Thanks for the link.
Too me it looks like once you have an A&P licence you can certify for any type , even without having type specific training or any previous type experience..So a mechanic that has worked on say Caravans and twotters his entire life could take a job at United and certify for work on a 747-400.
What a **** system, and somewhat puts mechanics in a dangerous position, particularly being unaware of safety critical systems, that you are made aware of on type specific training..
