## Sequence of events

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

- Airframe/component/system failure/malfunction, takeoff - initial climb
  - throttle/power lever,linkage - disconnected (cause)
- In flight collision with terrain/water, takeoff - initial climb
  - throttle/power control - improper use of, pilot in command (cause)
- Nose gear collapsed, takeoff - initial climb
  - landing gear,nose gear assembly - overload (contributing factor)

## Analysis

THE ACFT LANDED HARD AND COLLAPSED THE NOSE GEAR AFTER ONE ENGINE FAILED DURING TAKEOFF. THE ACFT HAD MADE ONE TAKEOFF AND LANDING AND WAS BEGINNING A SECOND. AS THE ACFT ROTATED THE LEFT ENGINE FAILED DUE TO THE THROTTLE LINKAGE BECOMING DISCONNECTED. THE ACFT THEN NOSED OVER AND LANDED HARD ON THE NOSE GEAR AFTER THE PILOT CUT THE POWER TO THE RIGHT ENGINE. THE PILOT WAS THROWN FORWARD AS THE ACFT NOSED DOWN AND HE INADVERTENTLY PUSHED THE RT THROTTLE. THIS ENGINE WENT TO FULL POWER AND THE PASSENGERS HAND WAS FORCED FORWARD INTO THE RT PROPELLER. HE RECEIVED SERIOUS INJURY TO HIS HAND. THE PILOT WAS NOT INJURED. THIS ACFT WAS NOT EQUIPPED WITH SHOULDER HARNESS WHICH WOULD HAVE PREVENTED THE INJURY. THE ACCIDENT POINTED OUT THE NEED AND A RETROFIT SHOULDER HARNESS WAS PROVIDED BY THE MANUFACTURER ON AN EXCHANGE OR SALE BASIS. THE ACFT IS A REGISTERED ULTRALIGHT TYPE VEHICLE.
