Well the day started well, but I did end up in a field on the Isle of Sheppy after the engine stopped!
The weather suddenly turned for the better this afternoon and the forecast for the weekend was iffy to say the best, so I took the afternoon off work for a bit of fun. The flight started well with me doing some steep turns and playing around and above the clouds. I then dived from 3500′ to 900′ doing about the 100mph to skim the coast. This was where the engine decided it wanted to have some fun as well. Then at about 900′ just off the river bank, the engine lost power. I immediately applied full power, the engine picked up and then died! At this point I was doing about 90mph about 900′ above river and marshes… oops! I turned inland and slowed to 55 mph as this gives me the best distance for least amount of height loss, checked the fuel was on, checked I had enough fuel. I then aimed for a field that looked good, but not into wind as I thought I could make this one. I perhaps should admit here, that I have never glided Hotel Sierra as I always felt the engine likes to stop in the air at very low revs so this was my first ever glide approach! I tried re-starting the engine but no go. I was now down to about 600′ so put out a call to the airfield 15 miles away, but did not expect it to get through (and it didn’t). About 200′ off the ground I saw that the field I was going to would not do as it had a ditch down the middle, so I went for the next field across and landed almost into wind.

This field was VERY wet and had long grass! As I got out the water came over the top of my shoes. I checked the engine and could not see any problems, so I got in and after a short period the engine started and ran perfectly…. carb ice! Now I was fairly sure of the cause. I rang the airfield to let them know I was safe and where I was and that I was going to test the engine and then (hopefully) fly home. It was arranged that Roger and John in their Thruster would come and fly as a Shepherd in-case there were other problems.
About this time, the farmer turned up so I spoke to him about what had happened and what I was going to do. He advised that I was not to go further down the field as it was a lot WETTER! He had moved his sheep off a couple of days ago as it was so wet
.
I taxied to the top of the field where it was only 1″ of standing water and tested the engine for another 10 minutes and then did a full power short field take off. All was OK, all I had to do now was get back to the airfield which meant crossing water again. I took the shortest route at 2300′ so that if it went wrong again I would have more time to plan next time. No problems though so I did a straight in approach to Stoke and put Hotel Sierra to bed in the Hangar. She is very muddy and will need a good wash down this weekend!

A very muddy Rans!
For the aviators among you, here is a synopsis of what happened. The air was cold and moist. The water temps were nowhere near the green area. I did a long descent and the water temps dropped further. The carb heaters are powered by ‘hot’ water so they failed. Long descent, low revs…. carb ice! From 900′ I glided over 1 mile to a suitable field!
Edited to add: From discussions on the RansClan on the internet, it is quite likely that it was not carb ice, but fuel starvation! It is possible with low fuel and a long steep straight dive, to starve the engine of fuel due to the routing of the fuel pipes over the back of the wing root! Solution, do not do long STRAIGHT steep descents (when low on fuel), do a curved descent to at least keep the fuel level above the height of the wing root on one of the wings.
