Appendix to Airworthiness Directive 2009– 05–05 Limitations Regarding Avidyne Primary Flight Displays (PFDs) Before conducting flight operations, pilots must review and be familiar with the Crosscheck Monitor section of the Avidyne Primary Flight Display Pilot’s Guide and all limitations contained in the aircraft operating handbook. VerDate Nov<24>2008 14:27 Feb 26, 2009 Jkt 217001 Procedures As a normal practice, all pilots should be vigilant in conducting proper preflight and in-flight checks of instrument accuracy, including: • Preflight check of the accuracy of both the primary and backup altimeter against known airfield elevation and against each other. • Verification of airspeed indications consistent with prevailing conditions at startup, during taxi, and prior to takeoff. • ‘‘Airspeed alive’’ check and reasonable indications during takeoff roll. • Maintenance of current altimeter setting in both primary and backup altimeters. • Cross-check of primary and backup altimeters at each change of altimeter setting and prior to entering instrument meteorological conditions (IMC). • Cross-check of primary and backup altimeters and validation against other available data, such as glideslope intercept altitude, prior to conducting any instrument approach. • Periodic cross-checks of primary and backup airspeed indicators, preferably in combination with altimeter cross-checks. For flight operations under instrument flight rules (IFR) or in conditions in which visual reference to the horizon cannot be reliably maintained (that is IMC, night operations, flight operations over water, in haze or smoke) and the pilot has reasons to suspect that any source (PFD or back-up instruments) of attitude, airspeed, or altitude is not functioning properly, flight under IFR or in these conditions must not be initiated (when condition is determined on the ground) and further flight under IFR or in these conditions is prohibited until equipment is serviced and functioning properly. Operation of aircraft not equipped with operating backup (or standby) attitude, altimeter, and airspeed indicators that are located where they are readily visible to the pilot is prohibited. Pilots must frequently scan and crosscheck flight instruments to make sure the information depicted on the PFD correlates and agrees with the information depicted on the backup instruments.

SUPPLEMENTARY INFORMATION: dwashington3 on PROD1PC60 with RULES Discussion Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, notified us that an unsafe condition may exist on Bombardier Model CL–215–6B11 (CL–215T variant) and CL–215–6B11 (CL–415 variant) airplanes. TCCA advises that during a routine inspection, an operator reported corrosion on the rudder lower torque tube upper bearing, part number DAT48–64A, on two airplanes. These bearings had been installed in accordance with Bombardier Service Bulletin 215–4328, Revision 3, dated May 20, 2008, as part of the torque tube replacement. Corroded lower torque tube upper bearings can lead to hinge deformation, which could result in a rudder jam and consequent reduced controllability of the airplane. Relevant Service Information Bombardier has issued Bombardier Service Bulletin 215–3151, dated May 5, 2008 (for 215T variant airplanes); and Bombardier Service Bulletin 215–4394, dated May 5, 2008 (for 415 variant airplanes). These service bulletins describe procedures for repetitive detailed inspections for signs of contamination, including corrosion/rust particles in the flange and housing of the rudder lower torque tube upper bearing. These service bulletins also describe procedures for bearing wear checks, and grease applications of the rudder lower torque tube upper bearing, and a rudder upper hinge gap check; and related investigative and corrective actions if necessary. Related investigative actions include inspecting old grease for signs of contamination, measuring the distance from the top of the bearing housing to the top of the lower bearing flange shoulder at multiple locations around the bearing, and doing a visual inspection to determine the cause of the excessive wear. Corrective actions include replacing the bearing(s) and adjusting the hinge gap. TCCA mandated the service information and issued Canadian airworthiness directive CF– 2008–29, dated August 20, 2008 (referred to after this as ‘‘the MCAI’’), to ensure the continued airworthiness of these airplanes in Canada. FAA’s Determination and Requirements of This 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 issuing 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. Therefore, we are issuing this AD to detect and correct corroded bearings 8861 which can lead to hinge deformation, and result in a rudder jam and consequent reduced controllability of the airplane. This AD requires accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Differences Between This AD and the Canadian Airworthiness Directive.’’ Differences Between This AD and the Canadian Airworthiness Directive Bombardier Service Bulletin 215– 3151, dated May 5, 2008 (for 215T variant airplanes); and Bombardier Service Bulletin 215–4394, dated May 5, 2008 (for 415 variant airplanes) recommend accomplishing the required actions ‘‘before and after every fire season,’’ but we find this interval to be imprecise and vague. In developing appropriate compliance times for this AD, we considered not only the manufacturer’s recommendation, but the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the required actions. In light of all of these factors, we find that a 6-month repetitive interval for the required actions is an appropriate interval of time for affected airplanes to continue to operate without compromising safety. This difference has been coordinated with TCCA. Interim Action We consider this proposed AD interim action. If final action is later identified, we might consider further rulemaking then. Costs of Compliance None of the airplanes affected by this action are on the U.S. Register. All airplanes affected by this AD are currently operated by non-U.S. operators under foreign registry; therefore, they are not directly affected by this AD action. However, we consider this AD necessary to ensure that the unsafe condition is addressed if any affected airplane is imported and placed on the U.S. Register in the future. The following table provides the estimated costs to comply with this AD for any affected airplane that might be imported and placed on the U.S. Register in the future. ESTIMATED COSTS Action Work hours Average labor rate per hour Parts cost Inspection ................................................................................................. 4 $80 None .........

Therefore, providing notice and opportunity for public comment is unnecessary before this AD is issued, and this AD may be made effective in less than 30 days after it is published in the Federal Register. dwashington3 on PROD1PC60 with RULES Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not provide you with notice and an opportunity to provide your comments before it becomes effective. However, we invite you to send any written data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA– 2009–0159; Directorate Identifier 2008– NM–175–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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 VerDate Nov<24>2008 14:27 Feb 26, 2009 Jkt 217001 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 and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation.

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier Model CL-215-6B11 (CL-215T variant) and CL-215-6B11 
(CL-415 variant) airplanes. This AD requires repetitive inspections for 
contamination of grease, bearing wear checks, grease applications of 
the rudder lower torque tube upper bearing, and a rudder upper hinge 
gap check; and related investigative and corrective actions if 
necessary. This AD results from a report of corrosion on the rudder 
lower torque tube upper bearing. We are issuing this AD to detect and 
correct corroded bearings which could lead to hinge deformation, and 
could result in a rudder jam and consequent reduced controllability of 
the airplane.

SUPPLEMENTARY INFORMATION:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the airworthiness 
authority for Canada, notified us that an unsafe condition may exist on 
Bombardier Model CL-215-6B11 (CL-215T variant) and CL-215-6B11 (CL-415 
variant) airplanes. TCCA advises that during a routine inspection, an 
operator reported corrosion on the rudder lower torque tube upper 
bearing, part number DAT48-64A, on two airplanes. These bearings had 
been installed in accordance with Bombardier Service Bulletin 215-4328, 
Revision 3, dated May 20, 2008, as part of the torque tube replacement. 
Corroded lower torque tube upper bearings can lead to hinge 
deformation, which could result in a rudder jam and consequent reduced 
controllability of the airplane.

Relevant Service Information

    Bombardier has issued Bombardier Service Bulletin 215-3151, dated 
May 5, 2008 (for 215T variant airplanes); and Bombardier Service 
Bulletin 215-4394, dated May 5, 2008 (for 415 variant airplanes). These 
service bulletins describe procedures for repetitive detailed 
inspections for signs of contamination, including corrosion/rust 
particles in the flange and housing of the rudder lower torque tube 
upper bearing. These service bulletins also describe procedures for 
bearing wear checks, and grease applications of the rudder lower torque 
tube upper bearing, and a rudder upper hinge gap check; and related 
investigative and corrective actions if necessary. Related 
investigative actions include inspecting old grease for signs of 
contamination, measuring the distance from the top of the bearing 
housing to the top of the lower bearing flange shoulder at multiple 
locations around the bearing, and doing a visual inspection to 
determine the cause of the excessive wear. Corrective actions include 
replacing the bearing(s) and adjusting the hinge gap. TCCA mandated the 
service information and issued Canadian airworthiness directive CF-
2008-29, dated August 20, 2008 (referred to after this as ``the 
MCAI''), to ensure the continued airworthiness of these airplanes in 
Canada.

FAA's Determination and Requirements of This 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 issuing 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.
    Therefore, we are issuing this AD to detect and correct corroded 
bearings which can lead to hinge deformation, and result in a rudder 
jam and consequent reduced controllability of the airplane. This AD 
requires accomplishing the actions specified in the service information 
described previously, except as discussed under ``Differences Between 
This AD and the Canadian Airworthiness Directive.''

Differences Between This AD and the Canadian Airworthiness Directive

    Bombardier Service Bulletin 215-3151, dated May 5, 2008 (for 215T 
variant airplanes); and Bombardier Service Bulletin 215-4394, dated May 
5, 2008 (for 415 variant airplanes) recommend accomplishing the 
required actions ``before and after every fire season,'' but we find 
this interval to be imprecise and vague. In developing appropriate 
compliance times for this AD, we considered not only the manufacturer's 
recommendation, but the degree of urgency associated with addressing 
the subject unsafe condition, the average utilization of the affected 
fleet, and the time necessary to perform the required actions. In light 
of all of these factors, we find that a 6-month repetitive interval for 
the required actions is an appropriate interval of time for affected 
airplanes to continue to operate without compromising safety. This 
difference has been coordinated with TCCA.

Interim Action

    We consider this proposed AD interim action. If final action is 
later identified, we might consider further rulemaking then.

Costs of Compliance

    None of the airplanes affected by this action are on the U.S. 
Register. All airplanes affected by this AD are currently operated by 
non-U.S. operators under foreign registry; therefore, they are not 
directly affected by this AD action. However, we consider this AD 
necessary to ensure that the unsafe condition is addressed if any 
affected airplane is imported and placed on the U.S. Register in the 
future.
    The following table provides the estimated costs to comply with 
this AD for any affected airplane that might be imported and placed on 
the U.S. Register in the future.

FAA's Determination of the Effective Date

    No airplane affected by this AD is currently on the U.S. Register. 
Therefore, providing notice and opportunity for public comment is 
unnecessary before this AD is issued, and this AD may be made effective 
in less than 30 days after it is published in the Federal Register.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments before it becomes effective. However, we invite 
you to send any written data, views, or arguments about this AD. Send 
your comments to an address listed under the ADDRESSES section. Include 
``Docket No. FAA-2009-0159; Directorate Identifier 2008-NM-175-AD'' at 
the beginning of your comments. We specifically invite comments on the 
overall regulatory, economic, environmental, and energy aspects of this 
AD. We will consider all comments received by the closing date and may 
amend this AD because of those comments.
    We will post all comments we receive, without change, to https://
www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

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 and placed it in the AD 
docket. See the ADDRESSES section for a location to examine the 
regulatory evaluation.
