Undercarriage
1.6.1
Main wheel (Version without nose wheel)
1.6.1.1 Undercarriage control circuit
see diagram 12 and 7 (inside landing gear box)
In the retracted position the undercarriage is locked by an over centre device.
In the extended position the lock is by a locking notch at pushrod 10FW38 in the rear
cockpit and additionally by over centre locking force generated by a rubber buffer
A gas strut reduces the retraction force and keeps the undercarriage in the retracted
overcentre locking position.
With TN1000/13 executed, standard from ser. no. 10-133 on:
An additional landing gear positive locking device (notch and latch at the
landing gear struts) secures the landing gear in the extended position.
An additional catch in the front upper area of the landing gear box secures the
landing gear in retracted position. See diagrams 17 and 18.
1.6.1.2 Adjustment
a) In extended position (landing gear struts over centre) a max. free play of ca. 0.5
mm (0.02 in.) between the notch at pushrod 10FW38 and the locking plate
10FW35 (see detail X in diagram 12) is allowed when the landing gear handle is
pushed forward with a force of approx. 200N (44 lbs.), measurement with main
wheel not resting on the ground. Adjustment should be made at the rod end in
pushrod 10FW20 at the connection to the actuating lever 10Fw15/1.
Adjustment of the rubber buffer:
a) Screw out the rubber buffer just so far that it touched the GFRP block (L/G
extended).
b) Retract the L/G a little and screw out the rubber buffer for another 4-4.5mm
(.16-.18 in.). Fix in position by counter rotating the nut.
With TN1000/13 executed, standard from ser. no. 10-133 on:
screw out the rubber buffer for only 2 - 2.5mm (.08 -.10 in.).
c) Sit in the front cockpit and extend the L/G. You must feel an over centre
locking force.
d)Retract the L/G, you must feel a strong locking force. If necessary increase the
locking force by unscrewing the rubber buffer or decrease the locking force by
screwing in the buffer.
b) Overcentre lock in retracted position:
Adjustment of the overcentre locking force inside the landing gear box is at the
rod ends in the two pushrods 10FW14/3 at their connections to shaft 10FW13/1.
The overcentre travel may be adjusted by changing the thickness of the stop-
blocks located at the roof of the landing gear box.
Warning:
If you have adjusted the overcentre locking force don’t fail to readjust
the locking in extended position see a).
