Narrative:

Takeoff and climb to cruise were normal. About 10 mins after we reached cruising altitude of 15000 ft; we received a ccas message indicating engine on the cap and a fuel clog light on the #2 engine. Captain called for identify and cancel; which I did then I retrieved my book and began to look up the procedure. No actions are recommended in the book and it even states that the aircraft may continue to fly multiple legs after a single fuel clog is annunciated. Once we landed; the light extinguished before any maintenance action was taken. The captain advised maintenance and dispatch about the problem after we landed. The dispatcher; the captain; and I were uncomfortable with flying the aircraft back without further investigation from on-site maintenance personnel. Maintenance control kept pressuring the 3 of us to return the aircraft so that they would be able to do the maintenance there. Instead of offering to have the fuel filter checked; maintenance control continued to pressure us towards returning the aircraft. They also continued to pressure the captain to change his write-up to an 'information to maintenance.' in the meantime the flight was canceled due to volcanic ash. While we were on the ground maintenance showed up to look at the engine. The mechanic inspected one of the propeller blades on the #1 engine; but I never actually saw him inspect the #2 engine or the fuel filter. The next morning we arrived to take a rescheduled flight in the same aircraft. A few mins after we reached our cruising altitude; we received a ccas message and a fuel clog light. The light remained on throughout the cruise; approach and landing phases of the flight; then extinguished during the taxi. The captain wrote up an information to maintenance once we blocked in at the gate; so there would not be any confusion as to whether the problem still existed.

Title: ATR-72 FLT CREW HAS A CCAS FUEL FILTER CLOG MESSAGE WHILE ENRTE.

Narrative: TKOF AND CLB TO CRUISE WERE NORMAL. ABOUT 10 MINS AFTER WE REACHED CRUISING ALT OF 15000 FT; WE RECEIVED A CCAS MESSAGE INDICATING ENG ON THE CAP AND A FUEL CLOG LIGHT ON THE #2 ENG. CAPT CALLED FOR IDENT AND CANCEL; WHICH I DID THEN I RETRIEVED MY BOOK AND BEGAN TO LOOK UP THE PROC. NO ACTIONS ARE RECOMMENDED IN THE BOOK AND IT EVEN STATES THAT THE ACFT MAY CONTINUE TO FLY MULTIPLE LEGS AFTER A SINGLE FUEL CLOG IS ANNUNCIATED. ONCE WE LANDED; THE LIGHT EXTINGUISHED BEFORE ANY MAINT ACTION WAS TAKEN. THE CAPT ADVISED MAINT AND DISPATCH ABOUT THE PROB AFTER WE LANDED. THE DISPATCHER; THE CAPT; AND I WERE UNCOMFORTABLE WITH FLYING THE ACFT BACK WITHOUT FURTHER INVESTIGATION FROM ON-SITE MAINT PERSONNEL. MAINT CTL KEPT PRESSURING THE 3 OF US TO RETURN THE ACFT SO THAT THEY WOULD BE ABLE TO DO THE MAINT THERE. INSTEAD OF OFFERING TO HAVE THE FUEL FILTER CHKED; MAINT CTL CONTINUED TO PRESSURE US TOWARDS RETURNING THE ACFT. THEY ALSO CONTINUED TO PRESSURE THE CAPT TO CHANGE HIS WRITE-UP TO AN 'INFO TO MAINT.' IN THE MEANTIME THE FLT WAS CANCELED DUE TO VOLCANIC ASH. WHILE WE WERE ON THE GND MAINT SHOWED UP TO LOOK AT THE ENG. THE MECH INSPECTED ONE OF THE PROP BLADES ON THE #1 ENG; BUT I NEVER ACTUALLY SAW HIM INSPECT THE #2 ENG OR THE FUEL FILTER. THE NEXT MORNING WE ARRIVED TO TAKE A RESCHEDULED FLT IN THE SAME ACFT. A FEW MINS AFTER WE REACHED OUR CRUISING ALT; WE RECEIVED A CCAS MESSAGE AND A FUEL CLOG LIGHT. THE LIGHT REMAINED ON THROUGHOUT THE CRUISE; APCH AND LNDG PHASES OF THE FLT; THEN EXTINGUISHED DURING THE TAXI. THE CAPT WROTE UP AN INFO TO MAINT ONCE WE BLOCKED IN AT THE GATE; SO THERE WOULD NOT BE ANY CONFUSION AS TO WHETHER THE PROB STILL EXISTED.
