Looks like another CF6-50 has blown up. The original NTSB recommendation called for borescoping every 20ish hours. The FAA changed that to 75ish, but of course I would never suggest that was in any way as a result of commercial pressure. The ACT A300 which blew a donk in BAH had been borescoped 50ish hour prior to blowing up; it will be interesting to see when the last borescope of this engine took place.
Affected aircraft are the 747, DC-10 and A300 which, as we all know, are mainly being used as freighters.GE have no intention or plans for a permanent fix - it's not economically viable.
