BERLIN (AP) — The founder and CEO of the RSG Group of gym outlets, Rainer Schaller, has been confirmed dead after the crash of a small plane off Costa Rica late last month, the company said Friday.

The plane, a nine-seat Italian-made Piaggio P180 Avanti, disappared from radar just off the Central American country's Caribbean coast on Oct. 21. RSG Group, whose outlets include Gold’s Gym and McFit, confirmed shortly afterward that Schaller, family and friends had been on board.

The aircraft disappeared from radar as it was heading to Limon, a resort town on the coast. Costa Rica's security ministry said the flight had set out from Mexico.

All five passengers were German citizens. The plane’s pilot was Swiss.
