Narrative:
Normal touchdown using flaps 28 degrees, winds 170 degrees/13 KTS gusting 20 KTS, throttles approximately one knob width above idle at touchdown. Spoilers deployed normally but seemed to bounce off the aft stop and fully retracted. Spoilers were then deployed manually. Remainder of landing was uneventful. Callback conversation with reporter revealed the following information: the reporter stated the airplane was landed smoothly with the thrust levers slightly above normal idle. The reporter said the ground spoilers deployed normally then immediately retracted disarming the autobraking system. The reporter stated a log entry was made and the ground spoiler system was ground checked per the maintenance manual and found ok by maintenance.
Original NASA ASRS Text
Title: AN MD80 ON NORMAL LNDG GND SPOILERS DEPLOYED THEN IMMEDIATELY RETRACTED. THROTTLE POS SLIGHTLY ABOVE IDLE. SPOILERS DEPLOYED MANUALLY.
Narrative: NORMAL TOUCHDOWN USING FLAPS 28 DEGS, WINDS 170 DEGS/13 KTS GUSTING 20 KTS, THROTTLES APPROX ONE KNOB WIDTH ABOVE IDLE AT TOUCHDOWN. SPOILERS DEPLOYED NORMALLY BUT SEEMED TO BOUNCE OFF THE AFT STOP AND FULLY RETRACTED. SPOILERS WERE THEN DEPLOYED MANUALLY. REMAINDER OF LNDG WAS UNEVENTFUL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE AIRPLANE WAS LANDED SMOOTHLY WITH THE THRUST LEVERS SLIGHTLY ABOVE NORMAL IDLE. THE RPTR SAID THE GND SPOILERS DEPLOYED NORMALLY THEN IMMEDIATELY RETRACTED DISARMING THE AUTOBRAKING SYS. THE RPTR STATED A LOG ENTRY WAS MADE AND THE GND SPOILER SYS WAS GND CHKED PER THE MAINT MANUAL AND FOUND OK BY MAINT.
