That's why, once I'd scanned all the engine gauges and inspected everything I could outside the plane visually, and all seemed normal I felt that returning to the airport was the best course of action.<br /><br />You can probably tell in the video that I turned crosswind sooner than usual; I vaguely remember that being a conscious decision. At the same time, I think it was also fueled by an internal voice guiding me back towards a safe airport landing as quick as possible... just in case it did turn out to be something more serious.Stevehttps://www.blogger.com/profile/11130510691724323456noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-19961393621280118942012-09-14T22:27:33.854-04:002012-09-14T22:27:33.854-04:00I was taught about the same and, generally speakin...I was taught about the same and, generally speaking, the run-up is the last thing I'd do before takeoff. We just had some extra time elapsed due to a variety of factors. Lots of traffic and the earlier precautionary landing, both which essentially resulted in more time at idle power on the ground.Stevehttps://www.blogger.com/profile/11130510691724323456noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-63641387734347108322012-09-14T19:34:00.011-04:002012-09-14T19:34:00.011-04:00Even in the icing-prone 150, carb heat should be o...Even in the icing-prone 150, carb heat should be off on taxi - you don't want the engine aspirating unfiltered air that close to the ground. Because of this, I was always taught to check the carb right before take off to ensure that no ice built during taxi. Of course, one of the two times I experienced carb icing in a 150 was at full power on climb-out.Chrishttps://www.blogger.com/profile/11846593737518887287noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-32854830481876033802012-09-14T19:28:34.254-04:002012-09-14T19:28:34.254-04:00Wow, that was an amazing sound!

The renter, certain that the engine was about to explode, put the aircraft in a soft field across the street from the airport, flipped it over, and totaled the airplane - all because of a flapping seat belt. I'm glad your tale ended better than that.Chrishttps://www.blogger.com/profile/11846593737518887287noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-50942120387930103182012-09-14T12:22:29.771-04:002012-09-14T12:22:29.771-04:00Seems like a very good hypothesis to me!Seems like a very good hypothesis to me!Stevehttps://www.blogger.com/profile/11130510691724323456noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-14676042040090955962012-09-14T12:21:58.536-04:002012-09-14T12:21:58.536-04:001) Yeah, normally I call sooner but due to the nea...1) Yeah, normally I call sooner but due to the nearly-constant traffic flow things were operating a tad differently that day.<br /><br />2) Nope, carb heat was off and mixture was either slightly leaned or full rich. It's hard to tell in the video, but there <i>was</i> a slight stumble when I went to full power - that's why I held at full power for a couple seconds before releasing the brakes. Restart was smooth, carb heat off. However, I'd been sitting for a minute or so. Perhaps that was enough time in the 90-degree heat for any ice to melt?Stevehttps://www.blogger.com/profile/11130510691724323456noreply@blogger.comtag:blogger.com,1999:blog-1417693701650847558.post-88031363712510685612012-09-14T12:20:29.133-04:002012-09-14T12:20:29.133-04:00Think the carb ice broke free and clogged the fuel...Think the carb ice broke free and clogged the fuel in? choking it of fuel rapidly causing the shutdown?.....

Or was it closed and full rich? Didn't seem to be any stumbling when you did the run up to full throttle and sat there for a second before releasing the brakes. Odd that it reached full throttle without choking or stumbling and then dies rather quickly.<br />How did it restart? Smooth without alternate air or stumble?<br /><br />I've never experienced carb ice, so just my uneducated questions here. Either way, good turnout and I'm glad it happened then and not shortly after rotation.Rob Schafferhttps://www.blogger.com/profile/16371407125942674737noreply@blogger.com
