## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - nonmechanical, approach
  - preflight planning/preparation - inadequate, pilot in command (cause)
  - engine instruments,fuel quantity gage - false indication (contributing factor)
  - fluid,fuel - exhaustion (cause)
  - fuel supply - inadequate, pilot in command (cause)

## Analysis

DURING AN APCH, THE RIGHT ENG LOST POWER, BUT AN UNEVENTFUL LANDING WAS MADE. AN EXAM REVEALED THE AFT FUEL TANK, CONSISTING OF THE #3 & #4 FUEL CELLS, WERE EMPTY, ALTHOUGH THE FUEL QUANTITY GAGE INDICATED 500 LBS OF FUEL REMAINING. THE ERRONEOUS READING WAS TRACED TO THE FUEL PROBE CANNON PLUG, PN 1-332-1, WHICH WAS SOAKED WITH DEICE FLUID/GLYCOL.
