Airworthiness Directives; Honeywell 

International Inc. Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

Airworthiness Directive (AD) 2017–20– 

01, which applies to certain Honeywell 

International Inc. (Honeywell) TFE731– 

20 and TFE731–40 turbofan engines. AD 

2017–20–01 requires removing the 

affected fan disk and replacing it with 

a fan disk eligible for installation. Since 

we issued AD 2017–20–01, we 

determined that some turbofan engine 

models were omitted from the 

applicability of AD 2017–20–01. This 

proposed AD would add these turbofan 

engine models to the applicability, 

remove the Honeywell TFE731–20 

turbofan engine from the applicability, 

and prohibit installation of affected fan 

disks. We are proposing this AD to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by October 29, 2018. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Discussion 

We issued AD 2017–20–01, 

Amendment 39–19058 (82 FR 45173, 

September 28, 2017), (‘‘AD 2017–20– 

01’’), for certain Honeywell TFE731–20 

and TFE731–40 turbofan engines with 

fan disk part number, (P/N) 3060287–2, 

and a serial number (S/N) listed in 

Table 9 of Honeywell Service Bulletin 

(SB) TFE731–72–5256, Revision 0, 

dated October 7, 2016. AD 2017–20–01 

requires removing the affected fan disk 

and replacing it with a part eligible for 

installation. AD 2017–20–01 resulted 

from two fan disks found with surface 

rollovers in the dovetail slot area. We 

issued AD 2017–20–01 to address the 

unsafe condition on these products. 

Actions Since AD 2017–20–01 Was 

Issued 

Since we issued AD 2017–20–01, we 

determined that Honeywell TFE731– 

20R, –20AR, –20BR, and TFE731–40R, 

–40AR, and –40BR turbofan engine 

models listed in Honeywell SB TFE731– 

72–5256, Revision 0, dated October 7, 

2016, were omitted from the 

applicability of AD 2017–20–01. We 

also determined that the Honeywell 

TFE731–20 turbofan engine model was 

never produced and should be removed 

from the applicability; and that affected 

fan disks, P/N 3060267–2, should be 

prohibited from installation unless they 

have ‘‘T43374’’ marked adjacent to the 

engine P/N or S/N. This proposed AD 

would add Honeywell TFE731–20R, 

–20AR, –20BR, and TFE731–40R, 

–40AR, and –40BR turbofan engine 

models to the applicability, remove the 

Honeywell TFE731–20 turbofan engine 

from the applicability, and prohibit 

installation of affected fan disks. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Honeywell SB TFE731– 

72–5256, Revision 0, dated October 7, 

2016. The SB identifies affected fan 

disks by S/N and describes procedures 

for removing, inspecting, and replacing 

the affected fan disks. 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. 

FAA’s Determination 

We are proposing 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 the same 

type design. 

Proposed AD Requirements 

This proposed AD would retain 

certain requirements of AD 2017–20–01. 

This proposed AD would add 

Honeywell TFE731–20R, –20AR, –20BR, 

and TFE731–40AR, –40BR, and –40R 

turbofan engines with fan disk, P/N 

3060287–2, and a S/N listed in Table 9 

of Honeywell SB TFE731–72–5256, 

Revision 0, dated October 7, 2016. This 

proposed AD would also remove the 

Honeywell TFE731–20 turbofan engine 

from the applicability and prohibit 


daltland on DSKBBV9HB2PROD with PROPOSALS
Federal Register / Vol. 83, No. 179 / Friday, September 14, 2018 / Proposed Rules 46665 

installation of affected fan disks that do 

not have ‘‘T43374’’ marked adjacent to 

the engine P/N or S/N. 

Costs of Compliance 

We estimate that this proposed AD 

affects 61 engines installed on airplanes 

of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

Remove fan disk and send to Honeywell for 

inspection.

8 work-hours × $85 per hour = $680 ............. $0 $680 $41,480 

Install reworked or new fan disk ..................... 26 work-hours × $85 per hour = $2,210 ........ 0 2,210 134,810 

The new requirements of this 

proposed AD add no additional 

economic burden. We estimate the 

following costs to do any necessary fan 

disk replacements that would be 

required based on the results of the 

proposed inspection. We estimate that 6 

engines will need this replacement. 

ON-CONDITION COSTS

Action Labor cost Parts cost Cost per 

product 

Replace the non-serviceable disk with a new fan disk 1 work-hour × $85 per hour = $85 ............................... $50,000 $50,085 

According to the manufacturer, some 

of the costs of this proposed AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

individuals. We do not control warranty 

coverage for affected individuals. As a 

result, 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. 

This AD is issued in accordance with 

authority delegated by the Executive 

Director, Aircraft Certification Service, 

as authorized by FAA Order 8000.51C. 

In accordance with that order, issuance 

of ADs is normally a function of the 

Compliance and Airworthiness 

Division, but during this transition 

period, the Executive Director has 

delegated the authority to issue ADs 

applicable to engines, propellers, and 

associated appliances to the Manager, 

Engine and Propeller Standards Branch, 

Policy and Innovation Division. 

Regulatory Findings 

We have 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 that the 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, 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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety.
