NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.
Anchorage, AK
JUST PRIOR TO THE MISHAP, MAINTENANCE ON THE AIRCRAFT HAD BEEN PERFORMED. THIS INCLUDED WORK ON THE CABIN HEATER IN THE NOSE WHEEL WELL AREA. AFTER TAKEOFF TO FERRY THE PLANE TO A NEARBY AIRPORT, THE NOSE WHEEL BECAME JAMMED AS THE GEAR WAS RETRACTED. THE MAIN GEAR COULD BE CYCLED BUT THE NOSE GEAR WOULD NOT EXTEND. WHILE LANDING WITH THE MAIN GEAR EXTENDED, THE NOSE SECTION AND PROPELLER TIPS WERE DAMAGED AS THE NOSE WAS LOWERED TO THE RUNWAY. AN EXAMINATION REVEALED THAT THE LEFT NOSE GEAR DOOR WAS PARTIALLY CLOSED AS THE NOSE GEAR RETRACTED. THE NOSE GEAR AND STRUT HAD CRUSHED THE DOOR INWARD AND UPWARD. THE CENTERING CAM/WHEEL STRAIGHTENER, THE UPPER NOSE WHEEL STEERING MECHANISM, AND THE GEAR RETRACT ARM MECHANISMS ON THE NOSE GEAR DOORS WERE WORN. ALSO, A LACK OF LUBRICATION WAS NOTED IN THE NOSE GEAR ASSEMBLY. THE AIRCRAFT HAD BEEN FLOWN APPROXIMATELY 15 HOURS SINCE THE LAST ANNUAL INSPECTION.
