General Maintenance Action
Aircraft
I was informed by company personnel that maintenance found during their post flight inspection that our aircraft was missing a ram air inlet door. Mid station inspection by my flight engineer was normal and the ram air inlet door was intact. Maintenance also completed an aircraft walk around at this stop. The exact time and where the door had come loose is unknown as all indications on the flight deck were normal.
A B727 Captain reported being informed after the fact that that an aircraft he flew apparently lost a ram air inlet door in flight.
