Sala’s body was recovered from the rubble on February 6, 2019, after a private search for the missing footballer and the pilot was commissioned by his family.
Ibbotson’s body has yet to be found and the plane has not been recovered either.
Henderson was convicted by a 10-2 majority verdict in October.
The court heard that Henderson did not have a Foreign Carrier Permit (FCP), which he was required to have for the US aircraft, and did not have the required Air Operator Certificate, according to PA Media.
He had already admitted that he “attempted to de-register a passenger without a valid permit or authorization,” reported PA Media.
In a statement provided to CNN, Cardiff City said: “Cardiff City Football Club welcomes the conviction and sentencing of David Henderson and supports the Emiliano family in their continued search for the truth.
“Clearly, several questions remain unanswered regarding the cause of the accident and the role that others played in organizing the flight.”
CNN reached out to Daniel Machover, who represents the Sala family, for comment.
