What is the latest on carb floats?

in 912 / 914 Technical Questions 7 years ago
I was thrilled today to pull my float bowls for my condition inspection only to find one float trying to be a submarine! What's the word on the street with these floats? The new aircraft next door from me is down with a different float issue! I don't have a warm fuzzy feeling that the replacements are of better quality? I guess the good thing was my aircraft never gave me any issues in flight .

    Update on my issue! Just called Lockwood and no floats available at this time! What is going on! Unacceptable in my book! No date given on when new style floats will be available!

    There isn’t really anything new to report on floats right now.
    As per the current Line Maintenance Manual, floats should always be inspected and weighed at every annual inspection.

    Late 2014 there was a Service Bulletin release requiring immediate inspection of floats for a certain range of affected floats. ( See the blog post http://www.rotax-owner.com/en/rotax-blog/item/34-912-914-float-inspection ).

    Subsequently, last year a second bulletin was released, focusing on a range of newer float production that was suspect. (See the blog post http://www.rotax-owner.com/en/rotax-blog/item/48-2016-floats)

    Roger,
    Why won't Rotax just go to the metal floats and be done with these problems?

    Hi Rich,

    Sorry I don't have an answer for that. It's above my pay grade. :)

    Maybe weight and or the design can't be done like the floats we have?

    My crystal ball sees an opportunity for a third party supplier to fill the void.

    Metal floats would be great, but the small user base probably does not justify the tooling.
    Plastic injection is much easier to implement but the quality of the foamed plastic is hard to control, as has been shown

    As a 912iS owner, I don't have a dog in the fight.
    The geek in me wonders if spraying a fuel proof coating on them would not seal them up and solve the problem.
