Factual narrative
PLT WAS OPERATING VFR ON TOP AT 11000 FEET, COMMENCED DESCENT TO DESTINATION 34 MILES OUT. PLT RPTED FIELD IN SIGHT 16 MILES OUT, PASSING 6500 FT, CANCELLED FLIGHT PLAN. ACFT IMPACTED RIDGE AT 4100 FEET MSL 7 MILES FROM DESTINATION. DARK NIGHT CONDS EXISTED, WITH OVERCAST ABOVE BROKEN CLOUDS. RESIDENTS REPORTED MODERATE DRIZZLE IN AREA AT TIME OF CRASH. FORECAST INCLUDED MODERATE TURBULENCE BELOW 15000 FEET WITH STRONG UP AND DOWN DRAFTS NEAR MOUNTAINS, MOUNTAINS OBSCURED IN CLOUDS AND PRECIPITATION. RADAR TRACK SHOWED ACFT SPD DURING DESCENT IN EXCESS OF 200 KTS, RATE OF DESCENT UP TO 1200 FEET PER MINUTE. WRECKAGE INDICATES ACFT STRUCK STEEP ROCKY SLOPE IN NOSE-HIGH ATTITUDE WITH POWER ON.
