## Analysis

THE PLT RPRTD THAT DRG AN APCH TO RWY 6 AT DUSK, A SUDDEN SINK RATE DEVELOPED. HE APPLIED POWER & BROUGHT THE ACFT TO A CLIMB ATTITUDE; HOWEVER, HE FELT A 'THUD BENEATH THE AIRCRAFT' & NOTED THAT THE RIGHT MAIN GEAR LIGHT NO LONGER INDICATED DOWN & LOCKED. SUSPECTING THE RIGHT MAIN GEAR HAD SEPARATED, HE MADE A GO-AROUND. DRG A SUBSEQUENT LANDING ON RWY 24, HE SHUT DOWN THE ENGS & HELD THE RIGHT WING UP AS LONG AS POSSIBLE BY USING THE AILERONS. AS THE ACFT SLOWED,THE RIGHT WING SETTLED & THE ACFT WENT OFF THE RIGHT SIDE OF THE RWY. GOUGES WERE FND SHORT OF RWY 6, WHERE THE RIGHT MAIN GEAR HAD HIT THE GROUND & SEPD FROM THE ACFT.
