The engine anti-ice (EAI) system uses hot engine bleed air to prevent ice
on the engine cowl leading edges. The EAI system uses ice condition data
from the primary ice detection system (PIDS) to operate in the automatic
mode, or it can be manually set to on and operate continuously.

Reason for replacement: faulty unit
