What happened
The aircraft was operating during cruise flight when the engine failed. The pilot initiated a forced landing procedure directed toward a pasture area. During the descent and approach to the landing site, the right horizontal stabilizer made contact with a tree. A limb from the tree became wedged between the stabilizer and the elevator, effectively jamming the control surface in the full nose-down position.
Upon touchdown, the nose gear collapsed under the stress of the uncontrolled pitch attitude. The aircraft subsequently nosed over, coming to rest in an inverted position on the ground.
The investigation
Examination of the event revealed that the primary mechanical failure was the cessation of engine power during cruise flight. The subsequent structural damage was consistent with a high-energy impact against vegetation followed by a hard landing with compromised pitch control. The jamming of the elevator by tree debris prevented any recovery or flare maneuver prior to ground contact.
Findings
The sequence of events was driven by an initial loss of propulsion. The inability to maintain altitude necessitated an off-airport landing in terrain that contained obstacles, specifically trees. The interaction with the tree resulted in critical control surface jamming, which directly contributed to the collapse of the nose gear and the final inverted rest position of the aircraft.
Safety message
This incident highlights the critical importance of monitoring fuel quantities and planning for adequate reserves during cruise flight. Fuel exhaustion can occur without warning if management is inadequate, leaving the pilot with no option but to execute a forced landing in potentially hazardous terrain.
