The the cracks were not in the horizontal stab rear spar. The inspection was of the horizontal stab attachment bracket lugs, the cracking was due to the interference fit bushes being fitted with too tight a tolerance into the lugs.
Once the fleet were modified there was never to my knowledge any more issues, although they still required inspection at an increased interval.
