- Not recorded
- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Approach · IFR initial approach
- First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Loss of control in flight
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Destroyed
Cause areas
- Pilot in command › Aircraft control, not maintained
- Pilot in command › Design stress limits of aircraft, exceeded

NTSB narrative
THE PILOT WAS INBOUND TO THE CAPE GIRARDEAU ARPT FROM THE NORTHWEST ON A HEADING OF ABOUT 140 DEG, AND HAD RECEIVED CLEARANCE FOR THE ILS APPROACH TO RUNWAY 10 (INBOUND COURSE 104 DEGREES). RADAR DATA REVEALED THAT THE PILOT MAINTAINED A 140 DEG HEADING UNTIL RADAR CONTACT WAS LOST ABOUT 2 MILES SOUTH OF THE LOCALIZER COURSE. ALL RADIO TRANSMISSIONS WERE NORMAL. THE OUTBOARD WING SECTIONS SEPARATED FROM THE AIRFRAME PRIOR TO IMPACT. THE LEFT WINGTIP WAS LOCATED FARTHEST FROM THE MAIN WRECKAGE, AND WAS LOCATED ABOUT 600 FEET SOUTH OF THE MAIN IMPACT AREA.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN CONTROL OF THE AIRPLANE IN INSTRUMENT METEOROLOGICAL CONDITIONS AND THE PILOT EXCEEDING THE DESIGN STRESS LIMITS OF THE AIRPLANE DURING THE LOSS OF CONTROL. CONTRIBUTING FACTORS WERE THE EXISTING WEATHER CONDITIONS.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
