Deviation / Discrepancy - Procedural Published Material / Policy
I approached Aircraft X in the hanger. I and a fellow mechanic were accomplishing scheduled Maintenance Check. During my approach; I noticed one of the Maintenance Supervisors coming down from the airplane with something in his hand. I immediately asked him politely if he removed something from the Aircraft. His reply was snide and rude saying: 'I'm taking stuff'. I immediately asked him again. He then left the airplane. After calling [another Supervisor] it was determined that [Supervisor 1] took items from the Aircraft that are subject to inspection on the current check that were previously signed for and are also subject to the Aircraft's minimum required equipment. [Supervisor 1] blatantly violated [company] procedures and did not make a logbook entry for the parts removed. Upon speaking to [Supervisor 2] and my current manager; the items were returned.
Maintenance Technician reported observing a Company Supervisor improperly removing items subject to inspection from aircraft without documentation.
