## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, approach - vfr pattern - final approach
  - visual separation - inadequate, pilot in command (contributing factor)
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - improper, pilot in command (contributing factor)
  - go-around - initiated, pilot in command
  - airspeed(vso) - not maintained, pilot in command (cause)
  - stall/spin - inadvertent, pilot in command
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

PLT ENTERED THE LANDING PATTERN BEHIND A SLOWER ACFT (STEARMAN) AND REDUCED SPEED TO MAINTAIN A PROPER INTERVAL. THE NOMINAL APPROACH SPEED DIFFERENTIAL BETWEEN THE TWO ACFT MAKES IS 26 MPH. A RIGHT HAND TRAFFIC PATTERN WAS IN USE AND A RIGHT CROSSWIND PREVAILED, EFFECTIVELY REDUCING THE DESIRED INTERVAL ON BASE LEG (TAIL WIND). ON LNDG ROLL, THE STEARMAN PLT BROADCAST HE WOULD NOT BE ABLE TO MAKE THE FIRST TURNOFF. THE MISHAP ACFT WAS ON SHORT FINAL AT THIS TIME AND THE PLT BROADCAST HIS INTENTION TO EXECUTE A GO-AROUND. THE ACFT DRIFTED LEFT, OSCILLATED AROUND THE LONGITUDINAL AXIS AND ROLLED INTO A LEFT SPIN, IMPACTING THE GROUND 70 DEGREES NOSE DOWN, INVERTED. INVESTIGATION REVEALED NO MECHANICAL FAILURE OR MALFUNCTION.

## 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 19840428014589A](https://openairdocs.org/incident/19840428014589A), Apr 28, 1984: Cessna 310Q, Mckinney, TX, Destroyed, 2 fatal. Go around attempt, low airspeed and altitude, spun in. Throttles found in mid range setting, gear and flaps down.

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.
