14 CFR Part 39 

[Docket No. FAA–2015–0625; Directorate

Airworthiness Directives; GE Aviation 

Czech s.r.o. Turboprop Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

serial number (S/N) GE Aviation Czech 

s.r.o. M601E–11, M601E–11A, and 

M601F turboprop engines with certain 

part number (P/N) gas generator turbine 

(GGT) blades, installed. This AD 

requires removing from service any 

affected engine with certain GGT blades 

installed. This AD was prompted by the 

determination that certain GGT blades 

are susceptible to blade failure. We are 

issuing this AD to prevent GGT blade 

failure, which could lead to engine 

failure and loss of the airplane. 

DATES: This AD becomes effective 

October 1, 2015. 

ADDRESSES: See the FOR FURTHER

INFORMATION CONTACT section.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to the specified products. The 

NPRM was published in the Federal 

Register on April 21, 2015 (80 FR 

22136). The NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

It has been demonstrated that non-shot 

peened Gas Generator Turbine (GGT) blades 

are susceptible to blade separation in the 

shank area due to their reduced fatigue life. 

This condition, if not corrected, could lead 

to an in-flight engine shutdown and, 

consequently, reduced control of the 

aeroplane. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 22136, April 21, 2015). 

In our review of the NPRM, we found 

that we had included an S/N from the 

MCAI that was in error. We corrected 

the error by removing S/N 961001 from 

paragraph (c)(2) of this AD. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of 

this AD. 

Costs of Compliance 

We estimate that this AD affects one 

engine installed on an airplane of U.S. 

registry. We also estimate that it would 

take about 64 hours per engine to 

comply with this AD. The average labor 

rate is $85 per hour. Required parts cost 

about $28,765 per engine. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators to be $34,205. 

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 

We determined that 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 this AD: 

(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.

51936 Federal Register / Vol. 80, No. 166 / Thursday, August 27, 2015 / Rules and Regulations 

Adoption of the Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 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): 

2015–17–20 GE Aviation Czech s.r.o. (Type 

Certificate previously held by WALTER 

Engines a.s., Walter a.s., and 

MOTORLET a.s.): Amendment 39– 

18253; Docket No. FAA–2015–0625; 

Directorate Identifier 2015–NE–09–AD. 

(a) Effective Date 

This AD becomes effective October 1, 2015. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to certain serial number 

(S/N) GE Aviation Czech s.r.o. M601E–11, 

M601E–11A, and M601F turboprop engine 

models, with gas generator turbine (GGT) 

blade, part number (P/N) M601–3372.6 or 

M601–3372.51, installed, as follows: 

(1) Model M601E–11: S/Ns 862001, 

863008, 894018, 034005, 034006, 034007, 

034008, 041003, and 042002. 

(2) Model M601E–11A: S/Ns 042003, 

042004, 044001, and 044002. 

(3) Model M601F: S/Ns 024001, 002001, 

003001, 934001, 934002, 961001. 

(d) Reason 

This AD was prompted by the 

determination that certain GGT blades are 

susceptible to blade failure. These blades are 

identified as blade P/Ns M601–3372.6 and 

M601–3372.51, and are installed on an 

engine S/N identified in paragraph (c) of this 

AD. We are issuing this AD to prevent GGT 

blade failure, which could lead to engine 

failure and loss of the airplane. 

(e) Actions and Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. After the effective date of this AD: 

(1) Do not return to service any affected 

engine with GGT blade, P/N M601–3372.6 or 

M601–3372.51, installed, after 300 hours 

time in service or six months, whichever 

occurs first, after the effective date of this 

AD. 

(2) If the affected engines are subsequently 

disassembled or overhauled, the non-shot 

peened GGT blades, P/N M601–3372.6 or 

M601–3372.51, are not eligible for 

installation in any other engine after removal. 

(f) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office, 

FAA, may approve AMOCs for this AD. Use 

the procedures found in 14 CFR 39.19 to 

make your request. You may email your 

request to: ANE–AD–AMOC@faa.gov.

SUPPLEMENTARY INFORMATION: 

History 

FAA Order 7400.9Y, Airspace 

Designations and Reporting Points, 

effective September 15, 2014, listed 

Class A, B, C, D and E airspace areas; 

air traffic service routes; and reporting 

points. Due to the length of these 

descriptions, the FAA requested 

approval from the Office of the Federal 

Register to incorporate the material by 

reference in the Federal Aviation 

Regulations section 71.1, effective 

September 15, 2014, through September 

15, 2015. During the incorporation by 

reference period, the FAA processed all 

proposed changes of the airspace 

listings in FAA Order 7400.9Y in full 

text as proposed rule documents in the 

Federal Register. Likewise, all 

amendments of these listings were 

published in full text as final rules in 

the Federal Register. This rule reflects 

the periodic integration of these final 

rule amendments into a revised edition 

of Order 7400.9Z, Airspace Designations 

and Reporting Points. The Director of 

the Federal Register has approved the 

incorporation by reference of FAA 

Order 7400.9Z in section 71.1, as of 

September 15, 2015, through September 

15, 2016. This rule also explains the 

procedures the FAA will use to amend 

the airspace designations incorporated 

by reference in part 71. Sections 71.5,
