Trislander SB 190
Xtypeman and others, thanks for educating me about this trislander service bulletin, I'm curious as to why the 3 remaining trilanders in service have obviously been signed off as fulfilling the requirements of the SB and are in service, but one hasn't, and has been withdrawn.
Anyone know why this should be ? Was it a much older airframe, higher cycles, more corrosion or another reason ?
