Field Approval for B&C Specialty Technology back up alternator

[Oscar Avalle]

Because I went full electrial (electronic magnetos and instruments) I never felt confortable not having a second alternator in my M20C (E). So I came through B&C back up alternators. They had been approved for PA32 and for Bonanzas.

I decided to look at the unit and with my IA and AP we did the installation and got the field approval for the system.

The unit work flawlessly and it lowers my anxiety... the stand by battery never provided me with the necessary state of mind.

Nice success story!  Who says you can't get field approvals?

Did the same on my O. Love it. Field Approval was straightforward since it’s the same engine as the Bo.
