Airworthiness Directives; Turbomeca 

S.A. Turboshaft 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 

Turbomeca S.A. Arriel 1A1, 1A2, 1B, 

1C, 1C1, 1C2, 1D, 1D1, 1E2, 1K1, 1S, 

and 1S1 turboshaft engines. This 

proposed AD was prompted by a ‘‘chip 

illumination event’’ in flight on a 

Turbomeca S.A. Arriel 1 engine. This 

proposed AD would require a one-time

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive No. 2013–0120, 

dated June 4, 2013 (referred to herein 

after as ‘‘MCAI’’), to correct an unsafe 

condition for the specified products. 

The MCAI states: 

A ‘‘chip light illumination’’ event in flight 

on an ARRIEL 1C2 engine was reported to 

Turbomeca. Following the event, which 

resulted from Free Turbine front bearing 

deterioration, the investigation revealed that 

the loss of the Free Turbine (FT) bearing 

module has led to a major disruption in the 

lubrication of the FT module (M04) bearings. 

The root cause of the event has been 

attributed to incorrect bonding of the Free 

Turbine Bearing Plug, accomplished during 

the repair process in an identified Repair 

Center. Consequently, it was possible to 

identify a batch of Modules M04 which are 

potentially affected. 

This condition, if not corrected, could 

lead to a loss of FT bearing lubrication 

resulting in FT module failure, damage 

to the engine, and damage to the 

aircraft. You may obtain further 

information by examining the MCAI in 

the AD docket. 

Relevant Service Information 

Turbomeca S.A. has issued Alert 

Mandatory Service Bulletin No. A292 72 

0838, Version A, dated May 24, 2013. 

The service information describes 

procedures for correcting the unsafe 

condition described in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of France 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 a one-time 

inspection of the FT module (M04) of 

certain Turbomeca S.A. Arriel 1A1, 

1A2, 1B, 1C, 1C1, 1C2, 1D, 1D1, 1E2, 

1K1, 1S, and 1S1 turboshaft engines 

and, if a discrepancy is found, repair of 

the affected module. 

Costs of Compliance 

We estimate that this proposed AD 

affects five engines installed on aircraft 

of U.S. registry. We also estimate that it 

would take about 1 hour per engine to 

comply with the inspection requirement 

in this proposed AD, and about 3 hours 

per engine to repair the module. The 

average labor rate is $85 per hour. 

Required parts cost about $13 per 

product. Based on these figures, we 

estimate the cost of this proposed AD on 

U.S. operators to be $1,765. 

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 proposed 

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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this proposed AD and placed it in the 

AD docket.

Airworthiness Directives; The Boeing

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 767–200, 

–300, –300F, and –400ER airplanes. 

This proposed AD was prompted by 

reports indicating that a standard access 

door was located where an impactresistant access door was required, and 

stencils were missing from some 

impact-resistant access doors. This 

proposed AD would require an 

inspection of the left- and right-hand 

wing fuel tank access doors to 

determine that impact-resistant access 

doors are installed in the correct 

locations, and to replace any door with 

an impact-resistant access door if 

necessary. This proposed AD also 

would require an inspection for stencils 

and index markers on impact-resistant 

access doors, and application of new 

stencils or index markers if necessary. 

This proposed AD would also require 

revising the maintenance program to 

incorporate changes to the airworthiness 

limitations section. We are proposing 

this AD to prevent foreign object 

penetration of the fuel tank, which 

could cause a fuel leak near an ignition 

source (e.g., hot brakes or engine 

exhaust nozzle), consequently leading to 

a fuel-fed fire. 

DATES: We must receive comments on 

this proposed AD by September 26, 

2013. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following
