Unsafe condition
This AD was prompted by a report that for airplanes with blended winglets, the nose-up pitch trim limit and associated warning for the horizontal stabilizer control system will allow the stabilizer position to be set outside acceptable limits for a mis-trimmed takeoff condition. We are issuing this AD to prevent takeoff with a stabilizer position set outside acceptable limits for a mis-trimmed takeoff condition. Settings outside of the appropriate pitch trim limits could result in loss of controllability of the airplane during takeoff.
Affected ADs
None.
