The third black box

The third black box - registering vibrations of the engine - will be examined in Poland because it was invented by Polish engineers. - Third recorder, which was sent for examination to Poland, monitors and records, in addition to the standard FDR, the vibration on the engine bearings and suspension.

This monitoring and recording system was developed for, and installed on the
notorious Soloviev engines by the Polish engineers after the accidents
of the Il-62, using the same engines as tu-154.

The system was supposed to detect and register any abnormalities in the
turbine parameters to prevent and avoid the uncontained engine failures, for which
the engines were notorious.
