I did my primary training in several DA-20-A1s, and temperatures here
regularly reach the 90s in the summer. The underpowered A1 will barely
climb at that temperature (at gross), the C1s are no doubt better. The
restriction you are thinking of is that they cannot be flown WHILE the wing
spar temperature is above 131F (55C). There is no structural damage if the
plane is sitting on the ground at that temp. There is a little orange
sticker on the spar between the two seats which turns black if the plastic
is too hot to fly.

As our club want to buy a new DA-40 (Diamond Aircraft) and let it
outside I need some experienced advices.

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).

Has any private owner or a club any experience with a composite
aircraft not hangared during some years ?

Thanks in advance.
