If ESP remains engaged for 10 seconds (non-consecutive) in a 20 second interval, the system will engage the Autopilot (AFCS) in LVL-LVL mode, which then enables automatic pitch trim authority. This can be unexpected when intentionally operating the airplane in some flight conditions such as during training flights with slow flight maneuvers and power off stalls, or with erroneous airspeed indications. COMPLIANCE MANDATORY. This service document must be accomplished at the next 100-hour or 12-month (annual-type) inspection.
