Cessna 414 Safety Record

the pilot's disregard for an in-flight weather advisory, his likely encounter with marginal VFR or IMC weather conditions, his decision to continue flight into those conditions, and failure to maintain an adequate terrain clearance altitude resulting in an in-flight collision with trees and mountainous terrain. A contributing factor was the pilot's failure to adhere to the VFR weather minimum procedures in the company's Operations Manual.

The pilot's failure to maintain airspeed while maneuvering in icing conditions on a circling approach for landing resulting in an inadvertent stall and collision with trees and terrain. A factor in the accident was a partial loss of engine power due to the pilot's failure to activate the alternate induction air system, and exceeding the maximum landing weight of the airplane.

The failure of the pilot to maintain airspeed (Vs) following a total loss of engine power from the right engine due to fuel starvation, resulting in an inadvertent stall, uncontrolled descent, and in-flight collision with trees and terrain. Factors in the accident was the failure pilot to feather the right propeller following the total loss of engine power, and his lack of total experience in the accident make/model of aircraft.

The flight instructor's improper selection of the high boost position for the operating right engine while on base leg to land, which resulted in a loss of engine power of the right engine. Factors associated with the accident are the left engine's loss of power for an undetermined reason, the flight instructor's failure to feather the propellers of the affected engines, and his failure to maintain directional control, which resulted in an off-airport forced landing.

the inadequate in-flight emergency planning/decision, the checklist not followed and excessive approach altitude by the pilot. Contributing factors were the loose oil return line and weather.

The pilot's failure to maintain adequate airspeed (Vmc) which resulted in a loss of control. Contributing factors were the improper in-flight planning/decision not to land at a closer airport and the lack of recent experience in multiengine airplanes by the pilot-in-command, the cylinder head separation, the inadequate manufacturing process, and the lack of continued airworthiness instructions relating to the Riley Super-8 STC.

The pilot not maintaining the proper airspeed during the circling approach, the inadvertent stall and the subsequent loss of control. Factors were the pilot's decision to continue the approach in weather conditions below the approach/landing minimums, the continued flight below the minimum descent altitude, the pilot not following the approach airspeed listed in the owner's manual, the air traffic controllers not issuing weather information to the pilot, and the weather conditions.

The pilot's physical impairment due to the cumulative effects of carbon monoxide from engine exhaust by-products, carbon monoxide from heavy tobacco use, and the loss of an undetermined amount of cabin pressurization. A factor in the loss of pressurization was a fractured clamp.

The failure of the pilot-in-command to ensure adequate airspeed for flight during a forced descent due to airframe icing, resulting in a stall. Factors included: freezing rain conditions, airframe icing, an improper decision by the pilot-in-command to turn toward mountainous terrain (where a turn toward lower and level terrain was a viable option), mountainous terrain, and insufficient altitude available for stall recovery.

The pilot's improper use of the emergency fuel boost pump, which resulted in excessive fuel flow to the engine and subsequent total loss of left engine power. Factor's were the high density altitude, the pilot exceeding the airplane's weight and balance, the partial loss of left engine power as a result of the faulty magnetos, and the pilot's inadequate preflight inspection by not performing an engine run-up.

The failure of the right main landing gear torque tube support bracket/pivot bearing which resulted in the failure of the landing gear locking mechanism.

The pilot's failure to maintain control of the airplane after an undetermined failure of the airplane's attitude indicator. A factor in this accident was fog.

the slipped number two bearing in the airplane's right engine, which blocked the bearing's oil feed line, causing the bearing and the crankshaft to overheat and fracture. A factor contributing to this accident was the trees.

Inadequate maintenance of the cabin pressurization system, which resulted in inadequate pressurization and incapacitation of the pilot due to the hypoxia. Also causal was the pilot's failure to adequately monitor the cabin pressurization system.
