusing and will cause an undue burden of possibly grounding
airplanes. The third commenter stated that the reference to ``aircraft
maintenance manual'' in paragraph (f) of the AD should be changed to
``aircraft maintenance requirements manual'' for clarification
purposes. That operator stated that it has both types of manuals and
was not sure which manual needed to be revised.
We agree with the operators that clarification is necessary. It was
our intent that paragraph (f) of that AD refer to the ``maintenance
requirements manual''; we have revised paragraph (f) of this AD
accordingly. It was our intent that after accomplishing the initial
functional test required by paragraph (g) of that AD, operators could
stop performing the requirements of paragraph (f) of that AD and the
repetitive functional checks of the pilot input lever of the PFS units,
Task R27-31-A024-01, specified in the Airworthiness Limitations (AWL)
section of the Instructions for Continued Airworthiness. Therefore, we
have revised paragraph (g) of this AD to clarify this point.
[[Page 15324]]
FAA's Determination and Requirements of This AD
This airplane model is manufactured in Canada and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement.
Therefore, we are issuing this AD to revise AD 2006-05-11. This new
AD retains the requirements of the existing AD and further clarifies
the requirements of the AD.
Interim Action
This is considered to be interim action. The inspection reports
that are required by this AD will enable the manufacturer to obtain
better insight into the nature, cause, and extent of the failures of
the shear pins of the PFS units, and eventually to develop final action
to address the unsafe condition. Once final action has been identified,
the FAA may consider further rulemaking.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed in the ADDRESSES section. Include ``Docket No. FAA-2006-
24252; Directorate Identifier 2006-NM-062-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD that might
suggest a need to modify it.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you may visit
http://dms.dot.gov.
Examining the Dockets
You may examine the AD docket on the Internet at http://dms.dot.gov
, or in person at the Docket Management Facility office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section. Comments will be
available in the AD docket shortly after the Docket Management System
receives them.
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 have 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 the 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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD. See the ADDRESSES section for a location to
examine the regulatory evaluation.
