Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to certain Bombardier, Inc. 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 and new repetitive functional tests of the pilot input 
lever of the PFS unit, and corrective actions if necessary; and, after 
initiating the new tests, removing of the existing procedures for the 
repetitive functional tests from the MRM. The existing AD was prompted 
by a report that the shear pin located in the input lever of two PFS 
units failed due to fatigue. Since we issued that AD, a new re-designed 
PFS unit has been developed, which eliminates the need for repetitive 
inspections. This proposed AD would require replacing certain PFS units 
with the new redesigned PFS unit. This proposed AD would also remove 
certain airplanes from the applicability and add certain airplanes to 
the applicability. We are proposing this AD to prevent undetected 
failure of the shear pins of both PFS units simultaneously, which could 
result in loss of pitch feel forces and consequent reduced control of 
the airplane.

Discussion

    On March 31, 2008, we issued AD 2008-08-09, Amendment 39-15461 (73 
FR 19979, April 14, 2008). That AD required actions intended to address 
an unsafe condition on the products listed above.
    Since we issued AD 2008-08-09, Amendment 39-15461 (73 FR 19979, 
April 14, 2008), Transport Canada Civil Aviation (TCCA), which is the 
aviation authority for Canada, has issued Canadian Airworthiness 
Directive CF-2005-41R1, dated May 10, 2012 (referred to after this as 
the Mandatory Continuing Airworthiness Information, or ``the MCAI''), 
to correct an unsafe condition for the specified products. The MCAI 
states:

The shear pin in the input lever of several Pitch Feel Simulators 
(PFS) units has failed due to fatigue. The shear pin failure is not 
always detectable by the flight crew in normal operation. Failure of 
the shear pins in both PFS units on an aeroplane could result in 
loss of pitch feel forces and reduced controllability of the 
aeroplane.
Recently, Transport Canada has certified the new design of the PFS 
unit--part number (P/N) 601R92300-7 as a terminating action.

[[Page 21075]]

Revision 1 of this [TCCA] AD mandates the retrofit of all in-service 
CL-600-2B19 aeroplanes with the redesigned PFS unit.

Required actions include replacing the PFS units having part number (P/
N) 601R92300-3 or 601R92300-5 with PFS units having P/N 601R92300-7, 
which would terminate the actions required by AD 2008-08-09, Amendment 
39-15461 (73 FR 19979, April 14, 2008). This proposed AD also adds 
airplanes having serial numbers (S/Ns) 7991 through 7999 inclusive, and 
removes airplanes having S/Ns 8112 and subsequent. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Bombardier, Inc. has issued Alert Service Bulletin A601R-27-144, 
Revision E, dated October 2, 2012, including Appendix A, Revision A, 
dated December 20, 2006; and Service Bulletin 601R-27-139, Revision A, 
dated May 28, 2012. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

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

    Based on the service information, we estimate that this proposed AD 
would affect about 574 products of U.S. registry.
    The actions that are required by AD 2008-08-09, Amendment 39-15461 
(73 FR 19979, April 14, 2008), and retained in this proposed AD take 
about 2 work-hours per product, at an average labor rate of $85 per 
work hour. Required parts cost about $0 per product. Based on these 
figures, the estimated cost of the currently required actions is $170 
per product.
    We estimate that it would take about 8 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $2,500 
per product. Where the service information lists required parts costs 
that are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the proposed AD 
on U.S. operators to be $1,825,320, or $3,180 per product.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
