Narrative:

We were being vectored for runway 27L into ZZZ. At 8000 ft and 210 KTS; the first officer requested flaps 1 and 8. At that time we got a slats fail caution message. The flaps would not deploy as well. I asked for vectors so that we could perform the aom procedures. After we completed the procedures outlined in the aom; we were able to get the flaps to work; but not the leading edge slats. I briefed the flight attendants and passenger; called maintenance; declared an emergency and landed safely. The passenger were calm when they exited the aircraft. I'm not sure why we got the slats fail message. There are way too many mels in the crj. It seems to me that most of the mels and problems in the crj are not fixed; they end up operations checking good.callback conversation with reporter revealed the following information: the reporter stated after being vectored to perform the operating manual procedures for slat and flap failure; the trailing edge flaps began operating; but the leading edge slats remained failed. The landing was uneventful. The reporter indicated that maintenance did not remove this airplane from service; but reracked the flap slat control unit and returned the airplane to service where it failed two more times with the same report.

Original NASA ASRS Text

Title: A CRJ700 ON APCH AT 8000 FT DECLARED AN EMER DUE TO SLAT EXTENSION FAILURE; AND RECEIVED TRAILING EDGE FLAPS WITH SLATS FAIL MESSAGE. AOM PROCS PERFORMED AND TRAILING EDGE FLAPS RECOVERED. LANDED UNEVENTFULLY.

Narrative: WE WERE BEING VECTORED FOR RWY 27L INTO ZZZ. AT 8000 FT AND 210 KTS; THE FO REQUESTED FLAPS 1 AND 8. AT THAT TIME WE GOT A SLATS FAIL CAUTION MESSAGE. THE FLAPS WOULD NOT DEPLOY AS WELL. I ASKED FOR VECTORS SO THAT WE COULD PERFORM THE AOM PROCS. AFTER WE COMPLETED THE PROCS OUTLINED IN THE AOM; WE WERE ABLE TO GET THE FLAPS TO WORK; BUT NOT THE LEADING EDGE SLATS. I BRIEFED THE FLT ATTENDANTS AND PAX; CALLED MAINT; DECLARED AN EMER AND LANDED SAFELY. THE PAX WERE CALM WHEN THEY EXITED THE ACFT. I'M NOT SURE WHY WE GOT THE SLATS FAIL MESSAGE. THERE ARE WAY TOO MANY MELS IN THE CRJ. IT SEEMS TO ME THAT MOST OF THE MELS AND PROBLEMS IN THE CRJ ARE NOT FIXED; THEY END UP OPS CHKING GOOD.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED AFTER BEING VECTORED TO PERFORM THE OPERATING MANUAL PROCS FOR SLAT AND FLAP FAILURE; THE TRAILING EDGE FLAPS BEGAN OPERATING; BUT THE LEADING EDGE SLATS REMAINED FAILED. THE LNDG WAS UNEVENTFUL. THE RPTR INDICATED THAT MAINT DID NOT REMOVE THIS AIRPLANE FROM SVC; BUT RERACKED THE FLAP SLAT CTL UNIT AND RETURNED THE AIRPLANE TO SVC WHERE IT FAILED TWO MORE TIMES WITH THE SAME RPT.
