ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires repetitive detailed inspections for disbonding and tearing and measurements for wear of the internal diameter (ID) of the Karon-lined bushings of the bulkhead support jackscrew fitting and of the jackscrew fitting of the horizontal stabilizer; and reinstallation of the horizontal stabilizer trim actuator (HSTA) after inspection and measurement; and if necessary, replacement of the bushings with new bushings and all applicable related investigative and corrective actions. This AD was prompted by a report indicating that a Karon-lined bushing with the liner broken into five pieces was found during a scheduled inspection of the HSTA components; the broken liner had worn and disbonded from the bushing. We are issuing this AD to detect and correct discrepancies of the HSTA attachment locations, which could result in reduced structural integrity of the horizontal stabilizer and consequent loss of controllability of the airplane.

SUPPLEMENTARY INFORMATION: Conclusion Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to the specified products. That NPRM published in the Federal Register on December 1, 2010 (75 FR 74668, January 18, 2011). That NPRM proposed to require repetitive detailed inspections for disbonding and tearing and measurements for wear of the internal diameter (ID) of the Karon-lined bushings of the bulkhead support jackscrew fitting and of the jackscrew fitting of the horizontal stabilizer; repetitive installations of the horizontal stabilizer trim actuator (HSTA); and if necessary, replacement of the bushings with new bushings and all applicable related investigative and corrective actions. Comments We gave the public the opportunity to participate in developing this AD. We have considered the comments received. Boeing and American Airlines support the NPRM. Clarification of AD Summary We determined that the requirement specified in the Summary section of the NPRM for ‘‘repetitive installations of the HSTA’’ should be more clearly described as ‘‘reinstallation of the HSTA after inspection and measurement.’’ The Summary section of this AD has been revised accordingly. No change has been PO 00000 Frm 00016 Fmt 4700 Sfmt 4700 We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance We estimate that this AD affects 145 airplanes of U.S. registry. We also estimate that it will take about 7 workhours per product to comply with the detailed inspection, measurement, and installation in this AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $86,275, or $595 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 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), (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 E:\FR\FM\10MRR1.SGM 10MRR1 Federal Register / Vol. 76, No. 47 / Thursday, March 10, 2011 / Rules and Regulations under the criteria of the Regulatory Flexibility Act.

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD requires repetitive detailed inspections 
for disbonding and tearing and measurements for wear of the internal 
diameter (ID) of the Karon-lined bushings of the bulkhead support 
jackscrew fitting and of the jackscrew fitting of the horizontal 
stabilizer; and reinstallation of the horizontal stabilizer trim 
actuator (HSTA) after inspection and measurement; and if necessary, 
replacement of the bushings with new bushings and all applicable 
related investigative and corrective actions. This AD was prompted by a 
report indicating that a Karon-lined bushing with the liner broken into 
five pieces was found during a scheduled inspection of the HSTA 
components; the broken liner had worn and disbonded from the bushing. 
We are issuing this AD to detect and correct discrepancies of the HSTA 
attachment locations, which could result in reduced structural 
integrity of the horizontal stabilizer and consequent loss of 
controllability of the airplane.

DATES: This AD is effective April 14, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of April 14, 
2011.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
the specified products. That NPRM published in the Federal Register on 
December 1, 2010 (75 FR 74668, January 18, 2011). That NPRM proposed to 
require repetitive detailed inspections for disbonding and tearing and 
measurements for wear of the internal diameter (ID) of the Karon-lined 
bushings of the bulkhead support jackscrew fitting and of the jackscrew 
fitting of the horizontal stabilizer; repetitive installations of the 
horizontal stabilizer trim actuator (HSTA); and if necessary, 
replacement of the bushings with new bushings and all applicable 
related investigative and corrective actions.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comments received. Boeing and American 
Airlines support the NPRM.

Clarification of AD Summary

    We determined that the requirement specified in the Summary section 
of the NPRM for ``repetitive installations of the HSTA'' should be more 
clearly described as ``reinstallation of the HSTA after inspection and 
measurement.'' The Summary section of this AD has been revised 
accordingly. No change has been made to other sections of this AD in 
this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD as proposed.

Costs of Compliance

    We estimate that this AD affects 145 airplanes of U.S. registry. We 
also estimate that it will take about 7 work-hours per product to 
comply with the detailed inspection, measurement, and installation in 
this AD. The average labor rate is $85 per work-hour. Based on these 
figures, we estimate the cost of this AD to the U.S. operators to be 
$86,275, or $595 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

    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),
    (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
