Except it wasn't increased to 4400hrs it was reduced to 2000hrs.
If that is the case, itīs good.
But it is truly stated in an interview with the CEO Arne Roland after CHC last week press conference that they follow a maintenance program where the gearbox at 4400 hours is sent to overhaul
here is the article
CHC-sjefen: - Vi har ikke tilgang til girkassen - Bergens Tidende
However, in the interview with NRK, BT or TU
he refuse to tell how many flying hours the gearbox had before the accident.
The main point he made several times is that CHC does not have access to the gearbox and is sent to an external supplier for overhaul.
He refuse to say where and who is doing the overhaul.
In the topic here it was mentioned that the overhaul is done by Heli-One
and is 100% owned by CHC.
Both Heli-One and CHC Headquarters are at Sola Airport in Norway.
