Probable cause

The pilot's failure to properly execute a precautionary approach following an engine failure.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(partial) - mech failure/malfApproach - vfr pattern - downwind
Forced landingManeuvering - turn to landing area (emergency)
In flight collision with terrain/waterLanding

Analysis

While conducting a test flt following overhaul of both engines the rear engine failed while on downwind leg. The plt secured the engine and attempted to feather the prop. The prop would not feather. The plt overflew an available runway while conducting a precautionary approach and overshot the runway of intended landing. The acft landed in a runup area adjacent to the runway in a high rate of descent and came to rest in a grass area between the runway and taxiway. The acft sustained substantial damage and the plt and pax were not injured. The engine failed due to the oil dilution line being connected to the pressure port on the oil pump instead of the vacuum port, and maintenance instructions do not provide guidance for the installation.
