Speaking about ACTs...
Got contacted recently by a colleague for a finding of a yellowish, glue type substance in the drain system of the space between the bladder and the "box", in the angled tube that is just underneath the ACT of an A320.
Heard a voice that said it may be a small leak from the bladder, and that fuel dissolves Dinitrol in the box, and this mixture then eventually clogs up the drain line (talking about small leaks!).
I have checked the A340 ACT CMM, and there is no reference to Dinitrol.
Any thoughts? Any experience?
