Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes to

adopt a new airworthiness directive

(AD) that would apply to certain

Raytheon Aircraft Company (Raytheon)

Beech Model 1900D airplanes that are

equipped with a KLN–90B Global

Positioning System (GPS) incorporated

in accordance with AlliedSignal

Supplemental Type Certificate (STC)

SA00245WI–D. The proposed AD would

require rewiring the KLN–90B GPS to

eliminate the possibility of inconsistent

NAV ‘‘FLAG’’ displays. The proposed

AD is the result of an instance where the

copilot’s NAV ‘‘FLAG’’ display was

based on the pilot’s NAV source

validity. The actions specified by the

proposed AD are intended to assure that

the copilot’s NAV ‘‘FLAG’’ displays are

based on the copilot’s selected NAV

source. Inconsistent NAV ‘‘FLAG’’

displays could cause the copilot to make

decisions based on using an invalid GPS

source without knowing it was invalid.

DATES: The Federal Aviation

Administration (FAA) must receive any

comments on this rule on or before

December 29, 2000.

ADDRESSES: Submit comments in

triplicate to FAA, Central Region, Office

of the Regional Counsel, Attention:

Rules Docket No. 2000–CE–10–AD, 901

Locust, Room 506, Kansas City,

Missouri 64106. Comments may be

inspected at this location between 8

a.m. and 4 p.m., Monday through

Friday, holidays excepted.

Service information that applies to the

proposed AD may be obtained from the

Raytheon Aircraft Company, PO Box 85,

SUPPLEMENTARY INFORMATION:

Comments Invited

How do I comment on the proposed

AD? The FAA invites comments on this

proposed rule. You may submit

whatever written data, views, or

arguments you choose. You need to

include the rule’s docket number and

submit your comments in triplicate to

the address specified under the caption

ADDRESSES. The FAA will consider all

comments received on or before the

closing date. We may amend the

proposed rule in light of comments

received. Factual information that

supports your ideas and suggestions is

extremely helpful in evaluating the

effectiveness of the proposed AD action

and determining whether we need to

take additional rulemaking action.

Are there any specific portions of the

proposed AD I should pay attention to?

The FAA specifically invites comments

on the overall regulatory, economic,

environmental, and energy aspects of

the proposed rule that might suggest a

need to modify the rule. You may

examine all comments we receive before

and after the closing date of the rule in

the Rules Docket. We will file a report

in the Rules Docket that summarizes

each FAA contact with the public that

concerns the substantive parts of the

proposed AD.

We are re-examining the writing style

we currently use in regulatory

documents, in response to the

Presidential memorandum of June 1,

1998. That memorandum requires

federal agencies to communicate more

clearly with the public. We are

interested in your comments on whether

the style of this document is clearer, and

any other suggestions you might have to

improve the clarity of FAA

communications that affect you. You

can get more information about the

Presidential memorandum and the plain

language initiative at http://

www.plainlanguage.gov.

How can I be sure FAA receives my

comment? If you want us to

acknowledge the receipt of your

comments, you must include a selfaddressed, stamped postcard. On the

postcard, write ‘‘Comments to Docket

No. 2000–CE–10–AD.’’ We will date

you.

Discussion

What events have caused this AD?

The FAA has received a report of

inconsistent NAV ‘‘FLAG’’ displays on

the KLN–90B Global Positioning System

(GPS) that was installed on a Raytheon

Model Beech 1900D airplane. This

system is installed in accordance with

65804 Federal Register / Vol. 65, No. 213 / Thursday, November 2, 2000 / Proposed Rules

AlliedSignal Supplemental Type

Certificate (STC) SA00245WI–D, and

could be installed on Raytheon Beech

Model 1900D airplanes, serial numbers

UE–156 through UE–299.

In this situation, the copilot had the

KLN–90B GPS selected as the NAV

source and the pilot did not have a valid

NAV source selected. This caused the

flight director command bar to

disappear from the copilot’s electronic

attitude director indicator (EADI), and

the copilot received an inconsistent

NAV ‘‘FLAG’’.

What are the consequences if the

condition is not corrected? Inconsistent

NAV ‘‘FLAG’’ displays could cause the

copilot to make decisions based on an

invalid GPS source without knowing it

was invalid.

Relevant Service Information

Is there service information that

applies to this subject? Raytheon has

issued Mandatory Service Bulletin SB

34–3222, Issued: January, 2000.

What are the provisions of this service

bulletin? The service bulletin includes

procedures for rewiring the KLN–90B

GPS to eliminate the possibility of

inconsistent NAV ‘‘FLAG’’ displays.

The FAA’s Determination and an

Explanation of the Provisions of the

Proposed AD

What has FAA decided? After

examining the circumstances and

reviewing all available information

related to the incidents described above,

we have determined that:

• The unsafe condition referenced in

this document exists or could develop

on other Raytheon Beech Model 1900D

airplanes of the same type design;

• The actions specified in the

previously-referenced service

information should be accomplished on

the affected airplanes; and

• AD action should be taken in order

to correct this unsafe condition.

What would the proposed AD require?

This proposed AD would require

rewiring the KLN–90B GPS to eliminate

the possibility of inconsistent NAV

‘‘FLAG’’ displays.

Cost Impact

How many airplanes would the

proposed AD impact? We estimate that

the proposed AD affects 82 airplanes in

the U.S. registry.

What would be the cost impact of the

proposed AD on owners/operators of the

affected airplanes? We estimate the

following costs to accomplish the

proposed modification:

Labor cost Parts cost Total cost per

airplane

Total cost on

U.S. airplane

operators

4 workhours × $60 per hour = $240 ............................ No parts required for the rewiring ................................ $240 per

airplane

$19,680

Note: Warranty credit will be allowed on all affected airplanes to the extent specified in the service bulletin.

Regulatory Impact

Would this proposed AD impact

various entities? The regulations

proposed herein would 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 proposed rule

would not have federalism implications

under Executive Order 13132.

Would this proposed AD involve a

significant rule or regulatory action? 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 Docket. A copy of it may

be obtained by contacting the Rules

Docket at the location provided under

the caption ADDRESSES.

Discussion

What events have caused this AD?

The FAA has received a report of an

incident on a Raytheon Model C99

airplane where a cracked main landing

gear (MLG) hydraulic actuator end cap

resulted in nose landing gear (NLG)

collapse during landing. The cracked
