Plain English Summary

3/10 complexity

Requires operators of aircraft fitted with the Honeywell KC 225 AFCS to inspect the autopilot to identify installed computer modification (Mod) levels. If only Mod 1 and/or 2 are fitted, the autopilot must be deactivated (pull and band the circuit breaker) and a clear cockpit placard installed; alternatively the unit may be returned to Honeywell for upgrade or replacement to include Mod 3. The Directive’s stated purpose is to avoid unexpected autotrim or autopilot disconnects that could produce heavy control loads and risk loss of control.

Requirement: 1. Inspect the KC 225 AFCS in accordance with Honeywell Installation Bulletin (IB) 472 Alert, Revision 1, dated January 2001, to determine the currently installed computer modifications (Mods).

2. If the Requirement 1 inspection determines that only Mods 1 and/or 2 are incorporated, accomplish the following in accordance with IB 472 Alert, Revision 1:

Deactivate the KC 225 AFCS by pulling and banding the autopilot circuit breaker(s) to prevent operation of the KC 225 AFCS in flight; and

b. Fabricate a placard that indicates the KC 225 AFCS is inoperative and install this placard on the instrument panel within the pilot’s clear view. The placard should use letters of at least 2.5 mm (0.10 inches) in height and contain the following words:

"KC 225 AFCS INOPERATIVE"

An optional alternative to the deactivation of the AFCS with only Mods 1 and/or 2 installed is to either:

Return the AFCS to the Honeywell Service Center for modification to install Mod 1, 2 and 3 (or higher); or

Contact Honeywell Product Support for a warranty replacement KC 225 AFCS that contains Mod 1, 2 and 3 (or higher) levels.

Note 2: If either of the optional alternates is adopted, the AFCS must remain deactivated and placarded in accordance with Requirement 2 until an AFCS unit with at least Mods 1, 2 and 3 is installed.

3. If the Requirement 1 inspection determines that no Mods are installed or at least Mods 1, 2, and 3 are installed, ensure that the aircraft records identify AFCS Mod status in accordance with IB 472 Alert, Revision 1. This Directive requires no further action.

Note 3: FAA AD 2001-10-09 Amdt 39-12235 refers.

Compliance: For Requirement 1 - Remains unchanged as ‘Within the next 10 hours time-in-service after the effective date of the original issue of the Directive’.

For Requirement 2 - Remains unchanged as ‘Before further flight after the Requirement 1 inspection’.

For Requirement 3 - Remains unchanged as ‘Before further flight after the Requirement 1 inspection’.
