## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command
- In flight collision with object, landing - roll
  - object - aircraft parked/standing

## Analysis

ACCORDING TO THE PLT, A POST MAINTENANCE TEST FLT WAS PERFORMED ABOUT 45 MINS BEFORE THE LANDING OCCURRED. THE PLT STATED THAT HE ALLOWED THE RIGHT SEAT PASSENGER A STUDENT PLT AND OWNER OF THE CESSNA 170, TO FLY AND LAND THE ACFT. UPON LANDING THE PLT NOTICED THE NOSE OF THE ACFT WAS NOT HIGH ENOUGH AND REMINDED THE PASSENGER THAT HE WAS FLYING A TAIL DRAGGER. THE ACFT WAS HOPPING BUT UNDER DIRECTIONAL CONTROL. THE ACFT VEERED TO THE RIGHT FOLLOWED BY A GROUND LOOP. POWER WAS APPLIED AFTERWARDS BY THE PASSENGER AND THE ACFT COLLIDED WITH A PARKED GLIDER ACFT.
