SUPPLEMENTARY INFORMATION: Pursuant to the Commodity Promotion, Research and Information Act of 1996 (7 U.S.C. 7411–7425) (Act), it is hereby directed that a referendum be conducted to ascertain whether continuance of the pmangrum on DSK3VPTVN1PROD with PROPOSALS-1 SUMMARY: VerDate Mar<15>2010 14:04 Jan 16, 2014 Jkt 232001 Order is favored by producers of peanuts covered under the program. The Order is authorized under the Act. The representative period for establishing voter eligibility for the referendum shall be the period from January 1 through December 31, 2013. Persons who are currently producers of peanuts, and who produced peanuts and paid assessments during the representative period are eligible to vote. Persons who received an exemption from assessments for the entire representative period are ineligible to vote. The referendum shall be conducted by mail from April 7 through April 18, 2014. Section 518 of the Act authorizes continuance referenda. Under section 1216.82 of the Order, the U.S. Department of Agriculture (Department) must conduct a referendum every five years or when 10 percent or more of the eligible peanut producers petition the Secretary of Agriculture to hold a referendum to determine if persons subject to assessment favor continuance of the Order. The Department would continue the Order if continuance is approved by a simple majority of the producers voting in the referendum. In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. chapter 35), the referendum ballot has been approved by the Office of Management and Budget (OMB) and assigned OMB No. 0581–0093. It has been estimated that there are approximately 9,208 producers who will be eligible to vote in the referendum. It will take an average of 15 minutes for each voter to read the voting instructions and complete the referendum ballot. Jeanette Palmer and Sonia Jimenez, PED, FVP, AMS, USDA, Stop 0244, Room 1406–S, 1400 Independence Avenue SW., Washington, DC 20250– 0244, are designated as the referendum agents to conduct this referendum.

Discussion On December 20, 1990, we issued AD 90–26–01 (55 FR 49611, November 30, 1990), for GE CF6–80C2 series turbofan engines. That AD requires replacing fuel manifold, part numbers (P/Ns) 1303M31G04 and 1303M32G04, within 30 calendar days after the effective date of the AD. That AD resulted from a report of an engine fire. On November 15, 1991, we issued AD 91–20–02 (56 FR 55231, October 25, 1991), for the same engines. That AD requires replacing fuel manifold, P/Ns 1303M31G06, 1303M32G06, 1303M31G07, 1303M32G07, 1303M31G08, and 1303M32G08, at the next engine removal, but no later than June 30, 1993. That AD also resulted from a report of an engine fire. On March 31, 2009, we issued AD 2009–05–02 (74 FR 8161, February 24, 2009), for GE CF6–80C2 and CF6–80E1 series turbofan engines with fuel manifolds, P/Ns 1303M31G12 and 1303M32G12, installed in drainless fuel manifold assemblies. That AD requires removing the loop clamps that hold the fuel manifold to the compressor rear frame damper brackets, inspecting the fuel manifold for wear at each clamp location, and replacing the clamps with new zero-time parts. That AD also requires revising the Airworthiness Limitations Section to require repetitive fuel manifold inspection and loop clamp replacement. That AD resulted from reports of fuel leaks during engine operation. We issued these ADs to prevent failure of the fuel manifold, which could lead to uncontrolled engine fire, engine damage, and damage to the airplane. We are superseding these ADs to eliminate potentially confusing and contradictory requirements in these ADs. This proposed AD expands the inspection mandated by AD 2009–05–02 and it expands the list of banned fuel manifolds mandated by AD 90–26–01 and AD 91–20–02. PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 Actions Since Previous ADs Were Issued Since we issued AD 90–26–01 (55 FR 49611, November 30, 1990); AD 91–20– 02 (56 FR 55231, October 25, 1991); and AD 2009–05–02 (74 FR 8161, February 24, 2009); we received a report of an undercowl fire caused by a fuel manifold high-pressure fuel leak in engine model CF6–80C2, and several additional reports of fuel leaks; four in the CF6–80C2 and one in the CF6–80E1 model engine. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. Proposed AD Requirements This proposed AD would retain the requirements of AD 90–26–01 (55 FR 49611, November 30, 1990); and AD 91– 20–02 (56 FR 55231, October 25, 1991); to remove certain fuel manifold P/Ns, and the requirements of AD 2009–05–02 (74 FR 8161, February 24, 2009); to inspect certain fuel manifold P/Ns and replace certain consumable components. This proposed AD would add a requirement to inspect an additional fuel manifold configuration and replacement of certain loop clamps. This proposed AD would also require repetitive inspection and replacement of tube (block) clamp, and inspection of the fuel manifold for wear at each tube (block) clamp location. This proposed AD would also require removing certain drainless fuel manifold assembly P/Ns from service. Costs of Compliance We estimate that this proposed AD would affect 1,126 engines installed on airplanes of U.S. registry. We also estimate that required parts cost about $34,894 per engine. We also estimate that is would take about 6 hours to accomplish the actions required by this AD. The average labor rate is $85 per hour. Based on these figures, we estimate the total cost of the proposed AD to U.S. operators to be $39,864,904. 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, E:\FR\FM\17JAP1.SGM 17JAP1 Federal Register / Vol. 79, No. 12 / Friday, January 17, 2014 / Proposed Rules 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 proposed 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), (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction, and (4) 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, 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.

Airworthiness Directives; General Electric Company Turbofan 
Engines

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directives (ADs) 90-26-
01, 91-20-02, and 2009-05-02, which apply to all General Electric 
Company (GE) CF6-80C2 and CF6-80E1 series turbofan engines. Since we 
issued ADs 90-26-01, 91-20-02, and 2009-05-02, we received a report of 
an undercowl fire caused by a manifold high-pressure fuel leak, and 
several additional reports of fuel leaks. This proposed AD would 
require additional repetitive inspections, replacement of tube (block) 
clamp, and inspection of fuel manifolds for wear at each tube (block) 
clamp location. We are proposing this AD to

[[Page 3140]]

prevent failure of the fuel manifold, which could lead to uncontrolled 
engine fire, engine damage, and damage to the airplane.

Discussion

    On December 20, 1990, we issued AD 90-26-01 (55 FR 49611, November 
30, 1990), for GE CF6-80C2 series turbofan engines. That AD requires 
replacing fuel manifold, part numbers (P/Ns) 1303M31G04 and 1303M32G04, 
within 30 calendar days after the effective date of the AD. That AD 
resulted from a report of an engine fire.
    On November 15, 1991, we issued AD 91-20-02 (56 FR 55231, October 
25, 1991), for the same engines. That AD requires replacing fuel 
manifold, P/Ns 1303M31G06, 1303M32G06, 1303M31G07, 1303M32G07, 
1303M31G08, and 1303M32G08, at the next engine removal, but no later 
than June 30, 1993. That AD also resulted from a report of an engine 
fire.
    On March 31, 2009, we issued AD 2009-05-02 (74 FR 8161, February 
24, 2009), for GE CF6-80C2 and CF6-80E1 series turbofan engines with 
fuel manifolds, P/Ns 1303M31G12 and 1303M32G12, installed in drainless 
fuel manifold assemblies. That AD requires removing the loop clamps 
that hold the fuel manifold to the compressor rear frame damper 
brackets, inspecting the fuel manifold for wear at each clamp location, 
and replacing the clamps with new zero-time parts. That AD also 
requires revising the Airworthiness Limitations Section to require 
repetitive fuel manifold inspection and loop clamp replacement. That AD 
resulted from reports of fuel leaks during engine operation.
    We issued these ADs to prevent failure of the fuel manifold, which 
could lead to uncontrolled engine fire, engine damage, and damage to 
the airplane. We are superseding these ADs to eliminate potentially 
confusing and contradictory requirements in these ADs. This proposed AD 
expands the inspection mandated by AD 2009-05-02 and it expands the 
list of banned fuel manifolds mandated by AD 90-26-01 and AD 91-20-02.

Actions Since Previous ADs Were Issued

    Since we issued AD 90-26-01 (55 FR 49611, November 30, 1990); AD 
91-20-02 (56 FR 55231, October 25, 1991); and AD 2009-05-02 (74 FR 
8161, February 24, 2009); we received a report of an undercowl fire 
caused by a fuel manifold high-pressure fuel leak in engine model CF6-
80C2, and several additional reports of fuel leaks; four in the CF6-
80C2 and one in the CF6-80E1 model engine.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This proposed AD would retain the requirements of AD 90-26-01 (55 
FR 49611, November 30, 1990); and AD 91-20-02 (56 FR 55231, October 25, 
1991); to remove certain fuel manifold P/Ns, and the requirements of AD 
2009-05-02 (74 FR 8161, February 24, 2009); to inspect certain fuel 
manifold P/Ns and replace certain consumable components. This proposed 
AD would add a requirement to inspect an additional fuel manifold 
configuration and replacement of certain loop clamps. This proposed AD 
would also require repetitive inspection and replacement of tube 
(block) clamp, and inspection of the fuel manifold for wear at each 
tube (block) clamp location. This proposed AD would also require 
removing certain drainless fuel manifold assembly P/Ns from service.

Costs of Compliance

    We estimate that this proposed AD would affect 1,126 engines 
installed on airplanes of U.S. registry. We also estimate that required 
parts cost about $34,894 per engine. We also estimate that is would 
take about 6 hours to accomplish the actions required by this AD. The 
average labor rate is $85 per hour. Based on these figures, we estimate 
the total cost of the proposed AD to U.S. operators to be $39,864,904.

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,

[[Page 3141]]

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 proposed 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),
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction, and
    (4) 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.
