I was fortunate to have a strong tailwind that assisted me in reaching the airport with a non-event landing. My mechanic said the engine failure problem was caused by lack of lubricating oil due to improper preheating. This engine had just 380 hours since overhaul. During engine rebuild my mechanic insisted that I install a preheating system and recommended the Tanis brand. I followed his recommendation and have been extremely pleased with the Tanis heater.
This failure happened to me back in the mid 1980s and I have installed Tanis heaters on each aircraft owned thereafter. I currently use the Tanis TAS 100 on my IO-360. I use this system from Fall to Spring, which is generally October to April. The Tanis heater is very economical to use, so I keep it plugged in 24/7. My electric bill cost to keep my engine properly heated in an unheated hangar is approximately just $12.60 month. I now have the piece of mind that my engine is properly heated and ready for operation.
I have over 20 years of experience with Tanis engine heaters and have had 100% reliability with your equipment. Furthermore, I have not experienced any problems associated with cold weather operation and I strongly recommend to all aircraft owners that they consider using your products.
