View Full Version : Carb ice scare ...

The weather was bright and sunny and warm, the air fairly calm - and not too hot for my 532 with the small radiators. I had been experiencing over- heat conditions on climbing out in the un-British summer weather of the previous few days, but this day was fine and I was enjoying the flying.

I arrived near the airfield, rather too high to join at the top of the downwind leg, so I made a low power descent to arrive at circuit height in the right place. All seemed normal until I opened the throttle. No noise. No thrust.

I was prepared to land in the field below, but realised that I could make the runway and land against the traffic flow downwind. The wind was very light, so it did not make a lot of difference which way I was facing, and no one else was in the circuit.

I was pleased to arrive in one piece, albeit with a dead engine. My first actual engine-out landing! THe 532 would not start again immediately, so I could not taxy back, but after I had huffed, puffed and blown my way to the hanger, hauling the gyro behind me, it started again normally.

With hindsight, I realise I had early warning of what was to come. The engine rpm was gradually falling-off "all by itself" in the cruise and I had to increase the throttle setting slightly. But I did not put two and two together. Instead I assumed it was down to slightly too slack throttle friction.

Do not believe anyone who tells you Rotax engines are pretty well proof against carb ice. My experience has taught me otherwise! :rolleyes:

I had a 462 2 banger that iced up all the time.
2 bangers WILL ice up in the wrong conditions.
Good to ere you pulled it off John, practice makes perfect ay.

Thanks Birdy.

My only previous experience of icing was after a lengthy taxy at low rpm. When I tried to prerotate the engine died. And once my inspector had to tug the aircraft in after it died on him while taxying. So I have got accustomed to revving the engine up before engaging the prerotator. Never had this in the air before, though.

I am thinking of investing in the carb heat kit to make sure it doesn;t happen again! Anyone got that?

Thanks John.

I hadn't seen that thread, but I have visited it now. :)

John,
Glad to read you made it down ok. How are my blades serving you? How are they performing compared to the old ones?

Hi Udi

The blades are fine. I like them. DWs are half the weight of the McCutcheons, so I doubt if they do much for my thrust line, but they certainly do the job well!
I get a consistently good spin up to about 200 rpm, and it doesn't take much to get to flying speed from there.

(I was very pleased I didn't trash them! I think "She Who Must Be Obeyed" would have called a halt to aviation if I done any damage this time!) :rolleyes:

Incidentally, I was impressed with the glide angle, which was far less steep that I had imagined it would be once everything went quiet, and I was struck by how much time there was to sort things out. My feeling is that the glide is shallower with the Dragon Wings. Just a feeling, though.

The McCs, on the other hand, seemed more generous with their cushioning effect on landing. Maybe because they have more inertia?
