What was found
(CAN) THE ACFT WAS ON A ROUTINE MEDEVAC FLIGHT WHEN THE FLIGHT CREW NOTICED THAT THEY COULD NOT PRESSURIZE THE CABIN TO MAX DIFFERENTIAL. UPON LANDING, THE SNAG WAS REPORTED TO MAINTENANCE WHICH RESULTED IN AN INSPECTION OF THE ACFT. A GROUND PRESSURIZATION CART WAS USED WHICH REVEALED A LARGE CRACK IN THE LT EMERGENCY EXIT DOOR AROUND THE LOWER FORWARD RADIUS. THE ADJACENT STRUCTURE OF THE FUSELAGE ALSO APPEARS TO BE CRACKED OR SCRATCHED. THERE ARE ALSO LARGE LEAKS AROUND A BELLY ANTENNA AND THROUGHOUT MANY OF THE RIVETS IN THE FUSELAGE. THE ACFT CURRENTLY HAS 15,868.9 A/F HOURS AND 14,286 CYCLES. THE ACFT HAS BEEN REMOVED FROM SERVICE UNTIL A FURTHER ASSESSMENT CAN BE PERFORMED.
