"My associate has just had to take a PA28-180 off-line at his flying school
and sell shares in it as the engine, with 1250 hours on it has passed 12 years old! It's no more or less safe because of that!"
In Lycomings opinon it is less safe! that is why they reccomend you overhaul it at 12 years or 2000 hours.
This is nothing new!
You can get a 20% extension to both the engine hours and callinder life, its all in Generic Recquirment 24 which used to be Airworthiness notice 35?
Lycoming also allow you to do more hours than the standard TBO if you are running the engine extensivley I think the figure is around 40 hours a month (its a while since I read the SB on it).
