Discussion The Civil Aviation Authority of New Zealand (CAA), which is the aviation authority for New Zealand, has issued DCA/750XL/2, dated September 30, 2004 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: To prevent electrical malfunction from causing damage to the wiring that may result in arcing or fire, accomplish Pacific Aerospace Service Bulletin PACSB/XL/008. The MCAI requires the addition and replacement of certain pitot heat sensor circuit breakers and the addition of a cooling fan circuit fuse. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Pacific Aerospace Corporation Limited has issued Mandatory Service Bulletin PACSB/XL/008, dated July 8, 2004. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. E:\FR\FM\15FEP1.SGM 15FEP1 8832 Federal Register / Vol. 73, No. 32 / Friday, February 15, 2008 / Proposed Rules FAA’s Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the 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 We have reviewed the MCAI and related service information and, in general, agree with their substance. But we might have found it necessary to use different words from those in the MCAI to ensure the AD is clear for U.S. operators and is enforceable. In making these changes, we do not intend to differ substantively from the information provided in the MCAI and related service information. We might also have proposed different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are highlighted in a NOTE within the proposed AD. rwilkins on PROD1PC63 with PROPOSALS Costs of Compliance Based on the service information, we estimate that this proposed AD would affect about 7 products of U.S. registry. We also estimate that it would take about 1.5 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $181 per product. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $2,107, or $301 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 VerDate Aug<31>2005 17:07 Feb 14, 2008 Jkt 214001 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); 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 proposed AD and placed it in the AD docket.

ACTION: Notice of proposed rulemaking (NPRM). rwilkins on PROD1PC63 with PROPOSALS AGENCY: SUMMARY: We propose to adopt a new airworthiness directive (AD) for certain Boeing Model 737–600, –700, –700C, –800 and –900 series airplanes. This proposed AD would require an inspection of the escape slides for the forward and aft entry and service doors to determine the part number and service bulletin number stenciled on the escape slide girt, and modification of the escape slide assemblies. This proposed AD also would require concurrent modification of the escape slide latch assembly; concurrent inspection of the escape slides to determine the part number and service bulletin number stenciled on the escape slide girts, and replacement of the trigger housing on the regulator valve with improved trigger housing if necessary; and concurrent replacement of the rod in the pilot valve regulator with a new improved rod; as applicable. VerDate Aug<31>2005 17:07 Feb 14, 2008 Jkt 214001 This proposed AD results from reports that certain escape slides did not automatically inflate when deployed or after the manual inflation cable was pulled. We are proposing this AD to prevent failure of an escape slide to inflate when deployed, which could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or crewmembers.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We have received reports indicating that Goodrich 5A3307 series escape slides did not automatically inflate when deployed on Boeing Model 737– 600, –700, –700C, –800 and –900 series airplanes. On some of these airplanes, the escape slides did not inflate even after the manual inflation cable was pulled and the firing cable was pulled out of the valve regulator assembly. Investigation revealed that these escape slides did not inflate because the piston rod was incorrectly installed in the valve regulator assembly of the escape slide. The same valve regulator is also used on Goodrich 5A3086 and 5A3088 series escape slides. If the rod is installed upside down, the valve regulator assembly can be charged but the rod will prevent the regulator from activating when the firing cable is pulled. On other airplanes, the escape slides did not automatically inflate when deployed, but did inflate after the manual inflation cable was pulled. Investigation revealed that these escape slides did not automatically inflate because there was insufficient force to pull the inflation cable from the valve, due to the trigger housing cover deflecting the inflation cable. The failure of an escape slide to inflate when deployed, if not corrected, could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or crewmembers. Other Related Rulemaking On July 13, 2001, we issued AD 2001– 15–01, amendment 39–12335 (66 FR 38361, July 24, 2001), applicable to certain Boeing Model 727 and 737 airplanes; and Model 757–200, 757– 200CB, and 757–300 series airplanes. That AD requires modification of the latch assembly of the escape slides. For Model 737–600, –700, and –800 series airplanes, that AD also requires installation of a cover assembly on the trigger housing of the inflation cylinder on the escape slides.

Discussion

    The Civil Aviation Authority of New Zealand (CAA), which is the 
aviation authority for New Zealand, has issued DCA/750XL/2, dated 
September 30, 2004 (referred to after this as ``the MCAI''), to correct 
an unsafe condition for the specified products. The MCAI states:

    To prevent electrical malfunction from causing damage to the 
wiring that may result in arcing or fire, accomplish Pacific 
Aerospace Service Bulletin PACSB/XL/008.

    The MCAI requires the addition and replacement of certain pitot 
heat sensor circuit breakers and the addition of a cooling fan circuit 
fuse.
    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Pacific Aerospace Corporation Limited has issued Mandatory Service 
Bulletin PACSB/XL/008, dated July 8, 2004. The actions described in 
this service information are intended to correct the unsafe condition 
identified in the MCAI.

[[Page 8832]]

FAA's Determination and Requirements of the 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 this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the 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

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have proposed different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 7 products of U.S. registry. We also estimate that 
it would take about 1.5 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $80 per 
work-hour. Required parts would cost about $181 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $2,107, or $301 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 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); 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 proposed AD and placed it in the AD docket.
