Magnetos

[jchronic]

Just sitting here I can't cite the reference without looking it up, but in my case - operating in compliance with Part 135 rules (terms of my survey contract) - my mags (Bendix) come off for inspection (IRAN) every 500 hours. May not apply under Part 91; again, unsure whether it's a recommendation or an actual AD....

Recommended for Part 91, not required

[JB78382]

Under Part 91 it is recommended, the TCM I.O. 360 owners manual says Bendix mags "should" or "need" to be overhauled at 500 hr interval.

Whats the cost of overhauling a mag vs installing an electronic ignition?

$750 to $1000 in most cases. Electroaire are in the $3000 range

Surefly is another certified option to replace 1 magneto. Need a slick harness and engine analyzer. $1695 per.

Surefly seems like they intend to put Electroaire out of business.

$1695 vs. $4400? I just checked, those are the current prices for a Cont. 360 setup.

And the install is much simpler with the SureFly, it just replaces the existing mag (after adding a power circuit), whereas the ElectroAire requires the additional installation of a magnetic crank position sensor.

Hello. I'm pretty sure the 500 Hour is an INSPECTION not an OVERHAUL, especially under the Part 91. Your local A&P mechanic can do the inspection without much trouble. Although the mags are difficult to remove/install, time consuming maybe 6-8 hours total. Especially if the A&P hasn't have much Skymaster maintenance time. Hope this helps.
Regards.
