## 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 - base leg/base to final
  - airspeed - not maintained, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
- In flight collision with object, landing - flare/touchdown
  - object - tree(s) (contributing factor)

## Analysis

THE SCHWEIZER SGS-2-33A WAS IN THE TRAFFIC PATTERN WITH A STUDENT PILOT AND FLIGHT INSTRUCTOR. IN THE RIGHT TURN FROM BASE TO FINAL, THE NOSE DROPPED AND CONTROL WAS LOST. THE FLIGHT INSTRUCTOR TOOK CONTROL OF THE AIRCRAFT, AND REGAINED CONTROL, HOWEVER, INSUFFICIENT ALTITUDE REMAINED TO REACH THE RUNWAY. AN OFF-AIRPORT LANDING IN TREES WAS MADE. THE PILOT REPORTED THE WIND VELOCITY AT 5 KTS WITH GUSTS TO 10 KNOTS. THE CFI REPORTED THE WINDS AS 10 KNOTS.

## 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 19871024074859A](https://openairdocs.org/incident/19871024074859A), Oct 24, 1987: Scwzer SGS233A, Mansfield, MA, Substantial damage. Became too low in pattern. Settled in trees off airport. CFI blamed gust, causing glider to veer away from airport.

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.
