What was found
DURING A SCHEDULED INSPECTION, THE DOOR CHANNEL WAS FOUND TO BE CRACKED. THE CHANNEL IS THE MOUNTING LOCATION FOR THE CABIN DOOR HINGES AND CRACKS DUE TO IMPROPER ADJUSTMENTS OF THE DOOR, CREWS PULLING ON THE DOOR GETTING INTO AND OUT OF THE CABIN, AND INCORRECT INSTALLATION OF DOOR SEALS CAUSING STRESS ON THE CHANNEL.
