## Sequence of events

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

- Loss of control - in flight, climb - to cruise
  - weather condition - temperature extremes (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - performance data - misjudged, pilot in command (cause)
  - maneuver - performed, pilot in command (cause)
  - aircraft performance,climb capability - exceeded (contributing factor)
  - stall - not corrected, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE ACFT CRASHED SHORTLY AFTER TAKEOFF ON A VERY HOT DAY WHEN THE ACFT WAS SEEN TURNING WITH THE NOSE ELEVATED. WITNESSES NOTED A SHUDDER OF THE AIRFRAME THEN THE NOSE DROPPED. OFFICIAL TEMPERATURE WAS 106 DEGREES BUT ARPT PERSONNELREPORTED THE TEMPERATURE AS 113 DEGREES. NO MECHANICAL FAILURES OF THE ACFT AND NO MEDICAL FACTORS FOR THE PLT WERE FOUND DURING THE INVESTIGATION THAT COULD BE CONSIDERED AS CAUSAL IN NATURE. THE DENSITY ALT WAS FIGURED AT 6300 FT FOR 106 DEGREES OR 6800 FT FOR 113 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 19840704029499A](https://openairdocs.org/incident/19840704029499A), Jul 4, 1984: Cessna 150L, Henderson, NV, Destroyed, 1 fatal. High density altitude and over gross weight combined with pilots failure to maintain airspeed produced a stall.

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.
