It doesn't mention if anyone on the ground was killed or injured

Very sad. My heart and prayers goes to the bereaving family and those recuperating.

from Kenya Daily Nation

" The pilot of a cargo plane that crashed in Nairobi on Wednesday, killing him and three others, made a distress call moments before it plunged into a building.

Preliminary investigations showed that Mr Harrison Okang’a called the control tower seeking clearance to “transmit,” but did not utter any other word after he was given the go-ahead.

Instead, the plane changed course and investigators believe the pilot was attempting to make an emergency landing on a straight stretch on the Eastern bypass before it hit electricity lines, then the building before bursting into flames.

The Fokker 50, registration 5Y-CET, crashed at Utawala near the General Service Unit Training School at 4.17am, just two minutes after taking off from the Jomo Kenyatta International Airport.

It split into two on impact, with the flames leaving most of it completely destroyed.

Co-pilot Sayid Abdi, flight engineer Kevin Kamau and loader Geoffrey Masika perished.

Mr Okang’a, a father of five, is a veteran flier who retired from the Kenya Air Force in 1994 as a captain. He joined the Kenya Wildlife Service before he started flying for commercial airlines ferrying both passengers and goods across the region.

He first worked for Eagle Aviation, then Bluebird Airlines before joining Skyworld. He was experienced on the Nairobi-Mogadishu route as he had flown on it for many years."

Likely cause?
 

Left Engine failed?

Overloading?

Co-pilot flying?..inexperience?

Why "permission to TRANSMIT"? Transmit what?MayDay?

Forced landing scenario could be loss of control...similar to a not so distant Fly540 Fokker 27 crash on departing Wilson? Props didn't feather?

Any clues?Anyone?

Departure was 4am..and cool..so Weight might have been more a consideration than Density alttude?

F50 crash
 

A number of posts have been removed which suggested that the plane was (over)loaded with a mild legal stimulant grown in Kenya destined for the Somalia market---its a stimulant that is now banned in the UK

From the information I got from someone who was present during the loading, the aircraft was overloaded.

Apparently the aircraft usually carrier 4.5 pallets but on this occasion, the loading master, who sadly also perished in the crash, insisted on 6 pallets. I'm told all the records are available.

The hypothesis is that on take off, the cargo moved to the rear of the aircraft setting off a chain of events that precipitated the crash.

Cost of lives which could have been avoided. Human factors are the biggest killer in GA. Sad.

These planes are old and batered.Max TOW by the book with performance degradation is overweight already!

No rudder lock
 

I was working at the Jetlink hangar where 5Y-CET was parked and being washed for a couple of days before it took that last flight. I don't suppose it contributed to the crash but we did notice that the rudder wasn't locked was banging from side to side in the wind.

Well said and crew probably not sim proficient

"Fokker 50 crash crew ignored multiple alerts during take-off rollFokker 50 crash crew ignored multiple alerts during take-off roll.

By David Kaminski-Morrow21 February 2020

Kenyan investigators have disclosed that the crew of a Fokker 50 continued a take-off roll, despite multiple alerts apparently warning of a serious engine problem, before the aircraft crashed some 50s after becoming airborne.

The inquiry into the accident, involving a Skyward International Aviation turboprop departing Nairobi’s main international airport, found that 27 high-level ‘triple-chime’ alerts had sounded as the aircraft rolled along runway 06.

Aural alerts had commenced as early as 8s after the take-off was initiated but, while the aircraft was well below the V1 decision speed, the crew did not act to abort the take-off roll.

Flight-data recorder information indicates the left-hand Pratt & Whitney Canada PW125 engine was exhibiting problems, with increasing torque but declining propeller speed compared with the right-hand engine.

“On [its] ground roll for take-off, the aircraft seemed to take [more] runway than anticipated before attaining the take-off speed,” the Kenyan air accident investigation department states, indicating that the roll lasted over 90s.

The aircraft lifted off from the high-elevation airport at about 100kt but “barely climbing”, the inquiry says, reaching no more than 50ft above ground after about 20s while continually deviating to the left of the extended centreline.

It subsequently collided with a building 2,100m north-north-east of the runway end. None of the four occupants – two pilots, an engineer and a loadmaster – survived."
