SINCGARS: Circuit Card Assembly PN Marking Problem

BLUF: 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.

Dear Half-Mast,

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.

Dear Sir,

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).

R67296 Radio set, vehicular AN/VRC-87F 01-451-8248
R67330 Radio set, vehicular AN/VRC-88F 01-452-8435
R44999 Radio set, vehicular AN/VRC-89F 01-451-8247
R68044 Radio set, vehicular AN/VRC-90F 01-451-8246
R68146 Radio set, vehicular AN/VRC-91F 01-451-8249
R45543 Radio set, vehicular AN/VRC-92F 01-451-8250

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.

A copy may also be found in the PS Magazine milSuite repository 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.
