Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Initial climb
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
Loss of control in flight
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
Stall/mush; Tree(s)
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Destroyed

Cause areas

  • Pilot in command › Airspeed, not attained
  • Pilot in command › Rotation, excessive

NTSB narrative

WITNESSES REPORTED THAT THE AIRCRAFT LIFTED OFF RUNWAY 8 IN AN UNUSUALLY NOSE-HIGH ATTITUDE WITH A SHALLOW CLIMB ANGLE. THE AIRCRAFT CONTINUED ON THE RUNWAY HEADING UNTIL IT SETTLED INTO A GROUP OF TREES 0.4 MILES FROM THE END OF THE RUNWAY. THE AIRCRAFT OWNER'S MANUAL INDICATED THE DISTANCE REQUIRED TO TAKE OFF AND CLEAR A 50-FOOT OBSTACLE UNDER NO WIND CONDITIONS WOULD BE APPROXIMATELY 4,700 FEET. THE 5,850-FOOT-LONG, HARD-SURFACED RUNWAY HAS A SLIGHT RISE IN THE CENTER, BUT OTHERWISE HAS NO SLOPE. WINDS WERE 7 KNOTS FROM 080 DEGREES. WING FLAPS WERE NOT UTILIZED. THE STAND OF TREES OFF THE END OF THE RUNWAY WAS BETWEEN 25 TO 35 FEET IN HEIGHT AND SITUATED ON SLIGHTLY RISING TERRAIN. NO SIGNIFICANT DISCREPANCIES WERE NOTED IN THE EXAMINATION OF THE ENGINE OR AIRFRAME. THE SAFETY BOARD CONCURS WITH THE TECHNICIAN THAT THE ABNORMALITY FOUND IN THE CARBURETOR HAD NO ROLE IN THE CAUSE OF THIS ACCIDENT. THE AIRPORT ELEVATION IS 6,750 FEET AND THE TEMPERATURE WAS ABOUT 51 DEGREES. THE DENSITY ALTITUDE WAS CALCULATED TO BE 7,600 FEET.

Probable cause

the pilot's initial overrotation, his failure to attain the proper climb airspeed, and an inadvertent entry into a stall mush condition. A factor in the accident was the high-density altitude.

  • 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.
