Examining the Docket You may examine the AD docket on the Internet at http://dms.dot.gov, or in person at the Docket Management Facility office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The Docket Management Facility office (telephone (800) 647–5227) is located on the plaza level of the Nassif Building at the DOT street address stated in the ADDRESSES section. Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion We have received a report indicating that a Gulfstream Model GV–SP series airplane temporarily lost normal braking function during landing rollout on a pre-delivery flight. The flightcrew received no indication of failure or degradation within the braking system prior to the loss of braking. Normal braking function was recovered after the wheel speed decreased through 50 knots. Investigation revealed that the temporary loss of braking was caused by incorrect capacitors installed in the antiskid control unit (ACU). The manufacturer of the ACUs has identified a range of serial numbers that may have this defect. Loss of normal braking function, if not corrected, could result in a runway overrun that could cause injury to flightcrew or passengers or damage to the airplane. Relevant Service Information We have reviewed Gulfstream G500 Customer Bulletin 17, dated August 12, VerDate Aug<31>2005 17:03 Dec 08, 2005 Jkt 208001 2005 (for Model GV–SP (G500) series airplanes); and Gulfstream G550 Customer Bulletin 17, dated August 12, 2005 (for Model GV–SP (G550) series airplanes). The customer bulletins describe procedures for inspecting the ACU in the right electronics equipment rack to determine the serial number (S/N). If the ACU unit has an affected S/ N, the customer bulletins also describe procedures for replacing the ACU unit with a new part having a S/N outside the affected range or with a serviceable part having a re-identified S/N. 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 ‘‘Differences Between the Proposed AD and Customer Bulletins.’’ Differences Between the AD and Customer Bulletins Although the customer bulletins recommend accomplishing the inspection within 60 days, we have determined that extending the compliance time will not adversely affect safety for the affected fleet. In developing an appropriate compliance time for this AD, we considered the degree of urgency associated with the subject unsafe condition, the average utilization of the affected fleet, and the time necessary to perform the inspection (1 hour). In light of all of these factors, we find that a 90-day compliance time represents an appropriate interval of time for affected airplanes to continue to operate without compromising safety. This difference has been coordinated with Gulfstream. Operators should note that, although the Accomplishment Instructions of the referenced customer bulletins describe procedures for submitting a sheet recording compliance with the customer bulletins, this AD would not require those actions. We do not need this information from operators. Clarification of Customer Bulletins The accomplishment instructions of the referenced customer bulletins specify contacting Gulfstream if technical assistance is required. We have included a note in this AD to PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 clarify that any deviation from the instructions in the applicable customer bulletin must be approved as an alternative method of compliance under paragraph (h) of this AD. Costs of Compliance There are about 20 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 15 airplanes of U.S. registry. The proposed inspection would take about 1 work hour 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 $975, or $65 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 E:\FR\FM\09DEP1.SGM 09DEP1 Federal Register / Vol. 70, No. 236 / Friday, December 9, 2005 / Proposed Rules AD docket.

SUPPLEMENTARY INFORMATION: Part 260 of the Board’s regulations deals generally with administrative review of denials of claims or requests for waiver of recovery of overpayments under the Railroad Retirement Act (RRA). Part 320 deals with the same matters under the Railroad Unemployment Insurance Act (RUIA). The Board proposes to amend these parts to state that, at the discretion of the hearings officer, hearings held during the appeal process may be conducted in person, by telephone conference call, or by video teleconferencing. Previously, the regulations only allowed for hearings to be held in person or by telephone conference call. Specifically, the Board proposes to amend §§ 260.5(i) and 320.22 to state that a proposed hearing may be held in person, by telephone conference call, or by video teleconferencing. These sections also state that if an individual objects to having a hearing by video teleconferencing, the hearings officer will find the individual had good cause for objecting to the time or place of the hearing and will reschedule the individual for either a telephone or an in person hearing for the appeal. The regulation also amends sections 260.5(l) and 320.25 to state that the hearings officer determines whether a hearing is scheduled for a telephone conference call, video teleconferencing, or in person. The Board, with the concurrence of the Office of Management and Budget, has determined that this is not a significant regulatory action under Executive Order 12866. Therefore, no regulatory impact analysis is required. There are no changes to the information collections associated with parts 260 and 320.

Discussion

    We have received a report indicating that a Gulfstream Model GV-SP 
series airplane temporarily lost normal braking function during landing 
rollout on a pre-delivery flight. The flightcrew received no indication 
of failure or degradation within the braking system prior to the loss 
of braking. Normal braking function was recovered after the wheel speed 
decreased through 50 knots. Investigation revealed that the temporary 
loss of braking was caused by incorrect capacitors installed in the 
anti-skid control unit (ACU). The manufacturer of the ACUs has 
identified a range of serial numbers that may have this defect. Loss of 
normal braking function, if not corrected, could result in a runway 
overrun that could cause injury to flightcrew or passengers or damage 
to the airplane.

Relevant Service Information

    We have reviewed Gulfstream G500 Customer Bulletin 17, dated August 
12, 2005 (for Model GV-SP (G500) series airplanes); and Gulfstream G550 
Customer Bulletin 17, dated August 12, 2005 (for Model GV-SP (G550) 
series airplanes). The customer bulletins describe procedures for 
inspecting the ACU in the right electronics equipment rack to determine 
the serial number (S/N). If the ACU unit has an affected S/N, the 
customer bulletins also describe procedures for replacing the ACU unit 
with a new part having a S/N outside the affected range or with a 
serviceable part having a re-identified S/N. 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 
``Differences Between the Proposed AD and Customer Bulletins.''

Differences Between the AD and Customer Bulletins

    Although the customer bulletins recommend accomplishing the 
inspection within 60 days, we have determined that extending the 
compliance time will not adversely affect safety for the affected 
fleet. In developing an appropriate compliance time for this AD, we 
considered the degree of urgency associated with the subject unsafe 
condition, the average utilization of the affected fleet, and the time 
necessary to perform the inspection (1 hour). In light of all of these 
factors, we find that a 90-day compliance time represents an 
appropriate interval of time for affected airplanes to continue to 
operate without compromising safety. This difference has been 
coordinated with Gulfstream.
    Operators should note that, although the Accomplishment 
Instructions of the referenced customer bulletins describe procedures 
for submitting a sheet recording compliance with the customer 
bulletins, this AD would not require those actions. We do not need this 
information from operators.

Clarification of Customer Bulletins

    The accomplishment instructions of the referenced customer 
bulletins specify contacting Gulfstream if technical assistance is 
required. We have included a note in this AD to clarify that any 
deviation from the instructions in the applicable customer bulletin 
must be approved as an alternative method of compliance under paragraph 
(h) of this AD.

Costs of Compliance

    There are about 20 airplanes of the affected design in the 
worldwide fleet. This proposed AD would affect about 15 airplanes of 
U.S. registry. The proposed inspection would take about 1 work hour 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 
$975, or $65 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

Applicability

    (c) This AD applies to Gulfstream Model GV-SP series airplanes, 
certificated in any category; serial numbers 5044-5063 inclusive.

Unsafe Condition

    (d) This AD results from a report that an airplane temporarily 
lost normal braking function during landing rollout on a pre-
delivery flight. We are issuing this AD to prevent loss of normal 
braking function, which could result in a runway overrun that could 
cause injury to flightcrew or passengers or damage to the airplane.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Inspection and Replacement If Necessary

    (f) Within 90 days after the effective date of this AD, inspect 
the anti-skid control unit (ACU) in the right electronics equipment 
rack to determine the serial number (S/N), in accordance with the 
Accomplishment Instructions of Gulfstream G500 Customer Bulletin 17, 
dated August 12, 2005 (for Model GV-SP (G500) series airplanes); or 
Gulfstream G550 Customer Bulletin 17, dated August 12, 2005 (for 
Model GV-SP (G550) series airplanes); as applicable. If the S/N of 
the ACU is in the affected range of S/N 355-400 inclusive: Replace 
the ACU with a new ACU having a S/N outside the affected range or 
with a serviceable ACU having a reidentified S/N, in accordance with 
the applicable customer bulletin.

    Note 1: The Accomplishment Instructions of the Gulfstream 
customer bulletins instruct operators to contact Gulfstream if 
technical assistance is required. However, any deviation from the 
instructions provided in the applicable customer bulletin must be 
approved as an alternative method of compliance under paragraph (h) 
of this AD.

No Reporting Requirement

    (g) Although the customer bulletins referenced in this AD 
specify to submit certain information to the manufacturer, this AD 
does not include that requirement.
