SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 with an AD for all McDonnell Douglas Model MD–90–30 airplanes. That action, published in the Federal Register on December 14, 2004 (69 FR 74463), proposed to require a general visual inspection in the electrical/electronics (E/E) compartment for damage of the wire bundle and aft right radio rack structure at station 160.000, and corrective actions if necessary. That action also proposed to require modifying the radio rack structure and wire bundle routing. 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. Change to This AD We have changed the manufacturer name on the service bulletin citation in this AD from McDonnell Douglas to Boeing to reflect current guidelines established by the Office of the Federal Register for material incorporated by reference. There are about 105 airplanes of the affected design in the worldwide fleet. This AD will affect about 21 airplanes of U.S. registry. The required actions will take about 5 work hours per airplane, at an average labor rate of $65 per work hour. Required parts will cost about $3,479 per airplane. Based on these figures, the estimated cost of the 14:59 Mar 01, 2005 PART 39—AIRWORTHINESS DIRECTIVES Authority for This Rulemaking I 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.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all 
McDonnell Douglas Model MD-90-30 airplanes. This AD requires a general 
visual inspection in the electrical/electronics (E/E) compartment for 
damage of the wire bundle and aft right radio rack structure at station 
160.000, and corrective actions if necessary. This AD also requires 
modifying the radio rack structure and wire bundle routing. This AD is 
prompted by a report indicating that burnt wiring was discovered in the 
wire bundle at station 160.000 in the E/E compartment. We are issuing 
this AD to detect and correct chafing of the wire bundle at station 
160.000 against the support bracket located on the aft right radio 
rack, which could lead to shorted or burnt wires and consequent smoke 
and fire in the E/E compartment.

DATES: This AD becomes effective April 6, 2005.

SUPPLEMENTARY INFORMATION: The FAA proposed to amend 14 CFR Part 39 
with an AD for all McDonnell Douglas Model MD-90-30 airplanes. That 
action, published in the Federal Register on December 14, 2004 (69 FR 
74463), proposed to require a general visual inspection in the 
electrical/electronics (E/E) compartment for damage of the wire bundle 
and aft right radio rack structure at station 160.000, and corrective 
actions if necessary. That action also proposed to require modifying 
the radio rack structure and wire bundle routing.

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.

Change to This AD

    We have changed the manufacturer name on the service bulletin 
citation in this AD from McDonnell Douglas to Boeing to reflect current 
guidelines established by the Office of the Federal Register for 
material incorporated by reference.

Costs of Compliance

    There are about 105 airplanes of the affected design in the 
worldwide fleet. This AD will affect about 21 airplanes of U.S. 
registry. The required actions will take about 5 work hours per 
airplane, at an average labor rate of $65 per work hour. Required parts 
will cost about $3,479 per airplane. Based on these figures, the 
estimated cost of the AD for U.S. operators is $79,884, or $3,804 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.
