Was this DA - 40 powered (using the term 'powered' loosely) by those Thierlert??? diesel jobs?? Im sure you could find an example of an inflight shutdown of one of these with less than 123hrs tt on it if you looked.. hence the lycoming conversion now available. And at 123hrs tt with probably only 2 inspections carried out on the aircraft ever (1 - 50hr and 1 - 100 hr) i would think the engine driven fuel pump would not have even been called up for an inspection yet?!! Hard to blame poor maintenance on something that ain't been fiddled with yet...
In saying all that im in no way familiar with the DA maintenance manual and required checks..
"because leaving this kind of plane in the sun(32 degrees 90% humidity) or on the beach of Pangandaran makes any flight dangerous..."
Same could be said for that plastic piaggio thing whatever it is.. i would imagine that will be reasonably maintenance intensive in the future living on the apron.
