Hi there Mo
Depends what exactly the report is about with regards EICAS and how long it needs to be. EICAS system (Engine Indicating and Crew Alerting System) was introduced in the Boeing 757 and 767.
Maybe include the differences between EICAS and ECAM and talk about how EICAS highlights messages in priority order (text colour changes).
Rockwell Collins website has a bit of info on the system. Otherwise Google is probably your best friend if you don't have any e-manuals available.
I doubt there is too much literature in the public domain specifically about the system, at least not much more than you can achieve through Google.
P.s - if you want to be an LAE maybe you should jump ship to an airline maintenance organisation. Would be more relevant to defect fixing and rectification than a manufacturer I'd have thought ?
Safe flying
