SUPPLEMENTARY INFORMATION: 

Discussion 

We issued AD 2017–15–02, 

Amendment 39–18962 (82 FR 33439, 

July 20, 2017), (‘‘AD 2017–15–02’’). AD 

2017–15–02 applied to Bell Model 212 

and 412 helicopters with an engine oil 

or fuel check valve part number (P/N) 

209–062–520–001 or P/N 209–062–607– 

001 that was manufactured by Circor 

Aerospace, marked ‘‘Circle Seal’’ and 

marked with a manufacturing date code 

of ‘‘10/11’’ (October 2011) through ‘‘03/ 

15’’ (March 2015) installed. AD 2017– 

15–02 resulted from a report that certain 

part numbered 209–062–520–001 check 

valves manufactured by Circor 

Aerospace as replacement parts have 

been found cracked or leaking on 

several Bell Model 427 and Model 429 

helicopters. These check valves may be 

installed as engine oil check valves on 

Bell Model 212 helicopters. Similar 

check valves, part number 209–062– 

607–001, may be installed as fuel check 

valves on Bell Model 212 or 412 

helicopters. These check valves may 

have a condition induced during 

assembly that can cause the valve body 

to crack, resulting in oil or fuel leakage. 

This condition could result in loss of 

lubrication or fuel to the engine, failure 

of the engine or a fire, and subsequent 

loss of control of the helicopter. To 

address this condition, AD 2017–15–02 

required replacing the engine oil and 

fuel check valves and prohibited 

installing an affected check valve on any 

helicopter. 

Actions Since AD 2017–15–02 Was 

Issued 

Since we issued AD 2017–15–02, we 

discovered an error in that Bell Model 

412CF and 412EP helicopters should 

have been included in the applicability 

of the AD. Additionally, Bell revised its 

service information to exclude check 

valves identified with ‘‘TQL’’ regardless 

of manufacture date. Check valves 

marked ‘‘TQL’’ were manufactured 

using a different process and are not 

affected by the unsafe condition. 

Therefore, we are superseding AD 2017– 

15–02 to add Bell Model 412CF and 

412EP helicopters to the applicability 

and to exclude check valves marked 

‘‘TQL.’’ 

Related Service Information 

We reviewed Bell Alert Service 

Bulletin (ASB) 212–15–153, Revision A, 

dated October 6, 2017 (212–15–153), 

and Bell ASB 212–15–155, Revision A, 

dated October 6, 2017 (212–15–155), for 

Model 212 helicopters; Bell ASB 412– 

15–165, Revision A, dated October 6, 

2017 (412–15–165), and Bell ASB 412– 

15–168, Revision A, dated October 6, 

2017 (ASB 412–15–168), for Model 412 

and 412 EP helicopters; and Bell ASB 

412CF–15–57, Revision A, dated 

October 6, 2017 (412CF–15–57), and 

Bell ASB 412CF–15–59, Revision A, 

dated October 6, 2017 (412CF–15–59), 

for Model 412CF helicopters. ASB 212– 

15–153, ASB 412–15–165, and ASB 

412–CF–15–57 contain procedures for 

inspecting and replacing engine oil 

check valve P/N 209–062–520–001. ASB

sradovich on DSK3GMQ082PROD with RULES
42206 Federal Register / Vol. 83, No. 162 / Tuesday, August 21, 2018 / Rules and Regulations 

412CF–15–59 contain procedures for 

inspecting and replacing fuel check 

valve P/N 209–062–607–001. Revision 

A of the service information clarifies 

that check valves identified with ‘‘TQL’’ 

are not affected by the ASB procedures. 

FAA’s Determination 

We are issuing 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 these same 

type designs. 

AD Requirements 

This AD requires, within 25 hours 

time-in-service (TIS), replacing the 

engine oil and fuel check valves. This 

AD also prohibits installing on any 

helicopter a check valve P/N 209–062– 

520–001 or P/N 209–062–607–001 that 

was manufactured by Circor Aerospace, 

marked ‘‘Circle Seal’’ and marked with 

a manufacturing date code of ‘‘10/11’’ 

(October 2011) through ‘‘03/15’’ (March 

2015), except if ‘‘TQL’’ is marked next 

to the manufacturing date code. 

FAA’s Justification and Determination 

of the Effective Date 

An unsafe condition exists that 

requires the immediate adoption of this 

AD without providing an opportunity 

for public comments prior to adoption. 

The FAA has found that the risk to the 

flying public justifies waiving notice 

and comment prior to adoption of this 

rule because the actions required by this 

AD must be accomplished within 25 

hours TIS, a very short interval for 

helicopters used in firefighting and 

logging operations. Therefore, we find 

good cause that notice and opportunity 

for prior public comment are 

impracticable. In addition, for the 

reason stated above, we find that good 

cause exists for making this amendment 

effective in less than 30 days. 

Comments Invited 

This AD is a final rule that involves 

requirements affecting flight safety, and 

we did not provide you with notice and 

an opportunity to provide your 

comments before it becomes effective. 

However, we invite you to send any 

written data, views, or arguments about 

this final rule. Send your comments to 

an address listed under the ADDRESSES

section. Include the docket number 

FAA–2018–0738 and product identifier 

2017–SW–132–AD at the beginning of 

your comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this final rule. We will 

consider all comments received by the 

closing date and may amend this final 

rule because of those comments. 

We will post all comments we 

receive, without change, to http://

www.regulations.gov, including any 

personal information you provide. We 

will also post a report summarizing each 

substantive verbal contact we receive 

about this final rule. 

Costs of Compliance 

We estimate that this AD affects 161 

(59 Model 212 and 102 Model 412) 

helicopters of U.S. Registry. 

We estimate that operators may incur 

the following costs in order to comply 

with this AD. At an average labor rate 

of $85, replacing each check valve 

(engine oil or fuel) will require about 1 

work-hour, and required parts will cost 

$85. For the Model 212, we estimate a 

total cost of $340 per helicopter and 

$20,060 for the U.S. fleet. For the Model 

412, we estimate a total cost of $170 per 

helicopter and $17,340 for the U.S. fleet. 

According to Bell’s service 

information some of the costs of this AD 

may be covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage by Bell. Accordingly, we have 

included all costs in our cost estimate. 

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 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979), 

(3) Will not affect intrastate aviation 

in Alaska, 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 to supersede AD 2016–03–03, 

Amendment 39–18390 (81 FR 12585, 

March 10, 2016) (‘‘AD 2016–03–03’’). 

AD 2016–03–03 applied to all RR Viper 

Mk. 521, Viper Mk. 522, and Viper Mk. 

601–22 turbojet engines. The NPRM 

published in the Federal Register on 

December 15, 2017 (82 FR 59560). The 

NPRM was prompted by RR 

determining that additional compressor 

rotating shrouds and the compressor 

main shaft, installed on the affected 

Viper turbojet engines, require a 

reduction in their cyclic life limits. Also 

since we issued AD 2016–03–03, the 

European Aviation Safety Agency 

(EASA) has issued AD 2017–0148, dated 

August 15, 2017, which requires 

reducing the cyclic life limits of the 

affected parts. The NPRM proposed to 

add additional engine parts to the 

applicability. We are issuing this AD to 

address the unsafe condition on these 

products. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting this AD 

as proposed except for minor editorial 

changes.
