Accident occurred Saturday, March 09, 2002 in Teterboro, NJ
Probable Cause Approval Date: 10/23/2002
Aircraft: Cessna T210N, registration: N2BS
Injuries: 1 Fatal.
NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
Several witnesses observed the Cessna T210N on initial climb, and then heard a reduction of engine power. Some witnesses thought the nose had pitched up after the power reduction, and prior to the airplane turning left and descending. The airplane banked left, descended, and struck the ground on airport property. A post-crash fire started within seconds after the airplane came to rest and consumed the cabin of the airplane. Examination of the engine revealed that the air filter element was lodged into the turbocharger air intake, and adjacent ducting. The single screen on the air filter was found on the air intake side. Installation instructions specify that with a single screen, the screen should be on the engine side of the air filter element. The air filter element had been changed during an annual inspection, about 2 1/2 months, and 30 hours prior to the accident. The specified change interval for the filter element was 12 months, 200 hours, or when the filter element was 50 % covered by foreign material. The initial emergency procedure for loss of engine power after takeoff was to maintain an airspeed of 85 knots.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: Improper maintenance by other maintenance personnel, which resulted in the air filter element being sucked into and blocking the turbocharger inlet, and a subsequent power loss. Factors in the accident were the pilot's failure to maintain airspeed and the tail wind. Full narrative available
