## Probable cause

IN FLIGHT ENCOUNTER WITH WEATHER, HIGH DENSITY ALTITUDE. CONTRIBUTING TO THE ACCIDENT WAS AIRCRAFT GROSS WEIGHT WHICH WAS EXCEEDED.

## Sequence of events

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

- In flight collision with object, descent
  - object - tree(s)
  - weather condition - high density altitude (contributing factor)
  - aircraft weight and balance - exceeded, pilot in command (cause)
  - clearance - not maintained, pilot in command (cause)

## Analysis

THE ACFT WAS 676 POUNDS OVER GROSS AT TAKEOFF.  DURING THE FIRST SPRAY PASS ON AN 88-DEGREE DAY, THE PLT STATED THAT THE ACFT BEGAN TO SETTLE. HE APPLIED POWER BUT THE ENG DID NOT RESPOND. THE ACFT COLLIDED WITH TREES, THEN A UTILITY POLE, WHILE THE PLT WAS ATTEMPTING TO LAND ON A RD. THE PLT IMPLIED TO FAA & INSURANCE COMPANY PERSONNEL THAT THERE WAS NO ENG FAILURE OR MALFUNCTION.  THE DENSITY ALTITUDE WAS CALCULATED TO BE 2,000 FT.

## 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 19910626024119A](https://openairdocs.org/incident/19910626024119A), Jun 26, 1991: Scwzer G164A, Falcon, MS, Substantial damage. 676 Pounds over gross,settled after spray run hit trees and power pole. Reported both power loss and no power loss

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.
