The AT-ASB Working Group will develop a standard that eliminates differences in service bulletins for avionics products from different supplieres. The standard will also provide for standardization of Buyer Furnished Equipment (BFE) and Supplier Furnished Equipment (SFE) service bulletins, regardless of the aircraft manufacturer the avionics product is used on. The result will be a definitive standard that addresses areas in the existing ATA standards (ATA 100, iSpec 2200, etc.), which will allow format variances on topics such as pricing, wording, etc. This standard will also end the divergence of SFE service bulletin standards from the aircraft manufacturers and drive a single standard for all.
