## Probable cause

THE PILOT-IN-COMMAND'S CONTINUED FLIGHT INTO ICING CONDITIONS AND HIS FAILURE TO USE THE AIRPLANE'S ANTI-ICE/DE-ICE SYSTEM RESULTING IN A BUILD-UP OF ICE OVER THE AIRPLANE'S SURFACE AREA AND RESULTANT LOSS OF CONTROL. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE: THE AIRPLANE WAS OVER IT'S CERTIFICATED MAXIMUM GROSS WEIGHT, AND THE ICING CONDITIONS.

## Sequence of events

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

- Loss of control - in flight, approach - iaf to faf/outer marker (ifr)
  - aircraft weight and balance - exceeded, pilot in command (contributing factor)
  - weather condition - icing conditions (contributing factor)
  - flight into known adverse weather - continued, pilot in command (cause)
  - wing - ice (cause)
  - anti-ice/deice system - not used, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

DURING THE WX BRIEFING AT CHICAGO, THE PILOT WAS PROVIDED PILOT REPORTS OF AIRCRAFT ENCOUNTERING ICING IN THE VICINITY OF CHICAGO, WEST CHICAGO, AND SPRINGFIELD. HE WAS ALSO GIVEN THE DESTINATION SURFACE TEMP/DEWPOINT OF 33/31. WHILE BEGINNING THE APPROACH TO THE DESTINATION AIRPORT, AT AN INITIAL APPROACH ALTITUDE OF 2,400 FT, THE FRONT LEFT SEAT PILOT STATED SHE OBSERVED ICE ON THE WINDSHIELD AND WINGS. IN ADDITION, THE REAR LEFT SEAT PAX STATED THAT SHE REMEMBERS THE REAR RIGHT SEAT PAX/PILOT LOOKING AT THE WINGS WITH A FLASHLIGHT, AND RECALLED OBSERVING 'ICE CURVED OVER THE TOP OF THE WING...'. THE AIRPLANE IMPACTED THE GROUND IN AN UNCONTROLLED DESCENT. THE AIRPLANE WAS APRX 245 LBS OVER MAX GROSS WEIGHT WHEN THE ACCIDENT OCCURRED.

## Other investigations on N345CC (1)

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.
