Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Landing gear,normal retraction/extension assembly - disabledCause
Hydraulic system,fitting - fatigueCause
Hydraulic system - leakCause
Acft/equip,inadequate designManufacturerFactor
In flight collision with terrain/waterLanding - flare/touchdown

Analysis

The commuter air carrier crew received an unsafe nose gear indication on final approach. The approach was abandoned and all efforts to use the emergency extension procedures were to no avail. The crew secured both engines on final and landed nose gear up. Examination revealed that all hydraulic presure was lost due to a right main landing gear actuator end cap failing in fatigue.
