SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposal. Send your comments to 

an address listed under the ADDRESSES

section. Include ‘‘Docket No. FAA– 

2017–0792; Product Identifier 2017– 

NE–28–AD’’ at the beginning of your

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 NPRM. 

Discussion 

We became aware of an unsafe 

condition from an uncontained failure 

of an HPT stage 2 disk that resulted in 

a fire. This unsafe condition was also 

determined to exist on some HPT stage 

1 disks. This condition, if not corrected, 

could result in uncontained HPT disk 

release, damage to the engine, and 

damage to the airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed GE Service Bulletin (SB) 

CF6–80C2 S/B 72–1562, Revision 01, 

dated July 28, 2017. The SB describes 

procedures for UI of HPT stage 1 and 2 

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 require UI 

of HPT stage 1 and 2 disks. 

Costs of Compliance 

We estimate that this proposed AD 

affects 640 engines installed on 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD:

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 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, 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

I. Synopsis 

In the 2007 700 MHz Second Report 

and Order,1 the Commission adopted 

rules for relicensing of 700 MHz Lower 

A, B, and E Block, and Upper C Block 

spectrum that is returned to the 

Commission’s inventory as a result of 

licensees’ failure to meet applicable 

construction requirements. The 

Commission set forth the overall rules 

and policies for the relicensing process 

and delegated authority to the Wireless 

Telecommunications Bureau (Bureau) to 

implement those rules and policies. To 

the extent the 700 MHz Second Report 

and Order and other Commission rules 

set forth elements of the relicensing 

process, the document cites to those 

rules, and otherwise seeks comment on
