| Background: | Honeywell International, the manufacturer of the SPZ200 autopilot system installed on the EADS-CASA C-212 series aircraft, has identified a series of servo-motors, P/N 4006719-904 and P/N 4006719-913, designed for use in the SPZ200 autopilot system, whose failure can lead to a potential unsafe flight condition. To address and correct this situation, Honeywell International has published ASB 4006719-22-A0016 (Revised), that indentifies the affected servo-motors, recommending the removal of these units from the aircraft and including modification instructions to be accomplished prior to reinstallation. |
| EADS-CASA has determined that the flight safety of the C-212 aircraft is at risk. Consequently, SB-212-22-16 has been published to advise C-212 operators of this condition and to recommend that the affected servo-motors are modified or replaced with modified units. |
