Had a non genuine voltage regulator (owner/operator modification) fail on a return trip from Arkaroola to the not quite so remote home base in Day VMC conditions. (No GPS back n those days.)
It fried everything, Nav/Comms, the T+B anything that was connected to the bus board. It was only at around 50 feet on the upwind leg on climb (sort of) during a hot (38 C) afternoon. I was slow to switch the master off as the flaps still needed to be raised (and that first 2-3 seconds of panic in an emergengy is real)
. The fully loaded 206 did have a serviceable Vac pump and the AH was working.
That would have been the only thing that would have saved my ar#e if it had happened the day before when I departed an hour before first light (solo) on a charter / pick up. I only had the the hurricane lamps to light the strip and it would have been an interesting morning as there was only the smallest bit of moonlight and no other hint of a horizon outside.
The stupid things we do when we have a fresh CPL and think we are invincible.
