Your use of the word clearance is possibly ambiguous here. To be clear, Clarence, following the vertical guidance exactly will not collide with obstacles (i.e. it provides physical clearance), but it will not keep the aircraft a safe distance from obstacles (FAA required clearance).

Pretty short ground roll. Did he catch the 2nd wire?

I think you answered your own question. Although you may not have immediately diagnosed the problem, you probably would not have tried to depart with a rough-running engine. https://www.avweb.com/ownership/dealing-with-stuck-valves/...

The exact crash location isn't public yet (is it?), but news reports have it south of Hwy 388. It is probably about 2,000 feet short of cleared terrain on the airport property. Departing from the numbers, there would have been some chance of making it back, at least to an area free of trees and...

I was wondering if there are any external oil lines on that installation. Just so happens I have a set of manuals which includes that model. Didn't take very long looking at the powerplant drawing to find item #25 -- HOSE - Oil Cooler P/N 63901-43. Circled in red below. So, yup, it coulda been...

...which would seem to imply that the leak only started after engine start...?

Okay, I think it's just a matter of semantics then. Often, the phrase "impossible turn" means not only the 180-plus degree turn, but making it back to the runway as well. Soft...but not too tall. It's not all that helpful if you are gently brought to a stop by pine trees 75 feet AGL, then drop...

Forgot to include the image from that video. The area where I suspect the A/C landed is circled in blue in lower left corner of image.

I'm not convinced he would have made it back. This is a somewhat arguable due to uncertainty in GPS altitude vs true altitude however. I see that ADS-B Exchange shows the same data as FlightAware, so at least in this case I don't think the FlightAware data is mangled by automated processing...

The A/C flew in from Orlando earlier in the day, and was at Panama City for over six hours. I wonder if an oil change was done by the FBO? Or maybe a quick-drain plug got stuck open? Filter or drain plug not safety wired? What else could cause that?

I cannot find tower audio for this -- it would start around 20:05Z on 6/6/2022. Does anyone have a source for that?

Last four pings show ground speed 66-71kts, with METAR at KECP 190@10kts with A/C course 330 deg -- about a 6kt tailwind if my math is correct, so airspeed would have been 60-65kts. Please cross-check my math there... KECP 062126Z 21010KT 10SM SCT050 29/22 A2987 RMK AO1 T02940217 KECP 062053Z...

N160LL '79 Piper Arrow, I believe -- PA-28RT-201, Turbo, I think. 2 Fatalities. Flight track available on FlightAware. https://www.asias.faa.gov/apex/f?p=100:96:383105945184::::P96_ENTRY_DATE,P96_MAKE_NAME,P96_FATAL_FLG:07-JUN-22,PIPER Edit: Not turbo, T-tail...

Local sheriff says a/c was "Piper PA-28 Cherokee" https://www.news4jax.com/news/florida/2022/06/07/officials-2-killed-1-hurt-in-small-plane-crash-in-florida/

That post reminds me of a discovery I made about the microswitches used to sense landing gear position on the Piper Arrow. The switches are not unlike the ones pictured in the example above -- they are not sealed, and not waterproof. On the Arrow, they are exposed to weather with gear down, and...

Excellent point. All of the info required to determine MDA would not be available to the firmware. You could conceivably add a system setting for approach category to answer some of the questions, but then what about the altimeter setting? Is it going to ask you where you got that? At some point...

There's been a lot of discussion in several forums here of how vertical guidance provided by GPS navigators for LNAV+V approaches should not be used below MDA. So the perhaps obvious question is...why doesn't the GPS navigator limit vertical guidance to MDA? After the advisory GP hits MDA, it...

So, like I mentioned in the post, this came out of a discussion in the Aviation Mishap forum. And yes -- once below MDA it's all visual -- that's the whole point of the image, so show why that's the case. If you have the time, go back and read through the discussion linked above, it's a good one.

I don't know how to do that. You might have to save the KML file on a google drive and then somehow load into the app and make a link from there. Maybe someone with more GE know-how can say? At this point, you have to cut and paste the KML file into a text editor, save on a local computer and...

Gryder fancies "Probable Cause" as the 60 Minutes of aviation, and his idol is Morley Safer ... exposing (more often, inventing) the evil lurking behind every aviation accident.
