 |

Hi Guys,
I visited the hangar to do a preflight this afternoon and a friend found my Stratus solid state ignition bracket was cracked and there was a lot of flex in it.
Two 8.8 mm bolts holding the rectangular box to the engine were the only thing keeping it from dropping off. I loosened the bolts and removed the bracket
in two pieces. The .080 steel bracket would have been stout enough, but the bolted flanges were cut square and cracks began there. I removed the
safety wire and electric connections and took the bracket home. I remade an .080 bracket that has no corners or sharp edges. I put some high temp silver paint on it
and hung it out for reassembly tomorrow. I think I’m probably the 10th person that has had this bracket crack in this way. Time to look carefully at yours, especially
if you have but one ignition.
Fly safe guys,

Thanks for the warning, Larry. I'll look at mine tomorrow, when I'm reinstalling my primary ignition.

When I was building my plane I didn't like the way the ignition was mounted. My concern is that the cantilevered mounting can let the module vibrate. What I did was to put a plastic threaded pipe plug in a threaded hole under the module. This keeps the module and bracket in tension so it cannot vibrate. So far 150 hours and no cracks.
