AGENCY: VerDate Aug<31>2005 15:59 Jan 19, 2007 Jkt 211001 ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as reports of interference between the wing spar lower boom and the wheel fairing attaching screw. We are issuing this AD to require actions to correct the unsafe condition on these products. This AD becomes effective February 26, 2007. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of February 26, 2007. ADDRESSES: You may examine the AD docket on the Internet at https:// dms.dot.gov or in person at the Docket Management Facility, U.S. Department of Transportation, 400 Seventh Street, SW., Nassif Building, Room PL–401, Washington, DC. FOR FURTHER INFORMATION CONTACT: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329– 4059; fax: (816) 329–4090. SUPPLEMENTARY INFORMATION: DATES: Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. Discussion 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 PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 Register on November 22, 2006 (71 FR 67506). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that there are reports of interference between the wing spar lower boom and the wheel fairing attaching screw causing an unsafe condition. The interference could, if left uncorrected, reduce the fatigue life of the wing spar with potentially catastrophic results. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comment received. Comment Issue: Cost of Compliance EADS SOCATA states: Application of SB10–148–57 does not require specific part. So, the cost is negligible. EADS SOCATA estimates that it would take 1 work-hour to inspect and displace the screw. If repair is necessary, the cost depends on the damage. Our cost estimate included both the inspection and screw displacement costs as well as repair costs. We developed the repair cost estimate based on the information provided and assumed the worst case scenario if a repair was required. Since EADS SOCATA did not provide an estimate (work-hours or parts cost) if a repair is required and the FAA is required to provide this estimate to the public, we are keeping the language the same as the NPRM to account for worst case repair situations. Conclusion We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD as proposed. Differences Between This 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 required different actions in this AD from those in the MCAI in order to follow FAA policies. Any such differences are described in a separate paragraph of the AD, and take precedence over the actions copied from the MCAI. E:\FR\FM\22JAR1.SGM 22JAR1 Federal Register / Vol. 72, No. 13 / Monday, January 22, 2007 / Rules and Regulations Costs of Compliance We estimate that this AD will affect 270 products of U.S. registry. We also estimate that it will take about 15 workhours per product to comply with this AD. The average labor rate is $80 per work-hour. Required parts will cost about $15,000 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $4,374,000, or $16,200 per product. sroberts on PROD1PC70 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 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 this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866; (2) Is not a ‘‘significant rule’’ under 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 AD and placed it in the AD Docket.

SUPPLEMENTARY INFORMATION Streamlined Issuance of AD The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products. This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles. Discussion 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 November 28, 2006 (71 FR 68762). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that there was a report of a master cylinder yoke failure. The AD requirements are to detect defective yokes on aircraft and replace them. The aim of this AD is to ensure that normal braking is available at any time to prevent possible runway excursions in the event of failure of the master cylinder yoke. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. EADS SOCATA gave comments addressing the following: Comment Issue No. 1: Cost of Compliance EADS SOCATA states: The proposed AD specifies that: ‘‘Required parts would cost about $600’’. $600 corresponds to the cost of the replacement of all (4) the master cylinder yokes. According to EADS Socata experience, operators complying with EADS Socata SB70–136–32 PO 00000 Frm 00012 Fmt 4700 Sfmt 4700 had to replace only one yoke in the worst case. The FAA does not agree. We are using the worst case scenario of all four yokes being replaced. If an operator needs to replace fewer yokes, the cost will be less. Comment Issue No. 2: Applicability EADS SOCATA states: We propose to specify: ‘‘This AD applies to SOCATA Model TBM700 airplanes, all serial number, certificated in any category equipped with master cylinder assembly part number ZOO.N6068757280 or ZOO.N6068757281’’. Indeed, the supplier of the master cylinder assembly could change in the future and aircraft equipped with another part number would not be concerned. The FAA does not agree. Including the part number in the applicability is redundant. Per the AD, the operator has to verify whether the applicable part number is installed and, if so, take appropriate action. If a different part number from a different supplier is installed, then the AD does not apply. Comment Issue No. 3: Actions and Compliance, Paragraphs (e)(1)(ii)(B) and (e)(2) EADS SOCATA states: Paragraph (e)(1)(ii)(B): Yokes part number ZOO.N7134732200 (delivered since January 2006) can also be installed on aircraft. Socata decides to produce itself yoke part number T700A324004810000 for logistic reasons but the design of this yokes is the same as Parker yoke part number ZOO.N7134732200. Paragraph (e)(2): During installation of master cylinder yoke part number ZOO.N7134732200 or installation of master cylinder assembly part number ZOO.N6068757280 or ZOO.N6068757281, we propose to check the yokes in accordance with SB70–136–32 only if these parts were delivered new before January 2006. The FAA does not agree. Since these parts are not serialized and tracked, there would be no way of knowing if the part was delivered before or after January 2006. In addition, EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70–136, ATA No. 32, dated December 2005, requires installation of yoke part number T700A324004810000. If an operator wants to use a different part numbered component and can show that it provides an acceptable level of safety, the operator can make a request to the FAA to approve an alternative method of compliance (AMOC) using the procedures in 14 CFR part 39 and this AD.

SUPPLEMENTARY INFORMATION:

Streamlined Issuance of AD

    The FAA is implementing a new process for streamlining the issuance 
of ADs related to MCAI. The streamlined process will allow us to adopt 
MCAI safety requirements in a more efficient manner and will reduce 
safety risks to the public. This process continues to follow all FAA AD 
issuance processes to meet legal, economic, Administrative Procedure 
Act, and Federal Register requirements. We also continue to meet our 
technical decision-making responsibilities to identify and correct 
unsafe conditions on U.S.-certificated products.
    This AD references the MCAI and related service information that we 
considered in forming the engineering basis to correct the unsafe 
condition. The AD contains text copied from the MCAI and for this 
reason might not follow our plain language principles.

Discussion

    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 November 22, 2006 
(71 FR 67506). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states that there are reports of 
interference between the wing spar lower boom and the wheel fairing 
attaching screw causing an unsafe condition. The interference could, if 
left uncorrected, reduce the fatigue life of the wing spar with 
potentially catastrophic results.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.

Comment Issue: Cost of Compliance

    EADS SOCATA states:

    Application of SB10-148-57 does not require specific part. So, 
the cost is negligible. EADS SOCATA estimates that it would take 1 
work-hour to inspect and displace the screw. If repair is necessary, 
the cost depends on the damage.

    Our cost estimate included both the inspection and screw 
displacement costs as well as repair costs. We developed the repair 
cost estimate based on the information provided and assumed the worst 
case scenario if a repair was required. Since EADS SOCATA did not 
provide an estimate (work-hours or parts cost) if a repair is required 
and the FAA is required to provide this estimate to the public, we are 
keeping the language the same as the NPRM to account for worst case 
repair situations.

Conclusion

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

Differences Between This 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 required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
described in a separate paragraph of the AD, and take precedence over 
the actions copied from the MCAI.

[[Page 2607]]

Costs of Compliance

    We estimate that this AD will affect 270 products of U.S. registry. 
We also estimate that it will take about 15 work-hours per product to 
comply with this AD. The average labor rate is $80 per work-hour. 
Required parts will cost about $15,000 per product. Where the service 
information lists required parts costs that are covered under warranty, 
we have assumed that there will be no charge for these parts. As we do 
not control warranty coverage for affected parties, some parties may 
incur costs higher than estimated here. Based on these figures, we 
estimate the cost of this AD to the U.S. operators to be $4,374,000, or 
$16,200 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 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 this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866;
    (2) Is not a ``significant rule'' under 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 AD and placed it in the AD Docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at https://
dms.dot.gov; or in person at the Docket Management Facility between 9 
a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD

2007-02-04 SOCATA-Groupe Aerospatiale: Amendment 39-14891; Docket 
No. FAA-2006-26236; Directorate Identifier 2006-CE-66-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective February 
26, 2007.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to SOCATA Models TB 20 and TB 21 airplanes, 
serial numbers 1 through 9999 without repair REP 20.031 implemented 
on both sides, certificated in any category.

Reason

    (d) The mandatory continuing airworthiness information (MCAI) 
states there are reports of interference between the wing spar lower 
boom and the wheel fairing attaching screw causing an unsafe 
condition. The interference could, if left uncorrected, reduce the 
fatigue life of the wing spar with potentially catastrophic results. 
The MCAI requires inspections and repairs as necessary to correct 
this unsafe condition.

Actions and Compliance

    (e) Unless already done, do the following actions.
    (1) Within the next 100 hours time-in-service or 12 months after 
the effective date of this AD, whichever occurs first, perform an 
inspection of the wing spar lower boom and repair it as necessary, 
in accordance with the accomplishment instructions of the EADS 
SOCATA TB Aircraft Mandatory Service Bulletin SB 10-148, ATA No. 57, 
dated December 2005.
    (2) If defect dimensions exceed the acceptable values given in 
the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB 10-148, 
ATA No. 57, dated December 2005, or if the defect is not located in 
areas depicted in figure 2 of the EADS SOCATA TB Aircraft Mandatory 
Service Bulletin SB 10-148, ATA No. 57, dated December 2005, then 
the Type 1 or Type 2 repair solutions are not applicable. A written 
report shall be sent to the manufacturer as mentioned in section A.5 
of the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB 10-148, 
ATA No. 57, dated December 2005. In this case, all flight is 
prohibited until EADS SOCATA provides a repair solution or otherwise 
agrees to further flight.
