## Analysis

WHILE EN ROUTE AT 12,500 FT, THE PLT NOTED A SLIGHT SHUDDER & HEARD A 'WIND NOISE' THEN THE GEAR UNSAFE LIGHT ILLUMINATED. THE PLT SLOWED THE ACFT TO 135 KTS & TRIED RECYCLING THE GEAR, BUT THE GEAR ONLY DROPPED TO THE POINT WHERE IT WOULD TWIST. ALL ATTEMPTS TO LOWER THE GEAR WERE TO NO AVAIL. THE PLT THEN FLEW TO KINGSTOWN & LANDED WITH THE GEAR UP. AN EXAM REVEALED THAT A HYDRAULIC LINE, PN 6790244-227, HAD FAILED.
