Title
In-Service Reliability Data of Continuously Active Ballscrew and Geared Flight Control Actuation Systems
Scope
An industry survey has been completed to determine the incidence of jam and excessive backlash in rotary and linear mechanical actuators subject to "primary flight control like" duty cycles. The data is valuable for understanding how existing mechanical actuators behave in service, identifying areas for potential improvement and possibly being used as a reference to support future primary flight control system trade-off studies.
Rationale
Need to update the data base from the last years. As agreed during preparation session, only the THSA data will be updated.
