According to the local media, they have grounded 2 aircraft. Others are in for inspection.
I first read this on the children's channel (you know, the one with 'airliners' in its name) yesterday morning and ran through an exercise similar to Mark's above (post #3). I too came up with similar dates/flights for the aircraft but, checking again last night and this morning, found the sky is not falling in. A good example is SQ622, shown in Mark's list as being subbed with an A330. It is at this moment airborne and is being flown by 9V-SCF.
Another example listed above is SQ672. This was flown last night by 9V-SCB, which is now flying the return leg as SQ671.
9V-SCC flew SQ876 to Taipei this morning.
