The body of the other pilot was recovered after the plane crashed Wednesday evening about 3 miles (5 kilometres) from the runway in St. Maarten, said Wendell Thode, an official with the Dutch Caribbean Coast Guard, which was co-ordinating search efforts that included Dutch marines, volunteers and French authorities.
The cause of the crash was unknown. The government said local aviation authorities would conduct an investigation with assistance from experts from the U.S., where the plane was registered, and Britain, where it was manufactured.
The names of the pilots were withheld until their families could be notified.
St. Maarten is part of the Kingdom of the Netherlands and shares an island with French St. Martin.
The Skyway Enterprises twin-engine SH36 aircraft was en route to Puerto Rico at the time of the crash. Skyway Enterprises, based in Kissimmee, Florida, was operating under contract with FedEx.
