NTSB narrative
The Maule M-5-180C airplane touched down on the main landing gear, and then the tailwheel touched down shortly thereafter. The pilot then experienced a "very strong pull to the left," and attempted to correct with aileron and rudder. The airplane departed the runway to the left, struck the wing, and came to rest upright. Examination of the tailwheel revealed that the retention clip for the right compression spring was missing, and the spring had disconnected from the swing arm. The retention clip was not recovered.
Probable cause
The disconnected tailwheel compression spring, which resulted in a loss of directional control.

- 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. 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.
