## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - weather condition - high density altitude (contributing factor)
  - load jettison - not performed, pilot in command (cause)
  - landing gear,main gear - separation (contributing factor)
  - performance data - disregarded, pilot in command (cause)
  - aircraft weight and balance - improper, pilot in command (cause)
- Dragged wing,rotor,pod,float or tail/skid, descent - uncontrolled

## Analysis

THE ACFT COLLIDED WITH THE GROUND AFTER TAKEOFF AND THE LEFT MAIN GEAR WAS KNOCKED OFF. THE PLT DID NOT DUMP THE CHEMICAL LOAD WHEN THE ACFT STARTED TO SETTLE. ACCORDING TO THE PLT, THE ACFT WAS TOO HEAVY AND DENSITY ALT WAS A FACTOR.

## Other investigations on N7521Z (2)

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.
