This is episode 42, and we’re diving into a particular category of aviation accidents — those that happen right at the beginning of a pilot’s journey. We’re talking about ab initio training mishaps.
Ab initio, Latin for “from the beginning,” refers to a training path designed for aspiring pilots who start with zero flight time. Nothing. Not a minute logged, not a system diagram understood. These courses take students from ground zero to the right-hand seat of a commercial flight deck — through a tightly structured mix of theory, simulator time, and real-world flying.
They’re intense and sometimes quite fast. And they aim to do two things: produce skilled, airline-ready pilots and identify those who should probably find another career.
Many of these programmes are tied directly to airlines, which means you’re taught from the outset to fly their way — their SOPs, their ethos, their cockpit culture. That brings clear advantages. The pathway is laid out: from the classroom to the cockpit, without the detours of fragmented, school-hopping training. For many, there’s financial backing too — covering tuition, even living costs — opening doors for those who’d otherwise never afford to fly.
There’s also the camaraderie. Like a military intake, you form close bonds under pressure, guided by seasoned instructors and surrounded by peers. And at the end, a job may be waiting — conditional on success.
But it’s not all lift and no drag.
Freedom? Limited. You’re often bonded to the airline for years — and leaving early can come with steep penalties. Career flexibility? Not much. Your training is airline-specific, and if you decide to fly charter or head bush, you may be back at square one.
Contrary to the doomsaying of many veteran aviators, the accident rate during ab initio flight training in the United States has fallen by close to 50% — measured per flight hour - it shows between 2000 and 2019, the number of fatal training accidents almost halved. The Aircraft Owners and Pilots Association’s Air Safety Institute has the data to back it up.
In the early 2000s, the accident rate hovered around 0.49 per 100,000 flying hours. By 2009, that fell to 0.39. By 2019, the rate dipped to 0.26 per 100,000 hours — a substantial decline.
The top three causes of fatal training accidents haven’t changed much over time. They are, in order:
1. Loss of control in flight
2. Midair collisions
3. Controlled Flight Into Terrain — CFIT — the old nemesis flight into the granite cloud.

Episode 36 - The 1971 Aeroflot Antonov twin crashes and the ATR-72’s achilles boot
This is episode 36 and its icy cold out there - it’s time to check out the incidents involving icing - starting with a short list and general description of the causes, then focusing on the two Aeroflot Atonovs accidents in 1971 and a design fault in the ATR-72.
There’s an unfortunately long list of commercial airliners lost due to icing, more than 540 accidents and events caused by aircraft icing by the late 1980s in the United States alone and most of these were fatal.
Anti-icing and de-icing research can be traced back to the early 1930s and in 1948, two scientists, AG Preston and Calvin Blackman conducted the first successful iced flight experiment in which the drag coefficient increased by 81% when the wing was covered and the pilot reported the plane was almost beyond control. I’m not sure of what aircraft they used but the results were extraordinary.
Other research by NASA on the DHC-6 Twin Otter aircraft measured various conditions and ice shapes and their effect on aircraft thrust, landing flaps, and angle of attack.
It’s thought that the first recorded case of a commercial airplane accident caused by icing occurred on December 15, 1920 when a de Havilland DH.4 mail plane operated by the United States Post Office Department crashed near Belleville, Pennsylvania, in the USA due to ice accumulation on the wings and control surfaces.There was a happier end to another on 19th December 1946 where a Railway Air Service Douglas Dakota 3 stalled on take-off 1 km north-east of Northolt Airport in London.
This was the case of the scheduled service to Glasgow Airport from London. Four crew and one passenger were on board .. Yes, you heard correctly, one passenger.So to matters more terminal if you excuse the extremely cheesy aviation pun.
That be the highly unusual twin crashes of the Antonovs in 1971 both caused by ice accretion. ot Antonov An-12s crashed on approach to Surgut International Airport, just nine days apart. The crashes occurred under near-identical circumstances due to the aircraft type’s lack of preparedness for flying in severe icing conditions.
It’s the formation of an ice ridge by water droplets beyond the ice protection system and one side anti-icing system that is likely to cause rolling and overturn according to research documents.
A case in point of the ridge cause was an ATR-72 crash in 1994. At that time, the airplane was at a severe level of icing condition, and the co-effect of the electric heating de-icing system at the wing leading edge and the natural conditions formed an ice ridge on the second half of the wing, resulting in a negative pressure zone on the one side's aileron.
