NTSB narrative
According to the flight instructor, during the initial climb, the student pilot noticed a problem with the elevator trim wheel. The flight instructor moved the trim wheel and noted no resistance. He then looked down at the wheel and observed the trim cable protruding from its side. The flight instructor assumed control of the airplane, advised the tower air traffic controller of the emergency, and landed the airplane without incident.
Examination of the elevator trim cable assembly revealed that the trim cable failed due to fatigue cracking of the individual wires. The wire breaks were so numerous and over such a sizable length that they should have been detectable by a visual inspection. However, a review of the aircraft logbooks revealed that maintenance personnel did not detect the fatigue cracking of the wires during the most recent 100-hour and annual inspections nor during compliance with an airworthiness directive (AD) that required, in part, that all control cables be inspected for broken wires strands and that any broken wire strands be replaced; the inspections and AD were accomplished less than 2 months before the incident.
Probable cause
The failure of the elevator trim cable due to fatigue cracking, which resulted from maintenance personnel’s repeated inadequate inspection of the cable.

- 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, coordinates, damage. 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.
