Dear All,
Following the recent discussion about engine reliability (really
intermittent fuel starvation) I had the same very worrying problem 2 years
ago and eventually solved it.
We got very frustrated, took the fuel lines out and replaced them, did
the extra filter mod and even paid professional aero engine specialists to do
fuel flow checks - all was costly and unhelpful.
The real source of the problem became apparent when we inspected the fuel
tank's coarse indwelling filters - they were filled with electrostatically
charged swarf which must have been in the tank for months following the
installation of a digital fuel gauge. You need to really look hard for this
stuff as it will cling to the least expected areas of the tank and float into
the coarse filters upstream from the standard filters when you are in the
worst possible situation. Your case sounds so similar to ours that I am
convinced that dirt in the tank is the problem. Even if you have already
looked inside the tank - look again really carefully - we had to before we
figured things out.
Good luck with your fix,
James McDiarmid,
