Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion In April 1992, the FAA issued a document titled ‘‘Criteria for Assessing Transport Turbojet Fleet Thrust Reverser Safety.’’ This document is based upon the premise that no failure of thrust reverser components anticipated to occur in service should prevent continued safe flight and landing of an airplane. In order to comply with the criteria in the document, Boeing recommends incorporating a wiring modification of the thrust reverser system on McDonnell Douglas Model DC–8–62, DC–8–63, DC– 8–62F, and DC–8–63F airplanes. Based upon the Boeing safety evaluations, we have determined that the existing thrust reverser systems on these airplanes do not adequately preclude inadvertent deployment of the thrust reversers. Inadvertent deployment of the thrust reversers during takeoff or landing could result in loss of control of the airplane. Relevant Service Information We have reviewed McDonnell Douglas DC–8 Service Bulletin 78–95, Revision 2, dated March 10, 1971; and Revision 1, dated December 29, 1970. The service bulletins describe procedures for either revising the wiring for the engine thrust brake circuit and indicating circuit and doing other specified actions, or rerouting the wiring at plug P1–1762A on the electrical power center (EPC) generator control panel, depending on the configuration of the airplane. The other specified actions include modifying and reidentifying a nameplate and accomplishing the adjustment/test of the thrust reverser system. For certain airplanes, the other specified actions also include installing a new bracket, terminal boards, and clamps. E:\FR\FM\19OCP1.SGM 19OCP1 Federal Register / Vol. 71, No. 202 / Thursday, October 19, 2006 / Proposed Rules Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously, except as discussed under ‘‘Difference Between the Proposed AD and Service Bulletin.’’ Difference Between the Proposed AD and Service Bulletin Although the service bulletins do not recommend a compliance time for accomplishing the modification, we have coordinated a compliance time of 27 months with Boeing. In developing an appropriate compliance time for this proposed AD, we considered not only the manufacturer’s recommendation, but the degree of urgency associated with addressing the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the modification. In light of all of these factors, we find a compliance time of 27 months for completing the required actions to be warranted, in that it represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. cprice-sewell on PROD1PC66 with PROPOSALS Costs of Compliance There are about 70 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 45 airplanes of U.S. registry. The proposed actions would take between 1 and 5 work hours per airplane, depending on airplane configuration, at an average labor rate of $80 per work hour. For a certain airplane configuration, required parts would cost about $9 per airplane. For a certain other airplane configuration, required parts would cost about $2,825 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is between $4,005 and $145,125, or between $89 and $3,225 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. VerDate Aug<31>2005 15:01 Oct 18, 2006 Jkt 211001 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under the 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 proposed AD and placed it in the AD docket. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Safety.

Discussion

    In April 1992, the FAA issued a document titled ``Criteria for 
Assessing Transport Turbojet Fleet Thrust Reverser Safety.'' This 
document is based upon the premise that no failure of thrust reverser 
components anticipated to occur in service should prevent continued 
safe flight and landing of an airplane. In order to comply with the 
criteria in the document, Boeing recommends incorporating a wiring 
modification of the thrust reverser system on McDonnell Douglas Model 
DC-8-62, DC-8-63, DC-8-62F, and DC-8-63F airplanes. Based upon the 
Boeing safety evaluations, we have determined that the existing thrust 
reverser systems on these airplanes do not adequately preclude 
inadvertent deployment of the thrust reversers. Inadvertent deployment 
of the thrust reversers during takeoff or landing could result in loss 
of control of the airplane.

Relevant Service Information

    We have reviewed McDonnell Douglas DC-8 Service Bulletin 78-95, 
Revision 2, dated March 10, 1971; and Revision 1, dated December 29, 
1970. The service bulletins describe procedures for either revising the 
wiring for the engine thrust brake circuit and indicating circuit and 
doing other specified actions, or rerouting the wiring at plug P1-1762A 
on the electrical power center (EPC) generator control panel, depending 
on the configuration of the airplane. The other specified actions 
include modifying and reidentifying a nameplate and accomplishing the 
adjustment/test of the thrust reverser system. For certain airplanes, 
the other specified actions also include installing a new bracket, 
terminal boards, and clamps.

[[Page 61691]]

Accomplishing the actions specified in the service information is 
intended to adequately address the unsafe condition.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other airplanes 
of this same type design. For this reason, we are proposing this AD, 
which would require accomplishing the actions specified in the service 
information described previously, except as discussed under 
``Difference Between the Proposed AD and Service Bulletin.''

Difference Between the Proposed AD and Service Bulletin

    Although the service bulletins do not recommend a compliance time 
for accomplishing the modification, we have coordinated a compliance 
time of 27 months with Boeing. In developing an appropriate compliance 
time for this proposed AD, we considered not only the manufacturer's 
recommendation, but the degree of urgency associated with addressing 
the subject unsafe condition, the average utilization of the affected 
fleet, and the time necessary to perform the modification. In light of 
all of these factors, we find a compliance time of 27 months for 
completing the required actions to be warranted, in that it represents 
an appropriate interval of time for affected airplanes to continue to 
operate without compromising safety.

Costs of Compliance

    There are about 70 airplanes of the affected design in the 
worldwide fleet. This proposed AD would affect about 45 airplanes of 
U.S. registry. The proposed actions would take between 1 and 5 work 
hours per airplane, depending on airplane configuration, at an average 
labor rate of $80 per work hour. For a certain airplane configuration, 
required parts would cost about $9 per airplane. For a certain other 
airplane configuration, required parts would cost about $2,825 per 
airplane. Based on these figures, the estimated cost of the proposed AD 
for U.S. operators is between $4,005 and $145,125, or between $89 and 
$3,225 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.
