## Discrepancy

WHILE PERFORMING A 100 HOUR INSPECTION FOUND THE LOWER COCKPIT CHANNEL AT FUSELAGE STATION 128.737. CRACKED AND BUCKLED. THIS CHANNEL IS THE CARRY THROUGH STRUCTURE FOR THE AFT WING ATTACH FITTINGS. THERE IS NO OTHER DAMAGE TO WINGS OR FUSELAGE STRUCTURE. THE DATA ACQUISITION UNIT FOR THE PFD/MFD IS MOUNTED AT THIS LOCATION AND COULD MAKE INSPECTION OF THE AREA DIFFICULT. THE DATA ACQUISITION UNIT WAS REMOVED FOR TROUBLESHOOTING.
