Vitaliy , If it's the sort of program I 'm thinking it is, they are probably looking for cases just like this to discuss. It covers a wide area of topics at a variety of levels.:- Rental company attitudes Breakdown insurance Failure analysis. What happens when an engine ingests water - why it's a bad thing. Metal fatigue issues. Maintenance issues for IC engines - why regular oil changes and service is required. How to minimise the chance of getting into a situation like this - what questions to ask, what action to take. How to document events and get help when this situation arises.
