Narrative:Twin Otter N203E departed Sullivan Regional carrying seven skydivers. Immediately after takeoff from runway 06 witnesses heard a popping sound. The Twin Otter lost height, contacted a utility pole, a tree and crashed next to a house at 1039 North and South Road, just northwest of the airport.
Probable Cause:
PROBABLE CAUSE: "The National Transportation Safety Board determines that the probable cause of this accident was the pilots failure to maintain airspeed following a loss of power in the right engine due to the fracturing of compressor turbine blades for undetermined reasons. Contributing to some parachutists injuries was the lack of a more effective restraint system on the airplane."

Follow-up / safety actions
NTSB issued 4 Safety Recommendations
Issued: 25-SEP-2008 | To: FAA | A-08-71 |
Conduct research, in conjunction with the United States Parachute Association, to determine the most effective dual-point restraint systems for parachutists that reflects the various aircraft and seating configurations used in parachute operations. (Closed - Acceptable Action) |
Issued: 25-SEP-2008 | To: FAA | A-08-72 |
Once the most effective dual-point restraint systems for parachutists are determined, as requested in Safety Recommendation A-08-71, revise Advisory Circular 105-2C, Sport Parachute Jumping, to include guidance information about these systems. (Closed - Acceptable Action) |
Issued: 25-SEP-2008 | To: U.S.Parachute Association | A-08-73 |
Work with the Federal Aviation Administration to conduct research to determine the most effective dual-point restraint systems for parachutists that reflects the various aircraft and seating configurations used in parachute operations. (Closed - Acceptable Action) |
Issued: 25-SEP-2008 | To: U.S.Parachute Association | A-08-74 |
Once the most effective dual-point restraint systems for parachutists are determined, as requested in Safety Recommendation A-08-71, educate your members on the findings and encourage them to use the most effective dual-point restraint systems. (Closed - Acceptable Action) |
