How do you calculate the "Time Between Overhaul" (TBO) for cargo hook equipment?

Time to OverhaulOnboard’s cargo hook equipment has some of the longest time between overhauls (TBO) in the industry. For optimal safety and performance, regular maintenance and adherence to the overhaul schedule are essential. The exact TBO requirements for your equipment can be found in the Continuing Maintenance Manual (CMM) or in the Instructions for Continued Airworthiness (ICA) manual that is applicable to the kit, and are based on hours of external load operations or years in service:

  • Hours of External Load Operations — Should be counted as time when (1) anything is attached to the primary cargo hook (whether or not a useful load is being transported) and (2) the aircraft is flying. If these conditions are not met, time does not need to be tracked.
  • Years in Service — Should be counted from the initial installation date when the cargo hook is new or newly overhauled, regardless of storage or inactivity periods. If initial installation date is unknown, then count from the date of manufacture as indicated on the cargo hook data plate or from the date of last overhaul as indicated on the overhaul sticker.

Please visit the documentation section of the Onboard Systems website to find manuals for your system.


What parts do I need to send in with my overhaul?

Shipping box

Onboard Systems operates a certified FAA Part 145 Repair Station to service, repair and overhaul all of the equipment we manufacture. To determine if your Onboard Systems equipment has a service requirement, you can check the Component Maintenance Manual (CMM) or the Instructions for Continued Airworthiness (ICA) manual for a list of specific parts in your cargo hook system that need to be overhauled.

For example, many Onboard Systems cargo hooks (such as the 528-023-XX and 528-010-XX) also have a service requirement for the attach bolt. If the hook you are sending in for overhaul has a service requirement for the attach bolt, you will either have to send the attach bolt in separately or buy a new attach bolt as part of the overhaul. Either way, this oversight will increase the time and cost to perform your overhaul.

To avoid this, you should refer to the Component Maintenance Manual (CMM) or the Instructions for Continued Airworthiness (ICA) manual to see if the attach bolt or other parts are listed on the Bill of Materials (BOM) page. If the attach bolt or other components are listed as having a service requirement, they must be included in your package.

In most cases, the safest and easiest thing to do is to always include the attach bolt. If it has a service requirement, it is included in the cost of the overhaul; if it doesn't, there is no additional charge, and it will be returned to you with your overhauled hook.

Keep in mind that non-Onboard Systems parts (such as OEM suspensions, harnesses, etc.) should never be sent to us for service, as we are only authorized to work on our own equipment.

For more information about sending your equipment in for overhaul, please refer to this article in our newsletter, The Hook, "How to Streamline the Overhaul Process for your Onboard Hook."
