 AD/INST/47 Amdt 1 (Continued)

           This Amendment becomes effective on 27 June 2001.

           Background:  This original issue of this Directive required inspection of KC 225 AFCS to determine the computer modification status, deactivation of any units with only Mods 1 and/or 2 incorporated, and the installation of an appropriate placard if the unit is deactivated/inoperative. The original issue also provided, as an alternative method of compliance, the option of installing a unit that incorporated Mod 3 or higher.

           The original issue of the Directive was issued as a result of several reports that the AFCS was disconnecting without warning in a gross mistrim configuration. The actions specified by the Directive were intended to prevent an undesirable autotrim command that the autopilot cannot detect in the required time, which could result in the aeroplane deviating from the selected altitude, or the autopilot could disconnect without warning. This in turn could result in heavy loads at the control column and such loads in the pitch axis could result in loss of control of the aeroplane.

           This amendment is issued to correct the title of the Directive.

           The original issue of this Airworthiness Directive became effective on 15 June 2001.
