Painting of stressed monolithic parts
Recently “ Castellano”, the vendor who manufactured the “starflex paint”, has discontinued its production. A note has been added to the MTC 20-04-05-103 explaining that “self graniting paint M 118” has been replaced by RP 100, and “smooth paint M 119” has been replaced by RP 150.
The new paint RP 100 and RP 150 are manufactured by MONOPOL and can be ordered through “Interturbine Aviation Logistics” (Texas). The delivery time frame is approx 20 days.

Air Conditioning Control Box (P/N’s C215A1930101, 2, 3)
As the warm weather is here you may find yourself trouble shooting the Eurocopter Air Conditioning system installed in an EC120. We have found that a snag that sometimes causes this system not to work is a faulty Control Switch (item 1HU), located in the Cooling Control Box (item 25VB), found in the pedestal.
To do a quick function test of this Control Switch, remove and disconnect the Cooling Control Box from the pedestal and take it to the bench. Refer to the corresponding Control Box drawing found in the EC120 WDM Chapter 21-51-00-002. Using a digital multimeter selected to do a continuity check, attach the leads of the multimeter to pins 2 and 3 of the control box connector 208VC. With the switch in the “OFF” position there should not be any continuity. Place the Control Box switch in the “AC” position and your multimeter should now be showing continuity. If this is not the case to confirm that the switch is faulty remove wires 2151-39 and 2151-41 from pins 4 and 6 respectively of the switch, 1HU, using a standard plastic red/white extraction tool. With the two wires now removed from the switch, hold them together and your multimeter should now indicate zero resistance. If this is the case you have found the problem, the switch.
