NTSB narrative
THE ACFT INVOLVED WAS EXPERIMENTALLY CONFIGURED WITH 4-BLADED PROPS AND WAS ON A TEST FLT TO DETERMINE HANDLING CHARACTERISTICS FOLLOWING A THROTTLE CHOP TO IDLE POWER AT 50 FT AGL. THIS MANEUVER HAD BEEN ACCOMPLISHED TWICE ON THE TEST FLT WITHOUT INCIDENT. ON THE THIRD LANDING, THE PLT LATER STATED, THAT HE RETARDED THE THROTTLES MORE BRISKLY THAN ON PREVIOUS APPROACHES. OBSERVERS ON THE PLANE AND ON THE GROUND THEN SAW A YAW AND A WING DROP. THE RIGHT GEAR STRUCK THE RWY FIRST, FOLLOWED BY THE LEFT AND NOSE GEARS. ALL THREE GEAR THEN SHEARED OFF. THE ACFT SLID TO A STOP OFF THE RWY 975 FT FROM INITIAL IMPACT. A POST-ACCIDENT TEARDOWN OF THE PROPS REVEALED NO PREEXISTING MISADJUSTMENTS OR ABNORMALITIES.

- 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.
