would be affected by this proposed AD,

that it would take approximately 16

work hours per airplane to accomplish

the proposed actions, and that the

average labor rate is $60 per work hour.

Required parts would cost

approximately $250 per airplane. Based

on these figures, the cost impact of the

proposed AD on U.S. operators is

estimated to be $12,100, or $1,210 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 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

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

Discussion

The Civil Aviation Authority (CAA),

which is the airworthiness authority for

the United Kingdom, notified the FAA

that an unsafe condition may exist on

all British Aerospace Model BAe 146

and Model Avro 146-RJ series airplanes.

The CAA advises that, during increased

load fatigue testing, a crack has been

found at the fuselage end on the inner

sidestays of the main landing gear

(MLG) by the anti-rotation pin. Such

fatigue cracking, if not detected and

corrected, could result in failure of the

MLG.

Explanation of Relevant Service

Information

The manufacturer has issued British

Aerospace Service Bulletin SB.32–157,

dated June 2, 2000. The British

Aerospace service bulletin references

Messier-Dowty Service Bulletin 146–

32–148, including Appendix A, dated

April 17, 2000, as the appropriate

source of service information for

accomplishment of repetitive nondestructive testing (NDT) inspections to

detect cracking at the fuselage end of the

inner sidestays of the MLG by the antirotation pin. The British Aerospace

service bulletin recommends that

cracked sidestays be replaced with new

sidestays prior to further flight.

Accomplishment of the actions

specified in the Messier-Dowty service

bulletin is intended to adequately

address the identified unsafe condition.

The CAA classified the British

Aerospace service bulletin as mandatory

and issued British airworthiness

directive 001–06–2000 in order to

assure the continued airworthiness of

these airplanes in the United Kingdom.

FAA’s Conclusions

These airplane models are

manufactured in the United Kingdom

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 CAA has

kept the FAA informed of the situation

described above. The FAA has

examined the findings of the CAA,

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 inspections

specified in the Messier-Dowty service

bulletin described previously. The

proposed AD also would require

replacement of any cracked sidestay

with a new sidestay.

Cost Impact

The FAA estimates that 60 Model BAe

146–100A, –200A, and –300A series

airplanes, and Model Avro 146RJ70A,

146RJ85A, and 146–RJ100A series

airplanes, of U.S. registry would be

affected by this proposed AD. It would

take approximately 1 work hour per

airplane to accomplish the proposed

inspection, at an average labor rate of

$60 per work hour. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$3,600, or $60 per airplane, per

inspection cycle.

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 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

64634 Federal Register / Vol. 65, No. 210 / Monday, October 30, 2000 / Proposed Rules

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

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.
