  1. @Tim Jodice output of the main metering pumps and calibration of the proportioning units is based on panel design (older steel or riveted panels as compared to newer titanium and laser welded panels), line length for the installation and panel length. Nothing to do with fluid quantity.
  2. The no-hazard system and FIKI system for both Mooney and Bonanza are completely different. The FIKI systems use different porous panels, dual windshield pumps, dual solenoid valves, dual metering pumps (different output than the no-hazard system), different wiring bundles, added heated stall warning, different control panel, dual alternator requirement, different prop slinger ring (depending on engine and prop), different proportioning units (different output to the panels).
  3. Another reason there are more Mooney's with TKS... Mooney FIKI STC was issued 4/21/1995, Bonanza FIKI STC issued 3/14/2003. During that 8 year period Mooney's had TKS kits installed at the factory as well as retrofit. Bonanza's are all retrofit.
  4. Total M20K's with TKS = 102 89 no-hazard systems and 13 FIKI.
  5. @carusoam The no-hazard system has no requirement for dual alternators. The FIKI system does only for flight into known icing conditions. If the flight is not into known icing (dry warm VFR day) the dual alternator requirement does not apply. See page 8 of the flight manual supplement 08100-FMS: "9. The following equipment must be installed and operational for flight in icing conditions:"
  6. @apenney the sealant is stable and flexible from -76°F to 356°F. My guess is it never got put on during install if the stub is clean.
  7. @apenney Per our installation manual two sections of convoluted tubing are used in two separate places. You could measure your existing length of tube and purchase a new (longer) length of tubing to relieve the tension on the door. Additionally there is a NOTE in the install instructions "When connecting the convoluted tube, apply sealant to the pipe stub/inside of tube before assembly".
  8. @apenney clean the inside of the convoluted tubing and filler door connection very well with isopropyl alcohol and let dry. Coat filler door with a layer of Dow Corning RTV Sealant 732 (color of your choice), install convoluted tubing, tighten hose clamp and allow to cure.
  9. @FlyphillyPM me with your email address and I will send you a sealant cross reference list and installation procedures for the stall strip.
  10. AS&T changed names to CAV, so we are the same company. Original release for the FIKI was early 1995. Late 1995 updated the tail bracket assembly, 1996 we changed rivet specifications, 1999 added control panel option, 2004 added a two-blade propeller option and other minor adds through 2009. Admendments were added to the original STC for all these.
  11. @carusoam we write the Flight Manual Supplements for our FIKI (08100-FMS) and no-hazard systems (04600FMS). Not sure where the +30°C came from. The temperature in our FIKI FMS is a NOTE on page 21 Section 4 Normal Procedures which states: "Conditions exist for icing when the indicated outside air temperature is +3°C or below and visible moisture in any form is present."
  12. I would recommend TKS fluid with a lint free cloth as it can get into the porous membrane and tends to pull fluid to the surface. I've had success wiping the leading edge while running the system to pull fluid out of dead spots. If all else fails, we do have a purge procedure that isolates individual panels. If solvent has damaged the porous membrane you will know it. Fluid will typically squirt out of the panel 3-6 inches like a shower from the solvent damaged area.
  13. 6. Only the following solvents are authorized for cleaning the leading edge panels: Water (with soap/detergent) Approved De-Icing Fluid (see 3.) -TKS 80 -AL-5 (DTD 406B) -TKS R328 Aviation Gasoline Isopropyl Alcohol Ethyl Alcohol Industrial Methylated Spirit
