: A quick reminder was sent in on the proper hardware stack up at the tailrotor hydraulic actuator input lever and tailrotor control rod. A situation can present itself where a 2nd (extra) spacer/washer can be left on the tailrotor gearbox side of the input lever hardware stack up. Especially when the hydraulic actuator is changed and includes new hardware. The existing washer can very easily be mistaken for part of the control rod assembly. The first potential clue of the extra washer is the control tube/input lever nut and lock washer interface is a “little” off. The second hard clue is the pilot will notice his tailrotor pedals are “off” a little in normal conditions. [Submitted by PA]
Multi-Model: If you are adjusting the voltage on an older style DC voltage regulator, where the adjustment screw is located through a small hole in a metal cover, insulate the shank of your small screwdriver with heat shrink or electrical tape. Many a regulator has had the smoke let out of them by engaging the adjustment screw and touching the metal cover. Especially when sitting under the nose of a running 212 or 412. [Submitted by Rw]
