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: 

There have been failures of the harness 

assembly (power feeder wires) connecting the 

Air-Driven Generator (ADG) to the aeroplane 

electrical system, in the area close to the 

ADG cannon plug. Several electrical wires 

were found cut as a combined result of 

corrosion and bending stress from the 

harness mounting to the ADG. 

The ADG electrical wires are insulated 

with a silver-plating for corrosion protection. 

It has been determined that the silver-plating 

of wire strands in the area of tight bend is 

highly susceptible to breakdown. The plating 

layer may crack as a result of mechanical 

stress, and consequently lead to the onset of 

corrosion on all, or a majority, of the wire 

strands. 

In the event of a damaged harness 

assembly, the ADG may not be able to 

provide emergency electrical power to the 

aeroplane. * * * 

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 September 20, 

2010.

Discussion 

Transport Canada Civil Aviation 

(TCCA), which is the aviation authority 

for Canada, has issued Canadian 

Airworthiness Directive CF–2009–47, 

dated December 14, 2009 (referred to 

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

unsafe condition for the specified 

products. The MCAI states: 

There have been failures of the harness 

assembly (power feeder wires) connecting the 

Air-Driven Generator (ADG) to the aeroplane 

electrical system, in the area close to the 

ADG cannon plug. Several electrical wires 

were found cut as a combined result of 

corrosion and bending stress from the 

harness mounting to the ADG. 

The ADG electrical wires are insulated 

with a silver-plating for corrosion protection. 

It has been determined that the silver-plating 

of wire strands in the area of tight bend is 

highly susceptible to breakdown. The plating 

layer may crack as a result of mechanical 

stress, and consequently lead to the onset of 

corrosion on all, or a majority, of the wire 

strands. 

In the event of a damaged harness 

assembly, the ADG may not be able to 

provide emergency electrical power to the 

aeroplane. This directive is issued to correct 

the identified unsafe condition by requiring 

[the modification of the ADG, which 

includes] the replacement of the harness 

assembly with tin-plated electrical wires, [the 

replacement of the backshell,] and the reorientation of the ADG cannon plug to reduce 

bending stress. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Bombardier, Inc. issued Service 

Bulletin 601R–24–128, Revision A, 

dated November 27, 2009; and Service 

Bulletin 670BA–24–027, dated 

September 17, 2009. 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 920 products of U.S. 

registry. We also estimate that it would 

take about 8 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 $1,881 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 

$2,356,120, or $2,561 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 


wwoods2 on DSK1DXX6B1PROD with PROPOSALS
Federal Register / Vol. 75, No. 150 / Thursday, August 5, 2010 / Proposed Rules 47251 

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.
