First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
Partial loss of engine power (non-mechanical)
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary

NTSB narrative

The certificated airline transport pilot, with one passenger, was departing for another airport about 5 miles away. During the takeoff run, the engine surged. The pilot aborted the takeoff and returned to the departure point of the runway. He said he performed an engine power check which appeared satisfactory, and continued a second takeoff. The pilot did not recheck the fuel system for contamination. Following the second takeoff, the airplane climbed to about 300 feet msl, and the engine RPM suddenly dropped to idle. Emergency procedures did not restore power. The airplane collided with trees during an off-airport landing, and received impact damage to both wing fuel tanks. The airplane came to rest inverted. The pilot said he drained every fuel sump on the airplane at the beginning of the day, and again before beginning the flight to pick up the passenger. Following retrieval of the airplane, an FAA airworthiness inspector examined the airplane. He found about 1/2 cup of water in the fuel system. One wing sump drain was partially blocked by silt. With clean fuel, the engine was started and ran at an idle. The engine later produced full power on an engine test stand.

Probable cause

The pilot's inadequate preflight inspection to remove all contaminated fuel from the fuel system. Factors in the accident were the pilot's inadequate planning/decision to continue a second takeoff following an engine surge and aborted takeoff, and unsuitable terrain for a forced landing.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
