Narrative

AIRLINES FLT; AN MD88; DEPARTED WWW FOR YYY AT AB17 LCL TIME; MAR/MON/97. AT AB23 THE DISPATCHER AND MAINT COORDINATOR WERE CONTACTED BY THE CAPT VIA COMPANY RADIO. HE ADVISED THE COMPANY THAT HE HAD A 'NOSEGEAR UNSAFE LIGHT.' THE MAINT COORDINATOR AND DISPATCHER REVIEWED POM PROCS WHICH HAD BEEN FOLLOWED BY THE CREW. AFTER REVIEW OF PROCS; FUEL FLOW; FUEL ONBOARD; ENRTE WX; ENRTE ALTERNATES IF NEEDED AND OTHER FACTORS; THE CAPT; MAINT AND DISPATCHER AGREED THE FLT COULD SAFELY CONTINUE TO YYY WITH THE GEAR EXTENDED. AIRSPD; ALT AND FUEL WERE MONITORED THROUGHOUT THE FLT. ENRTE ALTERNATES WERE RELAYED TO THE CAPT BY DISPATCH AS THE CAPT RELAYED FUEL FLOW AND ESTIMATED ARR FUEL TO DISPATCH. UPON ARR INTO YYY AIRSPACE; THE CAPT DECLARED AN EMER AS A PRECAUTION FOR THE UNSAFE GEAR INDICATION. HE THEN REQUESTED A 'FLY- BY' SO A VISUAL CHK OF THE LNDG GEAR COULD BE ACCOMPLISHED. AT AC47 LCL TIME THE CAPT MADE A NORMAL LNDG AT YYY WHERE HE STOPPED THE ACFT ON RWY 9L. HE WAS MET BY MAINT AND OTHER GND PERSONNEL FOR THE POLICY REQUIRED TOW TO THE GATE. WHILE THIS OP WAS CONDUCTED VERY CAREFULLY WITH THE ASSISTANCE OF MGMNT AND SUPERVISION ON SEVERAL LEVELS; THERE WAS NOT A CLRLY DEFINED PROC FOR THE CAPT; DISPATCHER AND MAINT COORDINATOR TO FOLLOW. THE POM STOPPED ONCE THE GEAR PROC WAS COMPLETED. CALCULATIONS WERE BASED ON THE ACFT FUEL FLOW AND ESTIMATED ARR FUEL. OUR DATABASE COULD NOT PRODUCE NUMBERS FOR DISPATCH TO GIVE THE CAPT. SPD AND ALTS WERE LEFT TO THE CAPT'S EXPERIENCE. HOPEFULLY; AS A RESULT; A POLICY WILL BE ESTABLISHED; PRINTED AND CALCULATIONS MADE AVAILABLE TO THOSE WHO MIGHT REQUIRE THEM.
