Thanks to this valuable phorum we have recieved responses from other people:¨¨
Here is my cracked TR blade which I detected after Helisport had overhauled the Main and Tail rotor gearbox’s. (My pinion gear had failed at 400hrs, so Helisport insisted I post both gearbox’s to them for inspection and overhaul)
I had also experienced some corrosion between the blade and blade grip in 2004 and advised helisport to use anti-corrosion treatment in future blades. As far as I know this is still not being done!
A major problem with Helisport is they do not have a service & maintenance manual with technical information with correct procedures for servicing and maintaining the Kompress. Only when repeated problems occur, do they issue a service bulletin.
By not issuing such proper maintenance manual, this has frustrated many Kompress owners not staying near to factory.
Attached are the photos of my TR corrosion (which I had cleaned & treated with anticorrosion paint) and the cracked blade as I had received it back from Italy and noticed when I was doing at TR balance check after reassembly.
There are other German pilots who experienced severe TR blade cracking in 2007.
