MDT FLIES WITHOUT PROPER LOGBOOK SIGNOFF OF AIRWORTHINESS DIRECTIVE.

Narrative

THE BAE ATP CURRENTLY HAS AN AIRWORTHINESS DIRECTIVE REQUIRING INSPECTION OF THE MAIN WHEEL BEARINGS AFTER EVERY SECOND LNDG. THIS IS CARRIED OUT TYPICALLY AFTER THE ACFT ARRIVES EACH TIME AT ORD ARPT. COMPANY MECHS PERFORM INSPECTION THEN SIGN OFF ACFT LOGBOOK NOTING AIRWORTHINESS DIRECTIVE COMPLIANCE. THIS IS TO BE VERIFIED BY CAPT BEFORE EACH DEP AT ORD. THIS WOULD BE FINE EXCEPT MANY ACFT COME AND GO; WITH MINIMAL NUMBER OF MECHS TO HANDLE AIRWORTHINESS DIRECTIVES AND OTHER MECHANICAL PROBS. SOMETIMES ACFT DO NOT GET IMMEDIATE AIRWORTHINESS DIRECTIVE ATTN UPON ARR. NEW CREW GOES TO ACFT AND MUST DETERMINE IF AIRWORTHINESS DIRECTIVE INSPECTION HAS BEEN DONE OR NOT. SOME SIGNOFFS WILL NOT HAVE A TIME OR FLT NUMBER NOTATED MAKING DETERMINATION DIFFICULT. ON THIS FLT I WAS UNSURE IF AIRWORTHINESS DIRECTIVE INSPECTION HAD BEEN DONE; BUT WITH QUICK CREW CHANGE AND SHORT TIME TO DEP; PLUS ANOTHER MECHANICAL PROB; FAILED TO VERIFY THAT INSPECTION HAD BEEN DONE. AFTER ARRIVING AT FIRST DEST REALIZED THAT I HAD FORGOTTEN; CHK LOGBOOK AGAIN AND FIND OUT THERE IS NO SIGNOFF FOR AIRWORTHINESS DIRECTIVE. THROUGH MAINT CTL CONTRACT LCL MECHS TO PERFORM AIRWORTHINESS DIRECTIVE INSPECTION AND AIRWORTHINESS DIRECTIVE SIGNOFF. COMPANY'S PROCS FOR ENSURING AIRWORTHINESS DIRECTIVE INSPECTIONS ARE VERY SLOPPY AND DO NOT TRACK ACFT SIGNOFFS FOR AIRWORTHINESS DIRECTIVE OR MAINTAIN ANY PAPERWORK FOR INSPECTION IF IT IS PERFORMED; BUT FAILED TO ENTER IT IN ACFT LOGBOOK. AIRWORTHINESS DIRECTIVE COMPLIANCE CANNOT BE COMPLETELY SHOULDERED BY CAPT WHO HAS MANY ITEMS IN PREFLT TO PERFORM AND VERIFY. MAINT PROCS OBVIOUSLY NEED MUCH IMPROVEMENT TO ENSURE AIRWORTHINESS DIRECTIVE INSPECTIONS ARE PERFORMED AS REQUIRED.
