gd44 you are mistaken with you comment that Monarch maintain the GSM B767.
Monarch do carry out most of the hangar checks but only carry out what they are asked to do.
They have no control over what is called up on the checks and the day to day running of the aircraft.
I am sorry, but a few days in a hangar between "C" checks is no way being responsible for maintaining an aircraft.
I stand Corrected.
