## Probable cause

A LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON(S).

## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, landing - flare/touchdown
- On ground/water collision with object, landing - roll
  - object - building(nonresidential)

## Analysis

THE PILOT REPORTED THAT SHORTLY AFTER TAKEOFF THE RIGHT ENGINE LOST POWER. HE IDENTIFIED THAT THE RIGHT ENGINE WAS NOT PRODUCING POWER, AND USED LEFT RUDDER CONTROL AND A LEFT BANKING TURN TO MAINTAIN A COURSE AWAY FROM TREES. THE AIRSPEED WAS DECREASING, AND THE AIRPLANE WAS DIFFICULT TO CONTROL. HE DID NOT FEATHER THE RIGHT PROPELLER. WITH BOTH THROTTLES STILL FULL FORWARD, HE FEATHERED THE LEFT PROPELLER TO MAINTAIN CONTROL. DURING THE LANDING ROLL THE AIRPLANE COLLIDED WITH A SMALL METAL SHED. ENGINE TEARDOWN INSPECTION DID NOT REVEAL EVIDENCE OF A MECHANICAL FAILURE OR MALFUNCTION. DENSITY ALTITUDE WAS APRX 8,500 FT. ACCORDING TO THE OWNER'S MANUAL, UNDER THE EXISTING CONDITIONS THE AIRPLANE SHOULD HAVE BEEN ABLE TO MAINTAIN AN APRX 25 FPM CLIMB WITH THE INOPERATIVE ENGINE FEATHERED.
