Narrative:
Air carrier X at 45 DME from atl; checked in at 14000 ft and was instructed 'runway 28; descend via the HONIE5 arrival.' at 41 DME from atl; tmc changed the assigned runway for air carrier X to runway 26R. At 37 DME from atl; I instructed air carrier X; 'change transition and runway to runway 26R; maintain 14000 ft.' air carrier X appeared to have started a descent already and the mode C indicated 13700 ft; so I instructed; 'air carrier X no problem if you started down already; just climb and maintain 14000 ft. Air carrier X contact atl approach control 128.0.' all these instructions were acknowledged. At 32 DME from atl; I noticed that air carrier X mode C indicated 15000 ft. I called ZTL tiroe sector and advised that air carrier X had apparently climbed to 15000 ft and that he was descending again. I then effected coordination with another controller to tell air carrier X to descend to 14000 ft. Air carrier X was not on his frequency yet; so I broadcast for air carrier X. Air carrier X asked me 'what was that frequency?' I instructed air carrier X to maintain 14000 ft and contact approach 128.0. At 25 DME; air carrier X returned and asked me the frequency again. The pilot called via telephone and said that when he entered the new transition; the RNAV dropped out of the box.

Title: A80 CTLR DESCRIBED PLTDEV EVENT WHEN ACR FAILED TO COMPLY WITH ALT RESTRICTIONS AFTER RWY CHANGE ASSIGNMENT.
Narrative: ACR X AT 45 DME FROM ATL; CHKED IN AT 14000 FT AND WAS INSTRUCTED 'RWY 28; DSND VIA THE HONIE5 ARR.' AT 41 DME FROM ATL; TMC CHANGED THE ASSIGNED RWY FOR ACR X TO RWY 26R. AT 37 DME FROM ATL; I INSTRUCTED ACR X; 'CHANGE TRANSITION AND RWY TO RWY 26R; MAINTAIN 14000 FT.' ACR X APPEARED TO HAVE STARTED A DSCNT ALREADY AND THE MODE C INDICATED 13700 FT; SO I INSTRUCTED; 'ACR X NO PROB IF YOU STARTED DOWN ALREADY; JUST CLB AND MAINTAIN 14000 FT. ACR X CONTACT ATL APCH CTL 128.0.' ALL THESE INSTRUCTIONS WERE ACKNOWLEDGED. AT 32 DME FROM ATL; I NOTICED THAT ACR X MODE C INDICATED 15000 FT. I CALLED ZTL TIROE SECTOR AND ADVISED THAT ACR X HAD APPARENTLY CLBED TO 15000 FT AND THAT HE WAS DSNDING AGAIN. I THEN EFFECTED COORD WITH ANOTHER CTLR TO TELL ACR X TO DSND TO 14000 FT. ACR X WAS NOT ON HIS FREQ YET; SO I BROADCAST FOR ACR X. ACR X ASKED ME 'WHAT WAS THAT FREQ?' I INSTRUCTED ACR X TO MAINTAIN 14000 FT AND CONTACT APCH 128.0. AT 25 DME; ACR X RETURNED AND ASKED ME THE FREQ AGAIN. THE PLT CALLED VIA TELEPHONE AND SAID THAT WHEN HE ENTERED THE NEW TRANSITION; THE RNAV DROPPED OUT OF THE BOX.
