Yep, annoys me because fixed props were always on Condition, would be checked on Airtests every 3 years to see if still performing ok..... We're they flying off left right and centre... no.
Seems like change for no benefit, well unless you are a overhaul shop.
Look at the seatbelt issue, replace every 10 years, now if you never carried a passenger you would change the pax one having never been used, the new AD that came out about certain makes being rewebbed goes on about not up to strength, not airworthy.. Not done to manual... Blah blah blah replace Blah blah blah, BUT the AD states If rewebbed before EASA start date you do not need to do it....
It's either safe or not that is a double standard AD
