    DYNON Maintenance / False CHT/EGT readings

    Thanx guys! Roger, I'll ask our most knowledgeable guy on the to system give u a call. It's a bummer that our regular Rotax guys couldn't end this, feel it's almost an Avionics specialty.
  2. Can anybody recommend/ furnish contact info for a solid DYNON LSA Tech anywhere near Des Moines IA? Recurring problem (for years) with sporadic false readings & alarms on club owned 2008 CTSL. Discussed at length here in forum 2015 & are sure it's some type of 'ground' issue but cannot fix it. It will need expertise beyond our capabilities, will ferry it a reasonable distance.

    Sporadic High EGT Readings

    It has been my experience (this has happened to most of our pilots over time) that it begins with random spikes into the yellow/red zone 'til the alarm finally triggers... hard to pin down a 'steady' temp, as when it happens it jumps around (including drops back to green). Want to thank all for ideas, we've been dealing with this for quite some time and recall there's been two sensor changes now with no joy. Most are comfortable it is false alarm & not an engine issue, but very uncomfortable to passengers (& pilot too) when a red light & buzzer goes off! All of your thoughts will be passed on, thx!

    Sporadic High EGT Readings

    Additionally, don't know if makes difference however have run Avgas exclusively (with 25 hr oil changes)

    Sporadic High EGT Readings

    Yes, weld & EGT alarm same side... have not checked jets, looking for recommendations to pass on to mechanic, thx!

    Sporadic High EGT Readings

    A vexing problem; Club 2008 CT (1,400 hrs) has on several past occasions gone into spurts where (right) EGT alarm has sporadically triggered. Sometimes just landing & restart has resolved, have recently replaced all sensors & was fine for about 30 hrs, but happened the other day again. Don't know if related, however about 100(+) hrs ago also developed a fine crack in right side exhaust manifold, resolved by certified weld. Just had 100hr & annual with no probs detected. Any ideas?
  7. You are fairly close to Lake Okoboji where I spend some summer time with family... can't tell from your website if you rent any light sport?
  8. Reference the Badlands, nearest paved with cross wind runways is Rapid City (does get windy out there). Wall Dug is closest, but only one runway, and Rapid would give access to rental car to visit the Badlands up close & personal. Be aware going into Rapid, there is an AFB only a few miles away with a similar layout. Also be aware of pretty active MOA's in the area, and recommend coming & going at pretty high altitude if flight following desired (effective radar coverage is pretty sparse at lower altitudes in that area). Beautiful country!

    Right High CHT Alarm Issues

    Thx aldowns, will do as suggested. Really seems with all other temps normal must be sensor problem, was little concerned ref the exhaust pipe break having some significance to problem. Ever hear of that happening?

    Right High CHT Alarm Issues

    Have had issues over the years with 'false alarms,' usually due to sensor problems (darn glass panels!). Curious if anybody experienced something similar to this. Our 2008 CT suffered a clean break (in-flight) of the right rear exhaust pipe in late Nov '14. Was repaired by certified weld. Lately had experienced a series of 'Right CHT High Temp' alarms on one occasion, stopped after maint ofcr checked and tightened sensor connections. Several flights later taken on 200 nm x-country, fine on outgoing, but on return flight noticed right CHT creeping into yellow zone early in flight. Reduced speed under 5000 rpm as precaution, but continued as oil temps in green (200 - 205 degrees), and right EGT was consistently 40 degrees cooler than left EGT. 40 nm out from base, as soon as I keyed mike to call approach the right CHT alarm triggered, continued intermittently for rest of flight but seemed to be especially when mike keyed. Eventually alarm triggered continuously in pattern, through landing, and even during idle taxiing to hangar. Plane has recently come out of annual (after the exhaust pipe break), everything checked OK. Does this appear to be clearly only sensor issue?

    Parts service for CT's

    I hope someone actually affiliated with Flight Design reads this blog. I'm a member in an active flying club that collectively owns a CTLS. With seven to ten members at any given time, our (only) plane gets a lot of use, and as several are receiving primary flight training it sometimes gets a little rough and things get broken. We have had our plane down three times over the last two years, for at least four weeks at a time, with the vast majority of that time spent waiting on parts to arrive from someplace in Europe! We have currently been down five weeks, with an expectation of three more, waiting on something as simple as a motor mount! The last incident involved over four weeks to get a wheel assembly. My point is, FD is allegedly a leader in the LSA market... they make a fine product and I love to fly their airplane. You would think that they would therefore expend some resources to support what must surely be a large portion of their market... by stocking an adequate line of parts for their aircraft here in the US.

    Pending Incident becomes a non Issue

    This I not the 1st time this has happened, our CTLS lost cap and receiver last year in the same way (posted on this blog with pic's by robthart 1 August 2012), This really should be addressed by FD!

    Fuel Filler Assembly Lost in Flight

    FD fedexed the replacement parts & advised local FBO was authorized for this type of repair, plane back up in less than a week.

    Fuel Filler Assembly Lost in Flight

    Based at Ankeny KIKV 'neighbor,' he was returning from Chicago area so fortunately had good quantity aboard. Landed with 3 gallons, no hint of problem enroute, only way of truly monitoring something like this would be the sight tubes (but how many of us really include that in our usual scan?).
  15. A member of our flying club ('08 CTLS) was returning from a cross-country, and on landing discovered that the entire pilot side fuel filler assembly had departed the wing in flight, and siphoned out most of his fuel. Note from the photo that the only thing holding this in place is epoxy... be cautious when refueling and insure the (heavy) nozzle is held and not allowed to lean against the assembly frame (the presumed cause)!
