Came off IO-360. It's the 4300 and 6300 series mags. Ours was 4371 but a bunch use the same impulse couplings. The rivets get loose

We have had 1 mag fail and it took a tooth off the gear. All the new impulse couplings we are getting the rivets are coming loose within hours. The last one we pulled was 50 hours old. They have an SB 2-19A to inspect them and we are finding all new parts are horrible. Anyone else have this issue?

Stevenson aviation in Southport Manitoba has a 9 week a year for 4 years and if u pass the government pays the tuition. It's a great program
