The Singapore Confidential Aviation Incident Reporting (SINCAIR): The SINCAIR programme is a voluntary, non-punitive confidential incident reporting system established by the AAIB. It provides a channel for the reporting of aviation incidents and safety deficiencies while protecting the reporter's identity.
The key objective of SINCAIR is to enhance aviation safety through the collection of feedback on incidents that would otherwise not be reported through other channels, or that may appear minor but may be useful for others to learn from the reporter's experience and may even lead to changes in procedures or design. But it does not eliminate the need for mandatory reporting of aircraft accidents and incidents to the relevant authorities under the existing law.
