Last summer (August 2022) I noted several aircraft wfu at this airport.
Besides Piper PA-31T Cheyenne II TT-DAO a B90 without engines/wings/tails was seen marked "F-PARC" with "Grenoble Alpes-Isere" titles, sporting brown engine cowlings and a light brown coloured belly.
This seems to be a non-existing serial. Does anyone know more about its true identity?
