## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Overrun, takeoff - roll/run
  - weather condition - tailwind (contributing factor)
  - planning/decision - poor, pilot in command (cause)
  - wrong runway - selected, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - wind information - not understood, pilot in command (cause)
  - weather condition - tailwind (contributing factor)
- Nose over, landing - roll
  - terrain condition - dirt bank/rising embankment (contributing factor)
  - aborted takeoff - delayed, pilot in command (cause)

## Analysis

A CESSNA 152 OVERRAN RWY 36 AND NOSED OVER ON THE OVERRUN AREA. THE STUDENT PLT INDICATED THAT HE ATTEMPTED THE TAKEOFF FROM MID-FIELD ON RWY 36 WITHOUT TAKING INTO ACCOUNT THE DENSITY ALT. HE ALSO STATED THAT HE ATTEMPTED TO ABORT THE TAKEOFF AFTER REACHING 40 TO 45 KTS, BUT WAS UNABLE TO STOP THE ACFT BEFORE IT OVERRAN THE RWY. THE ACFT NOSE GEAR COLLAPSED WHEN IT COLLIDED WITH A DIRT BANK AND THEN THE ACFT CAME TO REST IN A NOSE DOWN ATTITUDE. THE STUDENT PLT THEN STATED, 'THE PLANE STOPPED MOVING, BUT A STRONG TAILWIND PICKED UP THE TAIL, NOSING OVER THE PLANE, WHICH CAUSED MUCH OF THE DAMAGE.' A FAA ACCIDENT PREVENTION COUNSELOR LOCATED AT THE AIRPORT STATED THE STUDENT PLT ATTEMPTED TO TAKEOFF DOWNWIND ON RWY 36 FROM MID-FIELD. THE WINDS WERE ESTIMATED TO BE FROM THE S-SW AT 20 KTS AND THE TEMPERATURE APPROXIMATELY 90 DEG. RWY 36 IS 6,059 FT. THE COMPUTED DENSITY ALT IS APRX 5,500 FT.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19860804037479A](https://openairdocs.org/incident/19860804037479A), Aug 4, 1986: Cessna 152, Apple Valley, CA, Substantial damage. The aircraft overran the runway during an aborted downwind takeoff. The student did not compute density altitude.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
