Airworthiness Directives; Pratt & 

Whitney Canada Corp. Turboprop 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Pratt & Whitney Canada Corp. (P&WC) 

PT6A–60AG, –65AG, –67AF, and 

–67AG turboprop engines. This AD 

requires removing Woodward fuel 

control units (FCUs) and installing an 

FCU that is eligible for installation. This 

AD was prompted by incidents of 

corrosion and perforation of the two-ply 

Cu-Be bellows in Woodward FCUs. We 

are issuing this AD to prevent failure of 

the Woodward FCU and engine, inflight shutdown, and loss of control of 

the airplane. 

DATES: This AD becomes effective April 

22, 2016. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of April 22, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on November 10, 2015 (80 FR 

69623). The NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

There have been in-service incidents 

involving corrosion and perforation of the 

two-ply Cu-Be bellows in Woodward Fuel 

Control Units (FCU) fitted to PT6A–60, –65 

and –67 series engines. In certain instances, 

associated bellows leakage has resulted in 

loss of engine power, in-flight shutdowns 

(IFSD) and even accidents. Engines installed 


asabaliauskas on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 81, No. 53 / Friday, March 18, 2016 / Rules and Regulations 14701 

on the aeroplanes that are used for crop 

dusting, due to the operational environment, 

are more susceptible to corrosion damage to 

the subject bellows. 

Loss of engine power or shut down in 

flight by itself usually is not considered a 

catastrophic event. However, on an aeroplane 

with single engine installation, an engine 

power loss or IFSD at a critical phase of flight 

could adversely affect the safe operation of 

the aeroplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 69623, November 10, 2015). 

We updated the revision number and 

date of P&WC Service Bulletin No. 

PT6A–72–14389. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of 

this AD. 

Related Service Information Under 

1 CFR Part 51 

P&WC has issued Service Bulletin 

(S.B.) No. PT6A–72–14389, Revision 

No. 4, dated February 3, 2016 (P&WC 

S.B. No. 14389R4) and S.B. No. PT6A– 

72–13473, Revision No. 1, dated May 

26, 2015 (P&WC S.B. No. 13473R1). The 

service information describes 

procedures for replacing Woodward 

FCUs. This service information is 

reasonably available because the 

interested parties have access to it 

through their normal course of business 

or by the means identified in the 

ADDRESSES section of this final rule. 

Costs of Compliance 

We estimate that this AD affects 341 

engines installed on airplanes of U.S. 

registry. We also estimate that it will 

take about 1.5 hours per engine to 

comply with this AD. The average labor 

rate is $85 per hour. Required parts cost 

about $1,000 per engine. Based on these 

figures, we estimate the cost of this AD 

on U.S. operators to be $384,478. 

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 determined that this AD will not 

have federalism implications under 

Executive Order 13132. This AD will 

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 this AD: 

(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.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Quest Aircraft Design, 

LLC Model KODIAK 100 airplanes. The 

NPRM published in the Federal 

Register on November 5, 2015 (80 FR 

68477). The NPRM was prompted by a 

report of limited control yoke movement 

of the elevator control system due to 

cushion edging jammed in the elevator 

control anti-rotation guide slot. The 

NPRM proposed to require repetitively 

inspecting the elevator control system 

cushion edging for proper condition; 

replacing the cushion edging; and at a 

specified time terminating the repetitive 

inspections by installing wear pads on 

the elevator bearing assemblies. We are 

issuing this AD to correct the unsafe 

condition on these products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the NPRM (80 FR 68477, 

November 5, 2015) and the FAA’s 

response to each comment. 

Request To Include Revised Service 

Bulletin 

Quest Aircraft Design revised one of 

the related service bulletins and 

requested that Quest Aircraft Company 

KODIAK 100 Mandatory Service 

Bulletin SB14–07, Revision 01, dated 

November 23, 2015, be incorporated 

into the final rule AD action. 

We agree. We revised this AD as 

requested. 

Request To Reference Only the Field 

Service Instructions 

Quest Aircraft Design stated that the 

instructions for doing the actions 

required in the AD are actually
