Narrative:
This was the first flight of the day for the aircraft and first flight together as a crew. I was also receiving a line check. It was a very busy departure time with all the required briefings and inspections to be conducted. While reviewing the maintenance log, I noted MEL 28-23-01 for the right fuel boost pump. While reviewing the required items with the crew I noted that the circuit breaker for the right boost pump cbp-2 (G10) was not pulled. I called maintenance to verify the status of this deferral and to find out why the breaker was not pulled and collared. Within a short period of time, line maintenance arrived and stated the first officer seat must have bumped the collar off and pushed the breaker in. I asked him if he really thought that the seat could remove a collar and push a breaker in. He stated 'yes, it happens all the time.' I have had many instances of the wrong breaker or no breaker being pulled and collared according to the MEL. I also routinely hear that when a breaker is out that the seatbelt shoulder harness must have pulled it out. It is then pushed in by maintenance and the operation continues. In this cae, the breaker to a fuel pump was not deactivated and could have serious consequences. I am not sure if we have an issue with seats that sabotage circuit breakers or mechanics that do not read the MEL.

Title: A CANADAIR CL65 CAPT RPTS A BOOT PUMP WAS DEFERRED PER THE MEL BUT DID NOT HAVE THE CIRCUIT BREAKER PULLED AND COLLARED PER THE MEL.
Narrative: THIS WAS THE FIRST FLT OF THE DAY FOR THE ACFT AND FIRST FLT TOGETHER AS A CREW. I WAS ALSO RECEIVING A LINE CHK. IT WAS A VERY BUSY DEP TIME WITH ALL THE REQUIRED BRIEFINGS AND INSPECTIONS TO BE CONDUCTED. WHILE REVIEWING THE MAINT LOG, I NOTED MEL 28-23-01 FOR THE R FUEL BOOST PUMP. WHILE REVIEWING THE REQUIRED ITEMS WITH THE CREW I NOTED THAT THE CIRCUIT BREAKER FOR THE R BOOST PUMP CBP-2 (G10) WAS NOT PULLED. I CALLED MAINT TO VERIFY THE STATUS OF THIS DEFERRAL AND TO FIND OUT WHY THE BREAKER WAS NOT PULLED AND COLLARED. WITHIN A SHORT PERIOD OF TIME, LINE MAINT ARRIVED AND STATED THE FO SEAT MUST HAVE BUMPED THE COLLAR OFF AND PUSHED THE BREAKER IN. I ASKED HIM IF HE REALLY THOUGHT THAT THE SEAT COULD REMOVE A COLLAR AND PUSH A BREAKER IN. HE STATED 'YES, IT HAPPENS ALL THE TIME.' I HAVE HAD MANY INSTANCES OF THE WRONG BREAKER OR NO BREAKER BEING PULLED AND COLLARED ACCORDING TO THE MEL. I ALSO ROUTINELY HEAR THAT WHEN A BREAKER IS OUT THAT THE SEATBELT SHOULDER HARNESS MUST HAVE PULLED IT OUT. IT IS THEN PUSHED IN BY MAINT AND THE OP CONTINUES. IN THIS CAE, THE BREAKER TO A FUEL PUMP WAS NOT DEACTIVATED AND COULD HAVE SERIOUS CONSEQUENCES. I AM NOT SURE IF WE HAVE AN ISSUE WITH SEATS THAT SABOTAGE CIRCUIT BREAKERS OR MECHS THAT DO NOT READ THE MEL.
