If an aircraft type avionics ILSP has not been published, the level of repair authorized at the unit level shall be in accordance with what?

• A. CG - 22
• B. Applicable maintenance manual series
• C. ALC
• D. ILSP

Answer: (B)

When you don’t have the avionics ILSP published for an aircraft type, you rely on the standard maintenance documentation to know what can be repaired at the unit level. The applicable maintenance manual series lays out what repairs and procedures are authorized for unit-level work, along with required tests and limitations. In other words, it provides the official scope of work you’re allowed to perform at the unit level when there’s no ILSP guidance. This is preferable because ILSP would define repair boundaries for that aircraft type, but in its absence the maintenance manual series is the authoritative source for what you can and cannot do at the unit level. Other options don’t fit because they aren’t the standard reference used to determine authorized unit-level repairs in this scenario.
