@Mr Milk - what red dye in the hub do you mean?
There seemed to be a trail of similar fluid on the ground. The only fluids I can think of in a Cessna are Avgas, engine oil and brake fluid?
The fluid was red (wrong colour for oil), to heavy for fuel and appeared to be the right consistency for hydraulic fluid. The trail on the ground were blobs about the size of 50 cent coins spaced about 30cm apart for maybe 50 metres.
The fluid seems the same color as the stuff on the front of the cowl.
Not a big deal, just curious.
@gerry111 - I've got no idea who this squawk person is and don't care.
