AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to all BAe Systems

(Operations) Limited Model BAe 146

and Model Avro 146–RJ series airplanes,

that requires repetitive non-destructive

testing inspections to detect cracking at

the fuselage end of the inner sidestays

of the main landing gear (MLG) by the

anti-rotation pin, and replacement of the

sidestay with a new sidestay, if

necessary. This amendment is necessary

to detect and correct fatigue cracking of

the inner sidestays of the MLG, which

could result in failure of the MLG. This

action is intended to address the

identified unsafe condition.

DATES: Effective March 28, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of March 28,

2001.

ADDRESSES: The service information

referenced in this AD may be obtained

from British Aerospace Regional

Aircraft American Support, 13850

Mclearen Road, Herndon, Virginia

20171. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

1601 Lind Avenue, SW., Renton,

Washington; or at the Office of the

Federal Register, 800 North Capitol

Street, NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to all British

Aerospace Model BAe 146 and Model

Avro 146–RJ series airplanes was

published in the Federal Register on

October 30, 2000 (65 FR 64632). That

action proposed to require repetitive

non-destructive testing inspections to

detect cracking at the fuselage end of the

inner sidestays of the main landing gear

by the anti-rotation pin, and

replacement of the sidestay with a new

sidestay, if necessary.

Manufacturer Name Change

Since the issuance of the proposed

AD, the manufacturer has notified the

FAA that it has changed its name from

British Aerospace to BAe Systems

(Operations) Limited. The final rule has

been changed to reflect the recent

company name change.

Conclusion

After careful review of the available

data, including the comment noted

above, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the change

described previously. The FAA has

determined that this change will neither

increase the economic burden on any

operator nor increase the scope of the

AD.

Cost Impact

The FAA estimates that 60 Model BAe

146 and Model Avro 146–RJ series

airplanes, of U.S. registry will be

affected by this AD. It will take

approximately 1 work hour per airplane

to accomplish the required inspection,

at an average labor rate of $60 per work

hour. Based on these figures, the cost

impact of the 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 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 adopted herein will

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 final rule does not

have federalism implications under

Executive Order 13132.

For the reasons discussed above, I

certify that this action (1) is not a

‘‘significant regulatory action’’ under

Executive Order 12866; (2) is not a

‘‘significant rule’’ under 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. A final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Model Avro 146–RJ70A, 146–RJ85A, and

146–RJ100A series airplanes; certificated in

any category.

Note 1: This AD applies to each airplane

identified in the preceding applicability

provision, regardless of whether it has been

modified, altered, or repaired in the area

subject to the requirements of this AD. For

airplanes that have been modified, altered, or

repaired so that the performance of the

requirements of this AD is affected, the

owner/operator must request approval for an

alternative method of compliance in

accordance with paragraph (c) of this AD.

The request should include an assessment of

the effect of the modification, alteration, or

repair on the unsafe condition addressed by

this AD; and, if the unsafe condition has not

been eliminated, the request should include

specific proposed actions to address it.

Compliance: Required as indicated, unless

accomplished previously.

To detect and correct fatigue cracking of

the inner sidestays of the main landing gear

(MLG), which could result in failure of the

MLG, accomplish the following:

Inspection

(a) Prior to the accumulation of 8,000 total

flight cycles on the MLG sidestays, or within

500 flight cycles after the effective date of

this AD, whichever occurs later: Perform a

non-destructive testing (NDT) inspection to

detect cracking at the fuselage end of the

inner sidestays of the MLG by the antirotation pin, in accordance with MessierDowty Service Bulletin 146–32–148,

including Appendix A, dated April 17, 2000.

Repeat the inspection thereafter at intervals

not to exceed 4,000 flight cycles.

Replacement

(b) If any cracking is found during any

inspection required by paragraph (a) of this

AD, prior to further flight, replace the

sidestay with a new sidestay in accordance

with BAE Systems Service Bulletin SB.32–

157, dated June 2, 2000.

Alternative Methods of Compliance

(c) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager,

International Branch, ANM–116, FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, International Branch,

ANM–116.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the International Branch,

ANM–116.
