It's in an EC bulletin (Safety information notice No. 2520-S-00)available to people who fly their products through the TIPI service and the text is:

It has been established that all parts of the emergency lubrication system operated within their specifications.
During examination, glycol was found throughout the gearbox casing and on all the gears and bearings, which
remained in excellent condition.
This evidence indicates that the emergency lubrication system had activated and remained operational for the
duration of the flight. Therefore, the warning of system failure indicated to the flight crew was a false alarm and resulted in the crew making the decision to perform an immediate landing, as required by the Flight Manual.
Regarding the second ditching of an EC225 in October 2012:
An emergency lubrication warning light came on and resulted in the crew making the decision to perform a
controlled ditching, as required by the Flight Manual. The Main Gearbox has arrived at EUROCOPTER‘s
Marignane facility in order to launch a deeper investigation. As already indicated in the AAIB Special Bulletin
S6/2012, the initial visual examination has identified a 360° circumferential crack on the bevel gear vertical
shaft, in the vicinity of the weld that joins two sections of the shaft.
Additionally, the initial examinations performed in EUROCOPTER under the supervision of the AAIB have
shown that glycol was found throughout the gearbox casing and on all the gears and bearings. There appears to
be no visual evidence of heat distress or damage to any of the other components in the MGB, which seems to
indicate that the EMLUB system had operated.
So helicrazi are you standing in a corrected stance?

I'm off to bed, g'night.
