Indeed, what "jacking" meant was a specific question raised by on audience member, the CASA presenter did not agree with your version of "the law". As to the CASA version of the rest of the matter of tyres and tubes,
Its in black and white in the maintenance shedule 8. In fact its number 1. May jack the aicraft but only 1 wheel at a time. Schedule 8 covered under 42.
But then where is your calibrated tooling and maintenance manual cause you will have them on hand wont you.
As for casa.
As a maintenance shop we have regular aduits. We pass an aduit. Then for an unrelated reason we have another aduit specfic to one thing. We have our process manual we we do our work too. Its approved. Just re approved. These clowns say its wrong. Wtf. When asked why its wrong. We have to go back to the office and tell you after we look at it. I said. Your the regulatorybroad you should know the answer now. Thet could answer. Their only reply was yes we here this all the time. They make up their own regs to suit themselves. So for someone to say that you cant jack a wheel is flase. Read shed 8. Black and white.
