Détails:
A Cessna 208B Grand Caravan, N126AR, operated by Hageland Aviation Services impacted terrain in the Three Steps Mountain area about 60 km southeast of Bethel, Alaska. A post-crash fire erupted. Both pilots were killed.
The flight was intended to be the first training flight of the newly hired second-in-command (SIC) pilot. The SIC was operating from the airplane's right seat during the training.
The airplane departed Bethel Airport, Alaska, at 15:35. After departure, the airplane began a series of training maneuvers, consistent with normal operations. About 21 minutes into the flight, when the airplane was about 3,400 ft mean sea level, it began a steep descent and subsequently impacted terrain. An airplane performance study showed that the airplane reached a nose-down pitch of about -40 degrees and that the descent rate reached about 16,000 ft per minute.
The NTSB determined that it is likely that the check airman simulated a pitch trim excursion and that the trainee, who lacked experience in the airplane type, did not appropriately respond to the excursion. The check airman did not take remedial action and initiate the recovery procedure in time to prevent the control forces from becoming unmanageable and to ensure that recovery from the associated dive was possible.
The aircraft impacted frozen tundra and came to rest in an area of heavy willows.

Probable Cause:

PROBABLE CAUSE: "The check airman's delayed remedial action and initiation of a recovery procedure after a simulated pitch trim excursion, which resulted in a loss of airplane control."
