Hello. 

Can you get infos for the 912  SN 4400206

4400206 was produced 30-Jun-1995

Engine Type: ROTAX 912 UL

Model Number: 309120010

( no additional information is found in the factory database - this engine predates the electronic database by several years!!) 

Do you know about TBO on this version?

That engine is now less than 90 days from its calendar TBO date.

TBO 'hours' for that engine maxed out at 1200 hrs (1500 if specific maintenance procedures were carried out to extend the TBO - see your engine log book)

see https://legacy.rotaxowner.com/si_tb_info/serviceb/sb-914-039ul.pdf   and https://legacy.rotaxowner.com/si_tb_info/serviceb/sb-912-041-ul.pdf    for details of the TBO extension
