All Drallim Aerospace Cargo Hook systems are designed and built to provide a long life and will serve Helicopter operators for many years providing the recommended Service & Overhaul regime is observed.
How often should I service my Cargo Hook?
What about cargo hook overhauls?
A full overhaul of the hook is required after 1,500 hours of external load operations, or 5 years (normal duty) whichever occurs first, or after 750 Hours of external load operations or 2.5 Years (severe duty) whichever occurs sooner.
Who Can Service My Cargo Hook?
The Servicing of cargo hooks and associated ancillary parts can be serviced by Drallim aerospace at our international service centre or can be undertaken by any EASA 145 approved Organisation authorised by Drallim Aerospace. But overhaul, due to its extensive non-destructive testing and replacement of critical parts, should only be carried out at our international service centre.
