Gentlemen- I am a licensed Commercial pilot with Instrument and multi engine ratings and over 2,500 TT on various aircraft such as the DC-3, King Air 90’s, Bonanzas, Piper Aztecs, Comanches, etc., but no turbine time In a residential move awhile back, I lost my log book that had all my hours I earned while flying in the AF. Can I still pursue the Regionals with these ratings if I cannot substantiate the hours? I am just north of 70 years old and have a Regional that wants to bring me on board to fly SIC on a King Air 90 with glass cockpit but we did not discuss logbook time. I figure I have a good ten years left in flying. What are your thoughts on this dilemma?
