Are You Flying with the Right Radio?

Pilots, having the right radio in your Lakota rotorcraft is the difference between communicating and not communicating.

The bad news is that some RT-5000 radios meant for Kiowa OH-58A/C models have been installed on the Lakota UH-72A models. The wrong radio sets were moved into unit avionic stocks and used in Lakotas as line replaceable units (LRUs).

 

Both airframes use RT-5000, remote-mount, multi-band AM/FM transceiver radios. The version used for OH-58A/C Kiowas does not allow for digital transmission and reception of the same frequency signals like the RT-5000 approved for the Lakota.

If your UH-72A’s radio isn’t operating properly, eyeball the part number (PN) and cross check that PN against the proper supplemental type certificate (STC) for the correct Mission Equipment Package (MEP) of the rotorcraft.

Lakotas operating in a security and support (S&S) MEP, need the RT-5000s with PN 400-105525-6011 for comm #4, and PN 400-105525-6111 for comm #5. For Lakotas in a non-S&S MEP configuration, the RT-5000 radio should be PN 400-015525-5111 operating in comm #4.

If you find an unauthorized radio in your Lakota, make the following entry in the aircraft logbook:

 

“RT-5000 (PN 400-015525-xxxx*) required removal and replacement per aircraft’s STC with correct RT-5000 (PN 400-015525-xxxx*)”

*Ensure the PN(s) reflect the RT-5000 to be removed and the correct PN(s) for the MEP version that is going to be installed.
