AS350B3 VERT FIN STRAKE?
Looking for some info on the difference between the long and short vertical fin strakes on the AS350B3? Aerodynamic differences between the two? And this is why..............
Recently had to have the tail chaged on a b3 due to bulging and cracking at the base of the left side of the vert fin Eurocopter said it was most likely due to improper riveting? The tail has been repaired multiple times withing the last year for the same problem. Mind you this is an EMS ship that really only flys straight and level.
Our vert fin was equipped with a full length strake, which i have never seen before on a b3. Could this have had some influence on the cracking and bulging of the metal on the fin?
We now have the short strake along with a new fin.
Thanks everyone!
