Discussion

The Civil Aviation Authority (CAA),

which is the airworthiness authority for

the United Kingdom, recently notified

the FAA that an unsafe condition may

exist on certain British Aerospace
Federal Register / Vol. 60, No. 96 / Thursday, May 18, 1995 / Proposed Rules 26703

Model BAe 146–100A and –200A

airplanes. The CAA advises that there is

a possibility that, if the airplane’s lift

spoilers fail to deploy on landing, the

flight crew may not be made aware of

this situation. There currently is no

method or warning installed in the

flight deck to alert the flight crew that

the lift spoilers have failed to deploy on

landing. If the lift spoilers fail to deploy

when the airplane lands, and the

flightcrew is unaware of it, the airplane

could overrun the end of the runway.

British Aerospace has issued Service

Bulletin SB.27–70–00913A&B, Revision

7, dated March 21, 1994, which

describes procedures for modifying the

glareshield and certain electrical

equipment of the airplane. The

modification involves installing an

amber warning light in the glareshield

that will illuminate if the lift spoilers

fail to deploy on landing. The

modification also includes installing

new wires, a new printed circuit board

(PCB), PCB connector and polarizing

key in the PCB rack, and a new relay in

circuit breaker panel number two. The

modification also entails performing a

test of the glareshield warning light and

an inhibit and fault monitoring

operational test of the lift spoiler.

Accomplishment of this modification

will provide the flight crew with a

warning if the lift spoilers fail to deploy

on landing. The CAA classified this

service bulletin as mandatory in order to

assure the continued airworthiness of

these airplanes in the United Kingdom.

This airplane model is manufactured

in the United Kingdom and is 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.

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

modification of the glareshield and

certain electrical equipment of the

airplane. The actions would be required

to be accomplished in accordance with

the service bulletin described

previously.

As a result of recent communications

with the Air Transport Association

(ATA) of America, the FAA has learned

that, in general, some operators may

misunderstand the legal effect of AD’s

on airplanes that are identified in the

applicability provision of the AD, but

that have been altered or repaired in the

area addressed by the AD. The FAA

points out that all airplanes identified in

the applicability provision of an AD are

legally subject to the AD. If an airplane

has been altered or repaired in the

affected area in such a way as to affect

compliance with the AD, the owner or

operator is required to obtain FAA

approval for an alternative method of

compliance with the AD, in accordance

with the paragraph of each AD that

provides for such approvals. A note has

been included in this notice to clarify

this long-standing requirement.

The FAA estimates that 38 airplanes

of U.S. registry would be affected by this

proposed AD, that it would take

approximately 21 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 $6,000 per

airplane. Based on these figures, the

total cost impact of the proposed AD on

U.S. operators is estimated to be

$275,880, or $7,260 per airplane.

The total 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 regulations proposed herein

would not have substantial direct effects

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,

in accordance with Executive Order

12612, it is determined that this

proposal would not have sufficient

federalism implications to warrant the

preparation of a Federalism Assessment.

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

contacting the Rules Docket at the

location provided under the caption

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 use the authority

provided in paragraph (b) to request approval

from the FAA. This approval may address

either no action, if the current configuration

eliminates the unsafe condition; or different

actions necessary to address the unsafe

condition described in this AD. Such a

request should include an assessment of the

effect of the changed configuration on the

unsafe condition addressed by this AD. In no

case does the presence of any modification,

alteration, or repair remove any airplane from

the applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

SUPPLEMENTARY INFORMATION:

I. Background on the Wyoming AMLR

Plan

On February 14, 1983, the Secretary of

the Interior approved the Wyoming

plan. Information pertaining to the

general background, revisions, and

amendments to the initial plan

submission, as well as the Secretary’s

findings, the disposition of comments,

and the approval of the Wyoming plan

can be found in the February 14, 1983,

Federal Register (48 FR 6536).

Subsequent actions concerning

Wyoming’s plan and plan amendments

can be found at 30 CFR 950.30 and

950.35.

II. Proposed Amendment

By letter dated April 21, 1995

(administrative record No. WY–AML–

018–8), Wyoming submitted a proposed

amendment to its AMLR plan pursuant

to SMCRA. Wyoming submitted the

proposed amendment at its own

initiative to allow the implementation of

two initiatives established under

Omnibus Budget Reconciliation Act of

1990 (Pub. L. 101–508). Wyoming

proposes to revise its AMLR plan at

Wyoming Statute (W.S.) 35–11–1206 (a)

and (b) to (1) authorize liens against

privately-owned land adversely affected

by past coal or mineral mining

practices, (2) limit the amount of any

lien to the cost of reclamation work or

to the amount determined by the

appraisal to be the increase in the fair

market value of the land as a result of

the restoration, reclamation, abatement,

control or prevention of the adverse

effects of past coal or noncoal mining

practices, whichever is less, (3) allow

the landowner to petition the district

court for the district in which most of

the land is located within 60 days of the

filing of the lien to determine the

increase in the fair market value of the

land, and (4) provide that the amount

reported to be the increase in the value

of the land, but not exceeding the cost

of the reclamation work, shall constitute

the amount of the lien. Wyoming also

proposes that the revisions to W.S. 35–

11–1206 (a) and (b) shall take effect on

July 1, 1995.

Wyoming proposes to create W.S. 35–

11–1209 to (1) prohibit the issuance of

contracts under the AMLR program to

any construction contractor or

professional services contractor if any

surface coal mining and reclamation

operation owned or controlled by the

contractor or any person who owns or

controls the contractor has failed to pay

its coal reclamation fees or has other

types of violations, (2) provide that the

term ‘‘ownership or controlling interest’’

means as defined in the Federal

regulations at 30 CFR 773.5, and (3)

provide that the Wyoming AMLR

program will implement the provisions

of this section for all new contracts

awarded after April 1, 1995.

III. Public Comment Procedures

In accordance with the provisions of

30 CFR 884.15(a) and 884.14(a), OSM is

seeking comments on whether the

proposed amendment satisfies the

applicable plan approval criteria of 30

CFR 884.14. If the amendment is

deemed adequate, it will become part of

the Wyoming plan.

1. Written Comments

Written comments should be specific,

pertain only to the issues proposed in

this rulemaking, and include

explanations in support of the

commenter’s recommendations.
