Slow Fuel Drip Drain Hole

[Jroseund]

Good Evening Everyone,

I wanted to pass this along to the braintrust here on the forum.

I have recently noticed after a flight I see a small trickle of fuel coming out of the drain hole that is on the underside of the right engine nacelle behind the landing gear. The fuel slowly moves forward to where it builds up by the oil drain tube underneath and then drops to the floor.

The Left engine is rock solid and I see nothing from that side, only from the right engine. When the Right engine is on ECU B I do notice a small amount of fuel coming out of the drain hole, but not enough to start dripping on the ground. When the ECU A is in command, after the flight I see a noticeable fuel spot on the ramp right under the oil drain tube; about the size of a small dinner plate. After wiping away the fuel on the bottom nacelle I can see it coming out of the drain hole. This happens for about 15-20 minutes then finally stops.

Could this potentially have something to do with the fuel pump that is dedicated to ECU A by chance? I have flown our 62 about 70 hours since August and is about 60 hours from the 200 hr check. She's at around 340 TT.

Thanks everyone for your input.

Jonathan, your serial number is not on this list but perhaps worth checking this all the same...

Thank you Vickers.

I’ll get that incorporated on the next event.

She was a hangar queen in her previous life. Since I’m flying her a lot more then the previous owner, I knew this sort of stuff was going to come up.
