Attachment of bail arm is shown in Fig. 6-13.
Check condition of the lever (3). Clean the bushing, grease it with lubricant grease and
assemble the lever with lever bracket (5). Tighten the nut slightly and secure it with the
cotter pin.

The arm must not show after installing any axial play and its travel must be continuous without
hitching.
Connect both push rod ends (2) with the lever (3).
Close the access hole by cover (1).
Check elevator deflections (see 6.4.3.3) and check plays in control (see 6.4.1.2).

6.4.1.1
Measuring procedure
Measure all plays three times and write down average values.
Perform measuring with the blocked control surfaces. Before measuring it is necessary
to push down the control surface by hand several times (max force of 5 kg (11 lbs.)) in
the direction of the control surface deflection, so that the control system is unblocked
and plays can be more easily identified.
