I have a 2200 A, serial number 22A 981. The stator gear broke in two and I'd like to know if this part is still available through Arion Aircraft in the US? The part number is 4776494. I attached a photo for reference.
Unless Arion have a used starter that they can take the rotor out of, I don't think they will have a replacement part.
However the later starter and gearbox is compatible with the pinion housing you have. The bonus is that the later starter has more power.
