AMC1 31TGB.25(b) Factors of safety

ED Decision 2013/011/R

The dynamic loads on a balloon system are difficult to evaluate because metal or textile parts behave quite different.

In absence of a more suitable method or as replacement of a load test, the failure of the load bearing component shall be shown by the following method:

Multiply the limit load in the failing load path by two and distribute it as a static load among the remaining load paths.

For conventional designs, this is an appropriate method which is based on good service experience.
