Frequently asked questions

What is the purpose of this order?

The purpose of this order is to provide information and guidance to aviation safety engineers for reviewing service bulletins that incorporate drafting concepts in FAA advisory circular AC 20-176.

What changes were made in this revision?

This revision clarifies guidance for referring to other documents in an SB, removes previous limitations on the RC label, adds guidance on differences between AD actions and SBs, and clarifies guidance on later approved parts.

What does the 'Required for Compliance' (RC) label indicate?

The RC label indicates which steps in an SB must be completed for compliance with an AD, specifically those that have a direct effect on detecting, preventing, resolving, or eliminating the unsafe condition identified in an AD.

How should service bulletins reference other documents?

An SB should not duplicate procedures but should refer to other documents for tasks if the affected operators have those documents, and must specify revision levels and dates when using mandatory language.

What is the significance of 'later approved parts' language in service bulletins?

The 'later approved parts' language allows for the installation of FAA-approved parts after the release of the SB without requiring an AMOC approval, provided the parts comply with the applicable AD.
