## Sequence of events

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

- In flight encounter with weather, takeoff - initial climb
  - weather condition - windshear (cause)
  - remedial action - attempted, pilot in command
  - compensation for wind conditions - inadequate, pilot in command (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - terrain condition - ground

## Analysis

THE PLT HAD JUST LOADED THE HOPPER WITH DYLOX CHEMICAL. AS THE ACFT BECAME AIRBORNE, THE PLT STATED, HE EXPERIENCED WIND SHEAR AND THE ACFT ROLLED TO THE RIGHT. THE PLT CORRECTED BY LEVELING THE WINGS AND IMMEDIATELY EXPERIENCED A SECOND MORE VIOLENT WIND SHEAR WHICH ROLLED THE ACFT TO THE RIGHT AGAIN. THE RIGHT WING CONTACTED THE GROUND AND THE ACFT CARTWHEELED. THE ACFT WAS TAKING OFF ON A HEADING OF 270 DEGREES.

## 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 19870518013969A](https://openairdocs.org/incident/19870518013969A), May 18, 1987: Scwzer G164B, Beaufort, NC, No damage. The aircraft encountered wind shear on takeoff and struck the ground. Pilot failed to check weather.

## Other investigations on N3628Z (1)

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.

- [NTSB GAA15CA266](https://openairdocs.org/ntsb/GAA15CA266), Sep 16, 2015: Schweizer G 164B (N3628Z), Paxton, NE, substantial damage. Probable cause: The pilot's failure to maintain adequate distance from a power line during low altitude flight operations, which resulted in an impact with the power line, and subsequent impact with the ground.
