Incident Overview
A solo commercial pilot operating an air taxi/cargo flight departed from a remote airport. Shortly after takeoff, during the cruise climb phase, the aircraft's engine began to run rough and lose power. The pilot executed emergency engine procedures, but these did not rectify the roughness or restore power.
Forced Landing and Damage
The pilot conducted a forced landing in a marshy, muskeg-covered area. Upon landing, the aircraft sustained substantial damage to both wings, the engine firewall, and the fuselage.
Post-Recovery Examination
After the aircraft was recovered, an FAA airworthiness inspector examined the engine. The inspection did not reveal any mechanical malfunction that could explain the power loss.
