From the Wikipedia article
The Necon Air Cessna 208 accident occurred on 18 January 1999. On that day, a Cessna 208A Caravan I of Necon Air, which was to fly from Jumla to Nepalganj, crashed shortly after takeoff from Jumla Airport. Five of the twelve people on board died in the accident.
Accident sequence
After takeoff the aircraft climbed very steeply to 450 feet (approx. 140 metres). It then stalled and crashed to the ground with a left roll angle and caught fire. The fire could not be extinguished because no firefighting equipment was available on site. The portable fire extinguisher in the Jumla control tower was still in its original packaging.
Investigation and cause
Cause
The accident investigators determined the probable cause of the accident to be the captain's failure to configure the aircraft properly for takeoff. By all appearances, the flight crew had not worked through the pre-takeoff checklist properly and let the aircraft roll for takeoff with the high-lift devices fully extended. The incorrect configuration of the high-lift devices was said to have subsequently led to a premature steep climb, which ended in a stall that occurred at an altitude from which the aircraft could no longer be recovered.

Source notes (4)
- One occurrence in two sources, merged: the Wikipedia article "Necon Air Cessna 208 accident" and NTSB case DCA99RA033, matched by the same aircraft maker and place and date. For this event outside the United States Wikipedia's values are used where the two differ; each value names its source.
- Death toll settled: the NTSB record (DCA99RA033) gives 4 and the Wikipedia article 5; Civil Aviation Authority of Nepal (CAAN) aeroplane accident list, entry 20 (9N-ADA, Jumla) gives 5. CAAN: 5 fatalities, 7 survivors (12 aboard). ASN reports 4 passengers + 1 crew. NTSB's 4 matches early press (Flight International, 27 Jan 1999: '4 killed'). It is an early count, possibly missing a later death, which could not be confirmed.
- The NTSB record dates it 1999-01-17 and the Wikipedia article 1999-01-18; Wikipedia's date is used.
