c)
With TN1000/13 executed, standard from ser. no. 10-133 on:
:
Adjust the stop bolt in part 10FW74 so that dimension a will be between 14,5 and
15.5 mm (.57 in. and .61 in.) see diagram 18.
Adjust the cable via the adjustment screw in part 10FW74 so that the locking pin
disengages when retracting the landing gear. The distance 1mm according to
diagram 17 also applies for the disengaged locking pin.
Don’t tighten the cable too much!
1.6.1.3 Free play
Free play between bellcrank 10FW15/1 and shaft 10FW13/1 is not allowed.
If there is any free play tighten the two securing bolts M 6x35 at the bellcrank and the
two securing bolts M6x35 inside the landing gear box at the shaft with a 10 mm open-
end wrench. If there is still some free play, the bolts should be removed and the holes
drilled out and reamed to diameter 8 H7. M 8 x 40 LN 9037 bolts should then be
installed. The bolts for installation inside the landing gear box must be shortened to
36mm.
1.6.2
Main wheel (Version with nose wheel)
1.6.2.1 Undercarriage control circuit
see diagram 8
In the retracted position the undercarriage is locked by an overcentre device. In the
extended position the lock is by a locking notch at pushrod 5FW38 in the rear cockpit.
A gas strut reduces the retraction force and keeps the undercarriage in the overcentre
locking position (retracted and extended).
1.6.2.2 Adjustment
a)
Overcentre lock in retracted position:
Adjustment at the adjustment screw
between landing gear operating lever 5FW8 and the bellcrank 5FW36.
The stop is located at the pushrod 5FW38 and stops against the pedestal 5FW41.
Adjust this stop after adjusting the lock in the extended position see b) by gluing
slotted shims onto the stop-sleeve of pushrod 5FW38.
b)
In extended position
(landing gear struts over centre) a max. free play of ca. 0.5
mm (0.02 in.) between the lock at pushrod 5FW38 and the locking plate 5FW35 is
allowed. Adjustment at the rod end in pushrod 5FW37 between 5FW38 and 5FW
36.
1.6.2.3 Free play
Free play between lever 5FW8 and the upper strut 5FW12 is not allowed.
If there is any free play, the two securing bolts M 6 x 40 should be tightened with a 10
mm open-end wrench. If there is still some free play, the bolts should be removed and
the holes drilled out and reamed to diameter 8 H7. M 8 x 40 LN 9037 bolts should
then be installed.

Fin tank
The fin ballast tank is constructed as integral tank.
a)
Adjustment
The release cable must be adjusted so that the cable just becomes loose when
the handle is parallel to the fuselage wall.
b)
Inspection
According to sect. 2.2 a special inspection is to be carried out on the fin
ballast tank system at each annual inspection.
The dump time of the full fin tank should be timed and should not exceed
120 seconds.
Check the calibration of the outside air temperature gauge (in the DEI-NT).
Up to ser.no. 10-100 and ser.no. 10-102 to 10-127:
Remove the tailwheel and the cover plate in the tailwheel box. Check the
control cable and the lever of the valve carefully for wear. Check the control
cable at the operating handle too. If the cable or the lever is worn, further use
of the fin tank is prohibited. Please contact the manufacturer for a detailed
repair instruction.
Ser.no. 10-101, and from ser. no. 10-128 on:
Check the control cable at the operating handle and at the dump valve
(installed in the lower rudder mounting bracket). If the cable is worn, further
use of the fin tank is prohibited.
