AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Honeywell International Inc. TFE731–4, 

–4R, –5AR, –5BR, and –5R turbofan 

engines. This proposed AD was 

prompted by a report of certain 

interstage turbine transition (ITT) ducts 

failing to meet containment capability 

requirements. This proposed AD would 

require replacing certain ITT ducts. We 

are proposing this AD to prevent failure 

of the ITT duct, which could lead to an 

uncontained part release, damage to the 

engine, and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by December 28, 2015 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to

Discussion 

While the Honeywell Aerospace 

Olomouc facility in the Czech Republic 

was reworking certain ITT ducts, 

forgings that were not properly heat 

treated were installed on the affected 

engines. The heat treatment is necessary 

for the ITT ducts, part number (P/N) 

3075292–4, to meet mechanical 

properties and the containment 

capability requirements of the ITT duct 

design. ITT ducts with unacceptable 

containment capability, if not corrected, 

could result in an uncontained part 

release, damage to the engine, and 

damage to the airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Honeywell Service 

Bulletin (SB) No. TFE731–72–3789, 

dated March 23, 2015. The SB describes 

procedures for removing affected ITT 

ducts. 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. 

FAA’s Determination 

We are proposing this NPRM 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 NPRM would require replacing 

certain ITT ducts, P/N 3075292–4. 

Costs of Compliance 

We estimate that this proposed AD 

affects 47 engines installed on airplanes 

of U.S. registry. We also estimate that it 

would take about 2 hours per engine to 

comply with this proposed AD. The 

average labor rate is $85 per hour. We 

estimate that replacement parts would 

cost $15,000 per engine. Based on these 

figures, we estimate the total cost of the 

proposed AD to U.S. operators to be 

$712,990. Our cost estimate is exclusive 

of possible warranty coverage. 

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 


rmajette on DSK7SPTVN1PROD with PROPOSALS
66482 Federal Register / Vol. 80, No. 209 / Thursday, October 29, 2015 / Proposed Rules 

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. 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA proposes to amend 14 CFR part 

39 as follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive (AD): 

Honeywell International Inc. (Type 

Certificate previously held by 

AlliedSignal Inc., Garrett Turbine 

Engine Company): Docket No. FAA– 

2015–2208; Directorate Identifier 2015– 

NE–19–AD. 

(a) Comments Due Date 

We must receive comments by December 

28, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to all Honeywell 

International Inc. TFE731–4, –4R, –5AR, 

–5BR, and –5R turbofan engines with an 

interstage turbine transition (ITT) duct, part 

number (P/N) 3075292–4, installed, with a 

serial number (S/N) listed in Table 2 of 

Honeywell Service Bulletin (SB) No. 

TFE731–72–3789, dated March 23, 2015. 

(d) Unsafe Condition 

This AD was prompted by a report of 

certain ITT ducts failing to meet containment 

capability requirements. We are issuing this 

AD to prevent failure of the ITT duct, which 

could lead to an uncontained part release, 

damage to the engine, and damage to the 

airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) At the next removal of the ITT duct 

from the engine not to exceed 2,600 hours 

time-in-service after the effective date of this 

AD, remove the affected ITT duct and replace 

with a part eligible for installation. 

(2) Reserved. 

(f) Definitions 

For the purpose of this AD a part eligible 

for installation is an ITT duct with an S/N 

that is not listed in Table 2 of Honeywell SB 

No. TFE731–72–3789, dated March 23, 2015 

or, if listed in Table 2 of this SB, was 

reworked using Honeywell SB No. TFE731– 

72–3789, dated March 23, 2015. 

(g) Installation Prohibition 

After the effective date of this AD, do not 

install any ITT duct with an S/N listed in 

Table 2 of Honeywell SB No. TFE731–72– 

3789, dated March 23, 2015, onto any engine, 

unless the ITT duct is marked with the 

overhaul/repair instructions number 

‘‘P35864’’ near the ITT duct P/N and S/N 

markings. 

(h) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Los Angeles Aircraft 

Certification Office, FAA, may approve 

AMOCs for this AD. Use the procedures 

found in 14 CFR 39.19 to make your request.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for B–N 

Group Ltd. Models BN–2, BN–2A, BN– 

2A–2, BN–2A–3, BN–2A–6, BN–2A–8,

III, BN2A MK. III–2, and BN2A MK. III– 

3 airplanes that would supersede AD 

2014–03–18. This proposed AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as damage of the cable sliding 

end assembly and installation of the 

incorrect end fitting on engine control 

cable assemblies. We are issuing this 

proposed AD to require actions to 

address the unsafe condition on these 

products. 

DATES: We must receive comments on 

this proposed AD by December 14, 

2015. 

ADDRESSES: You may send comments by 

any of the following methods:
