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.

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
E:\FR\FM\18MRR1.SGM
18MRR1
Federal Register / Vol. 81, No. 53 / Friday, March 18, 2016 / Rules and Regulations
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.
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 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
[[Page 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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive (AD):
2016-05-13 Pratt & Whitney Canada Corp. (Type Certificate previously
held by Pratt & Whitney Canada, Inc., Pratt & Whitney Aircraft of
Canada, Ltd., and United Aircraft of Canada, Ltd.): Amendment 39-
18431; Docket No. FAA-2015-3732; Directorate Identifier 2015-NE-25-
AD.
