The directive references a specific Cessna Service Letter (SL ME75-26) that contains the technical instructions.\n\n**Who it affects:**\n- **Model 310Q** aircraft with serial numbers 310Q0401 through 310Q1160\n- **Model 310R** aircraft with serial numbers 310R0001 through 310R0330\n\n**Key requirements:**\n- **Inspection and modification** of emergency exit windows per the referenced service letter\n- **Alternative materials allowed:** Spartan Golden Glaze Spot Putty (or equivalent) can be used instead of \"Bondtite\" as specified in the service letter\n- **Deadline:** Must be completed within **50 hours of flight time** after 18 November 1975\n\n**Why it matters:**\nAirworthiness Directives are legally binding safety mandates. Failure to comply means the aircraft cannot legally fly. This particular AD addresses potential safety issues with emergency exit windows — critical for passenger evacuation in an emergency.
