14 CFR Part 39
[Docket No. 2003-CE-28-AD]
RIN 2120-AA64
Airworthiness Directives; Cessna Aircraft Company Models 172R,
172S, 182S, 182T, T182T, 206H, and T206H 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 Cessna Aircraft Company (Cessna)
Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that
are equipped with a Honeywell KAP 140 autopilot computer system
installed on the center instrument control panel near the throttle.
This proposed AD would require you to install an update to the
operating software of the KAP 140 autopilot computer system, change the
unit's part number, and change the software modification identification
tab. This proposed AD is the result of reports of inadvertent and
undetected engagement of the autopilot system. The actions specified by
this proposed AD are intended to prevent unintentionally engaging the
KAP 140 autopilot computer system, which could cause the pilot to take
inappropriate actions.

Discussion
What Events Have Caused This Proposed AD?
We have received reports of an unsafe condition on certain Cessna
Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that
are equipped with a Honeywell KAP 140 autopilot computer system.
The KAP 140 autopilot computer system is located on the lower
portion of the center instrument control panel near the throttle on
these Cessna airplanes. Because of this location on the instrument
control panel of the affected Cessna airplanes, the Autopilot Engage
(AP) button could unintentionally be depressed when the pilot pushes
the throttle knob forward. The pilot could also unintentionally engage
the autopilot system by inadvertently bumping the Heading (HDG) button,
Altitude (ALT) mode-select button, or Autopilot Engage (AP) button on
the KAP 140 computer. Unless intentionally engaged, the pilot does not
know that the autopilot system is engaged.
The Honeywell KAP 140 autopilot computer system is also installed
in the New Piper, Inc. Model PA-28-181 airplanes. This proposed AD
would not affect these airplanes because of the location of the
equipment. The equipment is installed on the center instrument panel
near the throttle on the affected airplanes, but is installed in the
upper half of the instrument control
[[Page 44498]]
panel on the Piper airplanes. The unsafe condition only exists on the
Cessna airplanes.
Honeywell has updated the operating software for the KAP 140
autopilot computer system, which will now only allow the AP button on
the instrument control panel to engage the autopilot system. This
update also adds two voice messages if auto trim operation is detected,
lengthens the amount of time that the autopilot button must be
depressed in order for it to engage, and changes how the flight control
display shows that the AP has been engaged.
What Are the Consequences if the Condition Is Not Corrected?
If not corrected, inadvertent and undetected engagement of the
autopilot system could cause the pilot to take inappropriate actions.
Is There Service Information That Applies to This Subject?
Cessna has issued Service Bulletin SB02-22-01, dated November 25,
2002.
Honeywell has issued Service Bulletin No: KC 140-M1, dated August
2002; and Installation Bulletin No: 491, dated August 2002.
What Are the Provisions of This Service Information?
Cessna Service Bulletin SB02-22-02, dated November 25, 2002,
specifies installing an update to the autopilot computer system
operating software by accomplishing the actions in Honeywell Service
Bulletin No: KC 140-M1, dated August 2002.
Honeywell Service Bulletin No: KC 140-M1, dated August 2002,
includes procedures for:
--Installing an update to the autopilot computer system operating
software;
--Changing the unit part number;
--Placing an M tag on the unit serial number tag; and
--Changing the unit's software modification tag.
Honeywell Installation Bulletin No: 491, dated August 2002,
describes the operational changes the software update makes to the KC
140 autopilot computer system.
The FAA's Determination and an Explanation of the Provisions of this
Proposed AD
What Has FAA Decided?
After examining the circumstances and reviewing all available
information related to the incidents described above, we have
determined that:
--The unsafe condition referenced in this document exists or could
develop on other Cessna Models 172R, 172S, 182S, 182T, T182T, 206H, and
T206H of the same type design;
--The actions specified in the previously-referenced service
information should be accomplished on the affected airplanes; and
--AD action should be taken in order to correct this unsafe condition.
What Would This Proposed AD Require?
This proposed AD would require you to update to the operating
software of the KAP 140 autopilot computer system; change the unit's
part number; and change the software modification identification tab.
How Does the Revision to 14 CFR Part 39 Affect This Proposed AD?
On July 10, 2002, FAA published a new version of 14 CFR part 39 (67
FR 47997, July 22, 2002), which governs FAA's AD system. This
regulation now includes material that relates to special flight
permits, alternative methods of compliance, and altered products. This
material previously was included in each individual AD. Since this
material is included in 14 CFR part 39, we will not include it in
future AD actions.
Cost Impact
How Many Airplanes Would This Proposed AD Impact?
We estimate that this proposed AD affects 3,681 airplanes in the
U.S. registry.
What Would Be the Cost Impact of This Proposed AD on Owners/Operators
of the Affected Airplanes?
We estimate the following costs to accomplish this proposed
modification:
------------------------------------------------------------------------
Total cost
Labor cost Parts cost per
airplane
------------------------------------------------------------------------
7 workhours x $65 per hour = $455.. Not applicable........ $455.
------------------------------------------------------------------------
Not all Cessna Models 172R, 172S, 182S, 182T, T182T, 206H, and
T206H airplanes on the U.S. registry have a KAP 140 autopilot computer
system installed.
Honeywell will provide warranty credit for labor and parts to the
extent noted under WARRANTY INFORMATION in each specified in Honeywell
Service Bulletin No: KC 140-M1, dated August 2002.
Regulatory Impact
Would This Proposed AD Impact Various Entities?
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 proposed rule would not have federalism
implications under Executive Order 13132.
Would This Proposed AD Involve a Significant Rule or Regulatory Action?
For the reasons discussed above, I certify that this proposed
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 contacting the Rules Docket at
the location provided under the caption ADDRESSES.
