Hi all,

I'm Eric and currently working in aviation industry as an aircraft mechanic. I joined this forum because I think i can get some help or tips when I'm having troubles with the KA E90 that I'm maintaining.

Welcome. Someone will come along that can give you advise I’m sure. What are the issues? Airframe or engine?

Thank you for the warm welcome. I'm having an issue with my air conditioning system. What happens is when I turn the selector in auto, the condenser blower wont turn on when its normally turn on when I put in auto. But it works in manual cool. But after our last flight, the blower won't turn off even the selector is in the off position.And there's no way for us to turn it off except by unplugging the power source or ground of the blower because there's no CB inside the cabin for it and we cannot start the engines with the blower turned on that's why I unplugged it because we don't have a ground power unit and the blower draws a lot of voltage from the battery.

Hi Enrico, welcome to BT.
Might be better to post your question in the Turbine forum.

Best,
John

Hi john, thank you for the idea.
