ACTION: Final rule. AGENCY: SUMMARY: The FAA is adopting a new airworthiness directive (AD) for Boeing Model 737–300, –400, and –500 series airplanes modified in accordance with STC ST00127BO. This AD requires installation of bonding straps to the safe side harnesses of the digital transient suppression device of the fuel quantity indicating system. This AD is prompted by the results of fuel system reviews conducted by the STC holder. We are issuing this AD to prevent unsafe levels of current or energy from entering the fuel tank, due to hot short faults or threat conditions associated with the safe side harness assembly, which could result in a fire or explosion of the fuel tank. DATES: This AD becomes effective April 18, 2005. The incorporation by reference of Goodrich Service Bulletin 737–300766– 28–2, Revision 2, dated July 28, 2004, as listed in the AD, is approved by the Director of the Federal Register as of April 18, 2005.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 with an AD for Boeing Model 737–300, –400, and –500 series airplanes modified in accordance with STC ST00127BO. That action, published in the Federal Register on December 16, 2004 (69 FR 75280), proposed to require installation of bonding straps to the safe side harnesses of the digital transient suppression device of the fuel quantity indicating system. Comments We provided the public the opportunity to participate in the development of this AD. No comments have been submitted on the proposed AD 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 There are about 404 airplanes of the affected design in the worldwide fleet. This AD affects about 2 airplanes of U.S. registry. The actions take about 9 work hours per airplane, at an average labor rate of $65 per work hour. For airplanes equipped with a Cinch rectangular PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 connector, required parts will cost about $1,650 per airplane. For all other airplanes, required parts will cost about $1,500 per airplane. Based on these figures, the estimated cost of the AD for U.S. operators is between $2,085 and $2,235 per airplane. 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. See the ADDRESSES section for a location to examine the regulatory evaluation.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
Boeing Model 737-300, -400, and -500 series airplanes modified in 
accordance with STC ST00127BO. This AD requires installation of bonding 
straps to the safe side harnesses of the digital transient suppression 
device of the fuel quantity indicating system. This AD is prompted by 
the results of fuel system reviews conducted by the STC holder. We are 
issuing this AD to prevent unsafe levels of current or energy from 
entering the fuel tank, due to hot short faults or threat conditions 
associated with the safe side harness assembly, which could result in a 
fire or explosion of the fuel tank.

DATES: This AD becomes effective April 18, 2005.
    The incorporation by reference of Goodrich Service Bulletin 737-
300766-28-2, Revision 2, dated July 28, 2004, as listed in the AD, is 
approved by the Director of the Federal Register as of April 18, 2005.

ADDRESSES: For service information identified in this AD, contact

Massachusetts 01803; telephone (781) 238-7184; fax (781) 238-7170.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 
with an AD for Boeing Model 737-300, -400, and -500 series airplanes 
modified in accordance with STC ST00127BO. That action, published in 
the Federal Register on December 16, 2004 (69 FR 75280), proposed to 
require installation of bonding straps to the safe side harnesses of 
the digital transient suppression device of the fuel quantity 
indicating system.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been submitted on the proposed 
AD 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

    There are about 404 airplanes of the affected design in the 
worldwide fleet. This AD affects about 2 airplanes of U.S. registry. 
The actions take about 9 work hours per airplane, at an average labor 
rate of $65 per work hour. For airplanes equipped with a Cinch 
rectangular connector, required parts will cost about $1,650 per 
airplane. For all other airplanes, required parts will cost about 
$1,500 per airplane. Based on these figures, the estimated cost of the 
AD for U.S. operators is between $2,085 and $2,235 per airplane.

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