"Unfortunately, from the reports we are getting there are no survivors. The families of the passengers and the crew have been notified and as a ministry, we truly regret this very sad outcome and send out our heartfelt condolences to the bereaved families," said Paul Maringa, principal secretary of the transport ministry.
A surveillance helicopter spotted the wreckage of the Cessna plane belonging to the FlySAX airline near the town of Njabini on the edge of the Aberdares mountain range early Thursday morning.
Search teams were dispatched to the site.
"It is with a heavy heart that I wish to inform you that we have received information there are no survivors in the recent incident that we had," FlySAX chairman Charles Wako told journalists at the Weston Hotel after briefing families who had gathered there at a crisis centre.
The plane, operated by East African Safari Air Express, took off from the western town of Kitale in the late afternoon Tuesday.
It disappeared off the radar screens at Nairobi international airport, its final destination, around 80 minutes later, the owners said in a statement.
Kenya has been experiencing heavy rains which along with foggy conditions hampered search efforts by the Civil Aviation Authority, Kenya Wildlife Service, air force and Red Cross.
President Uhuru Kenyatta said the families of the victims would "have every assistance my administration can offer, now and in the days to come. They can be sure that there will be a full review of our procedures, so that we can all understand how this tragedy happened."
According to the International Air Transport Association (IATA) in 2014, some 130,000 planes land and take off from Kenya each year, and the country has 35 operating airlines.
The IATA said Kenya's air transport infrastructure quality ranks 6th out of 37 countries surveyed in Africa.
In October 2017 five passengers were killed when a helicopter crashed into Lake Nakuru, while in 2012 a helicopter carring internal security minister George Saitot crashed, killing all six passengers on board.
Kenya's worst crash in recent years took place in 2007, when a Kenya Airways flight from Abidjan to Nairobi via Douala crashed into a swamp after take-off, killing all 114 passengers.
In 2000 another Kenya Airways flight from Abidjan to Nairobi crashed into the Atlantic Ocean minutes after take-off, killing 169 people while 10 survived.
