Narrative:

On approach to runway 18L during configuration change from flaps 20 to flaps 30, a 'flaps fail' EICAS message illuminated. The approach was discontinued, QRH was followed, dispatch contacted for landing data and both flight attendant and passengers were briefed. An emergency was declared and crash fire rescue equipment stand-by assistance requested. An uneventful landing was performed on runway 18L. A maintenance logbook entry was made establishing the time of failure as per company manuals and flap ad. Mechanics met the aircraft at the gate, reset the flaps and cleared the write-up. The aircraft was returned to service. Supplemental information from acn 540179: on approach to runway 26L, during configuration change from flaps 20 to flaps 30 a 'flaps fail' EICAS message illuminated. The approach was discontinued, QRH was followed, dispatch contacted for landing data (via ZZZ1 station, as ZZZ2 radio was useless) and both flight attendant and passengers were briefed. An emergency was declared and crash fire rescue equipment stand-by assistance requested. An uneventful landing was made on runway 26L. A maintenance logbook entry was made establishing the time of failure as per company manuals and flap ad. Contract mechanic met the aircraft at the gate. Preparations were made for a ferry flight back to ZZZ. Callback conversation with reporter revealed the following information: the reporter stated on two consecutive back to back flts with the same airplane had to declare two emergencies due to trailing edge flap failure to extend from 20 degrees to 30 degrees. Both required flaps 20 degree lndgs at 173 knots. On termination of the first flight, the maintenance tech reset the flaps and cleared the writeup. The reporter said the importance of the actual time of failure required by the airworthiness directive opens up a 72 hour window in which if another failure occurs the airplane must be removed from service for a fix. The second flight was a repeat of the first 'flap fail' message and emergency declared. The airplane was maintenance ferried for repair. This airplane was the third airplane delivered and has a lot of time and some time back was taken out of service and had every flap component replaced. The reporter stated the main landing gear tires are speed rated for 182 miles per hour.

Title: A CANADAIR CL-65 CAPT RPTS TWO CONSECUTIVE EMERGENCIES DECLARED CAUSED BY EICAS 'FLAPS FAIL' MSG WHEN CHANGING FROM FLAPS 20 DEGS TO FLAPS 30 DEGS.

Narrative: ON APCH TO RWY 18L DURING CONFIGURATION CHANGE FROM FLAPS 20 TO FLAPS 30, A 'FLAPS FAIL' EICAS MSG ILLUMINATED. THE APCH WAS DISCONTINUED, QRH WAS FOLLOWED, DISPATCH CONTACTED FOR LNDG DATA AND BOTH FA AND PASSENGERS WERE BRIEFED. AN EMER WAS DECLARED AND CFR STAND-BY ASSISTANCE REQUESTED. AN UNEVENTFUL LNDG WAS PERFORMED ON RWY 18L. A MAINT LOGBOOK ENTRY WAS MADE ESTABLISHING THE TIME OF FAILURE AS PER COMPANY MANUALS AND FLAP AD. MECHANICS MET THE ACFT AT THE GATE, RESET THE FLAPS AND CLRED THE WRITE-UP. THE ACFT WAS RETURNED TO SVC. SUPPLEMENTAL INFO FROM ACN 540179: ON APCH TO RWY 26L, DURING CONFIGURATION CHANGE FROM FLAPS 20 TO FLAPS 30 A 'FLAPS FAIL' EICAS MSG ILLUMINATED. THE APCH WAS DISCONTINUED, QRH WAS FOLLOWED, DISPATCH CONTACTED FOR LNDG DATA (VIA ZZZ1 STATION, AS ZZZ2 RADIO WAS USELESS) AND BOTH FA AND PASSENGERS WERE BRIEFED. AN EMER WAS DECLARED AND CFR STAND-BY ASSISTANCE REQUESTED. AN UNEVENTFUL LNDG WAS MADE ON RWY 26L. A MAINT LOGBOOK ENTRY WAS MADE ESTABLISHING THE TIME OF FAILURE AS PER COMPANY MANUALS AND FLAP AD. CONTRACT MECH MET THE ACFT AT THE GATE. PREPARATIONS WERE MADE FOR A FERRY FLT BACK TO ZZZ. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED ON TWO CONSECUTIVE BACK TO BACK FLTS WITH THE SAME AIRPLANE HAD TO DECLARE TWO EMERGENCIES DUE TO TRAILING EDGE FLAP FAILURE TO EXTEND FROM 20 DEGS TO 30 DEGS. BOTH REQUIRED FLAPS 20 DEG LNDGS AT 173 KNOTS. ON TERMINATION OF THE FIRST FLT, THE MAINT TECH RESET THE FLAPS AND CLRED THE WRITEUP. THE RPTR SAID THE IMPORTANCE OF THE ACTUAL TIME OF FAILURE REQUIRED BY THE AIRWORTHINESS DIRECTIVE OPENS UP A 72 HR WINDOW IN WHICH IF ANOTHER FAILURE OCCURS THE AIRPLANE MUST BE REMOVED FROM SVC FOR A FIX. THE SECOND FLT WAS A REPEAT OF THE FIRST 'FLAP FAIL' MSG AND EMER DECLARED. THE AIRPLANE WAS MAINT FERRIED FOR REPAIR. THIS AIRPLANE WAS THE THIRD AIRPLANE DELIVERED AND HAS A LOT OF TIME AND SOME TIME BACK WAS TAKEN OUT OF SVC AND HAD EVERY FLAP COMPONENT REPLACED. THE RPTR STATED THE MAIN LNDG GEAR TIRES ARE SPEED RATED FOR 182 MILES PER HR.
