JACDEC

Jet Airliner Crash Data Evaluation Centre (JACDEC) is a company that provides commercial aviation safety analysis.

The company promotes the ‘JACDEC Safety Index’, a rating system developed from the company's proprietary database. The JACDEC Centre also monitors current safety occurrences and provides updates on airline safety issues on several social networks.

The ratings take into account the number and fatality rate of the hull losses (destroyed aircraft) they have suffered in the past 30 years, more recent safety data, and number of flights flown without incident. These results do not take into account the cause of the hull losses or whether the airline is at fault, so they are not a perfect measure of how safely an airline operates.
