LSA mechanic or A&P mechanic (Airframe and Power plant)
Tools needed:

wrench size 7/16 in (11)

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.
NOTE
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 Check of plays in control
Admissible plays in control are mentioned in the following table:
Control Admissible plays Area to measure play
longitudinal
4 mm
max. 5/32 in
at the end of the control stick in longitudinal
axis of the airplane
lateral
4 mm
max. 5/32 in
at the end of the control stick in lateral axis of
the airplane
directional
5 mm
max. 3/16 in
on pedals in longitudinal axis of the airplane
trim tabs

max. 1/8 in
at the end of the trim tab

CAUTION
If the measured plays exceed values mentioned in the table then eliminate the cause of it
and repeat measuring.
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.
