Avionics Buss Remote Reset Cirucuit Breaker
« on: November 07, 2017, 12:41:49 pm »
The #2 Avionics Buss on my airplane has, on an intermittent basis, been coming on with the battery switch.  After consulting with Twin Commander Tech Support and viewing the actual Rockwell wiring diagram for my aircraft, the best guess is the 6141H82 Remote Reset Circuit Breaker in the aft junction box is sticking.  The only replacement part I have been able to locate is a 'salvage' part, removed from an aircraft being parted out.  I have found a 'replacement' part, an electronic version manufactured by Eaton, p/n M82283/02-09  It is not, however an 'official' FAA Approved replacement part.

Has anyone else had this issue?  If so, how was it resolved?

If the breaker has the same characteristics of the original I would not hesitate to replace it.  I am not totally up to speed on the whole (if you can't buy it anymore ) process but at some point you just can't get replacement parts and very few of those original parts have pixie dust in them any more so at some point you have to replace them.  And I'm sure not going to junk an airplane over a circuit breaker. :-)

just my 2 cents,

Thanks.  I have had some further discussions with Twin Commander.  The 6141H82 relay was 'crossed' to a 6141H172 Relay.  Those are also obsolete and 'out of production', but I have managed to locate a 'serviceable' unit that will come with an 8130 form. Twin Commander approved the use of the H172 relay, so a serviceable unit is an 'FAA Legal' part to put into the airplane.   

Twin Commander Tech Support is also looking at the 'cross' for the 6141H172 relay, the 6041H217 relay, which is in fact currently in production.  As the Type Certificate holder, should they agree, then that unit would be an 'FAA Legal' part to use.

Use of anything else would 'legally' require approval from an electrical DER.
