What was found
DURING INSPECTION FRAME (PN 262106510) WAS FOUND CRACKED AT THE CONTROL COLUMN BEARING MOUNT ON THE RT SIDE. THIS WAS THE IMPROVED BEARING MOUNT SETUP AS CALLED OUT BY AD AND SB TO PREVENT CRACKING. THE CRACKS ARE OCCURRING RIGHT AT THE TOP OF THE IMPROVED (PN 2621352-001/005) DOUBLER ASSY. BELOW THE RADIUS ON THE 26-21065-10 FRAME. THIS APPEARS NOT TO BE A FLUKE. THIS IS THE SECOND AIRCRAFT FOUND WITH THIS PROBLEM. MFG HAD ANOTHER SB CONCERNING THIS AREA THAT CHANGES THE MOUNTING AGAIN AND MAKING THE DOUBLER LONGER TO SPREAD OUT THE LOAD BETTER TO THE FRAME.
