Airworthiness Directives; Cessna Aircraft Company Models 172R, 172S, 182S, 182T, T182T, 206H, and T206H Airplanes

Action

Final Rule.

Summary

The FAA supersedes 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 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 AD retains the actions required in AD 2003-24-13, corrects the applicability section, and incorporates a revised installation bulletin issued by Honeywell.

Discussion Back to Top

What events have caused this AD? 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 may 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 AD will 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 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 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.

Has FAA taken any action to this point? We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain 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. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on March 10, 2004 (69 FR 11346). The NPRM proposed to supersede AD 2003-24-13 with a new AD that 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.

Comments Back to Top

Was the public invited to comment? We provided the public the opportunity to participate in the development of this AD. The following presents the comments received on the proposal and FAA's response to each comment:

Comment Issue: AD Action Is Not Necessary Back to Top

What is the commenter's concern? The commenter states that FAA's discussion about the cause of the unsafe condition addressed in the proposed AD is unjustifiable.

The commenter states that an attentive pilot would know if the autopilot has been unintentionally engaged. The commenter also states that it is a convenience to the pilot to have the autopilot mode selector near the throttle while maneuvering during an approach or a go around that may necessitate a change in function.

The commenter states that the proposed AD is not necessary; therefore, the cost to have the software upgraded should be paid for by Honeywell.

We infer that the commenter want us to withdraw the NPRM and current AD 2003-24-13.

What is FAA's response to the concern? We do not agree with that we should withdraw the NPRM or AD 2003-24-13. The changes to the KC 140 autopilot computer system operating software required by this AD and AD 2003-24-13 will greatly limit the ability of the pilot to unintentionally engage the autopilot. The changes will also provide additional indications to the pilot that the autopilot has been engaged.

Because we continue to receive reports of related accidents involving pilots with experience ranging from novice to certified flight instructors, it is an indication that it is not obvious to all pilots that the autopilot is engaged.

We are not changing the final rule AD based on these comments.

Conclusion Back to Top

What is FAA's final determination on this issue? We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed except for minor editorial corrections. We have determined that these minor corrections:

  • Are consistent with the intent that was proposed in the NPRM for correcting the unsafe condition; and
  • Do not add any additional burden upon the public than was already proposed in the NPRM.

Changes to 14 CFR Part 39—Effect on the AD Back to Top

How does the revision to 14 CFR part 39 affect this AD? On July 10, 2002, the FAA published a new version of 14 CFR part 39 (67 FR 47997, July 22, 2002), which governs the 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 Back to Top

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:

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 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 AD. There is no difference in cost to perform the modification.

Regulatory Findings Back to Top

Will this AD impact various entities? We have determined that this AD will not have federalism implications under Executive Order 13132. This AD 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.

Will this AD involve a significant rule or regulatory action? For the reasons discussed above, I certify that this 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 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.
