| 摘要： | Narrative summary data produced by the U.S. National Transportation Safety Board (NTSB) has been obtained and analyzed for all 8,436 U.S. civil registered rotorcraft accidents which occurred from mid-1963 through 1997. This analysis was based on the NTSB's assignment of each mishap into one of 21 'first event' categories. The number of U.S. civil registered rotorcraft as recorded by the Federal Aviation Administration (FAA) for the same period has also been obtained. Taken together, these data indicate the civil rotorcraft accident rate (on a per 1,000 registered rotorcraft basis) has decreased by almost a factor of 10 (i.e., from 130 accidents per 1,000 rotorcraft in 1964 to 13.4 per 1,000 in 1997). Analysis of the mishap data indicates over 70 of the rotorcraft accidents were associated with one of the following four NTSB 'first event' categories 2408 Loss of engine power (28.5) 1,322 In-flight collisions with objects (15.7) 1,114 Loss of control (13.2) 1,083 Airframe component system failure or malfunction (12.8). |
