Issue:
1

Date: 11th December 2000

Subject:

ASK 13 and ASK 18 Elevator Engagement

Applicability:

Schleicher ASK 13 and ASK 18

Accomplishment: At next and subsequent C of A inspections and during inspections of rear fuselage.

Reason:

Incorrect positioning of elevator linkage pivots or damage during rigging or following accident damage causing misalignment of elevator control arm ball bearing in drive rod and possible disconnection in extreme conditions.

Instructions:

It may be necessary to remove one half of the elevator to accomplish this inspection. Inspect the engagement of the elevator control arm ball bearing into the elevator control rod drive “U”. The engagement of the bearing must be at or slightly below the centreline of the “U” during all positions of elevator travel. To correct an out of tolerance condition replace any worn or incorrect parts with genuine Schleicher items if condition still exists replace or modify link upper aft bracket. The K8 “Automatic Elevator Connection” drawing may be used as a guide.
