  • Re: Floats ... again ... ?

    My engine 912uls is 2011 era and I now have 7 years of flying and 900 hours with the original floats that still weigh properly. One float is getting close to the weight limit.

    I see an interesting detail on the section of the old and new floats shown on page 10 of the SB-912-074 Service Bulletin: look at the metal pin which protudes from the side of the float. Older floats have a retaining shoulder to positively anchor the pin into the plastic foam material. The new floats does not have this shoulder anymore. I bet we will have pins getting out of the floats one day... and another Service Bulletin on those bloody floats!

    Install the new floats as soon as you receive them. I received mine a week ago and put them on the shelf.  My late 2018 build 912UL has just over a year in service and just over 70 hours total time, has been fed only fresh, ethanol-free gas, so, I’ll install them later as the SB instructions allow, or so I thought.  This morning when I opened the hangar to preflight, I noticed a small puddle of gas by the front tire.  A carburetor was leaking fuel from the K&N air filter.  When I pulled the float bowl the floats were sitting at the bottom of the bowl.  They weighed over 8.5 grams. The ones on the other side were still floating, but they were overweight as well.  Could have been an memorable experience if those floats decided to wait to sink during the flight.
