Procedure; Aircraft
Aircraft was dispatched with Bleed System 1 on MEL. We were in icing conditions in cruise flight at FL260 indicating 270 KTS. We were working our way around thunderstorms and had the seatbelt sign on and the flight attendants had been instructed to remain seated due to turbulence. We got an EICAS message indicating a Bleed 2 Leak. As the aircraft could no longer maintain pressurization we immediately descended to 10;000 FT. We completed the QRH procedure. The cabin altitude climbed no higher than approximately 7;700 FT. We used the APU to maintain cabin pressurization and continued on to destination. One bleed system on MEL and second bleed system developed a leak.
EMB190 Captain reports being dispatched with Bleed System 1 on MEL then developing a Bleed System 2 leak. Flight descends to 10;000 FT and uses APU bleed air to continue to destination.
