I have just read the January CAA Ocurrence Report Digest and was struck by this Dauphin N3 report:
Following a normal start and lift into hover, the nr2 engine flamed out during transition to forward flight. The a/c landed without incident and a visual inspection found no damage. Engines restarted and flight resumed with no recurrence.
However, later in the day, when starting the nr1 engine, the 30 second 'OEI Hi' light was observed flashing.
Subsequent engineering investigation, including full borescope inspection of the nr2 engine, found no defects or damage. The manufacturer was contacted about the 'OEI Hi' light and a NTO was issued
I'm curious by the notion that one would simply start up and continue as if nothing had happened - engines don't just flame out.
I'm curious that it was not assumed that 30 second power had been used - it would generally be accepted as being if an engine fails in a high power situation (such as taking off.)
Does the N3 have the Arriel 2C2, or the 2C1? If the latter then surely a module 3 and 4 change was required, or has the maintenance procedure been amended since its introduction - previously there was no cumulative 30 second power useage allowed, inspection or otherwise.
Strange how such events can hide innocuously amongst the "manifest in error by 20 kg" or "spurious chip warning" type reports, without further comment or remark.
