Airworthiness Directives; Saab Model

SAAB SF340A 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 Saab Model SAAB SF340A

series airplanes. This proposal would

require replacement of the air

recirculation fans in the flight

compartment and the passenger

compartment. These fans may be

replaced with upgraded fans with new

brushes having insulation on the brush

leads or they may be replaced with

modified fans, having new, brushless

motors. This action is prompted by

mandatory continuing airworthiness

information by a foreign civil

airworthiness authority. This action is

necessary to prevent incidents of smoke

or a burning smell in the cabin during

flight, caused by incorrect brush

insulation in the motors of the air

recirculation fans in the flight

compartment and the passenger

compartment. This action is intended to

address the identified unsafe condition.

Discussion

The Luftfartsverket (LFV), which is

the airworthiness authority for Sweden,

notified the FAA that an unsafe

condition may exist on certain Saab

Model SAAB SF340A series airplanes.

The LFV advises that incorrect brush

insulation, used in the motors of the air

recirculation fans for the flight

compartment and the passenger

compartment, has produced smoke or a

burning smell in the cabin on a number

of occasions. Such incorrect brush

insulation could result in additional

incidents of smoke or a burning smell in

the cabin during flight.

Explanation of Relevant Service

Information

Saab has issued Service Bulletin 340–

21–039, dated August 23, 2000, which

describes procedures for removing the

air recirculation fans and replacing

them with upgraded air recirculation

fans with new brushes having insulation

on the brush leads. The LFV classified

34590 Federal Register / Vol. 66, No. 126 / Friday, June 29, 2001 / Proposed Rules

this service bulletin as mandatory and

issued Swedish airworthiness directive

1–160, dated August 24, 2000, in order

to assure the continued airworthiness of

these airplanes in Sweden.

In addition, Saab has issued Service

Bulletin 340–21–018, Revision 02, dated

June 21, 2000, which describes

procedures for removing the air

recirculation fans, modifying them by

removing the motors and installing new,

brushless motors. The LFV has not

classified this service bulletin as

mandatory but indicates that it may be

performed to satisfy the requirements of

Swedish airworthiness directive 1–160,

dated August 24, 2000.

FAA’s Conclusions

This airplane model is manufactured

in Sweden 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 LFV has kept the FAA informed of

the situation described above. The FAA

has examined the findings of the LFV,

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.

Explanation of Requirements of

Proposed Rule

Since an unsafe condition has been

identified that is likely to exist or

develop on other airplanes of the same

type design registered in the United

States, the proposed AD would require

accomplishment of the action specified

in either of the two service bulletins

described previously.

Cost Impact

There are approximately 35 Model

SAAB SF340A series airplanes of U.S.

registry. The FAA estimates that it

would take approximately 4 work hours

per airplane to accomplish the proposed

replacement of the two air recirculation

fans having part number (P/N) C209–

690C with two upgraded air

recirculation fans having P/N C209–

690D, and that the average labor rate is

$60 per work hour. Based on these

figures, the cost impact of the proposed

replacement is estimated to be $240 per

airplane.

The FAA estimates that it would take

approximately 2 work hours per

airplane to accomplish the proposed

optional modification of the two air

recirculation fans by installing new,

brushless motors, and that the average

labor rate is $60 per work hour. The cost

of a kit containing two brushless motors

is estimated to be $38,000. Based on

these figures, the cost impact of the

proposed modification is estimated to

be $38,120 per airplane.

The cost impact figures discussed

above are 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 proposed AD were not adopted. The

cost impact figures discussed in AD

rulemaking actions represent only the

time necessary to perform the specific

actions actually required by the AD.

These figures typically do not include

incidental costs, such as the time

required to gain access and close up,

planning time, or time necessitated by

other administrative actions.

Regulatory Impact

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 proposal

would not have federalism implications

under Executive Order 13132.

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

contacting the Rules Docket at the

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Notice of proposed rulemaking

(NPRM).

SUMMARY: This document proposes the

supersedure of an existing airworthiness

directive (AD); applicable to certain

Boeing Model 737–600, –700, and –800

series airplanes; that currently requires

repetitive inspections of certain elevator

hinge plates, and corrective action, if

necessary. That AD also provides for an

optional replacement of the elevator

hinge plates with new, improved hinge

plates, which would end the repetitive

inspections. This action proposes to

require accomplishment of the

previously optional replacement of the

elevator hinge plates with new,

improved hinge plates, as terminating

action for the repetitive inspections.

This action is necessary to prevent

fatigue cracking of the elevator hinge

plates, which could lead to the loss of

the attachment of the elevator to the

horizontal stabilizer, and consequent

reduced controllability of the airplane.

This action is intended to address the

identified unsafe condition.

Discussion

On March 15, 2001, the FAA issued

AD 2001–06–08, amendment 39–12155

(66 FR 16116, March 23, 2001);

applicable to certain Boeing Model 737–

600, –700, and –800 series airplanes; to

require repetitive inspections of certain

elevator hinge plates, and corrective

action, if necessary. That AD also

provides for an optional replacement of

the elevator hinge plates with new,

improved hinge plates, which would

end the repetitive inspections. That

action was prompted by a report that—

during flight testing of Boeing Model

737–600, –700, and –800 series

airplanes—the elevator hinge plates at

elevator hinges 3, 4, 5, 6, 7, and 8

experienced higher-than-expected loads

due to buffeting by the spoiler. The

requirements of that AD are intended to

detect and correct fatigue cracking of the

elevator hinge plates, which could lead

to the loss of the attachment of the

elevator to the horizontal stabilizer, and

consequent reduced controllability of

the airplane.

Actions Since Issuance of Previous Rule

In the preamble to AD 2001–06–08,

the FAA indicated that the actions

required by that AD were considered

‘‘interim action’’ and that further

rulemaking action was being considered

to require the replacement of the

elevator hinge plates with new parts,

which was provided as optional in AD

2001–06–08, and which would

terminate the repetitive inspections

currently required by that AD. The FAA

now has determined that further

rulemaking action is indeed necessary,
