Analysis

The commuter flight departed Kenai, destined for anchorage AK. The pilot stated that while on approach he could not obtain a positive gear down and locked indication on the nose gear. The pilot elected to return to Kenai airport due to weather at anchorage. Upon landing the nosewheel retracted. Examination of the nose gear revealed that a stainless steel flexible line enclosed in a protective rubber casing was chafed by a bolt in the nose gear scissors assembly. The stainless steel exterior mesh was rusted through and gave no support to the internal pressure line, thereby allowing the line to burst.
