AGENCY: Federal Aviation

Administration, DOT.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to certain Saab Model SAAB

2000 series airplanes, that requires an

inspection to ensure correct installation

of certain self-seal couplings in each

nacelle, and corrective action, if

necessary. This amendment also

requires installation of a new clamp to

the self-seal couplings. This action is

necessary to prevent separation of the

self-seal couplings, which could result

in loss of engine oil pressure and a

flight-crew-commanded engine

shutdown. This action is intended to

address the identified unsafe condition.

DATES: Effective January 2, 2001.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of January 2,

2001.

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

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 2000 series airplanes was

published in the Federal Register on

September 29, 2000 (65 FR 58494). That

action proposed to require an inspection

to ensure correct installation of certain

self-seal couplings in each nacelle, and

corrective action, if necessary. That

action also proposed to require

installation of a new clamp to the selfseal couplings.

Comments

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.

Conclusion

The FAA has determined that air

safety and the public interest require the

adoption of the rule as proposed.

Cost Impact

The FAA estimates that 3 Model

SAAB 2000 series 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

actions, and that the average labor rate

is $60 per work hour. Required parts

will be provided by the vendor at no

charge to operators. Based on these

figures, the cost impact of the required

AD on U.S. operators is estimated to be

$180, or $60 per airplane.

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 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 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.

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

Federal Register / Vol. 65, No. 229 / Tuesday, November 28, 2000 / Rules and Regulations 70781

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

Docket at the location provided under

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 U.S.C. 106(g), 40113, 44701.

§ 39.13 [Amended]

2. Section 39.13 is amended by

adding the following new airworthiness

directive:

000–23–24 Saab Aircraft AB:

Amendment 39–11997. Docket 2000–NM–

221–AD.

Applicability: Model SAAB 2000 series

airplanes, certificated in any category, having

serial numbers –004 through –063 inclusive.

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 (b) 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 as indicated, unless

accomplished previously.

To prevent separation of the self-seal

couplings, which could result in loss of

engine oil pressure and a flight-crewcommanded engine shutdown, accomplish

the following:

Inspection, Installation and Corrective

Actions

(a) Within 3 months after the effective date

of this AD, perform a one-time general visual

inspection to ensure correct installation of

the air-cooled oil cooler (ACOC) self-seal

couplings in each nacelle, and install a new

clamp to the self-seal couplings, in

accordance with Saab Service Bulletin 2000–

79–005, dated May 22, 2000. If any coupling

is installed incorrectly, prior to further flight,

perform the corrective actions specified in

the service bulletin in accordance with the

procedures specified in the service bulletin.

Note 2: For the purposes of this AD, a

general visual inspection is defined as: ‘‘A

visual examination of an interior or exterior

area, installation, or assembly to detect

obvious damage, failure, or irregularity. This

level of inspection is made under normally

available lighting conditions such as

daylight, hangar lighting, flashlight, or droplight, and may require removal or opening of

access panels or doors. Stands, ladders, or

platforms may be required to gain proximity

to the area being checked.’’

Alternative Methods of Compliance

(b) 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,

International Branch, ANM–116, 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, International Branch,

ACTION: Final rule; request for

comments.

SUMMARY: This amendment adopts a

new airworthiness directive (AD) that is

applicable to certain Boeing Model 747–

100, 747–200, 747–300, 747SP, and

747SR series airplanes powered by Pratt

& Whitney JT9D–3 or JT9D–7 series

engines. This action requires

inspections of the vertical chords of the

aft torque bulkhead of the outboard

nacelle struts, and corrective action, if

necessary. This action also provides

optional terminating action for the

inspections. This action is necessary to

detect and correct cracking of the

vertical chords adjacent to the lower

spar fitting, which could result in

separation of the diagonal brace load

path. Continued operation with a

separated diagonal brace load path

increases loads on the upper link,

midspar fitting, and dual side links,

which could result in separation of the

strut and engine from the airplane. This

action is intended to address the

identified unsafe condition.

DATES: Effective December 13, 2000.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director
