TOWBARLESS TOWING
EQUIPMENT
Towbarless towing vehicles that are specifically accepted for this type
of airplane are listed in the AMM Chapter 9.
PROCEDURES
Towbarless Towing operation is accomplished following the steps
below:
WARNING:
WHEN THE ENGINES AND APU ARE RUNNING
DURING THE TOWING PROCEDURES MAKE SURE
THAT ALL PERSONS ON THE GROUND STAY AWAY
FROM HAZARDOUS AREAS.
− Put the tug vehicle in the correct position near the nose wheels.
− Remove the wheel chocks from the main wheels.
− Connect the tug vehicle to the airplane.
− Release the emergency/parking brake. Check if the brake ON light
goes off.
NOTE: - Coordinate with ground personnel to release and apply the
airplane emergency/parking brake.
- To prevent hydraulic fluid transference from system 1 to
system 2 or vice versa, always apply brakes with the pedals
before pulling and releasing the emergency/parking brake
handle.
− Tow the airplane slowly straight ahead before turning. Complete
the airplane towing in a straight line for a minimum of 3 m (10 ft) in
order to align the steering as close as possible to the zero-degree
position.
NOTE: Do not stop the airplane when turning if it is not necessary.

ANGLE IS 170º TO THE RIGHT AND 170º TO THE

EXCEEDED DAMAGE TO THE NOSE LANDING GEAR
CAN OCCUR. TAKEOFF IS NOT ALLOWED WITH
