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

Jetstream Aircraft Limited (JAL) Models

3101 and 3201 airplanes. The proposed

action would require modifying the

central annunciator panel test button

circuit. A report of diode failure in this

circuit and subsequent inadvertent

engine shutdown on one of the affected

airplanes prompted the proposed action.

The actions specified in the proposed

AD are intended to prevent failure of a

diode in the central annunciator panel

test button circuit, which, if not

detected and corrected, could result in

inadvertent engine shutdown while in

flight if the central annunciator panel

test button is pressed.

Discussion

The Civil Aviation Authority (CAA),

which is the airworthiness authority for

the United Kingdom, has notified the

FAA that an unsafe condition may exist

on JAL Jetstream Models 3101 and 3201

airplanes. The CAA reports that a diode

failed in the central annunciator panel

test button circuit on one of the affected

airplanes. This led to inadvertent engine

failure of one of the engines when the

airplane operator pressed the central

annunciator panel test button.

JAL has issued Jetstream Alert Service

Bulletin (ASB) 80–A–JA 911045,

Revision 1, dated November 1, 1991,

which specifies procedures for

modifying the central annunciator panel

test button circuit on Jetstream Models

3101 and 3201 airplanes. The

modification (Amendment JA 911045)

consists of removing diodes from the

engine stop circuit and configuring a

minor wire change.

In order to assure the continued

airworthiness of these airplanes in the

United Kingdom, the CAA classified

Jetstream ASB 80–A–JA 911045,

Revision 1, dated November 1, 1991, as

mandatory. The CAA classifying a

service document as mandatory is the

same for airplanes registered in the

United Kingdom as the FAA issuing an

AD for airplanes registered in the

United States.

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 in other JAL Jetstream Models

3101 and 3201 airplanes of the same

type design, the proposed AD would

require modifying the central

annunciator panel test button circuit by

removing diodes from the engine stop

circuit and configuring a minor wiring

change. The proposed actions would be

accomplished in accordance with

Jetstream ASB 80–A–JA 911045,

Revision 1, dated November 1, 1991.

The FAA estimates that 260 airplanes

in the U.S. registry would be affected by

the proposed AD, that it would take
Federal Register / Vol. 60, No. 69 / Tuesday, April 11, 1995 / Proposed Rules 18377

approximately 2 workhours per airplane

to accomplish the proposed

modification, and that the average labor

rate is approximately $60 an hour. JAL

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

$31,200. This figure is based on the

assumption that no affected owner/

operator has incorporated the proposed

modification.

JAL has informed the FAA that 2

modification kits have been distributed

to affected airplane owners/operators.

Assuming that each of these

modification kits has been incorporated

on an affected airplane, then the

proposed cost impact upon U.S.

operators would be reduced $240 (2

workhours × $60 per hour × 2 airplanes)

from $31,200 to $30,960. The FAA also

believes that numerous owners/

operators of the affected airplanes have

accomplished the modification using

22AWA cable and terminal tags instead

of obtaining parts from the

manufacturer, as is provided for in the

proposed AD. This would further

reduce the cost impact of the proposed

AD upon U.S. operators of the affected

airplanes. The FAA has no way of

determining how many airplanes have

accomplished the proposed

modification utilizing the 22AWA cable

and terminal tags alternative.

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

Docket. A copy of it may be obtained by

contacting the Rules Docket at the

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. App. 1354(a), 1421

and 1423; 49 U.S.C. 106(g); and 14 CFR

11.89.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding a new AD to read as follows:

Jetstream Aircraft Limited: Docket No. 91–

CE–85–AD.

Applicability: Jetstream Model 3101

airplanes, all serial numbers, and Jetstream

Model 3201 airplanes, serial numbers 790

through 950, 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 use the authority

provided in paragraph (d) of this AD 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 aircraft from the

applicability of this AD.

Compliance: Required within the next 200

hours time-in-service after the effective date

of this AD, unless already accomplished.

To prevent failure of a diode in the central

annunciator panel test button circuit, which,

if not detected and corrected, could result in

inadvertent engine shutdown while in flight

if the central annunciator panel test button is

pressed, accomplish the following:

(a) Modify the central annunciator panel

test button circuit (Amendment JA 911045)

by removing diodes from the engine stop

circuit and configuring a minor wiring

change in accordance with PART 2 of the

ACCOMPLISHMENT INSTRUCTIONS

section of Jetstream Alert Service Bulletin

80–A–JA 911045, Revision 1, dated

November 1, 1991.

(b) As noted in Jetstream Alert Service

Bulletin 80–A–JA 911045, Revision 1, dated

November 1, 1991, terminals may be linked

using 22 AWA cable and terminal tags,

provided the following is accomplished:

(1) For airplanes without roof panel plug

breaks, identify the cables as WQ69 and

WQ70.

(2) For airplanes with roof panel plug

breaks, identify the cables as WQ71 and

WQ72.

(c) 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.

(d) An alternative method of compliance or

adjustment of the compliance time that

provides an equivalent level of safety may be

approved by the Manager, Brussels Aircraft

Certification Office (ACO), Europe, Africa,

Middle East office, FAA, c/o American

Embassy, B–1000 Brussels, Belgium. The

request should be forwarded through an

appropriate FAA Maintenance Inspector,

who may add comments and then send it to

the Manager, Brussels ACO.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Brussels ACO.
