NSEU,
The report is official and I tend to assume they know what they are talking about up to the point I read something that looks like they don't know what they are talking about.
There were no charter ops and MAS do their own maintenance so the A1 was performed by MAS at KL (as was the overnight).
The top up is recorded as follows:
S/N 4918752 –Night Stop. Crew oxygen system pressure reads 1120 psi (EICAS).
Action taken. Crew oxygen system replenished to 1800 psi – EICAS. AMM 12-15-08 refers.
Quiet bizarrely the report states "The minimum pressure for despatch as per the MAS Minimum Equipment
List (MEL) is 310 psi at 35°C for 2-man crew and with a 2 cylinder configuration (as installed on MAS B777 fleet)."
Now, that simply beggars belief!
