John and Greg often make the point that flight safety involves both hangar and cockpit. This episode illustrates the point.

They walk through an accident involving a Cessna 177 Cardinal. The plane was in for annual maintenance. Although the mechanic had signed off in the logbook, the final run up was not completed before the pilot retrieved the plane.

The plane crashed shortly after takeoff. The investigation found no oil left in the engine. A loose oil cooler line suspected.

John and Greg highlight the need for mechanic and pilot to share information. Each individually has due diligence responsibilities as well as a shared responsibility to communicate.
