Engine Failure During my I-6 Checkride
Posted: Sat Jun 03, 2017 7:28 pm
Hello dear friends!
This is actually my very first post on PE Forums, I`ve joined the PE community only 2 days ago and please let me say; as a real-world Instrument Rating student in Part 141 flight school, I can`t describe well enough how helpful PE is when it comes to practicing real-world IFR procedures and flights. As some of you may know, as an IR student you don`t really get to fly under an IFR flight plan except for only a couple of flights during your training which sucks.. So what I`m trying to say is that, I`d like to thank PE Team for providing this excellent service, so people like myself can practice and sharpen their skills. You guys truly are amazing!
So, this evening I was doing my I-6 Checkride. I departed RWY25L at LAX on SLI7 departure procedure, climbed via SID, then up to 4000ft MSL. (check out the picture below) Just as I was being vectored to SLI by the DEPP, the C172S that I was flying started vibrating/shaking like crazy, and I looked at my RPM gauge just to realize I lost about 1500RPM. I had full mixture in, full throttle in, fuel selector was on BOTH, Shut-off valve was all the way in and key was on BOTH and I had about 4h worth of fuel. I was in VMC above an OVC layer of clouds and the OAT was about +20C.
I had no idea why I`d lost the engine and I was unable to maintain 4000 and forced to descend. I actually got really lucky because KLGB (long beach airport) was just North of me and I was within the gliding distance to it. After declaring emergency I was cleared for visual RWY30 approach into LGB. I made a safe landing and survived. I was expecting engine to stop spinning as I was rolling down the runway but instead it didn`t actually quit, and was running relatively smooth at 1000RPM at full throttle. I was basically getting 1000RPM at max power.
So, I have NO IDEA why I had lost about 1500RPM. It can`t be induction icing because I was in VMC and OAT was way above freezing. I don`t think I lost a mag, because I lost way too much RPM than a mag failure would cause. And I don`t think it was my error, because when I lost power, I immediately went thru the memory items for engine failure and everything was how they were supposed be.
However, I did install XPrealistic PRO prior to that flight and actaully crashed the same C172 into the ground because I was playing the XPrealisticPro`s settings. So my best guess is that XP11 keeps track of how pilot uses the plane and gives you random malfunctions if plane`s been damaged? Because the Tachh and Hobbs times seem to keep track of your flight hours. I did some research but I couldn`t find anything, so if anyone of you out there has an idea why I had lost 1500RPM during cruise I`d love to hear it. Like Does XP11 give you random failures? or was it XPRealisticPro?
Make sure to check the picture below which is a rough estimate of what my flight path looked like.
Thanks! And Fly Safe!
