[Docket No. FAA–2013–0687; Directorate Identifier 2012–NM–118–AD; Amendment 39–17767; AD 2014–04–08] SUPPLEMENTARY INFORMATION: RIN 2120–AA64 We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Bombardier, Inc. Model CL– 600–2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM published in the Federal Register on August 13, 2013 (78 FR 49227). The NPRM was prompted by reports of burr marks on the primary wheels, and cracked rings on the primary wheel shaft, on certain HSTAs. The NPRM proposed to require replacing 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. Transport Canada Civil Aviation (TCCA), 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: Discussion Airworthiness Directives; Bombardier, Inc. Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. mstockstill on DSK4VPTVN1PROD with RULES AGENCY: SUMMARY: We are adopting a new airworthiness directive (AD) for all Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This 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).

FOR FURTHER INFORMATION CONTACT: Cesar Gomez, Aerospace Engineer, Airframe and Mechanical Systems VerDate Mar<15>2010 16:16 Feb 28, 2014 Jkt 232001 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 examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/ #!documentDetail;D=FAA-2013-06870003. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. The following presents the comment received on the proposal (78 FR 49227, August 13, 2013) and the FAA’s response to the comment. PO 00000 Frm 00013 Fmt 4700 Sfmt 4700 11691 Request To Revise the Applicability Air Wisconsin Airlines requested that we limit the applicability of the NPRM (78 FR 49227, August 13, 2013) to Model CL–6–2B19 (Regional Jet Series 100 & 440) airplanes ‘‘equipped with HSTAs having part number (P/N) 601R92305–5 or vendor P/N 8396–4, with serial numbers (S/N)s as identified in paragraph (g) of this AD.’’ We disagree with the commenter’s request. The intent of the applicability in the NPRM (78 FR 49227, August 13, 2013) and this final rule was to capture all possible airplanes that could have an affected HSTA, or on which an affected HSTA could be installed in the future. This issue was coordinated with TCCA. The parts installation limitation, which applies to all Model CL–600– 2B19 (Regional Jet Series 100 & 440) airplanes, is retained in this final rule. This provision matches the intent of Canadian AD CF–2012–18, dated May 29, 2012. We have made no changes to this final rule in this regard. Also, we have specified serial numbers 7003 and subsequent (which includes all serial numbers) in paragraph (c) in this final rule, which corresponds with the Applicability of Canadian AD CF–2012–18, dated May 29, 2012. Conclusion We reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this AD as proposed except for minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM (78 FR 49227, August 13, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 49227, August 13, 2013). Costs of Compliance We estimate that this AD affects 575 airplanes of U.S. registry. We also estimate that it will take about 19 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts will cost about $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $928,625, or $1,615 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 E:\FR\FM\03MRR1.SGM 03MRR1 11692 Federal Register / Vol. 79, No. 41 / Monday, March 3, 2014 / Rules and Regulations 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 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 this AD: 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 2002–23–19 applied to all Dassault Aviation Model FALCON 2000 series airplanes. The NPRM published in the Federal Register on July 12, 2013 (78 FR 41882). The NPRM proposed to revise the maintenance program to incorporate new or revised maintenance requirements and airworthiness limitations. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0156, dated August 23, 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 airworthiness limitations and maintenance requirements for the Falcon 2000 type design are included in Dassault Aviation Falcon 2000 (F2000) Aircraft Maintenance Manual (AMM) chapter 5–40 and are approved by the European Aviation Safety Agency (EASA). EASA issued AD 2008–0221 [https://ad.easa.europa.eu/blob/ easa_ad_2008_0221_Corrected.pdf/AD_ 2008–0221_1] to require accomplishment of the maintenance tasks, and implementation of the airworthiness limitations, as specified in Dassault Aviation F2000 AMM chapter 5– 40 at revision 12. Since that [EASA] AD was issued, Dassault Aviation have issued F2000 AMM chapter 5– 40 at revision 17, which introduces new or more restrictive maintenance requirements and/or airworthiness limitations. PO 00000 Frm 00015 Fmt 4700 Sfmt 4700 11693 Dassault Aviation AMM chapter 5–40 revision 17 contains among other changes the following requirements: —Inspection and test of horizontal stabilizer jackscrew; —Operational test of voltage monitoring circuits; —Upgrade of screwjack of flap actuators from the older to the latest -3 version; —Revised Time Between Overhaul for screwjack of flap actuators -3 version; —Revised interval for checking the screw/ nut play on screwjack of flap actuators -3 version; —Removal of service life limit for screwjack of flap actuators; —Test of flap asymmetry protection system.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This 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 AD requires 
replacing 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.

DATES: This AD becomes effective April 7, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 7, 
2014.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Bombardier, Inc. Model 
CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on August 13, 2013 (78 FR 49227). The 
NPRM was prompted by reports of burr marks on the primary wheels, and 
cracked rings on the primary wheel shaft, on certain HSTAs. The NPRM 
proposed to require replacing 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.
    Transport Canada Civil Aviation (TCCA), 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 
examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0687-0003.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received. The following 
presents the comment received on the proposal (78 FR 49227, August 13, 
2013) and the FAA's response to the comment.

Request To Revise the Applicability

    Air Wisconsin Airlines requested that we limit the applicability of 
the NPRM (78 FR 49227, August 13, 2013) to Model CL-6-2B19 (Regional 
Jet Series 100 & 440) airplanes ``equipped with HSTAs having part 
number (P/N) 601R92305-5 or vendor P/N 8396-4, with serial numbers (S/
N)s as identified in paragraph (g) of this AD.''
    We disagree with the commenter's request. The intent of the 
applicability in the NPRM (78 FR 49227, August 13, 2013) and this final 
rule was to capture all possible airplanes that could have an affected 
HSTA, or on which an affected HSTA could be installed in the future. 
This issue was coordinated with TCCA.
    The parts installation limitation, which applies to all Model CL-
600-2B19 (Regional Jet Series 100 & 440) airplanes, is retained in this 
final rule. This provision matches the intent of Canadian AD CF-2012-
18, dated May 29, 2012. We have made no changes to this final rule in 
this regard.
    Also, we have specified serial numbers 7003 and subsequent (which 
includes all serial numbers) in paragraph (c) in this final rule, which 
corresponds with the Applicability of Canadian AD CF-2012-18, dated May 
29, 2012.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 49227, August 13, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 49227, August 13, 2013).

Costs of Compliance

    We estimate that this AD affects 575 airplanes of U.S. registry.
    We also estimate that it will take about 19 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $928,625, or $1,615 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

[[Page 11692]]

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 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 this AD:
    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.

reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

2014-04-08 Bombardier, Inc.: Amendment 39-17767. Docket No. FAA-
2013-0687; Directorate Identifier 2012-NM-118-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective April 7, 
2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all Bombardier, Inc. Model CL-600-2B19 
(Regional Jet Series 100 & 440) airplanes, certificated in any 
category, serial numbers 7003 and subsequent.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Reason

    This 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). 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already 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, 
1378, 1445, 1470, 1498, 1513, 1546, 1632, 1736, 1766, 1846, 1849, 
2002 through 2009, 2011, 2013 through 2016, 2019, 2020, and 2022 is 
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.

(h) Replacement

    Within 1,000 flight hours or 4 months after the effective date 
of this AD, whichever occurs first, replace any affected HSTA 
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.

(i) Parts Installation Limitations

    As of the effective date of this AD, no person may install any 
HSTA having P/N 601R92305-5 or vendor P/N 8396-4 with a serial 
number listed in paragraph (g) of this AD, unless the serial number 
has the suffix ``A'' beside it.
