Airworthiness Directives; Lycoming 

Engines, Fuel Injected Reciprocating 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to supersede an 

existing airworthiness directive (AD) 

that applies to certain fuel injected 

reciprocating engines manufactured by 

Lycoming Engines. The existing AD 

currently requires inspection, 

replacement if necessary, and proper 

clamping of externally mounted fuel 

injector fuel lines. That AD also 

exempts engines that have a 

Maintenance and Overhaul Manual with 

an Airworthiness Limitations Section 

that requires inspection and 

replacement, if necessary, of externally 

mounted fuel injector lines. This 

proposed AD would require the same 

actions. Since we issued that AD, 

Lycoming Engines revised their 

Mandatory Service Bulletin (MSB) to 

add engine models requiring 

inspections. We are proposing this AD 

to prevent failure of the fuel injector 

fuel lines that would allow fuel to spray 

into the engine compartment, resulting 

in an engine fire. 

DATES: We must receive comments on 

this proposed AD by April 1, 2011. 

ADDRESSES: You may send comments by 

any of the following methods: 

• Federal eRulemaking Portal: Go to 

http://www.regulations.gov. Follow the 

instructions for submitting comments.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

We invite you to send any written 

relevant data, views, or arguments about 

this proposed AD. Send your comments 

to an address listed under the 

ADDRESSES section. Include ‘‘Docket No. 

FAA–2007–0218; Directorate Identifier 

92–ANE–56–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://

Discussion 

On June 24, 2008, we issued AD 

2008–14–07, Amendment 39–15602 (73 

FR 39574), for certain fuel injected 

reciprocating engines manufactured by 

Lycoming Engines. That AD requires 

inspection, replacement if necessary, 

and proper clamping of externally 

mounted fuel injector fuel lines. Some 

of the clamps are difficult to install on 

the fuel injector lines and then to the 

engine, resulting in support clamps 

being omitted during field overhaul or 

repair. Lines not clamped correctly are 

subject to engine vibration and wear. 

That AD resulted from Lycoming 

Engines revising their MSB to add 

engine models requiring inspection, and 

from the need to clarify a repetitive 

inspection compliance time. We issued 

that AD to prevent failure of the fuel 

injector fuel lines that would allow fuel 

to spray into the engine compartment, 

resulting in an engine fire. 

Actions Since Existing AD Was Issued 

Since we issued AD 2008–14–07, 

Lycoming Engines revised their MSB to 

add engine models requiring inspection, 

replacement if necessary, and proper 

clamping of externally mounted fuel 

injector fuel lines. They also listed some 

of the physical damages that would 

reject a tube. Based on that MSB 

revision, we would require the 

inspection in this proposed AD 

supersedure to meet all conditions 

specified in MSB No. 342F, dated June 

4, 2010. In addition, we learned that two 

engines listed in AD 2008–14–07 do not 

exist. They are the IO–360–C2G6 and 

the TIO–540AE1A5, so we removed 

them from this proposed AD. 

Relevant Service Information 

We reviewed Lycoming Engines MSB 

No. 342F, dated June 4, 2010. The MSB 

describes procedures for inspecting, and 

if necessary replacing the fuel injector 

fuel lines. That MSB supersedes Textron 

Lycoming MSB No. 342E, 342D, MSB 

No. 342C, MSB No. 342B, Supplement 

No. 1 to MSB 342B, MSB 342A, and 

MSB 342.

8662 Federal Register / Vol. 76, No. 31 / Tuesday, February 15, 2011 / Proposed Rules 

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 retain all of 

the requirements of AD 2008–14–07. 

This proposed AD would add the LIO– 

360–M1A engine, as applicable. 

Costs of Compliance 

We estimate that this proposed AD 

affects 21,180 four-cylinder engines, 

21,449 six-cylinder engines, and 256 

eight-cylinder engines installed on 

aircraft of U.S. registry. We also estimate 

that it would take about 0.2 work-hour 

to inspect all lines on a four-cylinder 

engine, 0.5 work-hour to inspect all 

lines on a six-cylinder engine, and 0.7 

work-hour to inspect all lines on an 

eight-cylinder engine. We also estimate 

that the average labor rate is $85 per 

work-hour. We do not anticipate any 

additional costs on U.S. operators, as 

the inspection would be done in 

conjunction with other work performed 

concurrently. We anticipate no parts to 

be required. Based on these figures, the 

total cost of the proposed AD to U.S. 

operators for one inspection of the fleet 

is $1,372,645. 

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 have 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 that the 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 

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 

removing airworthiness directive (AD) 

2008–14–07, Amendment 39–15602 (73 

FR 39574), and adding the following 

new AD: 

Lycoming Engines (formerly Textron 

Lycoming Division, AVCO Corporation): 

Docket No. FAA–2007–0218; Directorate 

Identifier 92–ANE–56–AD. 

Comments Due Date 

(a) The FAA must receive comments on 

this AD action by April 1, 2011. 

Affected ADs 

(b) This AD supersedes AD 2008–14–07, 

Amendment 39–15602. 

Applicability 

(c) This AD applies to fuel injected 

reciprocating engines manufactured by 

Lycoming Engines that incorporate externally 

mounted fuel injection lines (engines with an 

‘‘I’’ in the prefix of the engine model 

designation) as listed in the following Table

lines) has been disconnected, moved, or 

loosened, in accordance with paragraph (k) of 

this AD. 

Inspection Criteria 

(k) Inspect the fuel injector fuel lines and 

clamps between the fuel manifold and the 

fuel injector nozzles, and replace as 

necessary any fuel injector fuel line and 

clamp that does not meet all conditions 

specified in Lycoming Engines MSB No.
