TOWBAR TOWING
EQUIPMENT
Ground towbar towing is normally accomplished by using ground
support equipment P/N 01-1201-0000 (towbar) and 01-0582-0010
(towbar attachment) coupled to the nose landing gear.
The towbar incorporates breakable sections (fuse) with the purpose of
causing the towbar to break in case of any towing abnormality, to
protect the airplane structure or the nose landing gear from damage.
Maximum towbar fuse push/pull design force is 4418 kgf (9740 lbf).
Maximum design torque is 4300 N.m (3171.5 lbf.ft).
