## Discrepancy

(CAN) CONDITION PREVIOUSLY REPORTED BY ORGANIZATION 14 MARCH 2001.  VERTICAL STABILIZER AFT ADAPTER FITTING FOUND INSTALLED WITH THE LOWER LT MATING SURFACE MACHINED CYLINDRICALLY INSTEAD OF SPHERICAL CONCAVE. DATE OF MFG FOUND STAMPED ON THE PART AT REMOVAL: 18 APRIL 2000. THIS CONDITION CAUSES THE FUSELAGE AND STABILIZER SURFACES TO NOT MATE PROPERLY AT INSTALLATION.
