Circumstances:
The airplane impacted a ridgeline about 1.5 miles from the runway and approximately 7 to 14 seconds after the pilot reported a dual engine flameout. The airplane's altitude was about 400 feet agl when the pilot reported the flameout. The inspection of the airplane revealed no preexisting anomalies. Icing conditions were forecast and PIREPS indicated that light to moderate rime/mixed icing conditions existed along the route of flight. The Continuous Ignition switches were found in the OFF position. The Approach procedures listed in the Airplane's Flight Manual stated, 'CONTINUOUS IGNITION SHALL BE SELECTED TO ON DURING APPROACH AND LANDING WHILE IN OR SHORTLY FOLLOWING FLIGHT IN ACTUAL OR POTENTIAL ICING CONDITIONS.' The aircraft manufacturer had issued a Service Bulletin in 1995 for the installation of an auto-ignition system to '... reduce the possibility of engine flame-out when icing conditions are encountered and the continuous ignition is not selected.' The operator had not installed the non-mandatory service bulletin. On May 5, 2000, the FAA issued an Airworthiness Directive that required the installation of an auto-ignition system. The toxicology test detected extremely high levels of dihydrocodeine in the pilot's blood. The pilot received a special issuance second-class medical certificate on August 22, 1995, after receiving treatment for a self disclosed history of drug abuse. The drug testing that this pilot underwent as a consequence of his previous self disclosed history of drug abuse would not have detected these substances.
Probable cause:
The pilot failed to follow the flight manual procedures and did not engage the Continuous Ignition system resulting in both engines flaming out when the air induction system was blocked with ice. Additional factors to the accident included the hilly terrain, the icing conditions, and the operator not complying with a Service Bulletin for the installation of an auto-ignition system.

Aircraft flight hours:

Circumstances:
The flight took off at 0500 hours in dark visual meteorological conditions. Radar data indicates that the flight was heading in an easterly direction, towards its destination and had climbed to and leveled off at 12,500 feet. Three minutes prior to the last identified radar target, the pilot obtained a partial weather briefing, for the destination airports, from the flight service station. The wreckage was located in an area of high mountainous terrain. Evidence indicated that the flight collided with a ridge line at the 12,400 foot level. The main wreckage was located on the east side of the ridge at 11,400 feet. During the post crash investigation, there was no evidence of a mechanical failure or malfunction. Both occupants were killed.
Probable cause:
Poor inflight planning/decision. Factors to the accident were: dark night condition and terrain clearance was not maintained.
