## Discrepancy

(CAN)   ON T/O,  A CLUNK HEARD NEAR END OF MLG TRAVEL DURING RETRACTION.  NO DIFFERECE IN FLT CONTROL.   PILOTS INFORMED RT MLG HANGING.  MLG SELECTED DOWN STEEP BANKS & YAWS PERFORMED TO GET RT MLG LOCKED.  NO DOWN & LOCKED IND EVIDENT, A/C LANDED UNEVENTFULLY.  RT MLG NOT LOCKED, SIDE BRACE LOCK NOT OVER-CENTER AND DOWNLOCK SPRING BROKEN.  JACKED A/C, RT TORQUE TUBE ASSY BROKEN AT OTBD PUSH-PULL TUBE ATTACH POINT.  INVEST REVEALED A CRACK AT ATTACH POINT.  THERE IS NO SPECIAL INSPECTION ON THIS PART OF MLG, DIFFICULT TO DETECT A CRACK WITHOUT REMOVING TORQUE TUBE FROM A/C.  TORQUE TUBE AND RETRACTION SYSTEM TEARDOWN AND INSPECT REQUIRE INITIAL INSPECTIONS AT 10000 HOURS. A/C HAS ONLY 7621.4 HOURS SINCE NEW.
