TOTAL FAILURE OF THE ENGINE CONNECTING ROD.

## Sequence of events

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

- Loss of engine power(total) - mech failure/malf, cruise - normal
  - engine assembly,connecting rod - failure,total (cause)
- Forced landing, descent - emergency
- Hard landing, landing - flare/touchdown
  - airport facilities,runway/landing area condition - congested (contributing factor)
  - procedures/directives - not followed, pilot of other aircraft (contributing factor)
  - object - aircraft moving on ground (contributing factor)
  - planned approach - not possible (contributing factor)
  - visual lookout - inadequate, pilot of other aircraft (contributing factor)
  - landing gear,nose gear - collapsed
  - maneuver - abrupt, pilot in command (contributing factor)

## Analysis

DURING THE LOCAL FLIGHT OF THE EXPERIMENTAL AIRPLANE, A CONNECTING ROD BROKE IN THE ENGINE. THE PILOT WAS ABLE TO MAKE IT BACK TO THE AIRPORT FOR A FORCED LANDING BUT WAS UNABLE TO LAND ON THE RUNWAY DUE TO ANOTHER AIRPLANE THAT TAXIED ONTO THE RUNWAY IN FRONT OF THE APPROACHING AIRPLANE. THE AIRPLANE MADE AN OFF-RUNWAY, HARD LANDING, AND BOTH LANDING GEARS COLLAPSED. THE PLT DID NOT FILE AN ACC REPORT.

## Other investigations on N47SV (1)

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.
