Diamond DA 40 Flight Manual page 20

General DA 40 AFM
CAUTION
The DA 40 is a single engine airplane. When the operating
limitations and maintenance requirements are complied with,
it has the high degree of reliability which is required by the
certification basis. Nevertheless, an engine failure is not
completely impossible. For this reason, flights during the
night, on top, under instrument meteorological conditions
(IMC), or above terrain which is unsuitable for a landing,
constitute a risk. It is therefore highly recommended to select
flight times and flight routes such that this risk is minimized.
