Folks,
If you look at the latest edition of the C441 Maintenance Manual, Cessna have imposed a retirement life of 22500 hours on the pressure hull.
As they are the type certificate holder, Cessna (under our legislation) didn't leave CASA much option, except which legal mechanism to use to give effect to ensure compliance with the MM.
Very unfortunate, financially, loss of business as well as capital value, for those stuck with high hour Conquests, probably six or seven VH- over 22,500h.
Regards,
