THE PILOT ROLLED THE ACFT WINGS LEVEL AND WAS FOUR TO SIX FEET AGL WHEN THE AIRCRAFT STALLED AND COLLIDED WITH THE RUNWAY. THE INVESTIGATION REVEALED ONE OF THE THREE WOODED PROPELLER BLADES HAD SEPARATED FROM THE HUB FOR UNDETERMINED REASONS.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19860823086719A](https://openairdocs.org/incident/19860823086719A), Aug 23, 1986: Brasov IS28B2, Porterville, CA, Substantial damage. The propeller cracked on takeoff forcing a return to the runway. The pilot stalled the aircraft near the runway.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
