Narrative:

On climb out, I noticed engine #1 internal turbine temperature rising, leaving 16000 ft. I monitored this and asked first officer to look in our aircraft operating manual for a checklist for rising internal turbine temperature. Only a checklist for exceeding internal turbine temperature limit is available. Internal turbine temperature limit for 'maximum continuous' is 901 degrees. #1 reached 878 degrees when I decided to level at FL200. #2 internal turbine temperature was 775 degrees. I reduced thrust to stay below vmo -- internal turbine temperature dropped. We recycled #1 bleed valve and pack valve. No changes. I called dispatch and maintenance control. They advised me to cycle bleed valve again. No changes. I asked maintenance control to observe engines and temperatures via ACARS. They confirmed high internal turbine temperature on #1. I entered internal turbine temperature temperatures in the logbook/write-up and an engine trend monitoring entry was done also. Mechanic in ZZZ told me that they could only ground run the engine since no limits were exceeded. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was an embraer 145 with allison AE3007A engines. The reporter said the cause of the high turbine temperature was a failed open engine bleed valve. The reporter said he was upset that the maintenance technician advised the crew nothing could be done unless the engine exceeded the limit. The reporter stated maintenance should have recognized a bleed problem immediately.

Title: AN EMBRAER 145 AT LEVELOFF AT FL200 WAS REQUIRED TO REDUCE THRUST ON #1 ENG DUE TO HIGH TURBINE TEMP CAUSED BY A FAILED OPEN BLEED VALVE.

Narrative: ON CLBOUT, I NOTICED ENG #1 INTERNAL TURBINE TEMP RISING, LEAVING 16000 FT. I MONITORED THIS AND ASKED FO TO LOOK IN OUR ACFT OPERATING MANUAL FOR A CHKLIST FOR RISING INTERNAL TURBINE TEMP. ONLY A CHKLIST FOR EXCEEDING INTERNAL TURBINE TEMP LIMIT IS AVAILABLE. INTERNAL TURBINE TEMP LIMIT FOR 'MAX CONTINUOUS' IS 901 DEGS. #1 REACHED 878 DEGS WHEN I DECIDED TO LEVEL AT FL200. #2 INTERNAL TURBINE TEMP WAS 775 DEGS. I REDUCED THRUST TO STAY BELOW VMO -- INTERNAL TURBINE TEMP DROPPED. WE RECYCLED #1 BLEED VALVE AND PACK VALVE. NO CHANGES. I CALLED DISPATCH AND MAINT CTL. THEY ADVISED ME TO CYCLE BLEED VALVE AGAIN. NO CHANGES. I ASKED MAINT CTL TO OBSERVE ENGS AND TEMPS VIA ACARS. THEY CONFIRMED HIGH INTERNAL TURBINE TEMP ON #1. I ENTERED INTERNAL TURBINE TEMP TEMPS IN THE LOGBOOK/WRITE-UP AND AN ENG TREND MONITORING ENTRY WAS DONE ALSO. MECH IN ZZZ TOLD ME THAT THEY COULD ONLY GND RUN THE ENG SINCE NO LIMITS WERE EXCEEDED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS AN EMBRAER 145 WITH ALLISON AE3007A ENGS. THE RPTR SAID THE CAUSE OF THE HIGH TURBINE TEMP WAS A FAILED OPEN ENG BLEED VALVE. THE RPTR SAID HE WAS UPSET THAT THE MAINT TECHNICIAN ADVISED THE CREW NOTHING COULD BE DONE UNLESS THE ENG EXCEEDED THE LIMIT. THE RPTR STATED MAINT SHOULD HAVE RECOGNIZED A BLEED PROB IMMEDIATELY.
