Avocados Grown in South Florida; 

Continuance Referendum 

AGENCY: Agricultural Marketing Service, 

USDA. 

ACTION: Referendum order. 

SUMMARY: This document directs that a 

referendum be conducted among 

eligible producers of avocados grown in 

South Florida to determine whether 

they favor continuance of the marketing 

order regulating the handling of 

avocados grown in the production area. 

DATES: The referendum will be 

conducted from January 12 through 

January 27, 2015. To vote in this 

referendum, producers must have 

produced Florida avocados within the 

designated production area during the 

period April 1, 2013, through March 31, 

2014. 

ADDRESSES: Copies of the marketing 

order may be obtained from the 

referendum agents at 1124 First Street 

South, Winter Haven, FL 33880, or the

SUPPLEMENTARY INFORMATION: Pursuant 

to Marketing Order No. 915, as amended 

(7 CFR part 915), hereinafter referred to 

as the ‘‘order,’’ and the applicable 

provisions of the Agricultural Marketing 

Agreement Act of 1937, as amended (7 

U.S.C. 601–674), hereinafter referred to 

as the ‘‘Act,’’ it is hereby directed that 

a referendum be conducted to ascertain 

whether continuance of the order is 

favored by producers. The referendum 

shall be conducted from January 12 

through January 27, 2015, among 

Florida avocados growers in the 

production area. Only Florida avocado 

producers that were engaged in the 

production of Florida avocado, during 

the period of April 1, 2013, through 

March 31, 2014, may participate in the 

continuance referendum. 

USDA has determined that 

continuance referenda are an effective 

means for determining whether 

producers favor the continuation of 

marketing order programs. USDA would 

consider termination of the order if less 

than two-thirds of the producers voting 

in the referendum and less than twothirds of the volume of Florida avocados 

represented in the referendum favor 

continuance. In evaluating the merits of 

continuance versus termination, USDA 

will not exclusively consider the results 

of the continuance referendum. USDA 

will also consider all other relevant 

information concerning the operation of 

the order and the relative benefits and 

disadvantages to producers, handlers, 

and consumers in order to determine 

whether continued operation of the 

order would tend to effectuate the 

declared policy of the Act. 

In accordance with the Paperwork 

Reduction Act of 1995 (44 U.S.C. 3501– 

3520), the ballot materials to be used in 

the referendum have been submitted to 

and approved by the Office of 

Management and Budget (OMB) and 

have been assigned OMB No. 0581– 

0189, Generic Fruit Crops. It has been 

estimated that it will take an average of 

20 minutes for each of the 

approximately 300 producers of Florida 

avocados to cast a ballot. Participation 

is voluntary. Ballots postmarked after 

January 27, 2015, will not be included 

in the vote tabulation. 

Doris Jamieson and Christian D. 

Nissen of the Southeast Marketing Field 

Office, Fruit and Vegetable Program, 

AMS, USDA, are hereby designated as 

the referendum agents of the Secretary 

of Agriculture to conduct this 

referendum. The procedure applicable 

to the referendum shall be the 

‘‘Procedure for the Conduct of 

Referenda in Connection With 

Marketing Orders for Fruits, Vegetables, 

and Nuts Pursuant to the Agricultural 

Marketing Agreement Act of 1937, as 

Amended’’ (7 CFR 900.400–900.407). 

Ballots will be mailed to all producers 

of record and may also be obtained from 

the referendum agents, or from their 

appointees.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to revise 

airworthiness directive (AD) 2014–17– 

08 that applies to all Pratt & Whitney 

Canada Corp. (P&WC) PT6A–114 and 

PT6A–114A turboprop engines. AD 

2014–17–08 requires initial and 

repetitive borescope inspections (BSIs) 

of compressor turbine (CT) blades, and 

the removal from service of blades that 

fail inspection. Since we issued AD 

2014–17–08, P&WC developed an 

additional single crystal CT blade that 

corrects the unsafe condition. This 

proposed AD would retain all the 

requirements of AD 2014–17–08, add an 

additional single crystal CT blade that 

corrects the unsafe condition, reduce 

the affected population, and correct the 

Credit for Previous Action paragraph.

substantive verbal contact we receive 

about this NPRM. 

Discussion 

On August 18, 2014, we issued AD 

2014–17–08, Amendment 39–17961 (79 

FR 52172, September 3, 2014), (‘‘AD 

2014–17–08’’), for all P&WC PT6A–114 

and PT6A–114A turboprop engines. AD 

2014–17–08 requires initial and 

repetitive BSIs of CT blades, and the 

removal from service of blades that fail 

inspection. AD 2014–17–08 resulted 

from several incidents of CT blade 

failure, causing power loss, and engine 

failure. We issued AD 2014–17–08 to 

prevent failure of CT blades, which 

could result in damage to the engine 

and damage to the airplane. 

Actions Since AD 2014–17–08 Was 

Issued 

Since we issued AD 2014–17–08 (79 

FR 52172, September 3, 2014), P&WC 

developed a new single crystal CT 

blade, P/N 3079351–01, to correct the 

unsafe condition. The addition of this 

new P/N reduces the affected 

population. Finally, we determined that 

in AD 2014–07–08, we gave credit for 

action that is inapplicable to the unsafe 

condition. Specifically, in the Credit for 

Previous Action paragraph, the AD 

allows credit for a previously performed 

metallurgical examination of ‘‘single 

crystal CT blades’’. Metallurgical 

examination of single crystal CT blades 

is inapplicable to the non-single crystal 

CT blades referenced in Compliance 

paragraph (e)(1)(iii)(B) of this NPRM. 

Relevant Service Information 

We reviewed P&WC Service Bulletin 

(SB) No. PT6A–72–1669, Revision 9, 

dated June 28, 2013. The service 

information describes procedures for 

correcting the unsafe condition. 

FAA’s Determination 

We are proposing this NPRM 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 NPRM would require initial and 

repetitive BSIs of CT blades, and the 

removal from service of blades that fail 

inspection. This NPRM would also 

require as a mandatory terminating 

action, replacement of non-single crystal 

CT blades with single crystal CT blades 

at the next shop visit. This NPRM also 

corrects the reference to single crystal 

CT blades in the Credit for Previous 

Action paragraph. This NPRM also 

reduces the affected population by 

introducing a new single crystal CT 

blade P/N that addresses the unsafe 

condition. 

Costs of Compliance 

We estimate that this proposed AD 

affects 300 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 4 

hours per engine to perform the 

required inspection and 8 hours to 

replace the blades. The average labor 

rate is $85 per hour. Required parts cost 

about $59,334 per engine. Based on 

these figures, we estimate the cost of 

this proposed AD on U.S. operators to 

be $18,106,200. 

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

Federal Register / Vol. 79, No. 230 / Monday, December 1, 2014 / Proposed Rules 71033 

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.
