## Discrepancy

ON ROLL OUT AFTER LANDING THE LH LANDING GEAR RETRACTED UNCOMMANDED CAUSING A PROPELLER STRIKE AND LH WING TIP TO TOUCH GROUND. UPON INVESTIGATION IT WAS DISCOVERED THAT THE LANDING GEAR SUPPORT BOX THAT BONDS TO THE SPAR HAD COME DETACHED FROM THE SPAR DUE TO A COMPOSITE GLUE FAILURE CREATING A CLEAN SEPARATION ALLOWING THE GEAR TO FOLD INWARD ALTHOUGH THE HYDRAULIC ACTUATOR HAD NOT COLLAPSED.
