RE: Flameout problem
Thanks for the responses guys - I'm off to the field now.
I think the best strategy is to try one thing at a time. I will take the filter out and see how that effects things and have taken the filter from my Jetcat with me to try.
I will also change the turbine battery if that doesn't work and will eventually change the UAT if all else fails. I was assuming any fault was happening downstream of the UAT but will start looking further up if the problem persists.
There has been no smoke with these flameouts - I've always had guys with me when these have happened and no one has noticed anything.
Thanks for all the speedy responses.
