The biggest problem is they dont take ownership of the maintenance they carry out. Ie the dont make a statement on the M/R. This leads any proplems onto the person that release tne aircraft.
Perhaps. Or maybe if you can demonstrate that the owner did maintenance without properly documenting it, it becomes harder to prove who actually last maintained a system? If the owner is meticulous in their records and the last person to perform maintenance was the LAME that is more clear cut.
