Are you leasing back to a school? If you are, ask them to fax you a copy of the last page of tech log once a week? That way you can check the hours and schedule...You will know how many hours you have left!
If not, you surely keep your tech log at home and therefore have all the hours / dates etc for maintenance???? Don't keep in the heli! (my advice)
Schools will always try and make money on the "great flying weather days" and guess what - thats the day YOU want to take her up!!!
I had mine on a lease back for approx 3 months then pulled out. No point in attempting to have the benefits of ownership if you can't fly eh??
