From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On December 15, 2011, N252AL, a Cessna 206, departed homer, Alaska to pick up passengers in Nanwalek, Alaska. While on the base leg for runway 01 at Nanwalek, the airman encountered a strong head wind from the east and down draft. The runway conditions were 2-3 inches of slush with as much as 6 inches in the pot holes. Extra power was required to taxi. Prior to departure, the airman elected to back taxi to depart runway 01; this would prevent him from having to turn down wind after departure and avoid the down draft he felt on landing. This also would give him a 4 KTS tail wind component. Aircraft N252AL became airborne at approximately the half way point of the runway. The airman initiated an immediate turn over the water in order to avoid obstacles at the end of the runway. Aircraft N252AL was unable to climb and went into the water with four people on board; all four people evacuated successfully and swam to shore.
