Actually, Perspective, the discussion about TBOs is directly on topic.
I will bet Brooklyn Bridge to a brick that none of the 10 deaths in the last 42 days was caused by an engine being past TBO.
Continuing on past an engines TBO on condition is testament to the fact that they 'may' run longer given a certain set of parameters met but that same 'acceptance' or belief isn't extended to commercial Ops, now I wonder why that is?
Wonder no more!
It’s because of the ‘mystique of aviation’ and the warm inner glow of the blissful ignorance arising from the belief that an engine before TBO is ‘safe’ and an engine past TBO is ‘not safe’.
The left engine on Chieftain VH-MZK was estimated to have had only 262 hours since its last overhaul and the right 1,395. Were those engines ‘safe’?
