The Repack Cycle requirement in the US is 180 days.
As of October 2015:
Due to some technical changes in the rules about how containers and reserves are packed and maintained, we want our customers visiting from outside the USA to be aware of a potential problem.
If your gear is not approved with a US Certification (also known as TSO or Technical Standard Order) then to be acceptable in the USA it only needs to be maintained to the standards in use by your National Aero Club.
If your gear is approved with a US Certification (all American made gear and any European gear with a TSO) it has to meet US standards for maintenance and packing cycles. This means it must have a seal on the reserve, be packed within 180 days of use, and be packed by an FAA approved rigger.
While we do not have any way to check the status of your rigger, in practice your TSO’d gear will need to be packed 180 days and the reserve will need to be sealed with the rigger’s number or symbol on it.
We will be working with our Federal Aviation Administration to resolve this as soon as possible. Meanwhile, we apologize for the inconvenience.
