The Powerfly carabiner needs to be changed after 1,500 hours in flight. (500 hours for Parafly aluminium carabiners)
The carabiner must not be used and must be replaced if:
- the gate will not close or secure itself on its own
- there is evidence of damage (cracks, distortion etc) which indicates potential failures
- the carabiner has been overheated or overloaded
- the total flight time of 1,500 hours has been exceeded
