NTSB: Ice protection not on when plane crashed into house
BALTIMORE (AP) — The ice protection system was not activated on a business jet that crashed into a Maryland house, killing six people, even though the air temperature was near freezing, according to a federal safety investigation released Wednesday.
A review of the airplane's flight data recorder found that the ice protection system was not activated at the time of the crash.
The final outside air temperature recorded by the recorder was 1.75, degrees Celsius, or about 35.15 degree Fahrenheit.
