Analysis

A piece of unidentified equipment reportedly was not properly secured during previous maintenance. The equipment reportedly was mounted immediately above the nose wheel extension/retraction mechanism and moved due to acft vibration preventing the nose gear from being extended. A landing was made with the main gear down and locked and the nose gear in the retracted position.
