Just wanted to complain

GA guys, do you ever get tired of having crap break on you then learning that it's the same crap that's been breaking in the same ways for 20 years, and manufacturers still haven't fixed it? Makes me want to spam SDRs.
 
Just little stuff here and there. I mean for example you'd think that by this point they'd have magnetos pretty well figured out, but we've seen a removal rate as much as 25% before normally scheduled maintenance.

They have drop in electronic breaker point eliminators for old cars, seems like we could, you know, have the same thing.

I pulled a mag at 4.2 hours since new because the points failed, found the point spring in the bottom of the mag.

This, to me, is not acceptable.

Well the feds could also pull their heads out of their ass and let us go to digital ignition. Since things that move a lot tend to fail a lot more than things that don't move at all.

Oh absolutely. On a turbo motor that can easily run near detonation having a brain to vary timing would be much safer anyway. Otoh with the quality control I see from piston OEMs even going to electronic doesn't necessarily give me warm fuzzies.

The one's available for the experimental market have a fantastic safety record. All of the systems I've looked at have real world MTBF well past the life of any piston engine.
Couple that with EFI and you have IO-360's putting out 250+hp running cooler CHTs and burning a lot less fuel.

Fair enough, but let kelly aerospace make it and I'm sure your MTBF will drop drastically.
 
Having seen an ELT 'battery' I'm not surprised.

Bent Cowl flaps was one I saw fairly often too.
 
The other thing that pisses me off is the inane things we have ADs for vs the other stuff that has trails of SDRs decades long that there is no AD and therefore no push for the manufacturers to improve the product.
 
There is an electronic ignition in the STC market. Spencer Suderman did the R&D on his Pitts for the -540 approval.

The IO-240F on the Liberty XL-2 has FADEC for ignition and fuel yet it was the biggest hangar queen I've ever worked on. The 2.2L in my last Accord went 320,000 miles without any engine problems, and it did it without a TCDS or a single piece with FAA-PMA on it.

Ya there's quite a few, but you still have to keep a magneto in every installation I've seen, which negates almost all of the advantages. Fixed timing is the biggest problem.
