OK. . . this is going to sound weird. . . but the technological marvel of the DA42. . . you'd assume there would be only circuit breakers and no fuses, but I found at least 4 circuits which, per the maintenance manual, have fuses in them. There is even a diagram showing the fuse for one of them - so its not just that they used the word "fuse" incorrectly and really meant "circuit breaker".

1. The hot bus (20 amp)
2. The landing gear (50 amp)
3. The excitation battery
4. The "glow" fuse

Now. . . I learned way back that if you want to fly at night you have to have spare fuses accessible to the pilot in flight (91.205 (c)(6)).

Is there an "out" somewhere that allows these airplanes to fly without spare fuses? e.g. the fact that the fuses are installed where the pilot could not reach / change the fuse in flight?
