2. Each Crew Chief will be thoroughly familiar with the contents of this checklist. There may be specific weather or facility restriction/condition that might require variations to this checklist. When these conditions occur, the aircraft commander has the final authority for variations.

The Crew Chiefs will perform the following operations:

a. Starts external power (when required by alert response or if signaled by the pilot).

b. Removes pitot covers.

c. If an astro-tracker is installed, remove its cover.

d. Removes the crew entrance ladder on the pilot's side of the aircraft (or when an immediate engine start is not required, both crew ladders are removed.

e. Stow ladder peg's.

f. If an engine start is to be accomplished immediately, the Crew Chief stands fire guard and clears the pilot to start the left engine. When the pilot closes his side of the canopy and after the left engine is definitely started, the Crew Chief will remove electrical connections, ground static wires and air conditioner/heater.

g. The Crew Chief removes the entrance ladder on the navigator's side (unless already removed earlier) and stows ladder peg. Crew Chief then clears pilot to start right engine while the Crew Chief stands fire guard.

h. After the second engine has started, and when the pilot turns on the taxi light, the Crew Chief will pull the nose gear pin, will remove the chocks and will position himself to the left and forward of the aircraft, from where he will signal the pilot for taxiing. The taxi light will not be illuminated, nor will the nose gear pin be pulled, except on taxi exercises or postures which require aircraft movement.
