I imagine this would be one of the rare occasions when insurance underwriters get involved with specific airline employees and I think, in this instance, the underwriters would withdraw cover for this pilot and any aircraft he flew.
The primary insurance cover may well be written by a local Indonesian company but their retention will be minimal, probably less than one percent of the total fleet value and little or nothing of the liabilities, so the vast majority of the cover will be written in the London Re-Insurance market and it is they who will call the shots.
