## Analysis

FLT WAS BEING VECTORED FOR PRACTICE ILS APPROACH IN VFR CONDITIONS WHILE THE PLT-IN-COMMAND WAS RECEIVING A BIENNIAL FLT REVIEW. RADAR DATA SHOWED THE ACFT CONSTANTLY VEERING TO THE LEFT OFF ASSIGNED HEADING AND WITNESSES REPORTED ONLY HEARING ONE ENGINE RUNNING. THE ACFT'S SPEED SLOWED TO APPROXIMATELY 87 KNOTS AS SEEN ON RADAR AS THE ACFT WAS IN A LEFT BANK. THE ACFT'S RIGHT WING DROPPED AND THE ACFT ROLLED UPSIDE DOWN TO THE RIGHT AND ENTERED A SPIN CRASHING INTO THE YARD OF A HOUSE. WITNESSES HEARD THE ENGINES GO TO FULL POWER AS THE ACFT ENTERED A SPIN.

## 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 19880216002549A](https://openairdocs.org/incident/19880216002549A), Feb 16, 1988: Beech 58P, St Petersburg-C, FL, Destroyed, 2 fatal. Indicates stall at VMC caused a roll and spin from a medium bank. Check pilot may have retarded a engine for test.

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.
