This is a *very* annoying issue. There is a *set* of pistons of which SOME have been found to be manufactured with some measurements not to specification. Piston diameter itself and the diameter of connection point holes. Not all of a production run, apparently, or not enough of an issue with all t...

I replaced the pump after I bought the plane. I had this issue with my new pump. The pressure relief valve needs to be correctly adjusted. Also, if you leave the pump on after the motor has been turned off the pressure in the line gets quite high.

I don't understand why fuel needs to be transferred to the main tank. The normal swapping left to right should be sufficient no? From a systems perspective, providing a transfer pump seems overly complicated. You may be missing an important element of the DA40NG and DA50 fuel systems operation: The...

I just want to say thanks for all the thoughtful comments on this thread!

I don't want to cross-topic but a few comments here made me think there was some progress between Diamond and Garmin in adding ADS-B to DA40 G1000 WAAS aircraft (my adding: ideally so traffic shows up along with TCAS on the MFD). I have been away for awhile and looking for the best available soluti...

Most single engine aircraft require some fuel tank management. The DA40 and SRxx both require switching between R and L tanks at the appropriate times. My DA40NG requires the same fuel transfer from R to L as the DA50 and it's never been an issue. In the event of transfer pump failure, the engine b...

I was astonished by the price tag for the DA50. I cannot for the life of me understand what Diamond is thinking. After reading the AFM, most notably the performance tables, it is baffling. A few things stand out which collectively make me wonder what the conop is behind the DA50? Who are the custome...

I have the Composite 2-Blade. I really like it. The lowest idle isn't great vibration-wise but anything above 900 seems fine to me. I have not flown any other DA40's. Another advantage of both Hartzell propellers is that they can be run at 2700 continuously (Or 2550 which is the # that is best for t...

I have to say I have really enjoyed the DA40 so far. The plane is stable, well mannered and fun to fly. It is unfortunately not fast enough or big enough for what I want to do eventually. This of course leads to a number of lines of thought. I however cannot see stepping up into a newer Diamond give...

That is funny ... on Friday I sent a query to support regarding this topic but not having seen these recent posts. Their response: "Hello Logan, I'm sorry but we do not have any release dates to share for new software on the DA40 at this time. If you have any further technical questions, feel f...
