Actually, it is the contactor that distributes all ac power. Power from the external plug, the IDG's and the APU gen all go through this contactor. It's the thing that clanks when you throw the gen's on or off line. So, yeah, it is a good thing that it didn't happen in flight. Because it it not isolated to ground use equipment is why the NTSB jumped all over this.

Didn't ASA also have some ground power relay catch fire after getting wet a few years back??

I don't recall that one?

They had carbon build up between two gens from water that leaked into the avionics bay.

I don’t know what failed, but there are several (6) large contactors in that box to distribute power from the four potential power sources to the aircraft. Both engine generators and the APU generator are monitored for over current. External power is not. If I were to speculate, I’d say this is the contributing factor.
 
If that thing isn't a total loss, I'm sure it's gonna smell great once they get it put back togeather and overhauled. Mmmmmm, the smell of electrical smoke and burnt plastic- how nice!


The rumor is that they've found a new wire bundle and that they are planning on putting the plane back together and back in service.

I don't wanna be the first to fly that plane.
 
Is it still in TLH or did they fly it back unpressurized


The hole is the smallest of the problems. The real problem is that every system associated with Panel 1 is disabled. Plus every wire bundle over the crown of the aircraft most likely has heat damage. Most wire bundles like this run the entire length of the aircraft. This aircraft will need the entire interior replaced. Add up all the work and the fact it was one of our first RJ's and I'd have to say it's worth more in parts and beer cans.

two words: wire splice.

you'd be shocked how much damage can be repaired and fly the plane away.
