RJ85 Engines

[ACARS]

SLF on an RJ85 yesterday.

I know there is an exhaust port at the bottom of the engines. During taxi you can normally see smoke exhausting from the port (I assume this is normal).

Yesterday I saw sparks within the smoke plume and there was liquid coming from the wing. The liquid was dripping behind the engine exhaust.

It had not rained all day. Take off and flight was normal.

Any ideas of the where the liquid could have come from?

Don't know what the aircraft did before your flight and which weather it passed. Most probably moisture collected in-flight, frozen and melted away on the ground....so it was just water???

"The liquid was dripping behind the engine exhaust"

Then it is fuel,from pylon a bit FWD from the dripping point, from a evidence hole, that tell´s that the O-ring between the wing and pylon is leaking,P/n of O-ring PRo-180-256.
