SECTION IIOPERATING PROCEDURE

CRJ TOW BAR ASSEMBLY

A. ATTACHING TOW BAR TO AIRCRAFT

The CRJ can be towed forward or pushed aft on hard surfaces using the CRJTow Bar. The Tow Bar attaches to the nose landing gear by means of the extensionpins on the head. When the tow bar assembly is lined up with the nose gear, not theaircraft, the extension pins will have to be manually locked in position on the noselanding gear by the operator.

B. ATTACHING TOW BAR TO TOW TRACTOR

Once the tow bar is securely attached to the nose landing gear, the tow tractorshould be placed at the centerline of the Tow Bar. The operator must manually lift thetow bar to engage with the tow tractor and install the locking pin.

C. PUSHING THE AIRCRAFT

This must be done in accordance with the instructions in Canadair RegionalJet Facility and Equipment Planning Manual.

CAUTION: If at any time the jack knife protection torque shear pin yieldsor breaks, carefully bring the aircraft to a stop. Before pushing or tow can be continueda new jack knife protection torque shear pin must be inserted. Use only a HallIndustries shear pin as follows, Part Number CRJ-100-11-2. The adaptor unit comeswith two extra shear pins. These are to be stored in the adaptor, to prevent delays inreplacing the shear pin.

D. DISCONNECTING TOW BAR FROM AIRCRAFT

Release the extension pins manually to release the head from the nose landinggear on the aircraft. Carefully move the tow bar and tow tractor clear of the aircraft. Inthe case of the extension pin not releasing, pull the shear pin from the adaptor and head.This will allow free play to the head and the extension pin will now release. The tow barassembly must be lined up with the nose gear, not the aircraft.
