AIR TRANSPORT - MAS Admits maintenance lapse after 777 suffers double engine
trouble
Flight International Online News (24Dec99)
Malaysia Airlines (MAS) has admitted that a maintenance lapse was
responsible for the emergency landing of a Boeing 777-200 suffering low oil
pressure on both its Rolls-Royce Trent 800s.
Flight MH137, operating from Kuala Lumpur, Malaysia, to Auckland, New
Zealand, on 4 December, was forced to return to Kuala Lumpur International
Airport after the captain noticed a gradual oil-pressure drop in both
powerplants.
MAS says: "A technical inquiry has established that the engines were losing
oil pressure from a breather vent tube on each engine, which were
disconnected for maintenance. A lapse in hand-over between the shifts had
led to the vent tubes remaining unconnected. An engine test run was
conducted after maintenance. No oil leak was detected until the flight was
despatched."

This is about as close to a sin-bin offence for a failure to meet ETOPS
standards that an airline can approach without heavy fines and a loss of
certification. If either engine had failed due to this problem I daresay
we'd be talking about how Malaysia lost the right to fly 180 minutes
ETOPS....

> A recent B777 in flight shutdown was filed by SIA management as "pre-cautionary" Investigations revealed that there was little oil left in the engine, as most had been ejected over the Bay of Bengal. Non compliance by the crew to shut the offending engine down, would have resulted in a severe case of the shakes!
If it had been correctly filed as an required in flight shutdown,then SQ may have had problems with its 207 mins ETOPS over the pacific.Urm, would you fly here?? Do pax care? Does anybody?

Oil does seem to be rather a worrisome problem with SIA. After all the expat engineers left a few years ago, management decided to employ main-land Chinese engineers to make up the numbers. During routine maintance of one of their A310 one of these new boys did an oil change and filled the engine up with hydraulic fluid. The aircraft subsequently had an engine failure after take off.
Lucky the same guy didn't do the other engine. ETOPS policy I hope?
Amazing stuff, but it happened.
