## 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
  - terrain condition - high terrain (contributing factor)
  - weather condition - high density altitude (contributing factor)
  - terrain condition - mountainous/hilly (contributing factor)
  - flight controls - improper use of, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

SHORTLY AFTER TAKEOFF, PRIOR TO REACHING 500 FEET AGL, THE PILOT LOST CONTROL OF THE AIRCRAFT AND STRUCK TREES. AFTER STRIKING TREES THE AIRCRAFT THEN IMPACTED THE GROUND AND EXPLODED INTO FLAMES. WITNESSES STATED THAT FROM THE TIME OF ROTATION TO THE TIME CONTROL WAS LOST IN-FLIGHT AN EXTREME NOSE HIGH ATTITUDE WAS MAINTAINED. WITNESSES STATED THAT THEY SAW THE LEFT WING DROP, AS IF THE PILOT HAD MADE AN INTENTIONAL LEFT TURN OR THAT A DEPARTURE STALL HAD OCCURRED. THERE WAS A SEVERE POST-IMPACT FIRE ALONG WITH DESTRUCTION OF THE AIRCRAFT'S SYSTEMS. THE AIRCRAFT'S ENGINE AND TURBOCHARGING SYSTEM WAS EXAMINED AND TORN DOWN WITH NO ABNORMALITIES FOUND. NO MECHANICAL REASON FOR THE NOSE HIGH ATTITUDE OR LOSS OF CONTROL IN-FLIGHT COULD BE DETERMINED. AIRSTRIP ELEV WAS 5650 FEET, AND DENSITY ALT ABOUT 7000 FEET.  THE AIRCRAFT'S WEIGHT WAS BELOW MAX GROSS WEIGHT AND CG WAS WITHIN LIMITS.  THIS WAS THE SECOND FLIGHT OF THE DAY FOR THE PILOT AND PAX.

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.
