NTSB narrative

THE STATE-OPERATED AMPHIBIAN WAS UNABLE TO OUTCLIMB RISING TERRAIN AND IMPACTED THE MARGERIE GLACIER, COMING TO REST AT 9,650 FT MSL. PILOT HAD NOT FLOWN SINCE LAST PROFICIENCY CHECK ON 11/27/93. PILOT'S CHECKS WERE CONDUCTED BY A CIVILIAN EMPLOYEE WHO REPORTED DIRECTLY TO THE PILOT. PILOT DID NOT PERFORM WEIGHT & BALANCE. AIRPLANE 1,403 LBS OVER MAX GROSS WEIGHT. ADDITIONALLY, 80 LBS OF FROZEN WATER WAS FOUND IN THE BILGES OF THE HULL. AT THE POWER AND CARB AIR TEMP SETTINGS USED BY THE PILOT, THE AIRPLANE REACHED MAX PERFORMANCE AT APRX 5,000 FT MSL. INVESTIGATION DELEGATED TO THE U.S. BY CANADA.

Probable cause

THE PILOT'S IMPROPER DECISION IN ATTEMPTING TO OUTCLIMB THE RISING TERRAIN WITH THE EXISTING AIRPLANE CLIMB PERFORMANCE. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE PILOT'S INADEQUATE PREFLIGHT OF THE AIRPLANE, THE OVER MAXIMUM GROSS WEIGHT OF THE AIRPLANE, HIGH TERRAIN, HIGH DENSITY ALTITUDE, THE PILOT'S LACK OF RECENT FLYING EXPERIENCE, HIS OVERCONFIDENCE IN HIS AIRMANSHIP ABILITY, QUESTIONABLE TESTING OF THE PILOT'S FLYING COMPETENCY AND PROFICIENCY, AND THE STATE OF ALASKA'S INADEQUATE OVERSIGHT OF THE AVIATION PROGRAM WHICH ALLOWED MANAGEMENT TO DISREGARD THEIR OWN REGULATIONS.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
