Narrative:

Since I wasn't there; I can only assume that 1) someone failed to adjust the slat system according to the manual and 2) the inspector failed to catch the mistake. Aircraft had recently come out of c-chk. While there; they had worked on some components of the slat system. A pilot noticed that the slats did not seem to be retracted all the way; so he wrote them up and the plane was ferried to ZZZ. Upon arrival we noticed that there were no messages associated with a slat fault; but the slats did not appear to be fully retracted. We performed an electrical rig check and found that the slats were out of mechanical rig. The clearance that we were supposed to have was a gap between the stop bolt and a through bolt of .080 inches +/-.005 inches. When we checked it; it was approximately .250 inches; nearly half a turn on the torque tubes and almost a half inch of slat travel. This fault is an obvious lapse of quality control on the part of aircraft maintenance facility. A keen-eyed pilot noticed the discrepancy. Once we found the problem we adjusted the slats in accordance with the book and everything looked and operated normally. We have seen several aircraft come out of c-chk needing a lot of work/troubleshooting. The quality of work that comes out leaves a lot to be desired. I recommend looking into switching locations.

Title: A CL-600 (CRJ-700) ACFT SLAT SYSTEM WAS FOUND TO BE OUT OF RIG AFTER BEING RELEASED FROM A CONTRACT MAINT 'C' CHK. ACFT FERRIED TO MAINT BASE.

Narrative: SINCE I WASN'T THERE; I CAN ONLY ASSUME THAT 1) SOMEONE FAILED TO ADJUST THE SLAT SYS ACCORDING TO THE MANUAL AND 2) THE INSPECTOR FAILED TO CATCH THE MISTAKE. ACFT HAD RECENTLY COME OUT OF C-CHK. WHILE THERE; THEY HAD WORKED ON SOME COMPONENTS OF THE SLAT SYS. A PLT NOTICED THAT THE SLATS DID NOT SEEM TO BE RETRACTED ALL THE WAY; SO HE WROTE THEM UP AND THE PLANE WAS FERRIED TO ZZZ. UPON ARR WE NOTICED THAT THERE WERE NO MESSAGES ASSOCIATED WITH A SLAT FAULT; BUT THE SLATS DID NOT APPEAR TO BE FULLY RETRACTED. WE PERFORMED AN ELECTRICAL RIG CHK AND FOUND THAT THE SLATS WERE OUT OF MECHANICAL RIG. THE CLRNC THAT WE WERE SUPPOSED TO HAVE WAS A GAP BTWN THE STOP BOLT AND A THROUGH BOLT OF .080 INCHES +/-.005 INCHES. WHEN WE CHKED IT; IT WAS APPROX .250 INCHES; NEARLY HALF A TURN ON THE TORQUE TUBES AND ALMOST A HALF INCH OF SLAT TRAVEL. THIS FAULT IS AN OBVIOUS LAPSE OF QUALITY CTL ON THE PART OF ACFT MAINT FACILITY. A KEEN-EYED PLT NOTICED THE DISCREPANCY. ONCE WE FOUND THE PROB WE ADJUSTED THE SLATS IN ACCORDANCE WITH THE BOOK AND EVERYTHING LOOKED AND OPERATED NORMALLY. WE HAVE SEEN SEVERAL ACFT COME OUT OF C-CHK NEEDING A LOT OF WORK/TROUBLESHOOTING. THE QUALITY OF WORK THAT COMES OUT LEAVES A LOT TO BE DESIRED. I RECOMMEND LOOKING INTO SWITCHING LOCATIONS.
