_______ THE DANGEROUS AREAS AROUND THE TOW VEHICLE, TOW BAR, NOSE WHEELS, AND THE MAIN WHEELS. PERSONS ON THE GROUND MUST KNOW IT IS POSSIBLE TO BE RUN OVER BY THE NOSE WHEELS, MAIN WHEELS, AND THE TOW VEHICLE. THIS IS BECAUSE THE AIRPLANE WILL CHANGE POSITION DURING PUSHBACK AND TOWING. MAKE SURE YOU KEEP A MINIMUM OF 10 FEET SEPARATION BETWEEN PERSONS ON THE GROUND AND THE EQUIPMENT THAT MOVES. IF YOU DO NOT KEEP THE MINIMUN DISTANCE, A FATAL INJURY CAN OCCUR.
(a)
Make sure the persons that work near the areas that follow, know the pushback hazard zones as shown in Figure 207A:
-
tow vehicle
-
tow bar
-nose wheels
-main wheels.
(b)
Before you park the airplane, complete towing with a 12-foot straight path.
NOTE: This will release torsional stress applied to the
____ landing gear components and tires during a turn.
CAUTION: IF YOU HAVE DISCONNECTED THE TORSION LINKS, MAKE SURE THE
_______ TORSION LINKS DO NOT DROP. DAMAGE TO THE SQUAT SWITCH MOUNTING BRACKET CAN OCCUR.
(c) If the torsion links were disconnected, align the links during the last few feet of the tow so that the torsion link bolt can be installed.
