Discussion Transport Canada Civil Aviation, which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2012–18, dated May 29, 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: It was discovered that a number of primary wheels on the HSTA P/N [part number] 601R92305–5 (or vendor P/N 8396–4) had burr marks. Investigation revealed that the burr marks were a result of incorrectly using the manufacturing process. In addition, some rings that were fitted on the primary wheel shaft were found cracked. If not corrected, this condition may lead to a disconnect of the pitch trim surface and subsequent loss of pitch control. This [Canadian] AD mandates the removal of the affected units that have the above described manufacturing defect. Corrective actions include replacement of certain HSTAs. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier has issued Service Bulletin 601R–27–159, dated June 15, 2011. The actions described in this service bulletin 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. Differences Between This AD and the MCAI or Service Information While the Applicability of Transport Canada Civil Aviation (TCCA) Canadian AD CF–2012–18, dated May 29, 2012, is Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 7003 and subsequent, equipped with HSTAs having P/N 601R92305–5 or vendor P/ N 8396–4, with serial numbers (S/N)s 287, 724, 813, 841, 998, 1031, 1035, 1049, 1053, 1067, 1068, 1136, 1252, 1268, 1303, 1319, 1338, 1354, 1374, 1378, 1445, 1470, 1498, 1513, 1546, 1632, 1736, 1766, 1846, 1849, 2002 through 2009, 2011, 2013 through 2016, 2019, 2020, and 2022; the applicability of this AD is for all Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This has been coordinated with TCCA. While TCCA Canadian AD CF–2012– 18, dated May 29, 2012, does not allow for a records review to verify part numbers, paragraph (g) of this AD does allow for a records review to be used to verify part numbers. Costs of Compliance We estimate that this proposed AD affects 575 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Replacement ........................... 19 work-hours × $85 per hour = $1,615 ................................ $0 $1,615 $928,625 ehiers on DSK2VPTVN1PROD with PROPOSALS-1 Authority for This Rulemaking Regulatory Findings 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. 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.

AD 2009–24– 07 currently requires repetitive lubrications of the right and left main landing gear (MLG) forward trunnion pins. AD 2009–24–07 also requires an inspection for discrepancies of the transition radius of the MLG forward trunnion pins, and corrective actions if necessary. For certain airplanes, AD 2009–24–07 requires repetitive detailed inspections for discrepancies (including finish damage, corrosion, pitting, and base metal scratches) of the transition radius of the left and right MLG trunnion pins, and corrective action if necessary. Replacing or overhauling the trunnion pins would terminate the actions required by AD 2009–24–07. This proposed AD would add airplanes to the applicability of AD 2009–24–07. We are proposing this AD to prevent stress corrosion cracking of the forward trunnion pins, which could result in fracture of the pins and consequent collapse of the MLG.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This proposed AD was prompted by reports of burr marks on 
the primary wheels, and cracked rings on the primary wheel shaft, on 
certain horizontal stabilizer trim actuators (HSTAs). This proposed AD 
would require replacing certain HSTAs. We are proposing this AD to 
prevent burr marks on the primary wheels, and cracked rings on the 
primary wheel shaft, on certain HSTAs, which may lead to a disconnect 
of the pitch trim surface and subsequent loss of pitch control, 
resulting in loss of control of the airplane.

Discussion

    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian Airworthiness Directive CF-2012-18, 
dated May 29, 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:

    It was discovered that a number of primary wheels on the HSTA P/
N [part number] 601R92305-5 (or vendor P/N 8396-4) had burr marks. 
Investigation revealed that the burr marks were a result of 
incorrectly using the manufacturing process. In addition, some rings 
that were fitted on the primary wheel shaft were found cracked. If 
not corrected, this condition may lead to a disconnect of the pitch 
trim surface and subsequent loss of pitch control.
    This [Canadian] AD mandates the removal of the affected units 
that have the above described manufacturing defect.

Corrective actions include replacement of certain HSTAs. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Bombardier has issued Service Bulletin 601R-27-159, dated June 15, 
2011. The actions described in this service bulletin 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.

Differences Between This AD and the MCAI or Service Information

    While the Applicability of Transport Canada Civil Aviation (TCCA) 
Canadian AD CF-2012-18, dated May 29, 2012, is Bombardier, Inc. Model 
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes, serial numbers 
7003 and subsequent, equipped with HSTAs having P/N 601R92305-5 or 
vendor P/N 8396-4, with serial numbers (S/N)s 287, 724, 813, 841, 998, 
1031, 1035, 1049, 1053, 1067, 1068, 1136, 1252, 1268, 1303, 1319, 1338, 
1354, 1374, 1378, 1445, 1470, 1498, 1513, 1546, 1632, 1736, 1766, 1846, 
1849, 2002 through 2009, 2011, 2013 through 2016, 2019, 2020, and 2022; 
the applicability of this AD is for all Bombardier, Inc. Model CL-600-
2B19 (Regional Jet Series 100 & 440) airplanes. This has been 
coordinated with TCCA.
    While TCCA Canadian AD CF-2012-18, dated May 29, 2012, does not 
allow for a records review to verify part numbers, paragraph (g) of 
this AD does allow for a records review to be used to verify part 
numbers.

Costs of Compliance

    We estimate that this proposed AD affects 575 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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 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.

    This AD was prompted by reports of burr marks on the primary 
wheels, and cracked rings on the primary wheel shaft, on certain 
HSTAs. We are issuing this AD to prevent burr marks on the primary 
wheels, and cracked rings on the primary wheel shaft, on certain 
HSTAs, which may lead to a disconnect of the pitch trim surface and 
subsequent loss of pitch control, resulting in loss of control of 
the airplane.

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspection

    Within 1,000 flight hours or 4 months after the effective date 
of this AD, whichever occurs first, inspect to determine if any HSTA 
having part number (P/N) 601R92305-5 or vendor P/N 8396-4, with 
serial numbers (S/N)s 287, 724, 813, 841, 998, 1031, 1035, 1049, 
1053, 1067, 1068, 1136, 1252, 1268, 1303, 1319, 1338, 1354, 1374,

installed. A review of airplane maintenance records is acceptable in 
lieu of this inspection if the part number of the HSTA can be 
conclusively determined from that review.

of this AD, whichever occurs first, replace the affected HSTAs 
identified in paragraph (g) of this AD, with a serviceable HSTA, in 
accordance with the Accomplishment Instructions of Bombardier 
Service Bulletin 601R-27-159, dated June 15, 2011.
