Discussion The Civil Aviation Authority (CAA), which is the airworthiness authority for the United Kingdom, notified us that an unsafe condition may exist on all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. The CAA advises that a Model Jetstream 4101 airplane had a total electrical failure just as the airplane landed. Although investigations did not uncover all mechanisms that contributed to the total electrical failure, investigators established that a significant contributory factor was a chafed exciter wire to the positive terminal of the starter-generator. The current routing of the small wiring at the starter-generator terminal block has the potential for incorrect routing and possible chafing and shorting against the stud of terminal ‘‘B.’’ The starter-generator is currently removed for overhaul at 600-flight-hour intervals, and the wires can be damaged or misrouted during removal and reinstallation. This condition, if not corrected, could result in total electrical failure and consequent reduced controllability of the airplane. Relevant Service Information BAE Systems (Operations) Limited has issued Service Bulletin J41–24–041, dated May 10, 2004. The service bulletin describes procedures for modifying the wiring of the startergenerator terminal block. For airplanes on which modification JM41360 (a modification to the electrical wiring) has not been incorporated, the procedures include splicing and rerouting the wires. For airplanes on which modification JM41360 has been incorporated, the procedures include rerouting the wires. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The CAA mandated the service information and issued British airworthiness directive G–2005–0006, dated February 7, 2005, to ensure the continued airworthiness of these airplanes in the United Kingdom. PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 FAA’s Determination and Requirements of the Proposed AD This airplane model is manufactured in the United Kingdom and is type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the CAA has kept the FAA informed of the situation described above. We have examined the CAA’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance This proposed AD would affect about 57 airplanes of U.S. registry. The proposed actions would take about 10 work hours per airplane, at an average labor rate of $65 per work hour. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $37,050, or $650 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.

SUPPLEMENTARY INFORMATION: Background The basic purpose of the SSI program (title XVI of the Social Security Act (the Act)) is to ensure a minimum level of income to people who are age 65 or older, or blind or disabled, and who have limited income and resources. Section 1611 of the Act provides that SSI payments can be made only to people who have income and resources below specified amounts. Therefore, the amount of income and resources a person has is a major factor in deciding whether the person can receive SSI benefits and in computing the amount of the benefits. Public Law 108–203, the SSPA of 2004, was enacted on March 2, 2004. Sections 430, 435, and 436 of this law affect how income and resources are determined in the SSI program.

Discussion

    The Civil Aviation Authority (CAA), which is the airworthiness 
authority for the United Kingdom, notified us that an unsafe condition 
may exist on all BAE Systems (Operations) Limited (Jetstream) Model 
4101 airplanes. The CAA advises that a Model Jetstream 4101 airplane 
had a total electrical failure just as the airplane landed. Although 
investigations did not uncover all mechanisms that contributed to the 
total electrical failure, investigators established that a significant 
contributory factor was a chafed exciter wire to the positive terminal 
of the starter-generator. The current routing of the small wiring at 
the starter-generator terminal block has the potential for incorrect 
routing and possible chafing and shorting against the stud of terminal 
``B.'' The starter-generator is currently removed for overhaul at 600-
flight-hour intervals, and the wires can be damaged or misrouted during 
removal and reinstallation. This condition, if not corrected, could 
result in total electrical failure and consequent reduced 
controllability of the airplane.

Relevant Service Information

    BAE Systems (Operations) Limited has issued Service Bulletin J41-
24-041, dated May 10, 2004. The service bulletin describes procedures 
for modifying the wiring of the starter-generator terminal block. For 
airplanes on which modification JM41360 (a modification to the 
electrical wiring) has not been incorporated, the procedures include 
splicing and re-routing the wires. For airplanes on which modification 
JM41360 has been incorporated, the procedures include re-routing the 
wires. Accomplishing the actions specified in the service information 
is intended to adequately address the unsafe condition. The CAA 
mandated the service information and issued British airworthiness 
directive G-2005-0006, dated February 7, 2005, to ensure the continued 
airworthiness of these airplanes in the United Kingdom.

FAA's Determination and Requirements of the Proposed AD

    This airplane model is manufactured in the United Kingdom and is 
type certificated for operation in the United States under the 
provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 
21.29) and the applicable bilateral airworthiness agreement. Pursuant 
to this bilateral airworthiness agreement, the CAA has kept the FAA 
informed of the situation described above. We have examined the CAA's 
findings, evaluated all pertinent information, and determined that we 
need to issue an AD for airplanes of this type design that are 
certificated for operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 57 airplanes of U.S. registry. 
The proposed actions would take about 10 work hours per airplane, at an 
average labor rate of $65 per work hour. Based on these figures, the 
estimated cost of the proposed AD for U.S. operators is $37,050, or 
$650 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.

[[Page 52949]]

    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.
