14 CFR Part 39 

[Docket No. FAA–2013–0831; Directorate 

Identifier 2013–NM–125–AD] 

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Airplanes 

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 737–100, 

–200, –200C, –300, –400, and –500 

series airplanes. This proposed AD was 

prompted by reports of chaffing, arcing, 

and burning damage to the control cabin 

overhead wiring and ducting with 

smoke and fire caused by metal clamps 

installed on certain hoses. This 

proposed AD would require inspecting 

for the presence of metal clamps, 

replacing metal clamps installed on the 

hoses to the air conditioning 

temperature sensor, gasper air outlet, 

and diffuser on the left side of the 

control cabin with plastic tie straps, and 

inspecting for and repairing damaged 

wire bundles. We are proposing this AD 

to prevent damage to wire bundles, 

which could cause electrical arcing that 

could result in a fire or smoke in the 

control cabin of the airplane. 

DATES: We must receive comments on 

this proposed AD by November 12, 

2013. 

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– 

2013–0831; Directorate Identifier 2013– 

NM–125–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 have received numerous reports of 

incorrectly installed metal clamps on 

the hoses to the air conditioning 

temperature sensor, gasper air outlet, 

and diffuser on the left side of the 

control cabin at station (STA) 259.5, 

many of which have led to wire bundle 

chaffing and in several cases led to 

arcing and burning damage to the 

control cabin overhead wiring and 

ducting with smoke and fire. Incorrectly 

installed metal clamps, if not corrected, 

could cause wire bundle damage and 

electrical arcing that could result in a 

fire or smoke in the control cabin of the 

airplane. 

Relevant Service Information 

We reviewed Boeing Service Bulletin 

737–21–1186, dated April 17, 2012. For 

information on the procedures, see this 

service information at http:// 

www.regulations.gov by searching for 

Docket No. FAA–2013–0831. 

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 the same 

type design. 

Proposed AD Requirements 

This proposed AD would require 

accomplishing the actions specified in 

the service information identified 

previously, except as discussed under 

‘‘Differences Between the Proposed AD 

and the Service Information.’’ 

Differences Between the Proposed AD 

and the Service Information 

While Boeing Service Bulletin 737– 

21–1186, dated April 17, 2012 does not 

specify a compliance time, this 

proposed AD would require doing the 

inspection and replacement within 60 

months after the effective date of this 

AD. 

While Boeing Service Bulletin 737– 

21–1186, dated April 17, 2012, requires 

doing a general visual inspection for 

correct part number and correct 

installation of metal clamps, this 

proposed AD would require doing a 

general visual inspection to determine if 

any metal clamp is installed on the 

hoses to the air conditioning 

temperature sensor, gasper air outlet, 

and diffuser on the left side of the 

control cabin at STA 259.5. 

While Boeing Service Bulletin 737– 

21–1186, dated April 17, 2012, allows 

the continued use of metal clamps, this 

proposed AD would require operators to 

replace each metal clamp with a plastic 

tie strap. 

While Boeing Service Bulletin 737– 

21–1186, dated April 17, 2012, specifies 

to contact Boeing for instructions for 

certain airplanes, this proposed AD 

would require that those actions be 

done in one of the following ways: 

• In accordance with a method that 

we approve; or 

• Using data that meets the 

certification basis of the airplane, and 

that has been approved by the Boeing 

Commercial Airplanes Organization

Designation Authorization (ODA) whom 

we have authorized to make those 

findings. 

Costs of Compliance 

We estimate that this proposed AD 

affects 426 airplanes of U.S. registry. 

We estimate the following costs to 

comply with this proposed AD: 

ESTIMATED COSTS

Action Labor cost Parts cost Cost per product Cost on U.S. 

operators 

Inspection and Replacement.2 work-hours × $85 per hour = $170 per replacement.$0 $170 per replacement ..... $72,420 

We have received no definitive data 

that would enable us to provide cost 

estimates for the on-condition actions 

specified in this proposed AD. We have 

no way of determining the number of 

products that may need these actions. 

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, 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.

Airworthiness Directives; Eurocopter 

France Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for 

Eurocopter France (Eurocopter) Model 

AS332C, AS332L, AS332L1, AS332L2, 

and SA330J helicopters. This proposed 

AD would prohibit use of the hydraulic 

hoist in helicopters equipped with 

certain parts and configurations until a 

hoist beam lower fitting protector is 

installed. This proposed AD is 

prompted by a report that the hoist 

cable jammed during a rescue at sea. 

The proposed actions are intended to 

prevent the hoist cable from jamming 

and subsequent cable failure, which 

could result in injury and damage to the 

helicopter. 

DATES: We must receive comments on 

this proposed AD by November 25, 

2013.

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2009– 

0271R1, dated July 8, 2011, to correct an 

unsafe condition for Eurocopter Model 

AS332C, AS332C1, AS332L1, AS332L2, 

and SA330J helicopters with certain 

hoist beams installed. EASA advises 

that during a hoisting operation, a 

hydraulic hoist cable jammed against 

the base of the supporting strut of a dual 

hoist tray installation. According to 

EASA, the load was transferred to the 

back-up electrical hoist and safely 

brought on board. However, the 

jamming of the hydraulic hoist cable 

against the strut damaged the back-up 

electrical hoist power supply harness, 

which is routed through the area, 

resulting in a short circuit that fused 

and ruptured the cable. EASA reports 

that this condition, if not corrected, 

could lead to further incidents of hoist 

cable jamming and subsequent cable 

failure, which could result in personal 

injuries and damage to the helicopter. 

FAA’s Determination 

These helicopters have been approved 

by the aviation authority of France and
