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.
Analysis
The acft was landed gear up after attempts to lower the gear were unsuccessful. The system malfunctioned because the nose gear jammed the main gear during retraction. The jamming occurred because the nose strut did not extend due to lackof air pressure. The air charge added after the accident was holding 3 weeks later.
