Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Pratt & Whitney Canada Corp. (P&WC) 

PW210A and PW210S model turboshaft 

engines. This proposed AD was 

prompted by a report from the 

manufacturer that the Automated 

Damage Tracking System (ADTS) may 

under-count the number of cycles 

accrued by the impeller and the highpressure compressor (HPC) rotor. The 

impeller and HPC rotor are both lifelimited components and exceeding their 

published life limits could result in the 

failure of these components. This 

proposed AD would require the use of 

the manual low-cycle fatigue (LCF) 

counting method in place of the ADTS 

counting method to determine the 

number of cycles accrued by the 

impeller and HPC rotor. The FAA is 

proposing this AD to address the unsafe 

condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by April 12, 2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

Transport Canada Civil Aviation 

(Transport Canada), which is the 

aviation authority for Canada, has 

issued Transport Canada AD CF–2020– 

13, dated April 28, 2020 (referred to 

after this as ‘‘the MCAI’’), to address the 

unsafe condition on these products. The 

MCAI states: 

The engine manufacturer has discovered 

that the Automated Damage Tracking System 

(ADTS) may under-count the number of 

cycles accrued by the impeller and the High 

Pressure (HP) compressor rotor. The impeller 

and HP compressor rotor are both life limited 

components and exceeding their published 

life limits could result in the failure of these 

components. 

Failure of the impeller or HP compressor 

rotor could result in the uncontained release 

of the impeller or the HP compressor rotor, 

and subsequently could result in damage to 

the engine, damage to the helicopter, and loss 

of control of the helicopter. 

This [Transport Canada] AD mandates the 

use of the Manual Low Cycle Fatigue (LCF) 

Counting method to ensure that the impeller 

and HP compressor rotor do not exceed their 

published life limits.

FAA’s Determination 

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, Transport 

Canada has notified the FAA of the 

unsafe condition described in the MCAI 

and service information. The FAA is 

issuing this AD because the agency 

evaluated all the relevant information 

provided by Transport Canada and 

determined the unsafe condition 

described previously is likely to exist or 

develop in other products of the same 

type design.

specifies procedures for manually 

calculating the correct, current LCF 

cycle count for the impeller and HPC 

rotor and provides the formula for 

manually calculating the accumulated 

total cycles for the impeller and HPC 

rotor. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require the 

use of the manual LCF counting method 

in place of the ADTS counting method 

to determine the number of cycles 

accrued by the impeller and HPC rotor. 

Interim Action 

The FAA considers that this proposed 

AD would be an interim action. If final 

action is later identified, the FAA might 

consider additional rulemaking. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 66 

engines installed on helicopters of U.S. 

registry. 

The FAA estimates the following 

costs to comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Manually calculate LCF cycles ....................... 1 work-hour × $85 per hour = $85 ................. $0 $85 $5,610 

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. 

The FAA is 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 

The FAA 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. 

For the reasons discussed above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.

(e) Unsafe Condition 

This AD was prompted by a report from 

the manufacturer that the Automated Damage 

Tracking System (ADTS) may under-count 

the number of cycles accrued by the impeller 

and the high-pressure compressor (HPC) 

rotor, which could result in the failure of 

these components. The FAA is issuing this 

AD to prevent failure of the impeller and the 

HPC rotor. The unsafe condition, if not 

addressed, could result in the uncontained 

release of the impeller or the HPC rotor, 

damage to the engine, damage to the 

helicopter, and loss of control of the 

helicopter. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Required Actions 

Before exceeding 7,000 starts or 14,000 

flight cycles since new (CSN) on the affected 

engine, or prior to removal of the engine from 

the aircraft for the purpose of sending the 

engine to a repair or overhaul facility, 

whichever occurs first after the effective date 

of this AD: 

(1) Use the manual low-cycle fatigue (LCF) 

counting method to determine the 

accumulated LCF cycles for the impeller and 

the HPC rotor using paragraph 3., 

Accomplishment Instructions, of P&WC Alert 

Service Bulletin (ASB) PW210–72–A57142, 

Revision 1, dated March 26, 2020 or PW210– 

72–A57143, Revision 1, dated March 26, 

2020, as applicable for the engine model. 

(2) After performing the actions required 

by paragraph (g)(1) of this AD, use the 

manual LCF counting method specified in 

paragraph (g)(1) of this AD to count 

subsequent LCF cycles on the impeller and 

HPC rotor. Do not use the ADTS to count 

subsequent LCF cycles on the impeller or the 

HPC rotor. 

(h) Definition 

For the purpose of this AD, a ‘‘start’’ is an 

engine start followed by one or more flights. 

(i) Alternative Methods of Compliance
