Metro (SW4) question

[swh]

Anyone guess what these guys would be doing to the engine ?

I would guess they are balancing the props. Appears to be some leads going into the emergency exit from the engine. The object on the top cowl is probably a photocell which detects blade position and RPM.
You cant drive metros with the main door opened.

Could it be trimming the FCU?

Seen it done before on 737's with wires out of the emergency exit onto the engine.

Just a guess.

That's a prop balance happening right there!
