30156 Federal Register / Vol. 63, No. 106 /Wednesday, June 3, 1998 / Proposed Rules

corrected, could affect the pilot’s ability

to control the airplane.

The affected computers are

Honeywell IC–600 integrated avionics

computers, which may be installed in,

but not limited to, Learjet Model 45 and

EMBRAER Model EMB–145 series

airplanes.

Explanation of Relevant Service

Information

The FAA has reviewed and approved

Honeywell Service Bulletin 7017000–

22–43, dated March 24, 1998, which

describes procedures for modification of

the integrated avionics computers. This

modification involves replacing

programmable array logic devices U6,

U32, and U33 with new modified parts;

adding two resistors; replacing resistor

R7 with a new value; adding two

capacitors; and adding bus wires.

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 actions

specified in the service bulletin

described previously.

Cost Impact

There are approximately 38 airplanes

of the affected design in the worldwide

fleet. The FAA estimates that 20

airplanes of U.S. registry would be

affected by this proposed AD. It would

take approximately 2 work hours per

airplane to accomplish the proposed

modification at an average labor rate of

$60 per work hour. Required parts

would be supplied by the manufacturer

at no cost to operators. Based on these

figures, the cost impact of the proposed

AD on U.S. operators is estimated to be

$2,400, or $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

The Proposed Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration proposes to amend 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. Section 39.13 is amended by

adding the following new airworthiness

directive:

Honeywell. Docket 98–NM–142–AD.

Applicability: Honeywell IC–600 integrated

avionics computers having part numbers

7017000–82201, –82202, –82203, –82204,

–82351, –82352, –82401, –82402, –82403,

–83351, –83352, –83401, –83402, and

–83403, as installed in, but not limited to,

Learjet Model 45 and EMBRAER Model

EMB–145 series airplanes.

Note 1: This AD applies to Honeywell IC–

600 integrated avionics computers having

part numbers 7017000–82201, –82202,

–82203, –82204, –82351, –82352, –82401,

–82402, –82403, –83351, –83352, –83401,

–83402, and –83403, as installed in any

airplane, regardless of whether the airplane

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 a ‘‘random reset’’ condition of

the electronic flight instrument system,

which could affect the pilot’s ability to

control the airplane, accomplish the

following:

(a) Within 6 months after the effective date

of this AD, modify the IC–600 integrated

avionics computer, in accordance with

Honeywell Service Bulletin 7017000–22–43,

dated March 24, 1998.

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

person shall install a Honeywell IC–600

integrated avionics computer having part

number 7017000–82201, –82202, –82203,

–82204, –82351, –82352, –82401, –82402,

–82403, –83351, –83352, –83401, –83402, or

–83403 on any airplane, unless it has been

modified in accordance with Honeywell

Service Bulletin 7017000–22–43, dated

March 24, 1998.

(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, Los

Angeles Aircraft Certification Office (ACO),

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, Los Angeles ACO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Los Angeles 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.

The Proposal

The FAA is considering an

amendment to 14 CFR part 71 to remove

Class D airspace and Class E airspace at

Willoughby, OH. The required criteria

for Class D airspace is no longer being

met, as the air traffic control tower for

Willoughby, Lost Nation Airport, OH,

has been decommissioned. The removal

of the Class D airspace will also cause

the removal of the Class E airspace

extensions to the Class D airspace. Class

D airspace designations are published in

paragraph 5000, and Class E airspace

designations for airspace areas

designated as an extension to a Class D

surface area are published in paragraph

6004, of FAA Order 7400.9E dated

September 10, 1997, and effective

September 16, 1997, which is

incorporated by reference in 14 CFR

71.1. The Class D and Class E airspace

designations listed in this document

would be removed subsequently from

the Order.

The FAA has determined that this

proposed regulation only involves an

established body of technical

regulations for which frequent and

routine amendments are necessary to

keep them operationally current.

Therefore this, proposed regulation—(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)

does not warrant preparation of a

Regulatory Evaluation as the anticipated

impact is so minimal. Since this is a

routine matter that will only affect air

traffic procedures and air navigation, it

is that this proposed rule will not have

a significant economic impact on a

substantial number of small entities

under the criteria of the Regulatory

Flexibility Act.
