Nigeria Vice President 139 crash
He has been in two helicopter crashes in 7 months - this part is probably worthy of an analysis!

Eniola Akinkuotu, Abuja
The helicopter conveying Vice-President Yemi Osinbajo crash-landed in the Kabba area of Kogi State on Saturday.
The Vice President’s media aide, Laolu Akande, however, said no one was hurt
A tweet by Akande read: “VP Osinbajo’s chopper crash lands in Kabba, but he and the entire crew safe. He is continuing with his engagements and plans for the day in Kogi State.”
The incident is the second air mishap that Osinbajo would escape in seven months.
On June 7, 2018, a chopper that was to convey Osinbajo from the Nigeria Customs Command and Staff College, Gwagwalada in Abuja, was forced to land, few seconds after takeoff.
Osinbajo was in the school for the graduation ceremony of Senior Division Course 1 /2018 participants. The chopper had earlier taken the Vice-President to the college for the ceremony.
However, while taking off, it could not ascend beyond the tree level, before it emitted thick smoke and landed on the same spots few seconds after takeoff.
Osinbajo later left the college by road.

However, streaks (e.g., of good or bad luck) are part of randomness. And without streaks a distribution is not random. As a matter of fact, when forensic auditors look a presumably random data, the absence of streaks make them suspect it could be cooked.

Helicopter crash: AIB concludes investigation - The Nation Nigeria

The completion of the investigation came on the heels of gathering of evidence – inspection of the chopper wreckage at the crash site; interview of airline crew- pilots, engineers and other technical personnel, eyewitnesses account, laboratory testing of broken rotor and other parts of chopper.
A source closed to the AIB said the preliminary report of the accident will be released in two days, but he could not give probable cause(s) of the crash.
Another source close to Caverton Helicopters, mangers of the crshed chopper, said its insurers have arrived in the country to participate in the probe.
The source hinted that the insurers, sought permission from the AIB, for access to the crash site to carry out valuation of the wreckage and other relevant activity critical to the accident probe.
Besides the insurers, it was not clear as at yesterday if the helicopter manufacturer – Agusta will participate in the inquiry.
According to the International Civil Aviation Organisation (ICAO)-prescribed aviation regulations, the aircraft manufacturers ought to participate in the investigation.
The involvement will enable the manufacturer learn useful lessons in preventing a reoccurrence; if there are issues with the equipment design or other technical hitches.
AIB’s spokesman Tunji Oketumbi said the bureau has concluded preliminary investigation on the crash, which he described as “high profile”, because of the status of the occupant in the ill-fated chopper.
He said an accident could be so described, if the aircraft was carrying many influential people; or there are many multi-nationals.
He said that will not in any way put any pressure on the AIB, which has so far utilised its internal capacity to discharge the onerous task.
Oketumbi said: “So far, the AIB has done what is statutorily required of it. We did not require any foreign assistance. We have carried out the relevant findings at the crash site and interviewed the crew and other people relevant to the operation. So, far, the helicopter wreckage has not been removed.”
He, however, took exception to the remarks attributed to Caverton Helicopters which suggested the probable cause(s) of the crash.
According to him, besides giving flight information – type of aircraft; registration number; number of occupant in the aircraft and circumstances of the accident, the airline should refrain from speculating the cause of the crash.
Doing such, Oketumbi said, will amount to pre-empting the investigation.
Recall that AgustaWestland AW139 is a 15-seat medium-sized twin-engined helicopter developed and produced principally by AgustaWestland.

The crash comic out of Nigeria I'm more interested in is the Bristow S76C++ that splashed down in the Atlantic, where all souls on board were miraculously saved by the remarkable show of courageous airmanship by the hero Captain. When are we likely to see the final report on that one?

The 76 crash I an familiar with was in the Lagos Harbor....and had fatalities.
The 332 had no fatalities but a very enjoyable video of folks bobbing around in Rafts in Monsoon rain....and the Coey muttering about how he could not keep it ouf of the water.

The problem is rather neatly summed up by this rather technical explanation of the previous 139 accident in Kenya
(that makes 50% of their fleet destroyed?)
"
To avoid the bird, the pilot tried to manually make the chopper rise using the lever known as the collective. However, this was impossible in autopilot mode where the aircraft cannot move up and down. It reportedly turned sideways and stalled.
A vortex was created, sucking the chopper in and down."Hovering out of ground effect, or HOGE, is an aviation term describing when a chopper appears stationary in the air. It generally requires more power than if it is on the ground. It is the act of the pilot pulling the collective that led the helicopter to lose power, making it fall to the ground," the source said."In technical terms, the rotors should spin at 110 percent its normal rotations per minute. If it drops to 98 percent,alarms will go off, saying 'rotor low, rotor low'. When this helicopter crashed, it was down to 96 percent RPMs. You could clearly hear the warnings in the voice recorder and the panicked engineer directing Oduk on what to do," the source said."

Jeez, you just can't make that stuff up.

As usual, people like to jump on reports in the tabloid press, which is exactly what this is - a Kenyan newspaper report from 2016. The popular press is the same the world over, sensationalist and with only elements of the truth. As far as I know no official report has been published yet (and there’s quite a possibility it may not be released to the public).
