Narrative:

At 2500 ft MSL first officer called for flaps 8 degrees on approximately a 7 mi right base for runway. Captain selected flaps 8 degrees; which was followed immediately by a flaps fail master caution message. Advised ATC of the need for delay vectors and assigned a climb to 3000 ft MSL. First officer maintained PF status; captain ran QRH for flaps fail and subsequent zero flap landing was briefed for runway (visual; backed up by ILS). ATC was advised and the emergency declared. Dispatch notified via ACARS. Flight attendant briefed on the situation and plan; including to not brace the cabin for landing. Passenger updated on reason for lengthy vectors and abnormal landing; including high approach speed and fire trucks rolling as a precaution. Aircraft control xferred to captain and approach flown at 46000 pounds 174 KT speed. Touchdown was gentle with maximum reverse and braking until stopping assured. Brakes never exceeded 8 on btms (brake temperature monitoring system). Possible faulty flap electronic control unit (fecu)? Logbook indicated flaps failed on 2 previous flts in may as well. On initial flap selection handle was not inadvertently moved past position and then returned to flaps 8 degrees.

Title: CARJ EXPERIENCES FAILURE OF FLAPS TO EXTEND FOR LNDG.

Narrative: AT 2500 FT MSL FO CALLED FOR FLAPS 8 DEGS ON APPROX A 7 MI R BASE FOR RWY. CAPT SELECTED FLAPS 8 DEGS; WHICH WAS FOLLOWED IMMEDIATELY BY A FLAPS FAIL MASTER CAUTION MESSAGE. ADVISED ATC OF THE NEED FOR DELAY VECTORS AND ASSIGNED A CLB TO 3000 FT MSL. FO MAINTAINED PF STATUS; CAPT RAN QRH FOR FLAPS FAIL AND SUBSEQUENT ZERO FLAP LNDG WAS BRIEFED FOR RWY (VISUAL; BACKED UP BY ILS). ATC WAS ADVISED AND THE EMER DECLARED. DISPATCH NOTIFIED VIA ACARS. FLT ATTENDANT BRIEFED ON THE SITUATION AND PLAN; INCLUDING TO NOT BRACE THE CABIN FOR LNDG. PAX UPDATED ON REASON FOR LENGTHY VECTORS AND ABNORMAL LNDG; INCLUDING HIGH APCH SPD AND FIRE TRUCKS ROLLING AS A PRECAUTION. ACFT CTL XFERRED TO CAPT AND APCH FLOWN AT 46000 LBS 174 KT SPD. TOUCHDOWN WAS GENTLE WITH MAX REVERSE AND BRAKING UNTIL STOPPING ASSURED. BRAKES NEVER EXCEEDED 8 ON BTMS (BRAKE TEMP MONITORING SYS). POSSIBLE FAULTY FLAP ELECTRONIC CTL UNIT (FECU)? LOGBOOK INDICATED FLAPS FAILED ON 2 PREVIOUS FLTS IN MAY AS WELL. ON INITIAL FLAP SELECTION HANDLE WAS NOT INADVERTENTLY MOVED PAST POS AND THEN RETURNED TO FLAPS 8 DEGS.
