This is why you don't make descending turns close to the ground in whiteout conditions...

On November 14, 2008, about 1710 Alaska Standard time, a Cessna 207 airplane, N36CF, sustained
substantial damage when it collided with terrain while maneuvering for landing at Napaskiak,
Alaska. The airplane was then consumed by a postcrash fire. The airplane was being operated as a
visual flight rules (VFR) commuter flight under Title 14, CFR Part 135, when the accident occurred.
The airplane was operated as Flight 555, by Flight Alaska, dba Yute Air Alaska, Anchorage, Alaska.
The commercial certificated pilot received minor injuries. The sole passenger was not injured.
Instrument meteorological conditions prevailed in the area of the accident, and VFR company flight
following procedures were in effect. The flight originated at the Quinhagak Airport, Quinhagak,
Alaska, about 1615, and was en route to Bethel, Alaska.
During a telephone conversation with the National Transportation Safety Board (NTSB)
investigator-in-charge (IIC), on November 17, the director of operations for the operator reported
that numerous flights from Bethel had been canceled or delayed due to poor weather earlier in the
day. The weather conditions improved in the afternoon with a ceiling of about 1,500 feet, and a
visibility of 7 miles, and the pilot departed Bethel at 1452 for his first destination, Eek,
Alaska. After departure, the pilot decided not to land at his first destination because of low
visibility, and continued to Quinhagak. The pilot encountered light icing conditions while en
route, and deiced the airplane after landing at Quinhagak.
The pilot departed Quinhagak with his passenger about 1615, and told the director of operations
that the Bethel Airport was reporting a ceiling of 500 feet overcast, with a visibility of 5 miles.
After departure, the weather at Bethel deteriorated, and the pilot decided to land at Napaskiak.
While maneuvering over the Napaskiak Airport, the pilot began a descending left turn toward the
approach end of runway 02. The airplane stalled and mushed to the ground, about 250 feet short of
the runway threshold. It collided with tall brush and the ground, and a postcrash fire erupted as
the pilot and passenger were exiting the airplane.
During a telephone conversation with the NTSB IIC on November 17, the pilot reported that when he
arrived over the airport at Napaskiak, he was about 200 feet agl, and the visibility was about 1
mile. He indicated that the airplane had accumulated some ice. He said he began a left turn for the
runway, but the left wing stalled, and the airplane mushed into the ground.
The closest weather reporting facility is Bethel, which is located about 5 miles northwest of the
accident. At 1705, an aviation routine weather report (METAR) was reporting, in part: Wind, 190
degrees (true) at 8 knots; visibility, 3/4 statute mile in mist; clouds and sky condition, 500 feet
broken, 1,600 feet broken, 2,900 feet overcast; temperature, 21 degrees F; dew point, 21 degrees F;
altimeter, 29.79 inHg.
