technical problem in Cessna 172SP whilst flying to Teuge

Last weekend, I went flying with my lovely sister-in-law, Micheline Bodson. It was her first time in a small plane, so we selected to go flying a Sunday with nice sunny weather conditions. The plan was to fly to the Netherlands and have lunch at their airfield of Teuge. However, something happened on our flight to Teuge.

After take off in Genk Zwartberg, I flew north towards Eindhoven and climbing out towards flight level 55. After climbing out, I checked the engine settings and noticed an error I never encountered before


I was wondering what this could be, just an erratic reading or something else. Probably nothing to worry about as the motor was running smoothly. I continued my flight.

Ten minutes later, the situation seemed to worsen as I got the following reading

2 out of 4 EGT sensors causing troubles

2 out of 4 EGT sensors did not work, a big fat red cross appeared. On top, the sensor of the CHT did not work either.

Not sure what to think about. Crazy sensor readings, but the plane runs smoothly, which is the most important. So I continued my flight and kept my worries for myself and landed in Teuge without problems. Here’s a screenshot of how our flight was retrieved on Flightradar 24.

First things first, we discovered a VERY nice restaurant on the airfield, with even a sushi bar. Amazing and atypical from what I typically encounter. Micheline and myself ordered a light lunch and we enjoyed a nice time as you’ll see on the picture below whilst I was thinking about our technical problem aboard.

I called the President our Gank-Zwartberg club, Michel Notelaers, as well as with Kristof Goossens, my flight instructor to discuss the problems I encountered on our one hour flight.

The advise I got was to perform a run up at full power, it the engine was running smooth, he advised me to fly back to Genk Zwartberg. Apparently, it is only a sensor reading which is false.

excellent and cosy restaurant in Teuge, what a difference

I performed the run up tests , everything seemed normal. However, after take-off in Teuge back to Genk-Zwartberg, the same problem appeared again…whilst the engine still runs smoothly. We continued our 60 minutes flight and landed early afternoon In Genk Zwartberg.

I noticed the plane was booked by three other pilots, I decided to stay at the airfield in order to notify them as it was a Sunday afternoon and the maintenance was closed.

I was somewhat pissed to see that all three persons who booked the plane after me that same afternoon, did not show up at the airfield and canceled their flights. Bad habit, especially on a sunny Sunday afternoon. I hurried to be back in time in Genk-Zwartberg, there was no reason too.

Luckily for me, some nice planes passed that same afternoon in Genk-Zwartberg and I enjoyed watching them on the terrace of our clubhouse.

I informed the maintenance of our club and they decided to fix the problem prior to allow further flying on this plane.
