Re: Unbalanced fuel usage

Thanks for the replies. After a flight today the problem has gone away. We are convinced that somehow the fuel selector valves were not fully closing after the cross-feed check and lots of ground checks and movement of the levers has somehow rectified the issue.

Re: Unbalanced fuel usage

Thanks for the comments. We have now heard that another DA42 has had a similar problem so we are investigating how that one was fixed. I will report back any findings.

Re: Unbalanced fuel usage

The aircraft is infrequently used and kept in a hangar so we know it isn't leaking sat on the ground. 9 gallons is a lot to lose though.By staining I thought if it was leaking then dirt will stick to it wherever it is parked as opposed to fuel dye staining. Jet A1 (diesel) takes a while to evaporate.

Re: Unbalanced fuel usage

The total fuel used is as expected for a flight of this length. So no leakage otherwise the a/c is using less than the 11usg total/hour (verified by fuel flow meters and previous historic data). Also no evidence of fuel leak at all ie staining of aircraft. This is not one isolated flight but a resul...

Unbalanced fuel usage

New to the forum but we have an issue with a DA42 Tdi and balanced fuel usage. The aircraft is a 2006 aircraft with low hours, approx 450, with no issues to date at all. However for some reason we have found that we are putting more fuel in one wing tank (incl aux) than the other by some margin ie 1...
