The MEDEVAC hoist bumper/spring assembly in both TM 1-1520-237-23&P (Jan 19) and TM 1-1520-280-23&P (Mar 20) has the incorrect obsolete part number, BL-12750-3.
That part number, BL-12750-3, is a shorter crushable bumper and was replaced by BL-15975-3 with the issuance of an Alert Service Bulletin (ASB) by the original equipment manufacturer (OEM).
PD MEDEVAC coordinated with DLA to ensure the correct part number, PN BL-15975-3, is associated with the existing NSN 5340-01-512-0408. Make a note that this change will be included in the next update to TM 1-1520-237-23&P and TM 1-1520-280-23&P.
