Thats a very dull report from RTHK......
Ive heard third hand,,
The company has found CCTV footage of ( a part ) or parts falling into the sea from the departing AW139 from Shun Tak.
& They are looking at the "elastic numeric bearing " area on the failed blade.
Only one blade is missing, broken near the attachment point.
& This week Macau AACM has issued an (immediate inspection notice) of the TR blades to the Company.
Anyone have a diagram or photo of the AW139 blade ....
