Safety Recommendation A-81-024
Details
Synopsis: ON JULY 21, 1980, SCENIC AIRLINES FLIGHT 306, A CESSNA 404, N26835, CRASHED DURING TAKEOFF FROM THE GRAND CANYON NATIONAL PARK AIRPORT, TUSAYAN, ARIZONA. THE LEFT ENGINE TURBOCHARGER FAILED AFTER TAKEOFF CAUSING A SUBSTANTIAL POWER LOSS. THE AIRCRAFT WAS NOT ABLE TO CLIMB OR MAINTAIN ALTITUDE BECAUSE THE PILOT FAILED TO ESTABLISH IMMEDIATELY A MINIMUM DRAG CONFIGURATION WHICH FURTHER DEGRADED THE AIRCRAFT'S PERFORMANCE SIGNIFICANTLY. THE AIRCRAFT WAS 856 LBS BELOW ITS CERTIFICATED MAXIMUM GROSS TAKEOFF WEIGHT AND WAS WITHIN C.G. LIMITS; HOWEVER, THE DENSITY ALTITUDE AT THE TIME OF TAKEOFF WAS 10,000 FEET M.S.L. THE PILOT AND SIX OF THE SEVEN PASSENGERS WERE KILLED. ONE PASENGER SURVIVED THE ACCIDENT BUT DIED 5 DAYS LATER BECAUSE OF THERMAL INJURIES. EXCEPT FOR THE POSTCRASH FIRE, THE ACCIDENT WAS SURVIVABLE.
Recommendation: THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: REQUIRE THAT PILOT TRAINING PROGRAMS FOR 14 CFR 135 CERTIFICATE HOLDERS WHICH OPERATE LIGHT TWIN-ENGINE AIRCRAFT INCLUDE SPECIFIC GROUND AND FLIGHT TRAINING IN: (1) THE FACTORS RELATED TO ACHIEVING AND MAINTAINING VYSE; (2) THE CAPABILITY OF COMPANY AIRCRAFT TO MAINTAIN LEVEL FLIGHT AT AIRSPEEDS BELOW VYSE WHILE IN A SINGLE-ENGINE CONFIGURATION; (3) THE CAPABILITY OF COMPANY AIRCRAFT TO ACCELERATE THE VYSE WHILE IN A SINGLE-ENGINE CONFIGURATION; AND (4) RAPID APPRAISAL OF THOSE SITUATIONS IN WHICH A CONTROLLED, STRAIGHT-AHEAD EMERGENCY LANDING IS THE SAFEST OR ONLY OPTION AVAILABLE.
