    From: "graeme bird" <graeme@gdbmk.co.uk>
    Just in case anyone else has the same problem: twice on a hot day, after a no problems morning flight, on return my CS prop wouldn't come off fully fine or respond at all. Controller etc behaving as expected. The prop is about 6-8 years old and 325 hours and has been great previously. I just had to fly old school controlling RPM by throttle and pitch to keep below max rpm (speed about 80knts). After investigation of slip rings, wiring, switches etc, I concluded the most likely cause was the two connections between the slip ring and switch wiring (blue and yellow/green), these are under heat shrink and comprise individual nickel plated screw terminals. I found the body plating to have come off and rusty and the terminal screw to also be corroded and rusty. My plane is always in a hangar. If anyone knows how the circuit works I'd be interested to know (its in the manual); I thought I had it worked out but had assumed normally closed switches that open at the limit but it seems they are normally open closing at the limit which has me confused (an electronics engineer). Found slight signs of burn on one contact. I understand the hub/switch arrangement has been changed on the current design. Another point to note is that although I had painted the collars at blade route with 2 part aluminium primer (which had halted some surface corrosion) During this investigation I saw that I hadn't painted all the way round by the switches. this required some further surface treatment. It would be a bad day if the collar split. -------- Graeme Bird G-UMPY - Mono Classic/XS FFW 912S, Woodcomp SR3000/3W CS, trutrak Gemini 2 axis AP, PAW, PFLARM core, ads-b out, 8.33khz, mode S, FP-5, Aera500, SD on Nexus, Smart A3 350 hours &amp; 6 years on the Mono, 930 total g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=482033#482033

    I believe your timed major inspection requirement is due. I=92m sure it is a simple problem but the maintenance requirements of your prop manufacturer must be followed. Woodcomp does not put its maintenance interval on their website. However i nstructions came with the prop. Ref: Woodcomp SR series Operators Manual Hours of operation Place of work Carried out by 25 hours On the aircraft Auth orised mechanic 150 hours On the aircraft Autho rised mechanic 300 hours At Service centre Produce r or Service centre 450 hours On the aircraft Autho rised mechanic 600 hours At Service centre Produce r or Service centre 750 hours On the aircraft Autho rised mechanic 900 hours At Service centre Produce r or Service centre 1.050 hours On the aircraft Author ised mechanic 1.200 hours Plant of producer Producer WARNING A record of these periodical inspections of the propeller must be k ept in the log book. So I would recommend at 300 hours you pull the prop and fly it or send it t o your local service center per the manufacturers maintenance instructions. In the US this has become too much of a problem for Woodcomp owners due to down time and shipping costs. We have had three low time (less than 300 ho ur) Woodcomp props throw blades or the internal mechanism fail here in Nort h America on just the Pipestral Aircraft, even though the planes were alway s hangared and flown in blue skies. So proper service and inspection of th ese or any prop is essential.
