E:\FR\FM\14DER1.SGM 14DER1 73922 Federal Register / Vol. 70, No. 239 / Wednesday, December 14, 2005 / Rules and Regulations Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that would apply to certain EMBRAER Model ERJ 170 airplanes. That NPRM was published in the Federal Register on September 19, 2005 (70 FR 57215). That NPRM proposed to require doing a general visual inspection of the passenger seat track attachments to determine if the attachment rod is installed and to check the torque value of the attachment bolts, and doing any corrective actions if necessary. Comments We provided the public the opportunity to participate in the development of this AD. We received no comments on the NPRM or on the determination of the cost to the public. Conclusion We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance This AD affects about 43 airplanes of U.S. registry. The inspection takes about 1 work hour per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is $2,795, or $65 per airplane. The modification, if necessary, takes about 2 work hours per airplane, at an average labor rate of $65 per work hour. Required parts are about $860 per airplane. Based on these figures, the estimated cost of the modification is $990 per airplane, if necessary. 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. VerDate Aug<31>2005 15:23 Dec 13, 2005 Jkt 208001 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 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule. AGENCY: SUMMARY: The FAA is superseding an existing airworthiness directive (AD), which applies to certain Sabreliner Model NA–265–40, NA–265–50, NA– 265–60, NA–265–70, and NA–265–80 series airplanes. That AD currently requires repetitive inspections for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib, and corrective actions if necessary. This new AD expands the applicability of the existing AD and requires new repetitive inspections for fuel leaks of the front and rear spars of the wing, and for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel rib. This AD also requires related investigative and corrective actions, if necessary. This AD results from reports of cracking in the upper and lower flanges of the front and rear spars of the wing near the wing center section, and in the lugs on the rear spar. We are VerDate Aug<31>2005 15:23 Dec 13, 2005 Jkt 208001 73923 issuing this AD to detect and correct cracking or other discrepancies in these areas, which could result in structural failure of the wing.

Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 73–18–03, amendment 39–3201 (43 FR 19208, May 4, 1978). The existing AD applies to certain Rockwell International Model NA–265– 40, NA–265–50, NA–265–60, NA–265– 70, and NA–265–80 series airplanes. That NPRM was published in the Federal Register on September 14, 2005 (70 FR 54318). (A correction of that NPRM was published in the Federal Register on September 30, 2005 (70 FR 57222).) That NPRM proposed to expand the applicability of the existing AD and require new repetitive inspections for fuel leaks of the front and rear spars of the wing, and for discrepancies in the front and rear spars of the wing in the area of the wing center section, and in the lugs on the rear spar and wing trailing edge panel Authority for This Rulemaking PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 Comments We provided the public the opportunity to participate in the development of this AD.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain EMBRAER Model ERJ 170 airplanes. This AD requires doing a 
general visual inspection of the passenger seat track attachments to 
determine if the attachment rod is installed and to check the torque 
value of the attachment bolts, and doing any corrective actions if 
necessary. This AD results from the finding of missing rods, which 
attach the passenger seat tracks to the airplane structure to absorb 
loads. We are issuing this AD to detect and correct missing attachment 
rods, which could result in reducing the ability of the seat to 
withstand a hard landing or rejected takeoff and possible injury to 
passengers.

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that would apply to certain EMBRAER Model 
ERJ 170 airplanes. That NPRM was published in the Federal Register on 
September 19, 2005 (70 FR 57215). That NPRM proposed to require doing a 
general visual inspection of the passenger seat track attachments to 
determine if the attachment rod is installed and to check the torque 
value of the attachment bolts, and doing any corrective actions if 
necessary.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We received no comments on the NPRM or on the 
determination of the cost to the public.

Conclusion

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

Costs of Compliance

    This AD affects about 43 airplanes of U.S. registry. The inspection 
takes about 1 work hour per airplane, at an average labor rate of $65 
per work hour. Based on these figures, the estimated cost of the AD for 
U.S. operators is $2,795, or $65 per airplane.
    The modification, if necessary, takes about 2 work hours per 
airplane, at an average labor rate of $65 per work hour. Required parts 
are about $860 per airplane. Based on these figures, the estimated cost 
of the modification is $990 per airplane, if necessary.

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 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
