 A. Towing
 (1) Towing
 (Ref. Fig. 201/TASK 09-10-00-991-020)

 NOTE : We recommend that you use a towbar that has a damping system.
____
 (a)
 You can use the NLG towbar fitting to tow or push the aircraft:

 -
with maximum weight,

 -
with the engines between zero and idle.

 (b)
 You can use the MLG attachments to tow the aircraft:

 -with the engines stopped,
 -when it is bogged.

 (c)
 Do not tow the aircraft if the dimension H is more than 300 mm (11.8110 in.). If you do, you can cause damage to the cams that make the nose gear wheels go back to the center position. (Ref. Fig. 202/TASK 09-10-00-991-019)

 Maximum Extension of the Nose Gear Shock Absorber during Towing
 Figure 202/TASK 09-10-00-991-019

 (d) Keep a minimum of 3 m (9.84 ft.) separation from the nose wheels, towbar and tractor while the aircraft moves. (Ref. Fig. 201/TASK 09-10-00-991-020)
 (2) Speed Limits
 (a)
 Door closed and locked or removed:

 (b)
 Passenger/crew doors fully open and locked and/or cargo doors open in vertical position:

 1_ for a tractor with a towbar, a maximum speed of 25 km/h (15.5
 mph) is permitted,
 2_ for a tractor without towbar, a maximum speed of 32 km/h (19.8
 mph) is permitted.

 1 the maximum speed permitted is 10 km/h (6.21 mph).
_
 (c) In wind conditions, calculate the permitted towing speed before towing:
 1 Measure the wind speed.
_
 2 Do a check of aircraft stability (Ref. TASK 05-57-00-200-001).

_
 3 Subtract measured wind speed from wind speed limit shown on

_ the stability curve. This gives the maximum permitted towing speed.
