Take care of dispenser.

Since the dispenser fires flares in the desert, it's important to check it for small rocks and sand from aircraft rotor wash.

If rocks and sand get into the payload module and foul up the firing contacts and the firing springs, the flares will not fire. And there's no onboard digital display in the pilot or copilot area to detect a misfired flare.

The M130 has a photosensor to determine if a flare is launched, but fails to ignite. If the photo-sensor lens is blocked by sand or dust, the dispenser may inadvertently fire up to two more flares.

To avoid misfires in the desert, make sure you clean your chaff/.are dispenser like the TM says and more often if necessary.
