CH-47F: Another Tow Option for Chinook


This article initially appeared in PS 795 (Feb '19), pp. 22-23.

Mechanics,

If your unit still has the Chinook’s old single axle/wheel tow bar, you have to rotate the left rear wheel 120 degrees before hookup. That’s to keep the landing gear from snapping during towing.

Page 37 of PS 662 (Jan 08) has the complete scoop:
   
​But if you have the newer, two-wheel tow bar, NSN 1730-01-562-4023, which attaches to both aft wheels, towing your Chinook is a whole lot easier. With the tow bar attached to both wheels, you don’t have to rotate the aft left wheel.
 
Two wheel tow bar option available

The two-wheel tow bar keeps both wheels aligned during ground handling and helps prevent damage to the wheels, spindle and landing gear. The tow bar turns both aft landing gears during a turn.

The tow bar has a commercial operator and maintenance manual, so make sure you refer to it when operating the tow bar.

Note that this tow bar is listed as a part of the special tools and test equipment (STTE) and peculiar ground support equipment (PGSE), LIN T59439 in TB 1-1520-271-20-01.

If you have problems with the tow bar or its components, don’t try to make a repair. Instead, replace the broken part from this list:
