Which company practices turn backs? Everyone stresses minimising thermal shocks and maximising engine life. Engine cuts at T/O power are an anathema to the mindset of every charter operator. And besides after 500+ hours on type, you get a feel for what an aircraft will or won’t do.
But, I guess these days with 500 hours in a 210, you’ll get Virgin or Qantas banging on your door with a start date. 🤣 So no one has any useful experience within a company. How times have changed!
In 8+ years of working in the piston engine world, I cannot recall any of my peers experiencing engine failures. No doubt they happened somewhere in the country but in the 70’s there was no social media for us to fixate on the minutiae.
