electric trim manual override loads after

the new motor is installed, and making

any necessary adjustments.

Accomplishment of the proposed

modification would be in accordance

with the service bulletins previously

referenced.

Cost Impact

The FAA estimates that 25 airplanes

in the U.S. registry would be affected by

the proposed AD, that it would take

approximately 6 workhours per airplane

to accomplish the proposed action, and

that the average labor rate is

approximately $60 an hour. The

manufacturer will provide parts at no

cost to the owner/operator. Based on

these figures, the total cost impact of the

proposed AD on U.S. operators is

estimated to be $9,000, or $360 per

airplane.

Regulatory Impact

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 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) 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 has been placed in the Rules

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to

certain Lockheed Model L–1011–385

series airplanes. This proposal would

require the replacement of the flap

position indicator with an improved

flap position indicator. This proposal is

prompted by a report indicating that an

airplane landed at an excessive sink rate

and sustained substantial structural

damage when the leading edge slats

failed to extend for landing and the

flightcrew failed to increase airspeed in

response, due to inadequate

annunciation of the slat failure. The

actions specified by the proposed AD

are intended to prevent such inadequate

annunciation, which could result in the

flightcrew being unaware when the

leading edge slats fail to extend

properly; such failure could result in

reduced stall margins, and consequent

reduced controllability of the airplane.

Discussion

The FAA has received a report

indicating that the flightcrew of a

Lockheed Model L–1011–385 series

airplane failed to notice that the leading

edge slats did not extend during

approach for landing. As a result, the

approach speed was not adjusted to

compensate for this abnormal

configuration. The airplane landed at an

excessive sink rate and sustained

substantial structural damage. The cause

has been attributed to the existing

design of the flap and slat display

system, which does not provide

adequate annunciation to the flightcrew

when the leading edge slats have failed

to extend. The existing flap position

indicator of the flap and slat display

system does not provide a conspicuous

warning should the leading edge slats

fail to extend or retract properly during

flap operation. This condition, if not

corrected, could result in the flightcrew

being unaware when the leading edge

slats fail to extend properly; such failure

could result in reduced stall margins,

and consequent reduced controllability

of the airplane.

Explanation of Relevant Service

Information

The FAA has reviewed and approved

Lockheed Service Bulletin 093–27–128,

Revision 2, dated December 1, 1997,

which describes procedures for

replacement of the flap position

indicator with an improved flap

position indicator. Accomplishment of

the actions specified in the service

bulletin is intended to adequately

address the identified unsafe condition.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other products of this same

type design, the proposed AD would

require accomplishment of the action

specified in the service bulletin

described previously.

Cost Impact

There are approximately 164

airplanes of the affected design in the

worldwide fleet. The FAA estimates that

89 airplanes of U.S. registry would be

affected by this proposed AD, that it

would take approximately 2 work hours

per airplane to accomplish the proposed

replacement, and that the average labor

rate is $60 per work hour. Required

parts would cost approximately $25,000

per airplane. Based on these figures, the

cost impact of the replacement proposed

by this AD on U.S. operators is

estimated to be $2,235,680, or $25,120

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.

Regulatory Impact

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

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

Lockheed: Docket 98–NM–36–AD.

Applicability: Model L–1011–385–1, –14,

and –15 series airplanes, as listed in

Lockheed Service Bulletin 093–27–128,

Revision 2, dated December 1, 1997;

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 prevent inadequate annunciation to the

flightcrew of leading edge slat failures, which

could result in reduced stall margins, and

consequent reduced controllability of the

airplane, accomplish the following:

(a) Within 18 months after the effective

date of this AD, replace the flap position

indicator with a new, improved flap position

indicator, in accordance with Lockheed

Service Bulletin 093–27–128, Revision 2,

dated December 1, 1997.

Note 2: Replacement of the flap position

indicator accomplished prior to the effective

date of this AD, in accordance with Lockheed

Service Bulletin 093–27–128, dated

November 8, 1976, or Revision 1, dated

January 17, 1977, is considered acceptable for

compliance with paragraph (a) of this AD.

(b) As of the effective date of this AD, no

person shall install a flap position indicator,

part number 672563–111 or 672563–115, on

any airplane.

(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, Atlanta

Aircraft Certification Office (ACO), FAA,

Small 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, Atlanta ACO.

Note 3: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Atlanta ACO.

(d) Special flight permits may be issued in

accordance with sections 21.197 and 21.199

of the Federal Aviation Regulations (14 CFR

21.197 and 21.199) to operate the airplane to

a location where the requirements of this AD

can be accomplished.
