Airworthiness Directives; Bombardier, Inc. Airplanes, 79329-79333 [2013-31185]

Download as PDF Federal Register / Vol. 78, No. 250 / Monday, December 30, 2013 / Proposed Rules DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–1065; Directorate Identifier 2011–NM–230–AD] RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede an existing airworthiness directive (AD) that applies to certain Bombardier, Inc. Model CL–600–1A11 (CL–600), CL– 600–2A12 (CL–601), and CL–600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. The existing AD currently requires operators to assign serial numbers or part numbers to certain landing gear parts; and to establish the number of landings on the parts, if necessary. The existing AD also requires operators to revise the Airworthiness Limitations Section (ALS) of the Instructions for Continued Airworthiness (ICA) to reflect the new life limits of the landing gear parts. Since we issued that AD, additional landing gear parts have been identified that need serialization. This proposed AD would add airplanes to the applicability; require operators to assign serial numbers or part numbers to certain additional landing gear parts, to establish the number of landings on the parts, if necessary; and record in all required airplane technical records and manuals the new part numbers, serial numbers, and landings assigned to these parts. We are proposing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear. DATES: We must receive comments on this proposed AD by February 13, 2014.

SUPPLEMENTARY INFORMATION: 79329 personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion On July 11, 2005, we issued AD 2005– 15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005). That AD required actions intended to address an unsafe condition on the products listed above. Since we issued AD 2005–15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005), Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, has issued Canadian Airworthiness Directives CF–2003–18R2, dated September 28, 2011; CF–2003–20R1, dated September 28, 2011; and CF– 2003–21R2, dated September 28, 2011; (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: Certain landing gear parts that are listed in the aeroplane model Airworthiness Limitations Section, as safe life items with structural life limits, could be rotable and may not have been serialized, making tracking difficult. This [Canadian airworthiness] directive mandates that such parts be serialized. This [Canadian airworthiness] directive also provides the procedure to determine the number of landings for those parts where the service history cannot be established. * * * * * [T]his [Canadian Airworthiness] directive * * * mandate[s] serialization of * * * additional landing gear parts. Comments Invited This proposed AD would also add airplanes to the applicability. The unsafe condition is using life-limited landing gear parts beyond their safe-life limits, which could lead to collapse of the landing gear. You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA–2013–1065. We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2013–1065; Directorate Identifier 2011–NM–230–AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD based on those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any Relevant Service Information Bombardier, Inc. has issued the following service bulletins. • Bombardier Service Bulletin 600– 0710, Revision 03, dated May 9, 2011, including Appendix 1, dated May 9, 2011, and Service Bulletin Information Sheet, dated July 6, 2010 (for Model CL– 600–1A11 (CL–600) airplanes). • Bombardier Service Bulletin 601– 0546, Revision 03, dated May 9, 2011, including Appendix 1, dated May 9, 2011, and Service Bulletin Information Sheet, dated July 6, 2010 (for Model CL– 600–2A12 (CL–601) airplanes and Model CL–600–2B16 (CL–601–3A and CL–601–3R Variants) airplanes).

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. tkelley on DSK3SPTVN1PROD with PROPOSALS Differences Between This Proposed AD and the MCAI or Service Information For Model CL–600–2B16 (CL–604 Variant) airplanes, the MCAI specifies serial numbers 5301 through 5595 inclusive; however, the actions of the MCAI address only serial numbers 5301 through 5573 inclusive, 5579, and 5595. Consequently, we have specified the proposed applicability as serial numbers 5301 to 5573 inclusive, 5579, and 5595. We have coordinated this difference with TCCA. Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 419 products of U.S. registry. The actions that are required by AD 2005–15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005), and retained in this proposed AD take up to 13 workhours per product, at an average labor rate of $85 per work hour. Based on these figures, the estimated cost of the currently required actions is $1,105 per product. We estimate that it would take about 9 work-hours per product to comply with the new basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $320,535, or $765 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, VerDate Mar<15>2010 16:26 Dec 27, 2013 Jkt 232001 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 proposed 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. PO 00000 Frm 00003 Fmt 4702 Sfmt 4702 § 39.13 [Amended] 2. The FAA amends § 39.13 by removing airworthiness directive (AD) 2005–15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005), and adding the following new AD: ■ Bombardier, Inc.: Docket No. FAA–2013– 1065; Directorate Identifier 2011–NM– 230–AD. (a) Comments Due Date We must receive comments by February 13, 2014. (b) Affected ADs This AD supersedes AD 2005–15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005). (c) Applicability This AD applies to Bombardier, Inc. airplanes, certificated in any category, as identified in paragraphs (c)(1) through (c)(4) of this AD. (1) Model CL–600–1A11 (CL–600) airplanes, serial numbers 1004 through 1085 inclusive. (2) Model CL–600–2A12 (CL–601) airplanes, serial numbers 3001 through 3066 inclusive; (3) Model CL–600–2B16 (CL–601–3A and CL–601–3R Variants) airplanes, serial numbers 5001 through 5194 inclusive. (4) Model CL–600–2B16 (CL–604 Variant) airplanes, serial numbers 5301 through 5573 inclusive, 5579, and 5595. (5) This AD requires revisions to certain operator maintenance documents to include new actions (e.g., inspections). Compliance with these actions is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this AD, the operator may not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (r) of this AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure. (d) Subject Air Transport Association (ATA) of America Code 32, Landing Gear. (e) Reason This AD was prompted by reports that landing gear parts that have safe-life limits but do not have serial numbers or part numbers can be removed from one landing gear and re-installed on another, making tracking difficult. We are issuing this AD to prevent life-limited landing gear parts from being used beyond their safe-life limits, which could lead to collapse of the landing gear. (f) Compliance You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done. E:\FR\FM\30DEP1.SGM 30DEP1 Federal Register / Vol. 78, No. 250 / Monday, December 30, 2013 / Proposed Rules (g) Retained Requirement To Add Serial Numbers (S/Ns) or Part Numbers (P/Ns) This paragraph restates the actions required by paragraph (f) of AD 2005–15–04, Amendment 39–14193 (70 FR 43032, July 26, 2005), with revised affected airplanes.

ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 2000–12– 12, for certain Airbus Model A300, A300–600, and A310 series airplanes. AD 2000–12–12 currently requires inspecting to detect cracks in the lower spar axis of the nacelle pylon between ribs 9 and 10, and repair if necessary. AD 2000–12–12 also provides for optional modification of the pylon, which terminates the inspections for Model A300 series airplanes. Since we issued AD 2000–12–12, we have received reports of cracking of the lower pylon spar after accomplishing the existing modification and have determined that shorter initial and repetitive inspection compliance times are necessary to address the identified unsafe condition. This proposed AD would reduce the initial and repetitive inspection compliance times. We are proposing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the lower spar of the nacelle pylon.

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-600-1A11 (CL-
600), CL-600-2A12 (CL-601), and CL-600-2B16 (CL-601-3A, CL-601-3R, and 
CL-604 Variants) airplanes. The existing AD currently requires 
operators to assign serial numbers or part numbers to certain landing 
gear parts; and to establish the number of landings on the parts, if 
necessary. The existing AD also requires operators to revise the 
Airworthiness Limitations Section (ALS) of the Instructions for 
Continued Airworthiness (ICA) to reflect the new life limits of the 
landing gear parts. Since we issued that AD, additional landing gear 
parts have been identified that need serialization. This proposed AD 
would add airplanes to the applicability; require operators to assign 
serial numbers or part numbers to certain additional landing gear 
parts, to establish the number of landings on the parts, if necessary; 
and record in all required airplane technical records and manuals the 
new part numbers, serial numbers, and landings assigned to these parts. 
We are proposing this AD to prevent life-limited landing gear parts 
from being used beyond their safe-life limits, which could lead to 
collapse of the landing gear.

DATES: We must receive comments on this proposed AD by February 13, 
2014.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    On July 11, 2005, we issued AD 2005-15-04, Amendment 39-14193 (70 
FR 43032, July 26, 2005). That AD required actions intended to address 
an unsafe condition on the products listed above.
    Since we issued AD 2005-15-04, Amendment 39-14193 (70 FR 43032, 
July 26, 2005), Transport Canada Civil Aviation (TCCA), which is the 
airworthiness authority for Canada, has issued Canadian Airworthiness 
Directives CF-2003-18R2, dated September 28, 2011; CF-2003-20R1, dated 
September 28, 2011; and CF-2003-21R2, dated September 28, 2011; 
(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:

    Certain landing gear parts that are listed in the aeroplane 
model Airworthiness Limitations Section, as safe life items with 
structural life limits, could be rotable and may not have been 
serialized, making tracking difficult. This [Canadian airworthiness] 
directive mandates that such parts be serialized. This [Canadian 
airworthiness] directive also provides the procedure to determine 
the number of landings for those parts where the service history 
cannot be established.
* * * * *
    [T]his [Canadian Airworthiness] directive * * * mandate[s] 
serialization of * * * additional landing gear parts.

    This proposed AD would also add airplanes to the applicability. The 
unsafe condition is using life-limited landing gear parts beyond their 
safe-life limits, which could lead to collapse of the landing gear. You 
may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No. FAA-
2013-1065.

Relevant Service Information

    Bombardier, Inc. has issued the following service bulletins.
     Bombardier Service Bulletin 600-0710, Revision 03, dated 
May 9, 2011, including Appendix 1, dated May 9, 2011, and Service 
Bulletin Information Sheet, dated July 6, 2010 (for Model CL-600-1A11 
(CL-600) airplanes).
     Bombardier Service Bulletin 601-0546, Revision 03, dated 
May 9, 2011, including Appendix 1, dated May 9, 2011, and Service 
Bulletin Information Sheet, dated July 6, 2010 (for Model CL-600-2A12 
(CL-601) airplanes and Model CL-600-2B16 (CL-601-3A and CL-601-3R 
Variants) airplanes).

[[Page 79330]]

     Bombardier Service Bulletin 604-32-014, Revision 02, dated 
May 9, 2011, including Appendix 1, dated May 9, 2011, and Service 
Bulletin Information Sheet, dated July 6, 2010 (for Model CL-600-2B16 
(CL-604 Variant) airplanes).
    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.

Differences Between This Proposed AD and the MCAI or Service 
Information

    For Model CL-600-2B16 (CL-604 Variant) airplanes, the MCAI 
specifies serial numbers 5301 through 5595 inclusive; however, the 
actions of the MCAI address only serial numbers 5301 through 5573 
inclusive, 5579, and 5595. Consequently, we have specified the proposed 
applicability as serial numbers 5301 to 5573 inclusive, 5579, and 5595. 
We have coordinated this difference with TCCA.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 419 products of U.S. registry.
    The actions that are required by AD 2005-15-04, Amendment 39-14193 
(70 FR 43032, July 26, 2005), and retained in this proposed AD take up 
to 13 work-hours per product, at an average labor rate of $85 per work 
hour. Based on these figures, the estimated cost of the currently 
required actions is $1,105 per product.
    We estimate that it would take about 9 work-hours per product to 
comply with the new basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of the proposed AD on U.S. operators to be $320,535, or $765 
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 proposed 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.

    (1) Model CL-600-1A11 (CL-600) airplanes, serial numbers 1004 
through 1085 inclusive.
    (2) Model CL-600-2A12 (CL-601) airplanes, serial numbers 3001 
through 3066 inclusive;
    (3) Model CL-600-2B16 (CL-601-3A and CL-601-3R Variants) 
airplanes, serial numbers 5001 through 5194 inclusive.
    (4) Model CL-600-2B16 (CL-604 Variant) airplanes, serial numbers 
5301 through 5573 inclusive, 5579, and 5595.
    (5) This AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections). Compliance 
with these actions is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by this AD, the operator may not be able to 
accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (r) of this AD. The request should include a 
description of changes to the required actions that will ensure the 
continued damage tolerance of the affected structure.

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
Gear.

(e) Reason

    This AD was prompted by reports that landing gear parts that 
have safe-life limits but do not have serial numbers or part numbers 
can be removed from one landing gear and re-installed on another, 
making tracking difficult. We are issuing this AD to prevent life-
limited landing gear parts from being used beyond their safe-life 
limits, which could lead to collapse of the landing gear.

(f) Compliance

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

[[Page 79331]]

(g) Retained Requirement To Add Serial Numbers (S/Ns) or Part Numbers 
(P/Ns)

    This paragraph restates the actions required by paragraph (f) of 
AD 2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005), with 
revised affected airplanes. Except for Model CL-600-2B16 airplanes 
having serial numbers 5514 through 5595 inclusive: At the applicable 
compliance time specified in paragraph (g)(1), (g)(2), or (g)(3) of 
this AD, add serial numbers and part numbers, as applicable, to the 
parts identified in the applicable service bulletin specified in 
paragraph (g)(1), (g)(2), or (g)(3) of this AD. Do all actions in 
accordance with the applicable service bulletin specified in 
paragraph (g)(1), (g)(2), or (g)(3) of this AD.
    (1) For parts identified in Bombardier Service Bulletin 600-
0710, Revision 01, dated December 15, 2003; and Bombardier Service 
Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a 
compliance time of ``five years for the parts listed in Part A'': 
Within 60 months after August 30, 2005 (the effective date of AD 
2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
    (2) For parts identified in Bombardier Service Bulletin 600-
0710, Revision 01, dated December 15, 2003; and Bombardier Service 
Bulletin 601-0546, Revision 01, dated December 15, 2003; as having a 
compliance time of ``ten years for the parts listed in Part B'': 
Within 120 months after August 30, 2005 (the effective date of AD 
2005-15-04, Amendment 39-14193 (70 FR 43032, July 26, 2005)).
    (3) For parts identified in Bombardier Service Bulletin 604-32-
014, dated May 31, 2002, as having a compliance time of ``no later 
than a calendar time of 8 years'': Within 96 months after August 30, 
2005 (the effective date of AD 2005-15-04, Amendment 39-14193 (70 FR 
43032, July 26, 2005)).
    Note 1 to paragraph (g) of this AD: The Bombardier service 
bulletins refer to the Messier-Dowty service bulletins in table 1 to 
paragraph (g) of this AD as additional sources of service 
information for adding part numbers or serial numbers by vibro-
peening the numbers on main landing gear (MLG) and nose landing gear 
(NLG) components that do not have them; and for determining the 
number of landings for parts without a part number or serial number 
on which the time since new (TSN) and cycles since new (CSN) have 
not been tracked.
