Qantas jet blows four tyres on take off at LAX

Why does it take so much time? They are only tires aren't they?

 

 

Basically, you jack it up, remove the dust cap, safety lock bolts and safety wire, break the torque, remove the nut, remove the tire, then roll on a new one, torque the nut to seating torque, then back it off, re torque it, install the nut, the locks, re-safety it, and put the dust cap on, and clamp it, safety the clamp, and down jack...the tires are extremely heavy, and a tire jack is needed, as is a tire dolly, as blown tires don't roll. Check the pressure, and release for flight.

 

Takes 1-2 guys maybe 30 minutes to do 1 tire, once they have all the stuff set up. Assuming they had enough crews and equipment, they could knock it out fast...if Quantas is run like most airlines, they don't have enough equipment or parts on hand...
