Welp our flap motor has gave up the ghost. Anyone know where to source a replacement motor or a shop that overhauls these things? My mechanic and I are coming up short on finding anything in the salvage world much less new old stock.

Looks to be P/N C301002-0104
 
Make sure the fault is not in the travel limit microswitches, or at the flap control, which also uses microswitches
The switches on the plap actuator get oil or grease in them from incorrect lube procedures. The switches under the panel can sometimes break or get out of rig.
 
I agree with Dan that you want to check everything prior to shotgunning a motor. However if you do need one, checking that P/N on Textron indicates it is superseded to C301002-0121 which is available (319 in stock)
 
Just an FYI...McFarlane has PMA'd this part. They are preparing for shipment and available for pre-order now. Increases in reliability and lower price.

A local electric motor shop rebuilt a non-working flap motor for hanger mate couple of years ago for less than $200 . Still working today... maybe check your area and see if your A&P good with it. Most old school shops should be able to do most required work.

The OP's post about this was in February 2024. I think he probably has the system fixed. I wish POAers would update us as to what the final findings and solutions were. We could all learn something if they would just come back and tell us about it.
