Narrative:

An A320 was dispatched with an MEL engine #2 anti-ice valve stuck open. Had to do a full thrust, bleeds off, thrust bump takeoff for performance requirements. Had to reject takeoff at 120 KTS (V1 at 153) due to #2 engine overtemp (642 degrees C -- maximum is 635 degrees C). Autobrakes rejected takeoff feature engaged and aircraft decelerated quickly. Brake temperatures got as hot as 830 degrees C. Maintenance advised us to proceed to gate with brake fans running and do not set parking brake at gate. Upon arrival at gate, all 4 mains deflated because of high temperature fuse plugs. Maintenance came on and was not surprised it overtemped because the airplane had had '3 previous overtemps on takeoff prior in the day.' (all were at or after V1, so all flts continued to destination). After hearing this, I went back 5-6 pages in logbook and discovered the previous overtemps -- all were inspected at destination per the airbus maintenance manual -- or so they said. Had I known aircraft had a history of overtemping, I may have elected not to take aircraft on such a high thrust takeoff with high outside air temperatures. Furthermore, I cannot believe this aircraft was not taken OTS for further inspection after second overtemp in a day. Obviously, a contributing factor was our MEL causing #2 anti-ice valve to be stuck open. But the MEL specifically requires 'full thrust takeoffs must be made.' and there is no prohibitions on thrust bump usage in MEL. Corrective actions suggested: 1) provide crews with a minimum of 3 days aircraft maintenance history with release so that we can determine if any 'pencil whipping' is going on in maintenance. (This should be easy with today's technology.) this should be mandatory and not on a 'requested basis of crew.' 2) I can see an occasional overtemp on engine when operating in outside air temperatures of +100 degrees that we normally operate in phx a and las, but second overtemp should have grounded aircraft immediately for further engine/bleed analysis. 3) perhaps MEL concerning engine anti-ice valve stuck open should be readdressed to contain limitations on maximum outside air temperatures for takeoff and no thrust bumps allowed while operating under the MEL provisions. 4) increase training on how to handle such hot brakes on a rejected takeoff, ie, what temperatures do tire fuse plugs blow? What temperatures should we consider calling fire equipment, etc?

Title: AN A320 HAS A HIGH SPD ABORT FOR AN ENG OVERTEMP. ENG ANTI-ICE BLEED WAS DEFERRED INOP OPEN. 4 TIRES GO FLAT AFTER RETURN TO THE GATE.

Narrative: AN A320 WAS DISPATCHED WITH AN MEL ENG #2 ANTI-ICE VALVE STUCK OPEN. HAD TO DO A FULL THRUST, BLEEDS OFF, THRUST BUMP TKOF FOR PERFORMANCE REQUIREMENTS. HAD TO REJECT TKOF AT 120 KTS (V1 AT 153) DUE TO #2 ENG OVERTEMP (642 DEGS C -- MAX IS 635 DEGS C). AUTOBRAKES REJECTED TKOF FEATURE ENGAGED AND ACFT DECELERATED QUICKLY. BRAKE TEMPS GOT AS HOT AS 830 DEGS C. MAINT ADVISED US TO PROCEED TO GATE WITH BRAKE FANS RUNNING AND DO NOT SET PARKING BRAKE AT GATE. UPON ARR AT GATE, ALL 4 MAINS DEFLATED BECAUSE OF HIGH TEMP FUSE PLUGS. MAINT CAME ON AND WAS NOT SURPRISED IT OVERTEMPED BECAUSE THE AIRPLANE HAD HAD '3 PREVIOUS OVERTEMPS ON TKOF PRIOR IN THE DAY.' (ALL WERE AT OR AFTER V1, SO ALL FLTS CONTINUED TO DEST). AFTER HEARING THIS, I WENT BACK 5-6 PAGES IN LOGBOOK AND DISCOVERED THE PREVIOUS OVERTEMPS -- ALL WERE INSPECTED AT DEST PER THE AIRBUS MAINT MANUAL -- OR SO THEY SAID. HAD I KNOWN ACFT HAD A HISTORY OF OVERTEMPING, I MAY HAVE ELECTED NOT TO TAKE ACFT ON SUCH A HIGH THRUST TKOF WITH HIGH OUTSIDE AIR TEMPS. FURTHERMORE, I CANNOT BELIEVE THIS ACFT WAS NOT TAKEN OTS FOR FURTHER INSPECTION AFTER SECOND OVERTEMP IN A DAY. OBVIOUSLY, A CONTRIBUTING FACTOR WAS OUR MEL CAUSING #2 ANTI-ICE VALVE TO BE STUCK OPEN. BUT THE MEL SPECIFICALLY REQUIRES 'FULL THRUST TKOFS MUST BE MADE.' AND THERE IS NO PROHIBITIONS ON THRUST BUMP USAGE IN MEL. CORRECTIVE ACTIONS SUGGESTED: 1) PROVIDE CREWS WITH A MINIMUM OF 3 DAYS ACFT MAINT HISTORY WITH RELEASE SO THAT WE CAN DETERMINE IF ANY 'PENCIL WHIPPING' IS GOING ON IN MAINT. (THIS SHOULD BE EASY WITH TODAY'S TECHNOLOGY.) THIS SHOULD BE MANDATORY AND NOT ON A 'REQUESTED BASIS OF CREW.' 2) I CAN SEE AN OCCASIONAL OVERTEMP ON ENG WHEN OPERATING IN OUTSIDE AIR TEMPS OF +100 DEGS THAT WE NORMALLY OPERATE IN PHX A AND LAS, BUT SECOND OVERTEMP SHOULD HAVE GNDED ACFT IMMEDIATELY FOR FURTHER ENG/BLEED ANALYSIS. 3) PERHAPS MEL CONCERNING ENG ANTI-ICE VALVE STUCK OPEN SHOULD BE READDRESSED TO CONTAIN LIMITATIONS ON MAX OUTSIDE AIR TEMPS FOR TKOF AND NO THRUST BUMPS ALLOWED WHILE OPERATING UNDER THE MEL PROVISIONS. 4) INCREASE TRAINING ON HOW TO HANDLE SUCH HOT BRAKES ON A REJECTED TKOF, IE, WHAT TEMPS DO TIRE FUSE PLUGS BLOW? WHAT TEMPS SHOULD WE CONSIDER CALLING FIRE EQUIP, ETC?
