AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Proposed rule; withdrawal. 

SUMMARY: The FAA is withdrawing a 

notice of proposed rulemaking (NPRM). 

The NPRM proposed a new 

airworthiness directive (AD) that had 

applied to AlliedSignal oil scavenge 

pumps, part numbers (P/Ns) 101633–01 

and –02 and Rajay Inc. oil scavenge 

pumps, P/Ns 1025–1 and –2 installed on 

Continental Motors, Inc. (CMI) IO–470 

and TSIO–520 reciprocating engines 

and on Lycoming Engines, Inc., 

(Lycoming) IO–360, IO–540, and O–360 

reciprocating engines. We have found 

no service difficulties with these model 

oil scavenge pumps when installed on 

the affected engines. Accordingly, we 

withdraw the proposed rule. 

DATES: As of June 19, 2015, the 

proposed rule published February 20, 

1997 at 62 FR 7730 is withdrawn.

6590; email: richard.mccauley@faa.gov. 

SUPPLEMENTARY INFORMATION: The FAA 

proposed to amend 14 CFR part 39 with 

a proposed AD (62 FR 7730, February 

20, 1997). The proposed AD had applied 

to AlliedSignal oil scavenge pumps, 

P/Ns 101633–01 and –02 and Rajay Inc. 

oil scavenge pumps, P/Ns 1025–1 and 

–2 installed on CMI IO–470 and TSIO– 

520 reciprocating engines and on 

Lycoming IO–360, IO–540, and O–360 

reciprocating engines. The NPRM 

proposed to require initial and 

repetitive inspections of the oil 

scavenge pump for the security of the 

snap ring installation, snap ring and 

washer wear, and shaft groove wear, and 

their replacement, if necessary, with 

serviceable parts. The proposed action 

was prompted by reports of severe wear 

on the end plate of the oil scavenge 

pump. The proposed actions were 

intended to prevent oil scavenge pump 

snap ring failure causing severe wear on 

the pump end plate, which could result 

in loss of engine oil and subsequent 

engine shutdown. 

Since we issued the NPRM (62 FR 

7730, February 20, 1997), additional 

information became available after the 

public comment period closed on April 

21, 1997. 

Upon further consideration, we 

hereby withdraw the proposed rule for 

the following reason: 

• We reviewed service difficulty 

reports, AD databases, and airplane 

manufacturer’s data and found no 

unsafe condition in the last 19 years of 

service history associated with these oil 

scavenge pumps installed on the 

affected engines. 

Withdrawal of the NPRM (62 FR 7730, 

February 20, 1997) constitutes only such 

action, and does not preclude the 

agency from issuing another notice in 

the future, nor does it commit the 

agency to any course of action in the 

future. 

Since this action only withdraws a 

notice of proposed rulemaking, it is 

neither a proposed nor a final rule. 

Therefore, Executive Order 12866, the 

Regulatory Flexibility Act, or DOT 

Regulatory Policies and Procedures (44 

FR 11034, February 26, 1979) do not 

cover this withdrawal.

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Pratt & Whitney Canada Corp. (P&WC) 

PT6B–37A turboshaft engines. This 

proposed AD was prompted by reports 

of incorrect engine torque for PT6B–37A 

engines. This proposed AD would 

require initial and repetitive inspections 

until replacement of the No. 10 bearing, 

and eventual replacement of the No. 9 

bearing, both located in the engine 

reduction gearbox (RGB) assembly. We 

are proposing this AD to prevent axial 

migration of the No. 10 bearing in the 

engine RGB assembly, which could lead 

to engine overtorque, failure of the 

engine, in-flight shutdown, and loss of 

the rotorcraft. 

DATES: We must receive comments on 

this proposed AD by August 18, 2015. 

ADDRESSES: You may send comments by 

any of the following methods:

Discussion 

The Transport Canada Civil Aviation, 

which is the aviation authority for 

Canada, has issued Canada AD CF– 

2015–01, dated January 20, 2015 

(referred to hereinafter as ‘‘the MCAI’’), 

to correct an unsafe condition for the 

specified products. The MCAI states: 

Five incidences of incorrect engine torque 

indication have been reported for PT6B–37A 

engine installations on AW119MKII 

helicopters. A lower than actual engine 

torque indication due to a faulty indication 

system, particularly on a helicopter being 

operated at max allowable torque (90 to 

110%) range, may result in undetected overtorque condition. 

Repeated over-torque conditions that are 

undetected and consequently are not 

corrected in accordance with conditional 

inspection requirements of original 

equipment manufacturer (OEM) Instructions 

for Continued Airworthiness (ICAs), may 

have a negative impact on the operational 

safety of the aircraft. Investigation by P&WC 

has determined the root cause of the subject 

torque indication anomaly to be the axial 

migration of part number (P/N) 3310433–03 

bearings at the engine torque sensing gear 

location. 

The axial migration of the No. 10 

bearing is caused by non-optimal 

bearing internal clearance. This 

migration may cause an erroneous 

torque reading, possibly leading to 

engine overtorque and engine failure. 

We are also requiring replacement of the 

No. 9 bearing since it may also migrate, 

has the same part number as a No. 10 

bearing, and could be installed in the 

same location as a No. 10 bearing. 

You may obtain further information 

by examining the MCAI in the AD 

docket on the Internet at http://

www.regulations.gov by searching for 

and locating Docket No. FAA–2015– 

0486. 

Related Service Information Under 1 

CFR Part 51 

P&WC has issued Service Bulletin 

(SB) No. PT6B–72–39095, Revision No. 

3, dated December 29, 2014. The service 

information describes procedures for 

inspecting affected bearings. 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 NPRM. 

Other Related Service Information 

P&WC has also issued SB No. PT6B– 

72–39092, Revision No. 4, dated 

December 29, 2014. The service 

information describes procedures for 

removing affected bearings. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of Canada, and is 

approved for operation in the United 

States. Pursuant to our bilateral 

agreement with Canada, they have 

notified us of the unsafe condition 

described in the MCAI and service 

information referenced above. We are 

proposing this AD because we evaluated 

all information provided by Transport 

Canada Civil Aviation and determined 

the unsafe condition exists and is likely 

to exist or develop on other products of 

the same type design. This proposed AD 

would require initial and repetitive 

inspections until replacement of the No. 

10 bearing, as well as eventual 

replacement of the No. 9 bearing, in the 

engine RGB assembly. 

Costs of Compliance 

We estimate that this proposed AD 

affects 83 engines installed on rotorcraft 

of U.S. registry. We estimate that it 

would take about 3 hours per engine to 

perform the initial and repetitive 

inspections to comply with this 

proposed AD. We also estimate that it 

would take about 1 hour per engine to 

replace the affected bearings. The 

average labor rate is $85 per hour. 

Required parts cost about $49,800 per 

engine. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $4,161,620. 

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 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.

35262 Federal Register / Vol. 80, No. 118 / Friday, June 19, 2015 / Proposed Rules 

For the reasons discussed above, I 

certify this 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.

done. 

(1) Initial Inspection 

(i) Within 50 flight hours (FHs) time in 

service after the effective date of this AD, 

inspect the No. 10 bearing, part number 

(P/N) 3310433–03, in the RGB assembly for 

axial movement. Use paragraphs 3.A. to 3.C. 

in the Accomplishment Instructions in 

P&WC SB No. PT6B–72–39095, Revision No. 

3, dated December 29, 2014, to do the 

inspection. If the bearing fails the inspection, 

replace the No. 9 and No. 10 bearings before 

further flight. 

(2) Repetitive Inspection 

(i) For engines with 500 FHs or less total 

time since new (TSN), repeat the inspection 

required by paragraph (e)(1) of this AD every 

100 FHs time since last inspection (TSLI) 

until 500 hours total TSN, and, thereafter, 

every 200 FHs TSLI until removal. 

(ii) For engines with more than 500 FHs 

total TSN perform the inspection required by 

paragraph (e)(1) to this AD within 200 FHs 

TSLI, and, thereafter, every 200 FHs TSLI 

until removal.

(iii) Replacement of the No. 9 and No. 10 

bearing, P/N 3310433–03, with the No. 9 and 

No. 10 bearing, P/N 3310233–03 or P/N 

3310533–03, is terminating action for this 

AD. 

(f) Reporting Requirements 

You do not have to contact your Local 

Field Service Representative as discussed in 

paragraph 3.C.(3) of P&WC SB No. PT6B–72– 

39095, Revision No. 3, dated December 29, 

2014.
