AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding 

airworthiness directive (AD) 2011–26– 

04 for certain fuel injected reciprocating 

engines manufactured by Lycoming 

Engines. AD 2011–26–04 required 

inspection, replacement if necessary, 

and proper clamping of externally 

mounted fuel injector fuel lines. This 

new AD retains the requirements of AD 

2011–26–04, and expands the list of 

affected engine models. This AD was 

prompted by revised service 

information that added engine models 

to the applicability. We are issuing this 

AD to prevent failure of the fuel injector 

fuel lines, which could lead to 

uncontrolled engine fire, engine 

damage, and damage to the airplane. 

DATES: This AD is effective November 3, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of November 3, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2011–26–04, 

Amendment 39–16894 (76 FR 79051, 

December 21, 2011), (‘‘AD 2011–26– 

04’’). AD 2011–26–04 applied to certain 

fuel injected reciprocating engines 

manufactured by Lycoming Engines. 

The NPRM published in the Federal 

Register on November 25, 2013 (78 FR 

70240). The NPRM was prompted by 

revised service information that added 

engine models to the applicability. The 

NPRM proposed to expand the scope by 

adding the IO–540–C1C5 and IO–540– 

D4B5 engine models and requiring 

inspection, replacement if necessary, 

and proper clamping of externally 

mounted fuel injector fuel lines. We are 

issuing this AD to prevent failure of the 

fuel injector fuel lines, which could lead 

to uncontrolled engine fire, engine 

damage, and damage to the airplane. 

Related Service Information Under 1 

CFR Part 51 

We reviewed Lycoming Engines 

Mandatory Service Bulletin (MSB) No. 

342G, dated July 16, 2013; Supplement 

No. 1 to MSB No. 342G, dated August 

29, 2013; and Supplement No. 2 to MSB 

No. 342G, dated January 23, 2014. The 

service information describes 

procedures for fuel line and support 

clamp inspection and installation. 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 of 

this AD. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 


asabaliauskas on DSK5VPTVN1PROD with RULES
58340 Federal Register / Vol. 80, No. 188 / Tuesday, September 29, 2015 / Rules and Regulations 

received on the proposal and the FAA’s 

response to each comment. 

Request To Add an Engine Model 

Aerotech Publications and an 

individual commenter requested that 

the Lycoming LIO–360–M1A be added 

to the AD. The justification given was 

that the type certificate data sheet, 1E10, 

shows the LIO–360–M1A to be identical 

to the IO–360–M1A except with counter 

rotation. Additionally, unless specific 

engine models are listed in the AD, 

exempting those engines with 

maintenance manuals would prevent 

the maintenance technician from 

knowing which engines are exempt. 

We disagree. The engine certification 

basis determines if an engine model’s 

mandatory maintenance will be 

managed by a dedicated engine 

maintenance manual (EMM) with an 

airworthiness limitations section (ALS) 

or by manufacturer’s service bulletins 

(SBs). Engines certified to 14 CFR 33, as 

was LIO–360–M1A, have a dedicated 

EMM with an ALS that includes the fuel 

tube inspection in Section 05–00–00. 

We did not change this AD. 

Request To Add Service Information 

Lycoming Engines requested that 

Lycoming SB 342G, Supplement No. 2, 

dated January 23, 2014 be added to this 

AD. Lycoming said that SB 342G, 

Supplement No. 2 removes the eight 

inch spacing dimension between clamps 

and corrects Diagram No. 30 for the IO– 

540–M1C5 engine model. 

We agree. We changed this AD to 

include Lycoming SB 342G, 

Supplement No. 2. 

Request To Allow Previously Approved 

Alternative Methods of Compliance 

(AMOCs) 

Central Airlines requested that 

AMOCs previously approved in AD 

2008–14–07 and AD 2011–26–04 be 

allowed for use in this AD. 

We agree. We changed the AMOC 

paragraph in this AD by adding: 

‘‘AMOCs previously approved for AD 

2008–14–07, Amendment 39–15602 (73 

FR 39574, July 10, 2008) (‘‘AD 2008–14– 

07’’) and AD 2011–26–04, Amendment 

39–16894 (76 FR 79051, December 21, 

2011) (‘‘AD 2011–26–04’’) are approved 

as AMOCs to the corresponding 

requirements in paragraph (e) of this 

AD.’’ 

Request To Change Applicability 

An anonymous commenter requested 

that Continental and Jacobs R–755 

engines, be added to the applicability of 

this AD. There was no justification 

provided for the request to add 

Continental engine(s). The commenter 

said that the Jacobs R–755 engine uses 

the same fuel units and Lycoming fuel 

injector tubes. 

We disagree. We have received no 

data to indicate that any other engines, 

including Continental engines, have the 

same problem as the Lycoming engines. 

We also do not agree with adding the 

Jacbos R–755 engine to the applicability 

because the unsafe condition for this AD 

concerns missing or improperly 

clamped fuel injector fuel lines. We 

have received no reports of problems 

with fuel injector fuel lines for the R– 

755; therefore, the R–755 engine does 

not need to be included in this AD. We 

did not change this AD. 

Correction to Applicability 

Since we issued the NPRM (78 FR 

70240, November 25, 2013) (‘‘the 

NPRM’’), we determined that a 

discussion of a change to the engine 

model applicability was omitted from 

the NPRM. Engine model LIO–360–M1A 

was removed from the Applicability 

paragraph in this AD because the fuel 

tube inspections are documented in the 

ALS for this engine model. 

We also determined that the NPRM 

incorrectly stated that the proposed AD 

action would add three engine models 

to the applicability list of the affected 

engines. The NPRM added two engine 

models, the IO–540–C1C5 and IO–540– 

D4B5, to applicability list of affected 

engines. 

Correction to the Costs of Compliance 

Since we issued the NPRM, we 

determined that the Costs of 

Compliance paragraph was incorrect. 

We changed the Costs of Compliance 

paragraph in this AD to correct that 

error. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this AD 

with the changes described previously. 

We have determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

correcting the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

We also 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 will affect 

about 37,270 engines installed on 

airplanes of U.S. registry. We also 

estimate that it will require 1 hour to 

inspect 19,081 four cylinder engines, 1.5 

hours to inspect 18,000 six cylinder 

engines, and 2 hours to inspect 189 

eight cylinder engines. The average 

labor rate is $85 per hour. Based on 

these figures, we estimate the cost of 

this AD on U.S. operators to be 

$3,949,015. 

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 

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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Is not a ‘‘significant rule’’ under 

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.

determine if your engine has a Maintenance 

and Overhaul Manual you can either contact 

Lycoming, or you can refer to Lycoming’s list 

of maintenance publications for engines that 

have a Maintenance and Overhaul Manual. 

(d) Unsafe Condition 

This AD was prompted by revised service 

information that added engine models to the 

applicability. This service information adds 

engine models requiring inspection and 

technical updates. We are issuing this AD to 

prevent failure of the fuel injector fuel lines, 

which could lead to uncontrolled engine fire, 

engine damage, and damage to the airplane. 

(e) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(1) Initial Inspections 

(i) Within 10 hours time-in-service (TIS) 

after the effective date of this AD, inspect the 

fuel injector fuel lines and clamps between 

the fuel manifold and the fuel injector 

nozzles. Use Lycoming Engines Mandatory 

Service Bulletin (MSB) No. 342G, dated July 

16, 2013; Supplement No. 1 to MSB No. 

342G, dated August 29, 2013; and 

Supplement No. 2 to MSB No. 342G, dated 

January 23, 2014 to perform the inspection. 

Replace any fuel injector fuel line or clamp 

that fails the inspection required by the Fuel 

Line Inspection and Installation Checklist in 

MSB No. 342G. 

(ii) Thereafter, re-inspect after any 

maintenance is done on the engine where 

any clamp on a fuel injector fuel line was 

disconnected, moved, or loosened, and 

within every 110 hours TIS and after each 

engine overhaul. Use Lycoming Engines MSB 

No. 342G, dated July 16, 2013; Supplement 

No. 1 to MSB No. 342G, dated August 29, 

2013; and Supplement No. 2 to MSB No. 

342G, dated January 23, 2014 to perform the 

inspection and the Fuel Line Inspection and 

Installation Checklist in MSB No. 342G to 

perform the re-inspection. 

(f) Credit for Previous Actions 

If you inspected your fuel injector fuel 

lines and clamps using Lycoming Engines 

MSB No. 342F, dated June 4, 2010, or earlier 

versions, you met the initial inspection 

requirements of this AD. However, you must 

still comply with the repetitive inspection 

requirements of paragraph (e)(1)(ii) of this 

AD.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

PILATUS AIRCRAFT LTD. Models PC– 

12, PC–12/45, and PC–12/47E airplanes. 

This AD results from mandatory 

continuing airworthiness information 

(MCAI) issued by an aviation authority 

of another country to identify and 

correct an unsafe condition on an 

aviation product. The MCAI describes 

the unsafe condition as a malfunction of 

the universal joint. We are issuing this 

AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective November 3, 

2015. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of November 3, 2015.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to adding an AD that would 

apply to PILATUS AIRCRAFT LTD. 

Model PC–12, PC–12/45, and PC–12/ 

47E airplanes. The NPRM was 

published in the Federal Register on 

July 14, 2015 (80 FR 40949). The NPRM 

proposed to correct an unsafe condition 

for the specified products and was 

based on mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country. The MCAI states: 

A case of malfunctioning was reported of 

a universal joint installed between the 

control tube assembly and the control 

column on a PC–12/47E aeroplane. 

Investigation determined that the 

malfunction was caused by an incorrectly 

manufactured universal joint. Universal 

joints from the same manufacturing batch 

were provided to operators between 01 

March 2014 and 28 February 2015, and are 

thus potentially affected. 

This condition, if not corrected, could lead 

to other cases of malfunctioning of a 

universal joint, possibly resulting in reduced 

control of the aeroplane. 

To address this potential unsafe condition, 

Pilatus Aircraft Ltd. issued Service Bulletin 

(SB) No. 27–022 to provide instructions for 

replacement of the universal joints in the 

flight controls. 

For the reason described above, this 

AD requires removal from service of the 

potentially incorrectly manufactured 

universal joints. The MCAI can be found 

in the AD docket on the Internet at: 

http://www.regulations.gov/

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (80 

FR 40949, July 14, 2015) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the relevant data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed except for minor editorial 

changes. We have determined that these 

minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (80 FR 

40949, July 14, 2015) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already
