I finally stopped trusting the old logbook entries after a close call in Phoenix.
We were doing a pre-flight on a Cessna 172 at the little field near Deer Valley, and the logbook said the last mag check was fine. My partner, a guy named Ray, decided to run it anyway and found a huge drop on the left side. The previous mechanic just wrote 'operational' without even pulling the plugs. Now I treat every log entry like a suggestion, not a fact. How do you guys handle it when the paperwork doesn't match the plane?
