Airworthiness Directives; Lycoming 

Engines 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 

serial number Lycoming Engines 

reciprocating engines. This proposed 

AD was prompted by events of propeller 

governor shaft set screws coming loose 

due to improper installation, which 

could result in engine oil loss, damage 

to the engine, and damage to the 

airplane. This proposed AD would 

require application of Loctite 290, or 

equivalent, to the threads of the 

propeller governor shaft set screw at 

each installation of the set screw in 

addition to the peening of crankcase 

hole threads. We are proposing this AD 

to prevent the propeller governor shaft 

set screw from coming loose, causing 

damage to the engine, and damage to the 

airplane. 

DATES: We must receive comments on 

this proposed AD by November 10, 

2014. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

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– 

2014–0540; Directorate Identifier 2014– 

NE–10–AD’’ at the beginning of your 

comments. We specifically invite 

comments on the overall regulatory, 

economic, environmental, and energy 

aspects of this proposed AD. We will 

consider all comments received by the 

closing date and may amend this 

proposed AD 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 proposed AD. 

Discussion 

We issued Special Airworthiness 

Information Bulletin (SAIB) NE–08–32 

on July 3, 2008. The SAIB 

recommended actions to correct the 

condition of a propeller governor shaft 

set screw coming loose. This proposed 

AD was prompted by additional events 

of propeller governor shaft set screws 

coming loose due to improper 

installation, which could result in the 

shaft penetrating the plug at the front of 

the crankcase and causing a loss of 

engine oil and a loss of engine power. 

In some reported events, engine oil was 

deposited on the windshield, restricting 

pilot visibility. The loose set screw 

could also enter the rotating system and 

cause damage to the camshaft and valve 

lifters. Safety is further diminished if 

failure occurs during aerobatic 

maneuvers, especially at low altitudes, 

due to reduction in pilot reaction time. 

These conditions, if not corrected, could 

result in damage to the engine, and 

damage to the airplane. This proposed 

AD would require application of Loctite 

290, or equivalent, to the threads of the 

propeller governor shaft set screw at 

each installation of the set screw in 

addition to the peening of crankcase 

hole threads. We are proposing this AD 

to prevent the propeller governor shaft 

set screw from coming loose, causing 

damage to the engine, and damage to the 

airplane. 

Relevant Service Information 

We reviewed Lycoming Engines 

Service Instruction (SI) No. 1343B, 

dated June 15, 2007. The SI describes 

procedures for securing the propeller 

governor shaft set screw. 

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 these same 

type designs. 

Proposed AD Requirements 

This proposed AD would require 

application of Loctite 290, or equivalent, 

to the threads of the propeller governor 

shaft set screw at each installation of the 

set screw in addition to the peening of 

crankcase hole threads. 

Differences Between This Proposed AD 

and the Service Information 

Lycoming Engines SI No. 1343B, 

dated June 15, 2007, specifies the use of 

Loctite 290, in addition to peening of 

the crankcase hole threads, to secure the 

set screw in place. This AD allows the 

use of Loctite 290, or equivalent threadlocking, anaerobic, single-component 

sealing compound that meets military 

specification Mil-S–46163A, Type III, 

Grade R. The SI also requires these 

actions at next overhaul, whereas this 

AD requires these actions at any 

installation of the propeller governor 

shaft set screw. 

Costs of Compliance 

We estimate that this proposed AD 

would affect about 2,330 engines 

installed on airplanes of U.S. registry. 

We also estimate that it will take about 

0.1 hours per engine to comply with this 

AD. The average labor rate is $85 per 

hour. Prorated parts life will cost about 

$1 per engine. Based on these figures, 

we estimate the cost of this proposed 

AD on U.S. operators to be $22,135. 

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 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,

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede 

airworthiness directive (AD) 2013–15– 

10 that applies to certain Rolls-Royce 

(RR) RB211 turbofan engines. AD 2013– 

15–10 requires inspecting the 

intermediate-pressure compressor (IPC) 

rotor shaft rear balance land for cracks. 

This AD eliminates a terminating action, 

expands one inspection and eliminates 

others. This proposed AD would require 

inspecting the IPC rotor shaft rear 

balance land for cracks and eliminate 

certain other inspections. We are 

proposing this AD to detect cracking on 

the IPC rotor shaft rear balance land, 

which could lead to uncontained engine 

failure and damage to the airplane. 

DATES: We must receive comments on 

this proposed AD by November 10, 

2014.
