Karen BollingerAfter a “WIND” day yesterday, we left Brandon, Manitoba, en route to Regina, Saskatchewan. N758F was fresh out of a 100–hr inspection, including a change-out of the alternator to a spare rebuilt one.

Half way to our first survey segment, the alternator quit functioning. After shutting down all non-essential electrical instruments, we flew the two air-grounds (upon which the ground crew was waiting for us) and 2 other segments before landing at Regina. Inspection showed that actually the alternator belt had broken, rather than the alternator actually failing. By using some innovation and working with the mechanics (Roger and Tony) at Shell Aerocentre, we were able to get the belt replaced and N758F ready for flying the next day.
