This pipe should be repaired
To go inside we need to open
some accesses
Repair should be done also here
(PPF1 area)

Repair status
TRT Wheel Repair and tests CommentsA1
A2 Done, OK Leak fixed
A3 Done, OK Leak fixed
A4 Done, failed Large, Repair is OK but leak in the other place
A5 Done, OK No leak before
A6 Done, partially failed Leak reduced but still large. Repair is OK but there is still leak in the other place
B1 Done, OK No leak before
B2 Done OK No leak before
B3 Done, failed Leak still at the level of 2.5 l/h (can be controlled)
B4 Done OK Leak was small, now no remarkable leak
B5 Done, failed Leak still at the level of 0.25 l/h (can be controlled)

Next steps:
•Today - try to go outside of the tube ( A4 and A6) and see what can be done at the place of connection.
•End of the week - Close C side (if no additional repair can be made) and start working with side A.
•When side A will be available to start preparatory work?
