(Moderator note: because it involves equipment common to RV's, this is RV-related.)
My son has helped build several RV's during his A@P apprenticeship.
Last Tuesday, a Cirrus 22 dead sticked to my airport from 19,000' on a cross country. He tried switching tanks, fuel pump on, to no avail. Fortunately, my stepson is a Cirrus trained A@P. He came home from work and diagnosed it as DUAL mag failure!
The plastic gears had stripped on both mags. The driving gears in the accessory section operated smoothly.
He had two mags overnighted and installed them the next day. The engine fired up on the second blade, ran fine and they test flew it and the gent went home to Tampa.
The airplane has a 4 bladed composite MT prop and the thinking is that there is not much vibration damping and could be a causative factor.
The engine parameters were downloaded to a memory stick and forwarded to Cirrus for examination to try and get to the root of this, since they only had 200 hours on them and the factory rebuilt IO-550.
Amazing,
