UH-60L: NSN for Pintle Mount Stop

Dear Sergeant Blade,

My unit recently converted to UH-60L helicopters. We are prepping for aerial gunnery and have three aircraft with crashworthy external fuel system (CEFS) tanks installed. There is a reference to a pintle mount stop in the -10 TM; however, we have been unable to locate any other reference or NSN for it.

Can you shed some light on this?

Dear T. C.,

We sure can. As a refresher, the pintle mount stop limits the range of movement of a mounted machine gun on the gunner’s window pintle mount whenever the external stores support system (ESSS) wings and tanks are installed.

The pintle mount stop’s NSN is 5340-01-389-7688, PN XM-144, and units can order it from the supply system.

There's a caution in the TM that prohibits the use of the machine guns when the external tanks are installed on the inboard vertical pylon. They're not prohibited for units, like yours, that have the crashworthy external fuel system (CEFS) tanks mounted on the external vertical pylon mounts.

Click on the link below to view the full caution statement and additional parts information excerpted from TM 1-1520-237-10 (Jan 19):
Always review the operator’s manual prior to scheduled gunnery live-fire missions.
