AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: We propose to adopt a new 

airworthiness directive (AD) for the 

products listed above. This proposed 

AD results from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

During pre-delivery inspections and test 

flights, several short circuit events were 

reported, one of which resulted in smoke in 

the cockpit. There were no in-service 

incidents. 

Investigations have identified three 

conditions affecting the wiring of Circuit 

Breaker Panels * * * and Junction Boxes 

* * *, which would lead to short circuiting: 

* * * * * 

If not corrected, these conditions could result 

in arcing, damage to adjacent structure, 

smoke in the cockpit, or loss of system 

redundancies. 

* * * * * 

The proposed AD would require actions 

that are intended to address the unsafe 

condition described in the MCAI. 

DATES: We must receive comments on 

this proposed AD by December 12, 

2011.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the airworthiness 

authority for Canada, has issued 

Canadian Airworthiness Directive CF– 

2010–25, dated August 3, 2010 (referred 

to after this as ‘‘the MCAI’’), to correct 


jlentini on DSK4TPTVN1PROD with PROPOSALS
66204 Federal Register / Vol. 76, No. 207 / Wednesday, October 26, 2011 / Proposed Rules 

an unsafe condition for the specified 

products. The MCAI states: 

During pre-delivery inspections and test 

flights, several short circuit events were 

reported, one of which resulted in smoke in 

the cockpit. There were no in-service 

incidents. 

Investigations have identified three 

conditions affecting the wiring of Circuit 

Breaker Panels 1, 2, 3 and 4 (CBP–1, CBP– 

2, CBP–3, and CBP–4) and Junction Boxes 17 

and 18 (JB17 and JB18), which would lead to 

short circuiting: 

1. In CBP–1, there may be low clearance 

between specific bus bars and the circuit 

breaker panel structure. 

2. Some nickel-plated terminal lugs, size 

number 22–20 with a green insulating sleeve, 

may not have been manufactured to 

applicable standards. These terminal lugs 

may have been installed in CBP–1, CBP–2, 

CBP–3, CBP–4, JB17 and JB18. This 

manufacturing defect affects the mechanical 

hold of the wire in the crimped lug barrel. 

3. In JB17, JB18 and the above-mentioned 

CBPs, foreign object debris (FOD) may be 

found. 

If not corrected, these conditions could 

result in arcing, damage to adjacent structure, 

smoke in the cockpit, or loss of system 

redundancies. 

This TCCA directive is issued to mandate 

the replacement or relocation of the specific 

CBP–1 bus bars, the [detailed] inspection, 

and rework if necessary, of any loose or 

improperly crimped lugs in CBP–1, CBP–2, 

CBP–3, CBP–4, JB17 and JB18, and to ensure 

there is no FOD in the affected areas [via a 

general visual inspection for FOD, and 

removal if necessary]. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier has issued Service 

Bulletin 605–24–002, dated December 

07, 2009, and Service Bulletin 605–24– 

004, dated January 18, 2010. The actions 

described in this service information are 

intended to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This Proposed AD 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to our 

bilateral agreement with the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are proposing this 

AD because we evaluated all pertinent 

information and determined an unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have proposed 

different actions in this AD from those 

in the MCAI in order to follow FAA 

policies. Any such differences are 

highlighted in a NOTE within the 

proposed AD. 

Costs of Compliance 

Based on the service information, we 

estimate that this proposed AD would 

affect about 69 products of U.S. registry. 

We also estimate that it would take 

about 6 work-hours per product to 

comply with the basic requirements of 

this proposed AD. The average labor 

rate is $85 per work-hour. Required 

parts would cost about $347 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these costs. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of the 

proposed AD on U.S. operators to be 

$59,133, or $857 per product. 

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); and 

3. 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.

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: This document proposes 

adopting a new airworthiness directive 

(AD) for the Sikorsky Aircraft 

Corporation (Sikorsky) Model S–76A 

helicopters. This proposal would 

require modifying the electric rotor 

brake (ERB). Thereafter, the AD would 

also require inserting changes to the 

‘‘Normal Procedures’’ and ‘‘Emergency 

Procedures’’ sections of the Rotorcraft 

Flight Manual (RFM), which revises the 

information of the basic RFM when the 

ERB is installed. This proposal is 

prompted by a reported incident of a 

fire occurring in an ERB installed on a 

Model S–76A helicopter. The actions 

specified by this proposed AD are 

intended to prevent overheating of the 

ERB assembly, ignition of the ERB 

hydraulic fluid, a fire in the main 

gearbox area, and subsequent loss of 

control of the helicopter. 

DATES: Comments must be received on 

or before December 27, 2011.
