Airworthiness Directives; Technify 

Motors GmbH Reciprocating Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

Technify Motors GmbH (type certificate 

previously held by Thielert Aircraft 

Engines GmbH) TAE 125–02–99 and 

TAE 125–02–114 reciprocating engines. 

This proposed AD was prompted by inflight shutdowns on airplanes with TAE 

125–02 engines. This proposed AD 

would require removal of each highpressure (HP) fuel pump before 300 

flight hours (FHs) in service or within 

55 FHs after the effective date of the AD, 

whichever occurs later. We are 

proposing this AD to prevent failure of 

the HP fuel pump, which could result 

in damage to the engine and damage to 

the airplane. 

DATES: We must receive comments on 

this proposed AD by July 22, 2014. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov and follow 

the instructions for sending your 

comments electronically.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA AD 2013– 

0279, dated November 26, 2013 

(referred to hereinafter as ‘‘the MCAI’’), 

to correct an unsafe condition for the 

specified products. The MCAI states: 

In-flight shut down occurrences have been 

reported on aeroplanes equipped with TAE 

125–02 engines. The initial results of the 

investigations showed that abnormal high 

wear of the high pressure fuel pumps was the 

probable cause of the engine failure. 

This condition, if not corrected, could 

result in further cases of engine power loss 

events and consequent potential loss of 

control of the aeroplane. 

We are proposing this AD to prevent 

damage to the engine and damage to the 

aircraft. You may obtain further 

information by examining the MCAI in 

the AD docket on the Internet at 

http://www.regulations.gov by searching 

for and locating it in Docket No. FAA– 

2014–0179. 

Relevant Service Information 

Technify Motors GmbH has issued 

Service Bulletin No. TM TAE 125–1017 

P1, Revision 1, dated September 20, 

2013. The service information describes 

procedures for removing and replacing 

the HP fuel pump. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of Germany, and 

is approved for operation in the United 

States. Pursuant to our bilateral 

agreement with the European 

Community, EASA has notified us of 

the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all 

information provided by EASA and 

determined the unsafe condition exists 

and is likely to exist or develop on other 

products of the same type design. This 

proposed AD would require removal of 

each affected HP fuel pump. 

Costs of Compliance 

We estimate that this proposed AD 

affects 160 engines installed on 

airplanes of U.S. registry. We also 

estimate that it would take about 1 hour 

per engine to comply with this proposed 

AD. The average labor rate is $85 per 

hour. Based on these figures, we 

estimate the cost of the proposed AD on 

U.S. operators to be $13,600. 

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 


sroberts on DSK5SPTVN1PROD with PROPOSALS
29694 Federal Register / Vol. 79, No. 100 / Friday, May 23, 2014 / Proposed Rules 

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.

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): 

Technify Motors GmbH (Type Certificate 

previously held by Thielert Aircraft 

Engines GmbH): Docket No. FAA–2014– 

0179; Directorate Identifier 2014–NE– 

03–AD. 

(a) Comments Due Date 

We must receive comments by July 22, 

2014. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to TAE 125–02–99 and 

TAE 125–02–114 reciprocating engines with 

a high-pressure (HP) fuel pump, part number 

(P/N) 05–7312–K005301 or P/N 05–7312– 

K005302. 

(d) Reason 

This AD was prompted by in-flight 

shutdowns on airplanes with TAE 125–02 

engines. We are issuing this AD to prevent 

failure of the HP fuel pump, which could 

result in damage to the engine and damage 

to the airplane. 

(e) Actions and Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. Remove each HP fuel pump, P/N 05– 

7312–K005301 and P/N 05–7312–K005302, 

before 300 flight hours (FHs) in service or 

within 55 FHs after the effective date of this 

AD, whichever occurs later. 

(f) Installation Prohibition 

After the effective date of this AD, do not 

install a TAE 125–02–99 or TAE 125–02–114 

engine with HP fuel pump, P/N 05–7312– 

K005301 or P/N 05–7312–K005302, onto any 

airplane. 

(g) Alternative Methods of Compliance 

(AMOCs) 

The Manager, Engine Certification Office,

Airworthiness Directives; Rolls-Royce 

plc Turbofan Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2013–12– 

01 that applies to all Rolls-Royce plc 

(RR) model RB211 Trent 768–60, 772– 

60, and 772B–60 turbofan engines. AD 

2013–12–01 requires a one-time 

ultrasonic inspection (UI) of lowpressure (LP) compressor blades with 

more than 2,500 flight cycles since new 

or last inspection. Since we issued AD 

2013–12–01, RR determined that 

repetitive UIs of the LP compressor 

blades are needed. This proposed AD 

would require initial and repetitive UIs 

of the affected LP compressor blades. 

We are proposing this AD to prevent LP 

compressor blade airfoil separations, 

damage to the engine, and damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by July 22, 2014. 

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
