Narrative:
On selecting slats and flaps for VFR night approach to alb, we did not get the required blue slat extended light, and also got a slat disagreement annunciator light. After referring to my air carrier's operating procedures manual, it was determined we would make our approach and landing using flaps only and no slats. During our delayed vectors for approach and while performing procedures we did not experience any rolling or control wheel out of center position. After conferring with company dispatch and allowing for a slightly increased vref and approach speeds (including any extra runway needed for procedure) it was determined that alb was still allowable to land runway 19. A normal landing was made stopping in less than 4000 ft on a dry, calm wind runway. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was a DC9-50 and the maintenance action required to correct the leading edge device malfunction is unknown as the reporter did not fly the aircraft the next morning.

Title: A DC9-50 ON APCH AT 3000 FT HAD THE LEADING EDGE DEVICES FAIL TO EXTEND AND REQUIRED LNDG WITH THE TRAILING EDGE FLAPS ONLY.
Narrative: ON SELECTING SLATS AND FLAPS FOR VFR NIGHT APCH TO ALB, WE DID NOT GET THE REQUIRED BLUE SLAT EXTENDED LIGHT, AND ALSO GOT A SLAT DISAGREEMENT ANNUNCIATOR LIGHT. AFTER REFERRING TO MY ACR'S OPERATING PROCS MANUAL, IT WAS DETERMINED WE WOULD MAKE OUR APCH AND LNDG USING FLAPS ONLY AND NO SLATS. DURING OUR DELAYED VECTORS FOR APCH AND WHILE PERFORMING PROCS WE DID NOT EXPERIENCE ANY ROLLING OR CTL WHEEL OUT OF CTR POS. AFTER CONFERRING WITH COMPANY DISPATCH AND ALLOWING FOR A SLIGHTLY INCREASED VREF AND APCH SPDS (INCLUDING ANY EXTRA RWY NEEDED FOR PROC) IT WAS DETERMINED THAT ALB WAS STILL ALLOWABLE TO LAND RWY 19. A NORMAL LNDG WAS MADE STOPPING IN LESS THAN 4000 FT ON A DRY, CALM WIND RWY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS A DC9-50 AND THE MAINT ACTION REQUIRED TO CORRECT THE LEADING EDGE DEVICE MALFUNCTION IS UNKNOWN AS THE RPTR DID NOT FLY THE ACFT THE NEXT MORNING.
