The pilot reported that shortly after takeoff, while in the initial climb, the airplane developed a high sink rate. The pilot stated he increased power and jettisoned the load, however, the airplane continued to sink eventually impacting terrain, in a level flight attitude, approximately 1.5 miles north of the airport. The pilot stated he departed the runway with a "slight quartering tailwind." The operator reported that the airplane was loaded with approximately 2,000 pounds of dry fertilizer and approximately 55 gallons of Jet A. The field elevation at the departure airport is 4,048 feet above mean sea level (msl). The estimated density altitude (DA) was approximately 5,584 feet. The operator reported that there were no mechanical malfunctions or failures with the airplane prior to the accident.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: Failure to maintain clearance from terrain during takeoff and initial climb. A high density altitude was a factor. Full narrative available
