Exactly my take!
The weird part of the 1200h TCI clutch is that the column denoting "hours done at installation" specifies 1300h,
I'd see that as
100h past end of service life. How can it be legal to install such item in the first place?
Furthermore the coumn titled "remaining time" reads -400h.
How can an a/c be airworthy when even the official log claims that an item is 400h past "TCI life"?
I'm talking about an F28, cared for by an EASA CAMO, mind you.
So I thought the reason must be TBO vs. TCI:
Is it possible that a freewheeling clutch has to be
inspected every 1200h
but - as long as it passes the inspection - in fact is
on condition?
Maybe sepcifying a TCI of 1200h only establishes a well defined frequency of inspections for OC items?

from
https://en.wikipedia.org/wiki/Time_between_overhaul
"For aircraft used non-commercially overhauls are not mandatory, but highly recommended."
Is that actually true? A helicopter with lapsed TBO is still airworthy as long as its not used commercially?
(I've learned and witnessed otherwise)
