(4) Limit Loads and Angles (Ref. Fig. 204/TASK 09-10-00-991-002)
(a)
In all the towing configurations, the safety pin locks the control lever on the interphone box in the disengaged position.
(b)
The maximum permitted steering-angle on each side of the aircraft centerline is only 95 degrees.
(c)
During towing, the towing angle must not be more than the angle shown on the FWD NLG doors.
NOTE : Step (c) is applicable for aircraft that have the wheel
____ steering-angle marking on the FWD NLG doors.
(d)
Tow the aircraft (slowly and smoothly) with the main landing gear:
-
the maximum towing angle in the vertical plane is 11 degrees.
-
the nose landing gear gives the limits for the maximum towing angle in the horizontal plane. (Ref. Fig. 205/TASK 09-10-00-991-004)
(e)
Use a towbar with:
-
the towing shear pins, calibration 9120 daN (20502.5716 lbf) for the protection of the landing gear against too high loads,
-
the safety shear pin, calibration 826 m.daN (6091.4453 lbf.ft) for the protection of the landing gear against too high torsion.
(f)
Use:
-
the two special fork fittings and a cable to tow the main landing gear forward or rearward. Attach these special fork fittings to the lugs at each end of the landing gear.
-
the safety shear pin, calibration 29000 daN (65194.5810 lbf) which comes with the two-fitting/cable set.
NOTE : When the engines are not installed, tow the aircraft
____
smoothly.
NOTE : It is permitted to tow the aircraft with the floor panels
____ of the cabin and/or cargo compartment(s) removed.

A. Towing (Ref. Fig. 201/TASK 09-10-00-991-020)
NOTE : We recommend that you use a towbar that has a damping system.____
(1) Towing
R (a) You can use the NLG towbar fitting to tow or push the aircraft: - with maximum weight, - with the engines between zero and idle.
R R (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)
R R (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:
R R 1_ for a tractor with a towbar, a maximum speed of 25 km/h (15.5mph) is permitted.
R R 2_ for a tractor without towbar, a maximum speed of 32 km/h (19.8mph) is permitted.
(b) Passenger/crew doors fully open and locked and/or cargo doors open in vertical position.
R 1_ the maximum speed limit is 10 km/h (6.21 mph).
