FOR MORE INFO: Companies can write their own procedure manuals or given some other name, and get it approved by their own Quality people and their own Licensing Authority!!! It gives more flexible operation for their own convenience. Of course, AMM gives you all the procedures and everything else but on certain Chapters(systems) if the company has got their own Procedures Manual , then that takes priority over the AMM. I am sure there will be lots of engineers dealing with 3rd party customers and know about these so-called procedures of individual airlines, even though they might be operating the same a/c type !!!!
