Contributing to the accident was the pilot’s inability to respond appropriately to the emergency due to impairment from his previous use of cocaine and multiple other impairing drugs.

The pilot’s inadequate preflight fuel planning, which resulted in a total loss of engine power due to fuel exhaustion and a forced landing.
