SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That SNPRM published in the Federal Register on January 30, 2013 (78 FR 6254). The original NPRM (73 FR 32258, June 6, 2008) proposed to require repetitive operational tests of the engine E:\FR\FM\14MYR1.SGM 14MYR1 Federal Register / Vol. 78, No. 93 / Tuesday, May 14, 2013 / Rules and Regulations fuel suction feed of the fuel system, and other related testing if necessary. That SNPRM revised the NPRM by proposing to require repetitive operational tests and corrective actions if necessary. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM (78 FR 6254, January 30, 2013) or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. 28129 Costs of Compliance We estimate that this AD affects 827 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Cost per product Operational Test ........ Up to 12 work-hours × $85 per hour = $1,020 per engine, per test ...... Up to $2,040 ............. on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. We have received no definitive data that would enable us to provide a cost estimate for the on-condition actions specified in this AD. wreier-aviles on DSK5TPTVN1PROD with RULES 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 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, VerDate Mar<15>2010 15:25 May 13, 2013 Jkt 229001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Airplanes Federal Aviation Administration (FAA), Department of Transportation (DOT). ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL–600–2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by reports of two in-service incidents where the left main landing gear (MLG) failed to extend. This AD requires installing stopper plates on the aft uplock frames in the MLG bay adjacent to the right and left MLG uplock wreier-aviles on DSK5TPTVN1PROD with RULES SUMMARY: VerDate Mar<15>2010 15:25 May 13, 2013 Jkt 229001 assemblies. We are issuing this AD to prevent incorrect installation of the upper bolt in the MLG uplock assembly, which could prevent the MLG from extending and could adversely affect the safe landing of the airplane.

We have reviewed Bombardier Service Bulletin 601R–32–109, Revision A, dated February 26, 2013. In the NPRM (77 FR 63281, October 16, 2012), we referred to Bombardier Service Bulletin 601R–32–109, dated May 29, 2012, as the appropriate source of service information for doing the actions specified in the NPRM. Revision A of the service information adds information for parts that are listed in paragraph 1.G. ‘‘Material—Price and Availability,’’ and small editorial changes that do not have an effect on the technical content of the service information. We have updated paragraphs (g) and (j) of this AD to refer to Bombardier Service Bulletin 601R–32–109, Revision A, dated February 26, 2013. We have also added a new paragraph (h) to this AD to give credit for actions done before the effective date of this AD, using Bombardier Service Bulletin 601R–32– 109, dated May 29, 2012, and reidentified the subsequent paragraph identifiers accordingly. SUPPLEMENTARY INFORMATION: Comments Discussion We gave the public the opportunity to participate in developing this AD. We have considered the comments received. The National Transportation Safety Board supported the NPRM (77 FR 63281, October 16, 2012). This AD becomes effective June 18, 2013. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of June 18, 2013. DATES: You may examine the AD docket on the Internet at https:// www.regulations.gov or in person at the U.S. Department of Transportation, Docket Operations, M–30, West Building Ground Floor, Room W12–140, 1200 New Jersey Avenue SE., Washington, DC. ADDRESSES: FOR FURTHER INFORMATION CONTACT: We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to the specified products. That NPRM was published in the Federal Register on October 16, 2012 (77 FR 63281). That NPRM proposed to correct an unsafe condition for the specified products. The Mandatory Continuing Airworthiness Information (MCAI) states: There have been two reported in-service incidents where the left main landing gear (MLG) failed to extend. The investigation revealed that in both cases, the uplock assembly had been replaced prior to the inservice incidents and the upper bolt of the uplock assembly was incorrectly installed. The incorrect installation of the upper bolt resulted in the uplock assembly pivoting on the lower attachment bolt and preventing the MLG from extending under normal or alternate extension. The potential for an incorrect installation of the upper bolt could occur at both the left hand side (LHS) and/or the right hand side (RHS) MLG uplock assembly. Failure of the MLG to extend could adversely affect the safe landing of the aeroplane. This [Canadian] AD mandates the installation of stopper plates on the aft uplock frames in the MLG bay, adjacent to both the RHS and LHS MLG uplock assemblies, to prevent an incorrect installation of the MLG uplock assembly. You may obtain further information by examining the MCAI in the AD docket. PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 Request To Shorten the Compliance Time The Air Line Pilots Association International (ALPA) requested that the proposed compliance time in the NPRM (77 FR 63281, October 16, 2012) be shortened from ‘‘Within 5,500 flight hours or 48 months after the effective date of this AD, whichever occurs first . . . .’’ to ‘‘Within 2,400 flight hours or 24 months after the effective date of the AD, whichever occurs first . . . .’’ The ALPA based its suggested compliance time on the two reported in-service incidents and the potential safety implication of landing with an MLG fully or partially retracted. We do not agree with the request to shorten the compliance time. The proposed compliance time in the NPRM (77 FR 63281, October 16, 2012) was based on a risk assessment completed by the airplane manufacturer, Bombardier, Inc. The risk was conservatively assessed with a compliance time of 6,000 flight hours, based on the estimated release date of Bombardier service information.

Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 737-300, -400, and -500 series airplanes. This AD 
was prompted by reports of two in-service occurrences on Model 737-400 
airplanes of total loss of boost pump pressure of the fuel feed system, 
followed by loss of fuel system suction feed capability on one engine, 
and in-flight shutdown of the engine. This AD requires repetitive 
operational tests of the engine fuel suction feed of the fuel system, 
and corrective actions if necessary. We are issuing this AD to detect 
and correct loss of the engine fuel suction feed capability of the fuel 
system, which, in the event of total loss of the fuel boost pumps, 
could result in dual engine flameout, inability to restart the engines, 
and consequent forced landing of the airplane.

DATES: This AD is effective June 18, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of June 18, 
2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to include an AD that would apply to the specified 
products. That SNPRM published in the Federal Register on January 30, 
2013 (78 FR 6254). The original NPRM (73 FR 32258, June 6, 2008) 
proposed to require repetitive operational tests of the engine

[[Page 28129]]

fuel suction feed of the fuel system, and other related testing if 
necessary. That SNPRM revised the NPRM by proposing to require 
repetitive operational tests and corrective actions if necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM (78 FR 6254, January 30, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Costs of Compliance

    We estimate that this AD affects 827 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
            Action                  Labor cost             Cost per product            Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Operational Test..............  Up to 12 work-      Up to $2,040.................  Up to $1,687,080.
                                 hours x $85 per
                                 hour = $1,020 per
                                 engine, per test.
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in 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 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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2013-09-08 the Boeing Company: Amendment 39-17450; Docket No. FAA-
2008-0614; Directorate Identifier 2007-NM-351-AD.

(a) Effective Date

    This AD is effective June 18, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 737-300, -400, 
and -500 series airplanes, certificated in any category.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 2800, Aircraft Fuel System.

(e) Unsafe Condition

    This AD was prompted by reports of two in-service occurrences on 
Model 737-400 airplanes of total loss of boost pump pressure of the 
fuel feed system, followed by loss of fuel system suction feed 
capability on one engine, and in-flight shutdown of the engine. We 
are issuing this AD to detect and correct loss of the engine fuel 
suction feed capability of the fuel system, which in the event of 
total loss of the fuel boost pumps could result in dual engine 
flameout, inability to restart the engines, and consequent forced 
landing of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Operational Test and Corrective Actions

    Within 7,500 flight hours or 24 months after the effective date 
of this AD, whichever occurs first: Perform an operational test of 
the engine fuel suction feed of the fuel system, and do all 
applicable corrective actions, in accordance with the Accomplishment 
Instructions of Boeing Alert Service Bulletin 737-28A1407, dated May 
14, 2012. Do all applicable corrective actions before further 
flight. Repeat the operational test thereafter at intervals not to 
exceed 7,500 flight hours or 24 months, whichever occurs first. 
Thereafter, except as provided in paragraph (h) of this AD, no 
alternative procedures or repetitive test intervals are allowed.

(h) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in the Related Information 
section of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
