A DA Form 2028 change request has been approved for the Chinook F-model, TM 1-1520-271-23&P (Aug 18).

In WP 4796, the section on removing the mass memory server (MMS), a note will be added that says,

“If you are removing a MMS, NSN 7025-01-613-2079, P/N 903209-1, on an aircraft without 29 or 30, retain the dust cap on the J4 connector to put on the new MMS.”
