Thread: Trutrak recall on CTLS autopilot controllers

At about 100 hours in my CTLS the autopilot display began to show streaks and blank lines on it. At about 200 hours the display become unreadable even though the unit functioned normally. This condition is well known to Trutrak and they are offering repaired/replaced units. Call them to get a RMA and instructions.

When you disconnect the autopilot controller you will notice that it has three pitot air connections. I don't know for a fact but I assume that with these nylon tubes hanging loose all pitot functions would be inoperative. At any rate, I wanted to plug them to keep any dust or insects out of them. Note that the tubes are flared on the end.

I found at our Tru Value hardware store that there are a number of connections for tubing. The one that fit these flared 1/8 inch nylon pitot tubes is labeled on the package "1/8 IN MIP PLUG STK NO 52659B" manufactured by Danco Company, Concordville, PA 19331. The bar code is 37155 52659.

I put these on the flared tubing finger tight (so as not to possibly damage the flared end) and the altimeter, airspeed indicator and Dynon all function normally in flight while the autopilot controller is away being fixed at Trutrak.

Russ,

Mine did it. Sent it in, they repaired and sent right back. Quick response.

I have the same problem and mine was changed by Lockwood at 150 hrs, current one is beginning to deteriorate. I would like a real fix. knolde

AP repaired under warranty quickly and with no other problem [+ recalibration + software update]. And if I remember right, now the display is blue .

Same problem here. Had to replace mine too at about 130 hrs in my ctls. Now the new one is almost totally blank. Waiting to have the time to get to my mechanic and send it for the new (blue) controller. Lets see if this is the definitive.

My LS is at 150 hrs, and my display looks fine. Should I leave it alone?
There is one serial number between Angel's and mine.

Ken,

The new units have different displays that are supposed to be better. You can send yours to Tru-trak for a new display, or since you purchased your plane from us, we can swap it for you at Sebring Aviation when we get some more in stock.

The new type replacement displays are available only from [august-]octomber 2009. I think that the replacements made prior to this date has be done with the old type display [that means with probability the same problem].

Well guys...don't feel "pregnant"...it's not just airplanes that have a problem...the FedEx truck in my avatar has the same problem with the odometer/trip meter section of my speedometer....had to get it changed twice under warrenty...stuff happens. I think the LCD manufacturers collectively were having a problem.
