Airworthiness Directives; Jetstream

Aircraft Limited Jetstream Models 3101

and 3201 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)

Jetstream Models 3101 and 3201

airplanes that have kit JK 2496 and

modification JM 7537 installed. The

proposed action would require

installing magnetic latching relays on

the ignition system. Reports of the autoignition system becoming disabled

when switching from ground power to

the airplane’s internal power prompted

the proposed action. The actions

specified by the proposed AD are

intended to prevent loss of the

airplane’s internal power connection to

the auto-ignition system, which could

cause loss of engine power and possible

loss of the airplane.

DATES: Comments must be received on

or before June 13, 1997.

ADDRESSES: Submit comments in

triplicate to the Federal Aviation

Administration (FAA), Central Region,

Office of the Assistant Chief Counsel,

Rules Docket No. 92–CE–46–AD, Room

1558, 601 E. 12th Street, Kansas City,

Missouri 64106.

Events Leading to the Proposed Action

The Civil Airworthiness Authority

(CAA), which is the airworthiness

authority for the United Kingdom (UK),

recently notified the FAA that an unsafe

condition may exist on certain JAL

Jetstream Models 3101 and 3201

airplanes, serial numbers 693 through

870, that have kit JK 2496 and

modification JM 7537 installed. The

CAA reports that the auto-ignition

arming relays are disarming when the

battery master switch is moved from

ground power (GND) to off (OFF) to

internal power (INT). These conditions,

if not detected, could result in

interruption of power supply to the

auto-ignition system, disabling the restart of the engine, leading to loss of

power.

Related Service Information

JAL has issued Jetstream Service

Bulletin No. 74–JM 7693A, Original

Issue dated May 17, 1990; Revision No.

3 dated January 28, 1993, which

specifies procedures for installing

magnetic latching relays in the

airplane’s ignition system.

The CAA classified this service

bulletin as mandatory in order to ensure

the continued airworthiness of these

airplanes in the United Kingdom.

FAA’s Determination

These airplane models are

manufactured in the United Kingdom

and are 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, including the service

information referenced above; 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 that have kit JK 2496 and

Modification JM 7537 installed,

registered in the United States, the

proposed AD would require installing

magnetically latching relays with wiring

changes. Accomplishment of the

proposed installation would be in

accordance with Jetstream Service

Bulletin No. 74–JM 7693A, Original

Issue dated May 17, 1990; Revision No.

3 dated January 28, 1993.
Federal Register / Vol. 62, No. 71 / Monday, April 14, 1997 / Proposed Rules 18063

Cost Impact

The FAA estimates that 126 airplanes

in the U.S. registry would be affected by

the proposed AD, that it would take

approximately 9 workhours per airplane

to accomplish the proposed action, and

that the average labor rate is

approximately $60 an hour. The

manufacturer is providing the parts at

no charge. Based on these figures, the

total cost impact of the proposed AD on

U.S. operators is estimated to be $68,040

or $540 per airplane.

Jetstream has informed the FAA it has

received approximately 78 orders for the

parts to accomplish the proposed action.

If each set of parts is installed on an

affected airplane the estimated cost to

the owners/operators in the U.S. would

be reduced from $68,040 to $25,920.

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

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 USC 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding a new airworthiness directive

(AD) to read as follows:

Jetstream Aircraft Limited: Docket No. 92–

CE–46–AD.

Applicability: Models 3101 and 3201

airplanes (serial numbers 693 through 870)

that have kit JK 2496 and modification JM

7537 installed, 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 within the next 100

hours time-in-service (TIS) after the effective

date of this AD, unless already accomplished.

Airworthiness Directives; Boeing

Model 747–400 Series Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

adoption of a new airworthiness

directive (AD) that is applicable to

certain Boeing Model 747–400 series

airplanes. This proposal would require

replacing the cam assembly, cam

bellcrank assembly, and thrust reverser

control switch actuator on all four thrust

levers with new components. This

proposal is prompted by a report of an

uncommanded automatic retraction of

the leading edge flaps during takeoff.

The actions specified by the proposed

AD are intended to prevent such

uncommanded automatic retraction,

which could seriously degrade liftoff

and climb capabilities, and result in

near-stall conditions at a critical phase

of the flight.

DATES: Comments must be received by

May 22, 1997.
