Airworthiness Directives; Saab Model

SAAB SF340A and SAAB 340B Series

Airplanes

AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Saab Model SAAB

SF340A and SAAB 340B series

airplanes, that requires repetitive

operational tests of the valve limit

switch of the propeller brake. This

amendment also provides for an

optional terminating action for the

repetitive tests. This amendment is

prompted by a report that when the

propeller brake was not properly

engaged the crew did not receive a

‘‘PROP BRAKE’’ warning due to a faulty

valve limit switch. The actions specified

by this AD are intended to prevent a

valve limit switch from failing to send

input to the warning system; absence of

a ‘‘PROP BRAKE’’ warning could result

in the crew being unaware that the

propeller brake is not properly engaged

and the propeller may turn without

warning.

DATES: Effective March 13, 1996.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of March 13,

1996.

ADDRESSES: The service information

referenced in this AD may be obtained

from SAAB Aircraft AB, SAAB Aircraft

Product Support, S–581.88, Linko ̈ping,

Sweden. This information may be

examined at the Federal Aviation

Administration (FAA), Transport

Airplane Directorate, Rules Docket,

1601 Lind Avenue SW., Renton,

Washington; or at the Office of the

Federal Register, 800 North Capitol

Street NW., suite 700, Washington, DC.

SUPPLEMENTARY INFORMATION: A

proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to

include an airworthiness directive (AD)

that is applicable to certain Saab Model

SAAB SF340A and SAAB 340B series

airplanes was published in the Federal

Register on November 8, 1995 (60 FR

56274). That action proposed to require

repetitive operational tests of the valve

limit switch of the propeller brake. That

action also proposed to provide for the

optional replacement of certain

propeller brake control units with a new

unit, which would constitute

terminating action for the repetitive test

requirements.

Interested persons have been afforded

an opportunity to participate in the

making of this amendment. No

comments were submitted in response

to the proposal or the FAA’s

determination of the cost to the public.

The FAA has determined that air safety

and the public interest require the

adoption of the rule as proposed.

The FAA estimates that 23 airplanes

of U.S. registry will be affected by this

AD, that it will take approximately 1

work hour per airplane to accomplish

the required operational tests, at an

average labor rate of $60 per work hour.

Based on these figures, the cost impact

of the AD on U.S. operators is estimated

to be $1,380, or $60 per airplane, per

test cycle.

The cost impact figure discussed

above is based on assumptions that no

operator has yet accomplished any of

the requirements of this AD action, and

that no operator would accomplish

those actions in the future if this AD

were not adopted.

The regulations adopted herein will

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 final rule does

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)

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 final evaluation has

been prepared for this action and it is

contained in the Rules Docket. A copy

of it may be obtained from the Rules

Docket at the location provided under

the caption ADDRESSES.

Federal Register / Vol. 61, No. 29 / Monday, February 12, 1996 / Rules and Regulations 5285

Adoption of the Amendment

Accordingly, pursuant to the

authority delegated to me by the

Administrator, the Federal Aviation

Administration amends 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 the following new airworthiness

directive:

96–03–08 SAAB Aircraft AB: Amendment

39–9505. Docket 95–NM–79–AD.

Applicability: Model SAAB SF340A series

airplanes, having serial numbers 004 through

159 inclusive; and Model SAAB 340B series

airplanes, having serial numbers 160 through

369 inclusive; on which the propeller brake

system is connected; 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 airplane from the

applicability of this AD.

Compliance: Required as indicated, unless

accomplished previously.

To prevent a valve limit switch from failing

to send input to the ‘‘PROP BRAKE’’ warning

system, which could result in the crew being

unaware that the propeller brake is not

properly engaged and the propeller may turn

without warning, accomplish the following:

(a) Within 100 flight hours after the

effective date of this AD, perform an

operational test of the valve limit switch of

the propeller brake in accordance with Saab

Service Bulletin SAAB 340–61–032, Revision

1, dated June 30, 1995. Repeat the test

thereafter at intervals not to exceed 100 flight

hours.

(b) Replacement of a propeller brake

control unit having part number (P/N)

HP1410100–3, –5, or –7 with a new propeller

brake control unit having P/N HP1410100–

10, and performance of an operational test, in

accordance with Saab Service Bulletin SAAB

340–61–033, dated March 6, 1995,

constitutes terminating action for the

repetitive inspections required by paragraph

(a) of this AD.

(c) As of the effective date of this AD, no

person shall install on any airplane a

propeller brake control unit having P/N

HP1410100–3; or any unit having P/N

HP1410100–5 or –7 unless that unit has been

modified in accordance with Saab Service

Bulletin SAAB 340–61–033, dated March 6,

1995.

(d) An alternative method of compliance or

adjustment of the compliance time that

provides an acceptable level of safety may be

used if approved by the Manager,

Standardization Branch, ANM–113, FAA,

Transport Airplane Directorate. Operators

shall submit their requests through an

appropriate FAA Principal Maintenance

Inspector, who may add comments and then

send it to the Manager, Standardization

Branch, ANM–113.

Note 2: Information concerning the

existence of approved alternative methods of

compliance with this AD, if any, may be

obtained from the Standardization Branch,

ANM–113.

(e) 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.

(f) The tests shall be done in accordance

with Saab Service Bulletin SAAB 340–61–

033, dated March 6, 1995. The replacement

shall be done in accordance with Saab

Service Bulletin SAAB 340–61–032, Revision

1, dated June 30, 1995. This incorporation by

reference was approved by the Director of the

Federal Register in accordance with 5 U.S.C.

552(a) and 1 CFR part 51. Copies may be

obtained from SAAB Aircraft AB, SAAB
