A B2 is a LINE Licence because in BASE maintenance there is only ONE certifying signature - the C. However, the B Licenced guys are used as "Support Staff" - team/area supervisors and inspectors, supporting the C Licence Sign-Off.
So, what are all the B1/B2 LAEs & Techs signing on the job cards in the hangars?
I understood that the C Licence signature was certifying that the entire work package had been reviewed and was correct.. IE. That all necessary work had been certified in accordance with...by B1/B2s and other delegated staff etc.
I stand to be corrected of course.
