Narrative:
King 89B GPS, with aug/xa/98-sep/xa/98 data card, flashed 'warning: no data card present -- install card.' turned off GPS, pulled card, reinstalled card, turned on GPS, looked at altitude -- read climbing to 400 ft and climbing. Turned off altitude hold on king 140 autoplt. Display read climbing to 800 ft. Plane climbed to 6800 ft. Disconnected autoplt, descended to assigned altitude. Called ATC to change designation from /G to /U. They said descend to 6000 ft -- plane at 6400 ft. Descended to 6000 ft. Completed flight IFR on VOR and ILS to syr. Scheduled maintenance on 89B king GPS and 140 king autoplt. Flew the plane, called ATC, completed flight using available equipment -- 2 king 155 radios, GS, VOR #2 head, ADF king, transponder. Callback conversation with reporter revealed the following information: reporter stated that since this incident, the manufacturer has replaced the GPS with a new one along with a new data card. During subsequent flts, the equipment has been working as prescribed.

Narrative: KING 89B GPS, WITH AUG/XA/98-SEP/XA/98 DATA CARD, FLASHED 'WARNING: NO DATA CARD PRESENT -- INSTALL CARD.' TURNED OFF GPS, PULLED CARD, REINSTALLED CARD, TURNED ON GPS, LOOKED AT ALT -- READ CLBING TO 400 FT AND CLBING. TURNED OFF ALT HOLD ON KING 140 AUTOPLT. DISPLAY READ CLBING TO 800 FT. PLANE CLBED TO 6800 FT. DISCONNECTED AUTOPLT, DSNDED TO ASSIGNED ALT. CALLED ATC TO CHANGE DESIGNATION FROM /G TO /U. THEY SAID DSND TO 6000 FT -- PLANE AT 6400 FT. DSNDED TO 6000 FT. COMPLETED FLT IFR ON VOR AND ILS TO SYR. SCHEDULED MAINT ON 89B KING GPS AND 140 KING AUTOPLT. FLEW THE PLANE, CALLED ATC, COMPLETED FLT USING AVAILABLE EQUIP -- 2 KING 155 RADIOS, GS, VOR #2 HEAD, ADF KING, XPONDER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT SINCE THIS INCIDENT, THE MANUFACTURER HAS REPLACED THE GPS WITH A NEW ONE ALONG WITH A NEW DATA CARD. DURING SUBSEQUENT FLTS, THE EQUIP HAS BEEN WORKING AS PRESCRIBED.
