Nine of the 10 bodies were picked up from the crash site on Thursday.
All the eight passengers and two crew of FlySax plane that crashed in the Aberdares died.
“There are no survivors,” Transport principal secretary Paul Maringa told a press briefing.
The bodies of nine victims of the Tuesday’s crash were brought down from the mountainous crash site Thursday evening.
The single turboprop Cessna Caravan plane, operated by local firm FlySax, lost contact with the control tower minutes before it was scheduled to land at Jomo Kenyatta International Airport while flying from Kitale.
The black box was recovered, officials said. It will provide clue on possible causes of the crash.
Investigations had started, a government statement said.
