Airworthiness Directives; Raytheon

Aircraft Company Beech Model 1900D

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that

applies 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. This

AD requires rewiring the KLN–90B GPS

to eliminate the possibility of

inconsistent NAV ‘‘FLAG’’ displays.

This 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

this 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 an invalid GPS

source without knowing it was invalid.

DATES: This AD becomes effective on

April 9, 2001.

The Director of the Federal Register

approved the incorporation by reference

of certain publications listed in the

regulations as of April 9, 2001.

ADDRESSES: You may get the service

information referenced in this AD from

SUPPLEMENTARY INFORMATION:

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

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.

Has FAA taken any action to this

point? We issued a proposal to amend

part 39 of the Federal Aviation

Regulations (14 CFR part 39) to include

an AD that would apply to certain

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. This

proposal was published in the Federal

Register as a notice of proposed

rulemaking (NPRM) on November 2,

2000 (65 FR 65803). The NPRM

proposed to require rewiring the KLN–

90B GPS to eliminate the possibility of

inconsistent NAV ‘‘FLAG’’ displays.

Was the public invited to comment?

Interested persons were afforded an

opportunity to participate in the making

of this amendment. No comments were

received on the proposed rule or the

FAA’s determination of the cost to the

public.

FAA’s Determination

What is FAA’s final determination on

this issue? After careful review of all

available information related to the

subject presented above, we have

determined that air safety and the

public interest require the adoption of

the rule as proposed except for minor

editorial corrections. We determined

that these minor corrections:

• Will not change the meaning of the

AD; and

• Will not add any additional burden

upon the public than was already

proposed.

Cost Impact

How many airplanes does this AD

impact? We estimate that this AD affects

82 airplanes in the U.S. registry.

What is the cost impact of this AD on

owners/operators of the affected

airplanes? We estimate the following

costs to accomplish the modification:

Labor cost Parts cost Total cost per airplane Total cost on U.S. operators

4 workhours × $60 per hour =

$240.

No parts required for the rewiring $240 per airplane ......................... $240 × 82 = $19,680.

12724 Federal Register / Vol. 66, No. 40 / Wednesday, February 28, 2001 / Rules and Regulations

Note: Warranty credit will be allowed on

all affected airplanes to the extent specified

in the service bulletin.

Regulatory Impact

Does this AD impact various entities?

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.

Does this 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)

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 final

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 ADDRESSES.

SUMMARY: This document publishes in

the Federal Register an amendment

adopting airworthiness directive (AD)

2001–03–52 that was sent previously to

all known U.S. owners and operators of

Bombardier Model CL–600–2B16 (CL–

604) series airplanes by individual

notices. This AD requires revising the

airplane flight manual to provide the

flight crew with revised aft center of

gravity (CG) limits. This action is

prompted by issuance of mandatory

continuing airworthiness information by

a foreign airworthiness authority. The
