Cessna 206.
Prelim report (no injuries).

While maneuvering through a mountain pass on 11-02-10, a Cessna 206B was the 2nd aircraft in a flight of 2 attempting to land on a mountain airstrip. According to the NTSB report, the pilot stated while turning from base to final, the aircraft had to be maneuvered through 2 steep rock cliffs to line up for final. While in the turn, the pilot allowed the turn to widen out which resulted in the nose and right main gear contacting the cliff face. The impact caused the tire to separate from the nose gear strut and the complete loss of the right main gear assembly. To have emergency equipment available for the landing, the pilot flew the accident aircraft to U70 (Cascade ID) and decided to land on the grass area adjacent to the runway. During the landing the nose gear dug into the soft grass and the aircraft flipped over onto its back.

On 12-07-10, NTSB released its finding on a helicopter accident which occurred on 08-05-08, near Weaverville CA, when a Sikorsky S61N under contract with the US Forest Service (USFS) collided with trees after departing a 6000-ft msl site while transporting firefighters.
NTSB stated there was a series of improper actions by the contractor and USFS which led to the accident, including intentional alteration of weight documents, performance charts and unapproved performance calculations.
