Loose float guide pin
in 912 / 914 Technical Questions
6 years ago
A student and CFI experienced a strong fuel odor and brought the aircraft back for an immediate landing. A quick inspection of this Tecnam P2004 Bravo with a 912 ULS showed fuel pouring out of the bottom of the left carb float bowl. A detailed up close view found fuel pouring from a hole in the bottom of the float bowl. I removed the float bowl and found the inboard float guide pin had come out of its press fit hole. Bing drills these holes all the way through the bottom of the float bowl instead of having a blind hole. We put the pin back in place, checked the other pin and checked the other carb and sent them back out to finish their training flight.
Has anyone else had this happen? You can see how far the guide pins are pressed through from the bottom of the float bowl. Are they supposed to be flush with the bottom of the casting or is it acceptable for them to be slightly recessed?
