## Probable cause

THE PILOT'S FAILURE TO MAINTAIN A PROPER ALTITUDE.

## Sequence of events

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

- Miscellaneous/other, takeoff - initial climb
  - door - open (contributing factor)
  - aircraft preflight - inadequate, pilot in command (cause)
- In flight collision with object, maneuvering
  - visual lookout - restricted (contributing factor)
  - proper altitude - not maintained, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - object - tree(s)

## Analysis

JUST AFTER LIFTOFF THE LEFT CABIN DOOR POPPED OPEN.  THE PILOT STATED THAT DUE TO THE WIND IN THE AIRPLANE HE WAS UNABLE TO LOOK UP AND OUT OF THE WINDSHIELD.  THE AIRPLANE TRAVELED TO THE SOUTH SIDE OF THE AIRPORT WHERE IT CONTACTED TREE TOPS; HOWEVER, THE PILOT WAS ABLE TO PULL UP AND KEEP THE AIRPLANE FLYING.  THE PILOT THEN FLEW ACROSS THE AIRPORT PROPERTY TO THE NORTH WHERE THE AIRPLANE JUST CLEARED A HOTEL ROOF PRIOR TO CONTACTING A TREE AND DESCENDING TO THE GROUND.  THE AIRPLANE CAME TO REST JUST OUTSIDE THE AIRPORT BOUNDARY.

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.
