Narrative

ACR LGT ACFT ON TKOF FROM GRAND JUNCTION. ACFT EXPERIENCED COMPLETE LOSS OF 'A' SYS HYDS. CHKLIST PROCS WERE FOLLOWED AND THE ACFT WAS LANDED SAFELY BACK AT GRAND JUNCTION. I WAS THE CAPT OF THE ACFT. AFTER DEPLANING THE PAX; I PROCEEDED AS FOLLOWS: I PERSONALLY INSPECTED THE BROKEN HYD LINE IN THE L WHEEL WELL THAT CREATED THE HYD LEAK. I PERSONALLY SPOKE WITH THE CONTRACT MAINT INDIVIDUAL WHO CAME TO INSPECT THE ACFT AND EVALUATE THE PROBLEM. I PERSONALLY SPOKE WITH MY HOME STATION MAINT PERSONNEL TO DEVELOP A PLAN FOR FIXING THE ACFT. THIS INVOLVED FLYING IN COMPANY MAINT PERSONNEL WITH TOOLS AND PARTS TO FIX THE HYD LINE. I FILLED OUT THE COMPANY'S REQUIRED CAPT'S IRREGULARITY RPT RELATING WHAT HAPPENED AND THE ACTION TAKEN. I OBTAINED ROOMS AT THE HOTEL FOR MY CREW AND BRIEFED THEM AND THE GND AGENTS ON WHAT TO EXPECT AS TO THE ACFT'S STATUS FOR BEING FIXED. I FAILED TO IMMEDIATELY FILL OUT THE MOST OBVIOUS PAPER WORK OF ALL -- THE FLT LOG. AS LUCK WOULD HAVE IT; SOME FAA INSPECTORS WORKING AT THE ARPT STOPPED BY TO INVESTIGATE THE HYD LOSS INCIDENT. THEY DISCOVERED THE LOGBOOK HAD NOT BEEN FILLED OUT AND BROUGHT IT TO THE ATTN OF THE MAINT PERSONNEL WHO HAD BEGUN WORKING ON THE ACFT. THE MAINT PERSONNEL THEN FILLED OUT THE LOGBOOK WITH THE HYD LOSS PROBLEM AS I HAD RELATED IT TO THEM. UPON MY RETURN TO THE ACFT; I ADDED MY NAME TO THE WRITE- UP.
