Pictures and Commentary

Nov. 29 - Sharp-eyed Sweepstakes Bonanza watchers at AOPA Expo in Fort Lauderdale, Florida, asked about whether their airplane had a heated propeller because they saw a short rubber leading edge that extended out from the hub on each propeller blade.

The answer is no, the propeller boots are not heating elements, they're part of the TKS "weeping wing" system installed by Aerospace Systems and Technology. The reason for the confusion is because the fluid delivery components for the propeller part of the system haven't been put in yet. Every other part of the TKS system has been installed - the reservoir, the pump, all the plumbing, the panel control unit, the ice light, and the wing and stabilizer titanium leading edges. But the McCauley propeller installed with the engine change came with a new-style spinner backing plate. This required a new slinger ring design.

Earlier this week, I got word that the new components should arrive from England later this week and should be ready for shipping next week. If all goes well, another piece of the year-long puzzle that is the Sweepstake Bonanza project will soon fall into place. Stay tuned next week for more updates.
