## Analysis

THE ACFT WAS CLIMBING AS THE PLT 'FLEW UP' A GLACIER. HE STATED THAT BEFORE THE ACCIDENT, HE HAD MADE A CHECK OF THE INSTRUMENTS & OUTSIDE REFERENCES & HAD DETERMINED THAT HIS RATE OF CLIMB WAS ADEQUATE TO EASILY CLEAR THE RIDGE. HE STATED, 'THE NEXT THING I KNEW, THE PLANE HIT THE SURFACE OF THE GLACIER IN A LEVEL ATTITUDE' & NOSED OVER. THE IMPACT OCCURRED AT ABOUT 8000 FT MSL. THE ELEVATION AT THE HEAD OF THE GLACIER WAS ABOUT 9000 FT.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
