Discussion

The Direction Ge ́ne ́rale de l’Aviation

Civile (DGAC), which is the

airworthiness authority for France,

notified the FAA that an unsafe

condition may exist on certain

Aerospatiale Model ATR42–200, –300,

and –320 series airplanes. The DGAC

advises that the flightcrew of a Model

ATR42–320 series airplane switched off

the emergency battery following a

charge fault, and subsequently

experienced a partial loss of direct

current (DC) power during descent

when they selected the continuous

relight position on the starting rotary

switch. This type of failure could occur

on an airplane if the continuous relight

position of the engine start selector is

not wired to the ground. In this case, the

DC power of the emergency and standby

buses is transferred from DC bus 1 (the

main network) to the failed emergency

battery, resulting in the loss of some

electrical loads. This condition, if not

corrected, could result in the display of

erroneous information to the flightcrew.

Similar Models

The continuous relight position of the

engine start selector is similar on

ATR42–200, –300, and –320 series

airplanes; therefore, these airplanes are

all subject to the identified unsafe

condition.

Explanation of Relevant Service

Information

The manufacturer has issued Avions

de Transport Regional Service Bulletin

ATR42–80–0001, Revision 2, dated

November 15, 2000. The service bulletin

describes procedures for modifying the

starting rotary switch by installing

wiring connecting the ground to the

continuous relight position.

Accomplishment of the actions

specified in the service bulletin is

intended to adequately address the

identified unsafe condition. The DGAC

classified this service bulletin as

mandatory and issued French

airworthiness directive 2000–454–

081(B), dated November 15, 2000, to

ensure the continued airworthiness of

these airplanes in France.

FAA’s Conclusions

These airplane models are

manufactured in France and are type

certificated for operation in the United

States under the provisions of section

21.29 of the Federal Aviation

Regulations (14 CFR 21.29) and the

applicable bilateral airworthiness

agreement. Pursuant to this bilateral

airworthiness agreement, the DGAC has

kept the FAA informed of the situation

described above. The FAA has

examined the findings of the DGAC,

reviewed all available information, and

determined that AD action is necessary

for products of this type design that are

certificated for operation in the United

States.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

accomplishment of the actions specified

in the service bulletin described

previously.

Cost Impact

The FAA estimates that 60 airplanes

of U.S. registry would be affected by this

proposed AD, that it would take

approximately 4 work hours per

airplane to accomplish the proposed

actions, and that the average labor rate

is $60 per work hour. Required parts

would be provided by the manufacturer

at no cost to operators. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$14,400, or $240 per airplane.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the proposed requirements of this AD

action, and that no operator would

accomplish those actions in the future if

this proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

The regulations proposed herein

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. Therefore,

it is determined that this proposal

would not have federalism implications

under Executive Order 13132.

For the reasons discussed above, I

certify that 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) if

20770 Federal Register / Vol. 66, No. 80 / Wednesday, April 25, 2001 / Proposed Rules

promulgated, 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. A copy of the draft

regulatory evaluation prepared for this

action is contained in the Rules Docket.

A copy of it may be obtained by

contacting the Rules Docket at the

location provided under the caption
