Like Frank, I add a column to my pilot logbook for time in my own plane. I don't log flights separately in the aircraft logbook, so I used the pilot logs to add it up when I needed to make a maintenance entry (until I bought the Starduster, the first plane I've had in years with an hour recording tach). I get pilot time from the clock on the panel or GPS log.
The greatest stresses (normally encountered) on an air frame result from taxiing for take off and the take off roll.
