An IPB for a specific aircraft is identified by which NAVAIR number?

The correct answer is associated with the specific NAVAIR number format used for aircraft publications. NAVAIR numbers generally follow a certain structure that identifies the type of publication and the specific aircraft it pertains to.

In this context, the NAVAIR number "01-85ADF-4" indicates an Initial Provisioning Baseline (IPB) document for a certain aircraft system. The prefix "01" denotes that the publication is for a military aircraft, while "85ADF" indicates specific model identification along with the type of document being referenced. The last section, "4," signifies the version or change number of that publication.

Understanding this format helps in clearly identifying and categorizing the IPBs, ensuring that personnel can accurately locate the necessary maintenance and support documentation for aircraft operations. The other choices do not conform to the specific identifiers needed for an IPB regarding their structure and intended use.
