200hp AEIO-360's have a max TBO of 1400hrs but please read note 6 of said SI !!
Link to CAP747 on the CAA website below.....
http://www.caa.co.uk/docs/33/CAP747.PDF you need G.R.24 in appendix 1
On Public Transport or Aerial Work , at the discretion of your maintenance provider/LAE , you may extend TBO 20% to 1680hrs.But please don't think this is your right to run the engine to this TBO , if you aerobat your aircraft regularly , your engine has a very hard life indeed . The constant alternating high/low power settings,accelerations/decelerations,momentary overspeeds,oil pressure fluctuations(even with an inverted oil system) and the nature of aerobatic flights(tend to be short trips , so hence many cylces) take a terrible toll on your donkey.In my experience most AEIO engines do not make TBO..........hope this helps,good luck !
