The emergency lubrication system of the EC225 was modified last summer. EASA approved the changes, including replacing the air and glycol pressure switches, modifying the glycol pump and improving the system’s maintenance. The modification eliminates false alarms and cancels flight manual limitations. In other words, a crew can count on a 30-minute lubrication backup in the event of total loss of oil.
The modification approval went relatively unnoticed last year, as the focus last summer was on the shaft itself.
