NATOPS1 Posted February 17, 2011 Share Posted February 17, 2011 All props..... all areas (blade, spinner Anti ice and Deice)? Or just one? Or just one reading? Quote Link to comment Share on other sites More sharing options...
Dan Wilson Posted March 2, 2011 Share Posted March 2, 2011 Check the brush block, it may be getting ready to light off (brush block fires really look cool in-flight). Quote Link to comment Share on other sites More sharing options...
victorp1 Posted March 3, 2011 Share Posted March 3, 2011 In the late 70s I had something similar but I just had low amps in flight. The glue for the blade electrical contact ring (P/N 525807) on my number two blade had failed and when the blade angle was in the flight range the ring did not contact the brushes. During normal ground operation amps checked good but if power was advanced above 8,000 in. lb. on the ground we could get the same indications.

Lkuest Posted March 7, 2011 Share Posted March 7, 2011 I've seen at least three cases where the Blade De-Ice checks good statically and at LSGI, but as soon as we upspeed the motor, the blade de-ice lost some amperage. Every case ended up causing us to change the propeller. I've also seen a dome leak make the spinner contacts too dirty to pass voltage, so without you telling us which De-Ice is low, and how many engines, it's hard to say. If it is both spinner and blade de-ice on all props, think bus problems, or De-Icer Timer. Quote Link to comment Share on other sites More sharing options...
