Maybe, just maybe, the cheapskate habit of using home made photocopied Jepps has bitten.
Easter weekend and all that.
Was the person charged with updating the Jepps in the Crew room around ? if not, when were they last there ?
Of course, ultimately the buck will stop with the crew, as all the signing on , signing here, signing there , accepting this, accepting that will most definitely cover checking the date & validity of the Jepps, notams (regardless of how many printers were/were not working ) etc etc.
Sign here. . . . . "IT'S MY FAULT" just once a day would cover it, rather than the plethora of signatures required.
