Carb ice?

Carb ice?

They do do that.

Sounds like it, it was pretty humid in the area yesterday. Witnesses reported engine was running but at low RPM before it ran into the ground. Student was praticing touch and goes and on it's 3rd or 4th solo flight.

I was flying in almost identical conditions a few days ago (24C, dewpoint 14C) and got some carb ice. I'd been sitting at the hold short line waiting for traffic for a couple of minutes with the mixture leaned but no carb heat. At about 1500ft after takeoff from sealevel (full rich) the engine started going rough, it got a lot worse with carb heat, but cleared up after about 10 seconds of carb heat. No further problems for the rest of the flight, or the flight back.

In winter I usually leave the carb heat on during the entire runup and/or leave it on for 30 seconds before takeoff and also put carb heat on while holding short for traffic. In summer I guess I got complacent, but looking at the carb ice charts the conditions were in the 'moderate icing' range.

The 150 is just a very efficient fridge.

I tend not to use carb heat in the winter time if it is well below freezing. Moisture in the air is already frozen. Spring, summer, and fall type temps are when its use should be maximized.

Yes, definitely. However I live on the BC coast, so winter is pretty bad for carb icing.

It's been a while I flew something with a carb, so I'm looking forward to the comments of the experienced guys, but this is what I would do before take-off on summer days with the Grumman AA1:

Get on the rwy,
Step on the brakes,
Smoothly apply full power,
Carb Heat on for a couple of seconds,
Push-it back in,
Lean a bit,
Confirm I have my good static rpm,
Release the brakes,
Enjoy.

From doomsday news article:

She was surprised to learn the pilot is only 17 years old and that she was flying by herself.

How dare they allow her to fly solo at only 17.

[trampbike]

It obviously was the cause of the crash.

Another gem here...

And what are silencers for aircraft?

[photofly]

Whatever they are, the one they fitted was clearly a little too effective.

A three blade prop STC for the 152's.

Whats with the flower stickers all over the empennage?

Saw news coverage of the story this morning. She was clearly wearing an Air Cadet uniform. Sure looks like it could have ended much worse. Plane certainly looks totalled. Hope she recovers quickly and isn't scared from aviation!

Just goes to underline what several people have stated on here -- better to hit the ground under control right side up. Regardless of any other mistakes she may or may not have made, I'm glad she maintained control.

Yes, definitely. The nice thing about the 150 is that it's difficult to do any damage to either yourself or anyone on the ground if you have a mishap, as long as you're wearing a harness and you don't stall/spin it into the ground.

(This FR states two possible causes)

Carburator ice or flaps may have been involved.
People crying about age...

The plane was used for some sort of cystic fibrosis fundraiser a few years back or something.

Incident report came out: result is full flaps extended on T-O after touch and go (40 degrees) and it is not mechanical. It was the 3rd solo flight.

On a day when my head was not "in the game" I took off with full flaps. The aircraft "popped up" in what felt like a hundred feet. Airspeed was right at stall and never increased. My eyes started scanning and low and behold the flaps were still down-full. The plane flew, though slow. I retracted one notch at a time but I have to say I didn't wait until the electric flaps made it to the next stage before moving up yet again. So, in reality I likely went from 40 degree to 0 degree without any pause in between. Had to keep the nose down to keep building airspeed. I considered simply pulling back the power and land back on the runway, (after all I had about 3600 ft ahead of me), but I chose to keep flying. I'm sure many here will have their idea of what is best in that scenario and will share their thoughts.

This student was on her third solo. So, not many hours in the logbook. I am actually surprised this doesn't happen more often. I don't mean the accident itself, but take-offs during a touch and go with full flaps. Many schools don't allow students to do T&G's. Perhaps that has something to do with it, although many feel it's just a money grab. I don't buy the money argument. I'd like to think there is a safey aspect to the flight schools decision.

[CpnCrunch]

I think that's why they limited later 172s to 30 degrees of flaps. 40 degrees of flap is sometimes useful to have, but not quite idiot proof.

No.

At least she put the gear down.
