## Analysis

THE COMMERCIAL PILOT FLIGHT INSTRUCTOR (PIC) WAS CONDUCTING AN INSTRUCTIONAL FLIGHT WITH A RATED PILOT AT POMPANO BEACH AIRPARK. AFTER CONDUCTING A TOUCH-AND-GO LANDING THE PIC WAS INFORMED BY THE CONTROL TOWER THAT THE LEFT MAIN LANDING GEAR WAS IN THE TRAIL POSITION. THE PIC ACKNOWLEDGED THE RADIO CALL AND RETURNED TO THE COMPANY MAINTENANCE BASE LOCATED AT FORT LAUDERDALE EXECUTIVE AIRPORT. EN ROUTE TO THE DESTINATION AIRPORT EMERGENCY PROCEDURES WERE CONDUCTED WITH NEGATIVE RESULTS. UPON ARRIVAL THE PIC CONDUCTED A LOW PASS BY THE CONTROL TOWER AND VERIFIED THE UNSAFE GEAR CONDITION WITH A VISUAL EXAMINATION OF THE AIRPLANE BY THE CONTROL TOWER AND AN UNSAFE LANDING GEAR LIGHT IN THE COCKPIT. THE PIC REENTERED THE TRAFFIC PATTERN AND LANDED. ON LANDING ROLLOUT THE LEFT MAIN LANDING GEAR COLLAPSED AND THE AIRPLANE SUSTAINED SUBSTANTIAL DAMAGE. NEITHER CREWMEMBER WERE INJURED. EXAMINATION OF THE LANDING GEAR BY MAINTENANCE PERSONNEL REVEALED THE MAIN GEAR PIVOT ASSEMBLY HAD FAILED.
