: An error in the design of the SINCGARS CCA PN means that some units may have trouble trying to turn in the part for credit.
We ordered a circuit card assembly (CCA), NSN 5998-01-539-5371. We were trying to turn in the old card to the supply support activity (SSA) because it’s recoverable. The issue we’re having is the PN on the circuit card reads A3307047-1. In the TM, it reads as PN A3307046-1. Is there a reason the two PNs don’t match? This is costing our unit $413.00 in expected return credit each time the SSA won’t accept the part.
WO 1 T.T.
NSN 5998-01-539-5371, PN A3307046-1 is CCA – Flexible Rear Panel – RT. The CCA is installed in the RT-1523F and RT-1523G line replaceable units (LRUs) that are components of end item (COEI) for the Single Channel Ground and Airborne Radio System (SINCGARS) Family of Systems (see Table 1 below for affected systems).

Due to a design deficiency, the CCA marked with PN A3307047-1 is actually PN A3307046-1 for NSN 5998-01-539-5371; it was incorrectly marked during manufacture.
In response, on April 13, 2023, CECOM issued a Maintenance Informational Message (MIM), CECOM-MI-23-01009, for this marking issue to the Modification Management Information System (MMIS) in the AESIP Portal HERE.

This MIM acknowledges that CECOM recognizes the marking issue and that the CCA marked PN A3307047-1 is the PN A3307046-1 for NSN 5998-01-539-5371. This should ensure a smooth CCA turn-in process and proper credit.
The MIM has further details and POCs. Units should include a copy of the MIM as part of the turn-in process for this CCA to the SSA.
