Adoption of the Amendment

Accordingly, under the authority

delegated to me by the Administrator,

the Federal Aviation Administration

amends part 39 of the Federal Aviation

Regulations (14 CFR part 39) as follows:

PART 39—AIRWORTHINESS

DIRECTIVES

1. The authority citation for part 39

continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. FAA amends § 39.13 by adding a

new AD to read as follows:

2001–01–03 British Aerospace:

Amendment 39–12073; Docket No.

2000–CE–57–AD.

(a) What airplanes are affected by this AD?

This AD affects Models HP137 Mk1,

Jetstream Series 200, and Jetstream Models

3101 and 3201 airplanes, all serial numbers,

certificated in any category.

(b) Who must comply with this AD?

Anyone who wishes to operate any of the

above airplanes must comply with this AD.

(c) What problem does this AD address?

The actions specified by this AD are intended

to prevent failure of the nose landing gear

steering actuator because of problems with

the current design piston rod. Continued

operation with the current design piston rod

could result in loss of nose wheel steering

and possible loss of control of the airplane

during takeoff, landing, and taxi operations.

(d) What actions must I accomplish to

address this problem? To address this

problem, you must accomplish the following:

Action Compliance time Procedures

(1) Remove the nose landing gear steering actuator and install one that incorporates a

modified piston rod.

Within the next 3,000 landings after May 5,

2000 (the issue date of the applicable service bulletin) or within the next 90 days after

February 17, 2001 (the effective date of this

AD), whichever occurs later, unless already

accomplished. If the number of landings is

unknown, you may use hours time-in-service (TIS) by multiplying the number of hours

TIS by 0.75. In this carfe, 3,000 landings

would be equal to 4,000 hours TIS (4,000

hours TIS ×.75=3,000 landings).

In accordance with the procedures in APPH

Ltd. Service Bulletin 32–73, dated April

2000, as referenced in British Aerospace

Jetstream Manadatory Service Bulletin 32–

JA000342, Issued: May 5, 2000.

(2) You may not install, on any affected airplane, a nose landing gear unit that does not

incorporate a modified steering actuator piston rod, as required by paragraph (d)(1) of

this AD.

As of February 17, 2001 (the effective date of

this AD).

Not Applicable.

(e) Can I comply with this AD in any other

way? You may use an alternative method of

compliance or adjust the compliance time if:

(1) Your alternative method of compliance

provides an equivalent level of safety; and

(2) The Manager, Small Airplane

Directorate, approves your alternative.

Submit your request through an FAA

Principal Maintenance Inspector, who may

add comments and then send it to the

Manager, Small Airplane Directorate.

Note 1: This AD applies to each airplane

identified in paragraph (a) of this AD,

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 (e)

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 you have not

eliminated the unsafe condition, specific

actions you propose to address it.

(f) Where can I get information about any

already-approved alternative methods of

compliance? Contact Mr. Doug Rudolph,

Aerospace Engineer, FAA, Small Airplane

Directorate, 901 Locust, Room 301, Kansas

City, Missouri 64106; telephone: (816) 329–

FAA can issue a special flight permit under

sections 21.197 and 21.199 of the Federal

Aviation Regulations (14 CFR 21.197 and

21.199) to operate your airplane to a location

where you can accomplish the requirements

of this AD.

(h) Are any service bulletins incorporated

into this AD by reference? Actions required

by this AD must be done in accordance with

APPH Ltd. Service Bulletin 32–73, dated

April 2000, as referenced in British

Aerospace Jetstream Mandatory Service

Bulletin 32–JA000342, Issued: May 5, 2000.

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to all BAE Systems

(Operations) Limited (Jetstream) Model

4101 airplanes, that requires inspection

4648 Federal Register / Vol. 66, No. 12 / Thursday, January 18, 2001 / Rules and Regulations

for cracking of the mounting brackets of

the hydraulic hand pump at the frame

attachment flanges, replacement of any

cracked bracket with a new bracket,

replacement of all bolts and nuts with

new bolts and nuts, and installation of

a particular ‘‘D’’ packer. The actions

specified by this AD are intended to

prevent failure of these brackets, which

could result in inability to extend the

landing gear in an emergency situation

where the main hydraulic system is lost.

This action is intended to address the

identified unsafe condition.

DATES: Effective February 22, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of February

22, 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

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 (Jetstream) Model 4101

airplanes was published in the Federal

Register on October 30, 2000 (65 FR

64629). That action proposed to require

inspection for cracking of the mounting

brackets of the hydraulic hand pump at

the frame attachment flanges,

replacement of any cracked bracket with

a new bracket, replacement of all bolts

and nuts with new bolts and nuts, and

installation of a particular ‘‘D’’ packer.

Manufacturer Name Change

The manufacturer name in the final

rule has been changed from British

Aerospace to BAE Systems (Operations)

Limited to reflect the recent company

name change.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

Conclusion

After careful review of the available

data, 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 59 airplanes

of U.S. registry will be affected by this

AD, that it will take approximately 4

work hours per airplane to accomplish

the required actions, and that the

average labor rate is $60 per work hour.

Based on these figures, the cost impact

of the AD on U.S. operators is estimated

to be $14,160, or $240 per airplane.

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.

ACTION: Final rule.

SUMMARY: This amendment supersedes

an existing airworthiness directive (AD),

applicable to certain Airbus Industrie

Model A300, A300–600, and A310

series airplanes; equipped with Dowty

ram air turbines (RAT). That AD

currently requires repetitive deployment

tests of the RAT and checks of the

adjustment of the locking rod. This

amendment also requires modification

of the RAT, which terminates the

repetitive tests and checks. This

amendment is prompted by issuance of

mandatory continuing airworthiness

information by a foreign civil

airworthiness authority. The actions

specified by this AD are intended to

ensure the availability of the RAT in

case of need.

DATES: Effective February 22, 2001.

The incorporation by reference of

certain publications, as listed in the

regulations, is approved by the Director

of the Federal Register as of February

22, 2001.

The incorporation by reference of

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39)

by superseding AD 94–04–05,

amendment 39–8823 (59 FR 7208,

February 15, 1994), which is applicable

to certain Airbus Industrie Model A300,

A300–600, and A310 series airplanes,

was published as a supplemental notice

of proposed rulemaking (NPRM) in the

Federal Register on August 23, 2000 (65

FR 51254). The action proposed to

continue to require repetitive

deployment tests of the ram air turbine

(RAT) and checks of the adjustment of

the locking rod. The action also

proposed to require modification of the

RAT, which would terminate the

repetitive tests and checks, and to

expand the applicability of the existing

AD.

Airplane Model Designation Change

Since the issuance of the

supplemental NPRM, the FAA has

determined that it is necessary to revise

the manner in which it specifies the

model designation for Airbus Model

A300 and A300–600 series airplanes to

reflect the designations that appear on

the type certificate data sheet (TCDS).

This final rule has been revised

accordingly.

Comments

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the supplemental NPRM or the FAA’s

determination of the cost to the public.

Conclusion

After careful review of the available

data, the FAA has determined that air

safety and the public interest require the

adoption of the rule with the change

previously described. 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

There are approximately 126

airplanes of U.S. registry that will be

affected by this AD.

The repetitive tests and checks that

are required by AD 94–04–05, and

retained in this AD, take approximately

2 work hours per airplane to

accomplish, at an average labor rate of

$60 per work hour. Based on these

figures, the cost impact of this

requirement on U.S. operators is
