PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: Air Tractor, Inc.: Docket No. FAA–2006– 24710; Directorate Identifier 2006–CE– 29–AD. Affected ADs (b) None. Applicability (c) This AD affects Models AT–802 and AT–802A airplanes, all serial numbers beginning with 802/802A–0001 through 802/ 802A–0219, that are certificated in any category. Unsafe Condition (d) This AD results from reports of an uncommanded change in engine power setting caused by separation of a hopper rinse tank shelf from the firewall. We are proposing this AD to detect and correct damage and/or cracks in the attach angles on the firewall mounted hopper rinse tank shelf, which could result in failure of the attach angles. This failure could lead to shelf movement under maneuver load and shifting of the engine power cables, which could result in an uncommanded engine power setting change. Compliance (e) To address this problem, you must do the following: Actions Compliance Procedures (1) Visually inspect the three attach angles on the firewall mounted hopper rinse tank shelf for damage and/or cracks. Initially inspect within the next 100 hours timein-service (TIS) after the effective date of this AD. Repetitively inspect thereafter at intervals not to exceed 100 hours TIS. Replacing all three attach angles with steel attach angles, part number (P/N) 60568–3 (or FAA-approved equivalent P/N), terminates the repetitive inspection requirement of this AD. Before further flight after the inspection in which damage and/or cracks are found. Replacing all three attach angles with steel attach angles, P/N 60568–3 (or FAA-approved equivalent P/N), terminates the repetitive inspection requirement of paragraph (e)(1) of this AD. As of the effective date of this AD ................... Follow Snow Engineering Co. Service Letter #248, dated August 31, 2005. As of the effective date of this AD ................... Not applicable. (2) If you find any damage and/or cracks on any of the three attach angles during any inspection required in paragraph (e)(1) of this AD, replace all three attach angles with steel attach angles, P/N 60568–3 (or FAA-approved equivalent P/N). (3) You may replace the aluminum attach angles on the firewall mounted hopper rinse tank shelf with steel attach angles, P/N 60568–3 (or FAA-approved equivalent P/N), at any time to terminate the repetitive inspections required in paragraph (e)(1) of this AD. (4) Do not install aluminum attach angles on the hopper rinse tank shelf attach angles. wwhite on PROD1PC61 with PROPOSALS (f) 14 CFR 21.303 allows for replacement parts through parts manufacturer approval (PMA). The phrase ‘‘or FAA-approved equivalent P/N’’ in this AD is intended to allow for the installation of parts approved through identicality to the design of the replacement parts. Equivalent replacement parts to correct the unsafe condition under PMA (other than identicality) may also be installed provided they meet current airworthiness standards, which include those actions cited in this AD.

Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A310–300 series airplanes. The DGAC advises of receiving a report that it was not possible to transfer fuel from auxiliary center tanks (ACTs) 1 and 2 during flight, and no electronic centralized aircraft monitor warnings were triggered. Investigation revealed a faulty static inverter and blown fuse, resulting in failure of certain fueling bus bars and subsequent failure of the automatic ACT fuel transfer. In addition, there are known problems with certain nonreturn valves (NRVs) used throughout the fuel system, which could result in intermittent failure of the NRV to close. If the NRV is open during flight, the fuel supply to the engines may be reduced during cross-feed operation to the extent that fuel starvation could occur and result in engine flameout. Relevant Service Information Airbus has issued Service Bulletin A310–28–2158, dated September 1, 2005. The service bulletin describes procedures for replacing the existing PO 00000 Frm 00005 Fmt 4702 Sfmt 4702 35401 NRV with a new, improved NRV. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive F–2005–197, dated December 7, 2005, to ensure the continued airworthiness of these airplanes in France. The Airbus service bulletin refers to Lucas Air Equipment Service Bulletin C23AE01–28–01, Revision 1, dated July 20, 1994, as an additional source of service information for replacing the NRV. FAA’s Determination and Requirements of the Proposed AD These airplane models are manufactured in France and are 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 DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’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 Airbus service information described previously. Costs of Compliance This proposed AD would affect about 11 airplanes of U.S. registry. The proposed replacement would take about 1 work hour per airplane, at an average labor rate of $80 per work hour. Required parts would cost about $368 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $4,928, or $448 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 E:\FR\FM\20JNP1.SGM 20JNP1 35402 Federal Register / Vol. 71, No. 118 / Tuesday, June 20, 2006 / Proposed Rules Applicability Issued in Renton, Washington, on June 14, 2006.

E6–9631 Filed 6–19–06; 8:45 am] 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. (c) This AD applies to Airbus Model A310– 304, –308, –324, and –325 airplanes, certificated in any category; equipped with auxiliary center tanks (ACTs); except those on which Airbus Modification 8928 has been done in production. Regulatory Findings Unsafe Condition 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. (d) This AD results from a report that it was not possible to transfer fuel from ACTs 1 and 2 during flight, and no electronic centralized aircraft monitor warnings were triggered. Investigation revealed a faulty static inverter and blown fuse, resulting in failure of certain fueling bus bars and subsequent failure of the automatic ACT fuel transfer. We are issuing this AD to prevent these failures, combined with failure of the non-return valve (NRV) to close. If the NRV is open during flight, the fuel supply to the engines may be reduced during cross-feed operation to the extent that fuel starvation could occur and result in engine flameout. DEPARTMENT OF DEFENSE Compliance SUMMARY: This proposed rule amends the exclusion of services and supplies provided as part of or under a research study, grant or research program to add coverage for routine patient care that would have been necessary in the absence of the study as well as care of complications that result from participation in the trial.

Airworthiness Directives; Airbus Model A310-300 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for certain Airbus Model A310-300 airplanes. This proposed AD would 
require replacing the existing non-return valve (NRV) of the auxiliary 
center tanks (ACTs) of the fuel system with a new, improved NRV. This 
proposed AD

[[Page 35401]]

results from a report that it was not possible to transfer fuel from 
ACTs 1 and 2 during flight, and no electronic centralized aircraft 
monitor warnings were triggered. Investigation revealed a faulty static 
inverter and blown fuse, resulting in failure of certain fueling bus 
bars and subsequent failure of the automatic ACT fuel transfer. We are 
proposing this AD to prevent these failures, combined with failure of 
the NRV to close. If the NRV is open during flight, the fuel supply to 
the engines may be reduced during cross-feed operation to the extent 
that fuel starvation could occur and result in engine flameout.

Discussion

    The Direction Generale de l'Aviation Civile (DGAC), which is the 
airworthiness authority for France, notified us that an unsafe 
condition may exist on certain Airbus Model A310-300 series airplanes. 
The DGAC advises of receiving a report that it was not possible to 
transfer fuel from auxiliary center tanks (ACTs) 1 and 2 during flight, 
and no electronic centralized aircraft monitor warnings were triggered. 
Investigation revealed a faulty static inverter and blown fuse, 
resulting in failure of certain fueling bus bars and subsequent failure 
of the automatic ACT fuel transfer. In addition, there are known 
problems with certain non-return valves (NRVs) used throughout the fuel 
system, which could result in intermittent failure of the NRV to close. 
If the NRV is open during flight, the fuel supply to the engines may be 
reduced during cross-feed operation to the extent that fuel starvation 
could occur and result in engine flameout.

Relevant Service Information

    Airbus has issued Service Bulletin A310-28-2158, dated September 1, 
2005. The service bulletin describes procedures for replacing the 
existing NRV with a new, improved NRV. Accomplishing the actions 
specified in the service information is intended to adequately address 
the unsafe condition. The DGAC mandated the service information and 
issued French airworthiness directive F-2005-197, dated December 7, 
2005, to ensure the continued airworthiness of these airplanes in 
France.
    The Airbus service bulletin refers to Lucas Air Equipment Service 
Bulletin C23AE01-28-01, Revision 1, dated July 20, 1994, as an 
additional source of service information for replacing the NRV.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are 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 DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC'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 Airbus service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 11 airplanes of U.S. registry. 
The proposed replacement would take about 1 work hour per airplane, at 
an average labor rate of $80 per work hour. Required parts would cost 
about $368 per airplane. Based on these figures, the estimated cost of 
the proposed AD for U.S. operators is $4,928, or $448 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

[[Page 35402]]

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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

Airbus: Docket No. FAA-2006-25079; Directorate Identifier 2006-NM-
065-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by July 20, 
2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A310-304, -308, -324, and -
325 airplanes, certificated in any category; equipped with auxiliary 
center tanks (ACTs); except those on which Airbus Modification 8928 
has been done in production.

Unsafe Condition

    (d) This AD results from a report that it was not possible to 
transfer fuel from ACTs 1 and 2 during flight, and no electronic 
centralized aircraft monitor warnings were triggered. Investigation 
revealed a faulty static inverter and blown fuse, resulting in 
failure of certain fueling bus bars and subsequent failure of the 
automatic ACT fuel transfer. We are issuing this AD to prevent these 
failures, combined with failure of the non-return valve (NRV) to 
close. If the NRV is open during flight, the fuel supply to the 
engines may be reduced during cross-feed operation to the extent 
that fuel starvation could occur and result in engine flameout.

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.

Replacement

    (f) Within 15,000 flight hours after the effective date of this 
AD: Replace the existing NRV with a new, improved NRV by doing all 
the actions in accordance with the Accomplishment Instructions of 
Airbus Service Bulletin A310-28-2158, dated September 1, 2005.


    Note 1: The Airbus service bulletin refers to Lucas Air 
Equipment Service Bulletin C23AE01-28-01, Revision 1, dated July 20, 
1994, as an additional source of service information for replacing 
the NRV.

Parts Installation

    (g) As of the effective date of this AD, no person may install, 
on any airplane, a NRV having part number C23AE0102, unless it has 
been modified according to paragraph (f) of this AD.
