The pilot/owner Prince Jean Ghica was attempting a non stop flight from Bicester, Oxfordshire, to Istanbul. While flying over the Region of Teteven, he was forced to attempt an emergency landing for unknown reason. While the aircraft was damaged beyond repair, the pilot was slightly injured.

The seaplane departed Istanbul at 1000LT on a mail flight to Athens with a crew of five on board. At 1230LT, the radio operator reported his position over Lesbos Island. About 30 minutes later, the crew encountered engine problems and attempted to ditch the aircraft in the Aegean Sea off the Ágios Efstrátios Island. SAR operations were initiated but no trace of the aircraft nor the 5 crew members was ever found, among them Captain Achille Rossi.
