  - weather condition - rain (contributing factor)
  - weather condition - temperature extremes (contributing factor)
  - weather condition - icing conditions (contributing factor)
- Loss of control - in flight, cruise - normal
  - flight control,elevator tab - frozen (contributing factor)
  - flt control syst,elevator trim/tab control - movement restricted (contributing factor)
  - elevator trim - not possible, pilot in command (contributing factor)
- In flight collision with object, approach - faf/outer marker to threshold (ifr)
  - terrain condition - high obstruction(s)
  - ifr procedure - improper, pilot in command (cause)
  - object - electrical tower
  - decision height - below, pilot in command (cause)
  - missed approach - initiated, pilot in command
- Nose gear collapsed, landing - flare/touchdown
  - landing gear,nose gear - previous damage (cause)
  - landing gear,nose gear - unlocked (cause)

## Analysis

WITH OAT 25 DEGREES BELOW ZERO AND THE AIRCRAFT FLYING THROUGH HEAVY RAIN THE PILOT REPORTED THE ELEVATOR TRIM TAB BECAME INOPERATIVE. WHILE ATTEMPTING TO STABILIZE THE AIRCRAFT MANUALLY DURING AN ILS APPROACH THE AIRCRAFT DESCENDED BELOW GLIDESLOPE AND COLLIDED WITH A 35 FOOT TV ANTENNA 2 TO 3 MILES FROM THE RUNWAY. THE PILOT EXECUTED A MISSED APPROACH AND EVENTUALLY ELECTED TO FLY TO HIS ORIGINAL ALTERNATE, COLUMBUS. ON FINAL, THE TOWER PERSONNEL OBSERVED THE NOSE GEAR NOT FULLY EXTENDED AND NOTIFIED THE PILOT. BOTH ENGINES WERE FEATHERED AND UPON TOUCHDOWN THE NOSE GEAR COLLAPSED. INVESTIGATION REVEALED N3DS HAD BEEN CLEARED FOR A DME/ILS TO 7000 FEET BUT NO FINAL APPROACH CLEARANCE HAD EVER BEEN ISSUED.

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.
