Federal Aviation Administration (FAA), DOT.
Notice of proposed rulemaking (NPRM).
The FAA proposes to supersede Airworthiness Directive (AD) 2003-24-13, which applies to certain Cessna Aircraft Company (Cessna) Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a certain Honeywell KAP 140 autopilot computer system installed on the center instrument control panel near the throttle. AD 2003-24-13 currently requires you to install an update to the operating software of certain 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 the FAA inadvertently omitting four affected Honeywell KAP 140 autopilot computer system part numbers and an affected airplane serial number from the applicability section of AD 2003-24-13. This proposed AD retains the actions required in AD 2003-24-13, corrects the applicability section, and incorporates a revised installation bulletin issued by Honeywell.
We must receive any comments on this proposed AD by May 10, 2004.
Use one of the following to submit comments on this proposed AD:
- By mail: FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2004-CE-03-AD, 901 Locust, Room 506, Kansas City, Missouri 64106.

We will consider all comments received by the closing date and may amend this proposed AD in light of those comments and contacts.
Has FAA Taken Any Action to This Point?
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 caused us to issue AD 2003-24-13, Amendment 39-13382 (68 FR 67789, December 3, 2003).
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 panel on the Piper airplanes. The unsafe condition only exists on certain Cessna airplanes.
Honeywell has updated the operating software for the KAP 140 autopilot computer system, which will now allow only 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.
AD 2003-24-13 currently requires the following on certain Cessna Aircraft Company Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H airplanes that are equipped with a Honeywell KAP 140 autopilot computer system, part number (P/N) 065-00176-2602 , P/N 065-00176-5402, or P/N 065-00176-7702 installed on the center instrument control panel near the throttle:
—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.
What Has Happened Since AD 2003-24-13 to Initiate This Proposed Action?
We inadvertently omitted four affected Honeywell KAP 140 autopilot computer systems and an affected serial number for Model 182T airplanes from the applicability section. Honeywell revised Installation Bulletin No. 491 to the Rev. 3 level (dated April 2003). We will incorporate this bulletin into this proposed AD.
What Is the Potential Impact If FAA Took No Action?
If not corrected, inadvertent and undetected engagement of the autopilot system could cause the pilot to take inappropriate actions.
FAA's Determination and Requirements of this Proposed AD
What Has FAA Decided?
We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other products of this same type design. Therefore, we are proposing AD action.
What Would This Proposed AD Require?
This proposed AD would retain the actions required in AD 2003-24-13, would add four additional affected Honeywell KAP 140 autopilot computer system part numbers and an affected airplane serial number to the applicability section, and would incorporate a revised Honeywell installation bulletin.
How Does the Revision to 14 CFR Part 39 Affect This Proposed AD?
On July 10, 2002, we 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 altered products, special flight permits, and alternative methods of compliance. 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.
Costs of Compliance
How Many Airplanes Does This AD Impact?
We estimate that this AD affects 3,681 airplanes in the U.S. registry.
What is the Cost Impact of This AD on Owners/Operators of the Affected Airplanes?
We estimate the following costs to accomplish the modification: Start Printed Page 11348
|Labor cost||Parts cost||Total cost per airplane||Total cost on U.S. operators|
|7 workhours × $65 per hour = $455||Not applicable||$455||$455 × 3,681 = $1,674,855|
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 Honeywell Service Bulletin No: KC 140-M1, dated August 2002, and Honeywell Installation Bulletin No. 491, Rev. 3, dated April 2003.
What Is the Difference Between the Cost Impact of This Proposed AD and the Cost Impact of AD 2003-24-13?
The difference is the addition of four KC 140 autopilot systems and one airplane serial number to the applicability section of this proposed AD. There is no difference in cost to perform the proposed modification.
Would This Proposed AD Impact Various Entities?
We have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD 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.
Would This Proposed AD Involve a Significant Rule or Regulatory Action?
For the reasons discussed above, I certify that this proposed AD:
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. 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.
We prepared a summary of the costs to comply with this proposed AD and placed it in the AD Docket. You may get a copy of this summary by sending a request to us at the address listed under ADDRESSES. Include “AD Docket No. 2004-CE-03-AD” in your request.Start List of Subjects
