Poor Maintenance Practices

I've found this while removing the right hand heat exchangers for cleaning. The clamp was"sitting" on top of the pneumatic duct.

It is posible that the ducts have been removed & reinstalled back with the top duct been normalised first, the lower duct then was reinstalled without the mechanic that done the installation aware of the contact.

All pneumatic, hydraulic, flight control cable must be inspected for interference with adjacent structures to eliminate unnecessary defect in the future. In the case above, due to vibration, crack can occur which will lead to pneumatic leakage and subsequent damage.
