B757 FLT CREW HAS AN MEL ITEM THAT REQUIRES A PREFLT ENG RUN UP. CHK PRIOR TO DEP.

Narrative

ON ARR AT THE ACFT FOR ORIGINATION TO NY; UPON REVIEW OF THE LOGBOOK IT WAS NOTICED THAT A REQUIRED MPM FOR AN OPEN MEL HAD NOT BEEN ACCOMPLISHED OR SIGNED OFF SINCE THE ACFT HAD ARRIVED AT DFW. THIS MEL; FOR A MALFUNCTIONING HYD OVERHEAT LIGHT; MEL REQUIRES A MAINT CHK PRIOR TO EVERY FLT. MAINT WERE DULY CALLED AND A MECH PROMPTLY SENT; SO FAR SO GOOD. PART 1 REQUIRES THE CAPT TO NOTIFY THE AGENT OF A MAINT EVENT; SO I PROCEEDED UP THE JETBRIDGE TO INFORM THE AGENT ON HIS BEHALF. I WAS SURPRISED TO BE MET BY PAX COMING THE OTHER WAY (45 MINS PRIOR TO DEP -- LIGHT LOAD 91 PAX); MAKING IT CHAOS ON THE JETBRIDGE AND BLOCKING THE WAY FOR THE ENGINEERS TO THE FLT DECK. THE MPM WAS SIGNED OFF IN THE LOGBOOK AND THE FLT DEPARTED ON SCHEDULE. ON ARR IN LGA I RE-BOARDED THE ACFT TO RIDE THE JUMPSEAT BACK TO DFW. THE CREW IN LGA LETTING THE MAINT PERSONNEL THERE PROCEED WITH THE MPM FOR THE RETURN LEG. TO MY ASTONISHMENT; THIS INVOLVED AN ENG RUN. WE HAD NOT HAD THIS DONE IN DFW. UPON REVIEW OF THE MPM THE MECHS IN LGA SHOWED ME THAT THERE IS 2 PARTS TO THE MPM -- FOR THE ELECTRIC HYD PUMPS OR THE ENG-DRIVEN PUMPS. WE HAD HAD THE WRONG ONE DONE IN DFW -- NO ENG RUN HAD BEEN DONE. CONTRIBUTING FACTORS TO THIS INCIDENT: 1) ACR 'RUSHING CULTURE' EVEN WHEN THERE'S MASS OF TIME BEFORE DEP. 2) A GATE AGENT UNNECESSARILY LOADING THE PAX IN DFW WITHOUT COORDINATING PERSONALLY WITH THE CAPT AND HENCE RUSHING THE MAINT PERSONNEL. 3) THE CHAOTIC STATE OF THE MEL/MPM SIT WITH MANUALS SCATTERED AMONGST DIFFERENT PERSONNEL INSTEAD OF HAVING A SINGLE; SIMPLE; COORDINATED COCKPIT LIBRARY LIKE ALL FOREIGN CARRIERS DO; THAT THE FLT CREW COULD XCHK FOR MAINT.
