Mmmm ....
.....
Design - Is there any correlation between airframe serial numbers that have (or we suspect) suffered tail rotor blade separation and the 6400 and 6800 kilo weight certification? ....
Problems perhaps have more to do with the accuracy and tenacity of the chaps doing the T/R Tracking and Balancing then anything else ????
With normal ops on this a/c being varied between 100 & 102% Nr depending on the ops requirement I would suggest the balancing of the major rotating components becomes paramount !!
