In our country, temperatures are between -20°C (-4°F) and +35°C (95°F)
with some snow in winter. I know that composite are now more reliable
but someone told me that Katanas had problems under high temperature
(wings distortions).


No temperature restiction on the DA40 Star. I have one, and live in
Texas, where summer surface temperatures routinely go over 100 degrees
F. There is a prohibition on painting certain areas of the aircraft
anything other than white, based on heat reflection.
