Factual narrative
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. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
