Gulf Helicopters AW-139 Tail Rotor Fell Off
I believe there is a picture on heliops forum of the 139 registration A7GHA that was supposed to do a flight for Qatar Petroleum . After start and a Power Assurance check on ground the pilots noticed very heavy vibration so they shutdown and asked the pax to exit . The tail gear box fell of and a fire in the tail area ....( probably of hydraulic fluid origin ) was quickly put off by the ground crew . Some initial details suggest that one tail rotor blade probably came off first , which put the tail rotor out of balance which caused the TGB to shear off from the fin area and the fire that followed .This might have been what happened to the Hong Kong 139 too .
Any more info from the GHC guys or gals ??!!
