If the turn forces did not dislodge the prop, what did? After that great crew brought their plane to a stop, the maintenance records for #4 engine may have been first on their minds, after safely deplaning the passengers. When one considers the props pull the plane along, then what ever bearing that holds that (turbo) prop to its gear case comes into focus. ...

In a coordinated turn, this is purely a geometry question. Let's call the distance from centerline to engine $d$. The plane must bank to allow for centripetal acceleration $a=v^2/r$ with $v$ true airspeed and $r$ turn radius. This places the engines at a lateral distance of $$d^*=\frac{d}{\sqrt{1+\frac{a^2}{g^2}}}$$ from the centerline with $g$ acceleration ...

A large Bergen diesel will use 175 g/kWh at 85% of max load. At 600 kW per cylinder so a v16 is 10 MW or 13,000 shp. It will also weigh 150 tonnes, vs a TP400 gas turbine that weighs 2 tonnes and generates 11,000 shp at 210 g/kWh https://www.rolls-royce.com/~/media/Files/R/Rolls-Royce/documents/marine-product-finder/diesel-and-gas-engines-brochure-1216.pdf ...
