Champion Slick Magnetos

A most recent popular topic has been (Champion) Slick Magnetos.

Q:  Is there an AD requiring a 500 hour overhaul?

A:  No.  Most shops “require” one, imposed by their own standards, and those of the manufacturer.  There is no AD requiring a 500-hour overhaul on Slick magnetos.

Q:  Is there any documentation to reference the overhaul?

A:  Yes.  Champion has issued 2 Service Bulletins:  SB1-15 and SB 1-15A.

SB1-15 makes reference to a 500-hour time-in-service warranty period, however SB1-15A makes no reference to the 500 hours.  Be sure to read both documents slowly and carefully.

Q:  Why doesn’t Zook Aviation include this SB in the AD Toolbox?

A:  Every service document (Bulletin, Letter, Alert, etc) must be directly AD-Referenced for us to include it on our site.  Since there is no AD for the 500-hour overhaul, we have no method to attach the Service Bulletin.  So, we’ve included it here on our blog for your convenience.
