Narrative:
The aircraft had just leveled off at FL190 when we experienced a complete failure of the right hydraulic system. Quantity and pressure both went to zero. Complied with abnormal procedures in the pom. Declared an emergency with ZTL. Vectored to an extended final runway 9L atl. Landed uneventfully runway 9L atl with emergency equipment standing by. Callback conversation with reporter revealed the following information: the reporter stated the aircraft was an MD88 and the cause of the right hydraulic system loss was a failed 'B' nut and line connection to the right hydraulic system return filter bowl. The reporter said the line and filter are located in the right main wheel well aft bulkhead.

Title: AN MD88 LEVELING OFF AT FL190 DECLARED AN EMER AND DIVERTED DUE TO COMPLETE LOSS OF R HYD SYS CAUSED BY A FAILED LINE.
Narrative: THE ACFT HAD JUST LEVELED OFF AT FL190 WHEN WE EXPERIENCED A COMPLETE FAILURE OF THE R HYD SYS. QUANTITY AND PRESSURE BOTH WENT TO ZERO. COMPLIED WITH ABNORMAL PROCS IN THE POM. DECLARED AN EMER WITH ZTL. VECTORED TO AN EXTENDED FINAL RWY 9L ATL. LANDED UNEVENTFULLY RWY 9L ATL WITH EMER EQUIP STANDING BY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE ACFT WAS AN MD88 AND THE CAUSE OF THE R HYD SYS LOSS WAS A FAILED 'B' NUT AND LINE CONNECTION TO THE R HYD SYS RETURN FILTER BOWL. THE RPTR SAID THE LINE AND FILTER ARE LOCATED IN THE R MAIN WHEEL WELL AFT BULKHEAD.
