14 CFR Part 39
[Docket No. 2002-NM-259-AD]
RIN 2120-AA64
Airworthiness Directives; Saab Model SAAB 2000 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 2000
series airplanes. This proposal would require an inspection of roll and
pitch disconnect handles for spring forces outside limits, and
adjustment of the spring force of the handles, if necessary. This
action is necessary to prevent the roll and pitch disconnect handles
from being difficult to operate, which could result in an increase in
pilot workload and subsequent reduced controllability of the airplane.
This action is intended to address the identified unsafe condition.
DATES: Comments must be received by April 5, 2004.
ADDRESSES: Submit comments in triplicate to the Federal Aviation
Administration (FAA), Transport Airplane Directorate, ANM-114,
Attention: Rules Docket No. 2002-NM-259-AD, 1601 Lind Avenue, SW.,
Renton, Washington 98055-4056. Comments may be inspected at this
location between 9 a.m. and 3 p.m., Monday through Friday, except
Federal holidays. Comments may be submitted via fax to (425) 227-1232.
Comments may also be sent via the Internet using the following address:
9-anm-nprmcomment@faa.gov. Comments sent via fax or the Internet must
contain ``Docket No. 2002-NM-259-AD'' in the subject line and need not
be submitted in triplicate. Comments sent via the Internet as attached
electronic files must be formatted in Microsoft Word 97 for Windows or

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 2000 series airplanes. The LFV advises that there have
been two instances during C-checks in which the roll and pitch
disconnect handles were difficult to operate. An abnormal force is
needed to pull the handles. This condition, if not corrected, could
result in an increase in pilot workload and subsequent reduced
controllability of the airplane.
Explanation of Relevant Service Information
Saab has issued Service Bulletin 2000-27-047, dated August 30,
2002, which describes procedures for inspection of the roll and pitch
disconnect handles for difficult operation, and adjustment of the
handles, if necessary. Accomplishment of the actions specified in the
service bulletin is intended to adequately address the identified
unsafe condition. The LFV classified this service bulletin as mandatory
and issued Swedish airworthiness directive 1-177, dated August 30,
2002, in order to assure the continued airworthiness of these airplanes
in Sweden.
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 actions specified in the service bulletin described previously.
Cost Impact
The FAA estimates that 3 airplanes of U.S. registry would be
affected by this proposed AD, that it would take approximately 4 work
hours per airplane to accomplish the proposed inspection, and that the
average labor rate is $65 per work hour. Based on these figures, the
cost impact of the proposed AD on U.S. operators is estimated to be
$780, or $260 per airplane.
The cost impact figure discussed above is 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 location provided under the caption ADDRESSES.

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. 106(g), 40113, 44701.
[[Page 10372]]
Sec. 39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
SAAB Aircraft AB: Docket 2002-NM-259-AD.
Applicability: Model SAAB 2000 series airplanes, serial numbers
-004 through -063 inclusive; certificated in any category.
Compliance: Required as indicated, unless accomplished
previously.
To prevent the roll and pitch disconnect handles from being
difficult to operate, which could result in an increase in pilot
workload and subsequent reduced controllability of the airplane,
accomplish the following:
Inspection and Modification
(a) Within 400 flight hours after the effective date of this AD,
perform an inspection of the roll and pitch disconnect handles for
difficult operation, in accordance with the Accomplishment
Instructions of Saab Service Bulletin 2000-27-047, dated August 30,
2002. If the force required to move any disconnect handle is found
to be outside the limits specified in the service bulletin, before
further flight, adjust the spring force of the handle in accordance
with the Accomplishment Instructions of the service bulletin.
Parts Installation
(b) As of the effective date of this AD, no person may install
on any airplane a roll disconnect handle, part number 7339056-503,
or pitch disconnect handle, part number 7339056-504, unless it has
been inspected and the spring force has been adjusted as applicable,
per paragraph (a) of this AD.
Alternative Methods of Compliance
(c) In accordance with 14 CFR 39.19, the Manager, International
Branch, ANM-116, FAA, is authorized to approve alternative methods
of compliance (AMOCs) for this AD.
Note 1: The subject of this AD is addressed in Swedish
airworthiness directive 1-177, dated August 30, 2002.
Issued in Renton, Washington, on February 25, 2004.
