AC Ovee,
The incident report shows that extensive investigation was carried out on XV235 whilst on the ground at Kandahar. On completion of this work the ac was released only for a ferry flight to the DOB, for further investigation.
This would seem to indicate that the engineering authority, IPT and ADA were not as confident as you that the event was quite so benign.
From a CRM perspective, it would be fascinating to hear a tape of a Nimrod captain proposing to continue the sortie under such circumstances.
