CHC-sjefen: - Vi har ikke tilgang til girkassen - Bergens Tidende
Short summary
Gearbox changed in January:
Ny girkasse i januar
- Vi følger et vedlikeholdsprogram som tilsier at girboksen etter 4400 flytimer sendes til en leverandør som utfører vedlikehold, sier Roland videre.
Girboksen på ulykkeshelikopteret ble installert i januar. Under vedlikehold blir enkelte deler utbedret, mens andre blir skiftet helt ut.
Roland vil ikke svare på om planetgiret, som ifølge Havarikommisjonen er utsatt for tretthetsbrudd, ble skiftet ut i januar.
- Jeg kan ikke gå inn på spesifikke opplysninger om de ulike delene.
English:
"We are following a maintenance program that demands that the gearbox after 4400 hours is sent to a supplier that performs maintenance, says Roland further.
The gearbox on the the accident aircraft was installed in January.
During maintenance some parts are improved, others are completely changed
Roland does not want to answer if the planetary gear, that according to AIBN
is exposed to fatigue crack, was changed in January.
- I cannot go into specific information about the different parts."
So from this it becomes clear that the "new" gearbox installed in January
also could be an old one with some changed parts, which makes it clear, to me, we are not speaking about a brand new unit.
If the same unit that was removed from LN-OJF, sent to maintenance and
sent back to CHC after the maintenance. Is not clear.
It is also not clear who is doing the maintenance. But I have my suspicions.
May it be also a matter of investigation what exactly was changed in the gearbox or not
