Overhead vents

[tls pilot]

It seems one of the overhead vents in my friends Bravo has no air coming out

but the other forward vent and two rear vents work fine

is there separate connection on each eyeball?

This is in a NON air-condition plane, just vent air

 

Any suggestions how to fix? His is an older Bravo without the middle overhead switches

How can it be repaired?

 

Thank you

 

Thanks

There are separate hoses feeding each eyeball vent.  He'll have to drop the headliner to trouble-shoot, but it is likely an easy fix.

Taking the headliner down will not be easy either

I used the new Gee Bee hoses.  The overhead ducts had holes in them and everything under the panel was split and corroded. If you are interested in doing the overhead ducts DM me as I learned a few things along the way. The quality of the new ducts are outstanding.

If you have one, stick a borescope into the vent. You might find a small insect nest blocking the duct path or a disconnected tube. Hope it all worked out!
