8. OVERHAULS
8.1. A major inspection at TBO is to be performed by the manufacturer or
approved service centers only. For this purpose the engine is to be sent
with its logbook to the manufacturer or the nearest approved service
center. The recommended time between overhaul (TBO) is at present
1000 hours of operation and this overhaul must be performed within 8
years after shipping. An increase of TBO due to field experience will be
published in the Service Bulletins of the manufacturer.
8.2. Major repairs and major modifications are also only to be performed
by the manufacturer or by approved service centers, which are
authorized by the manufacturer. In case of prop strikes or sudden
stoppage, the engine must be disassembled and the crankshaft must be
checked for cracks. This is considered a major repair and must be
performed by the manufacturer or an approved service center. If
stoppage of the engine is concealed when ordering a repair or major
overhaul, the responsibility for the damage and subsequent costs still
exists for the owner concealing the damage.
