Mystery of Bonanza A35 N8743A

[Music] today on flywire we're going to review the accident involving an a35 which was found near curie elko nevada [Music] hi i'm scott purdue and today on flywire we're going to review the crash uh that was found at this crash which is found in the mountains basically southeast of elko nevada north east of kyrie but nevada but quite a ways actually this accident just reverberates with me for a couple of reasons the family lost their lives and i'm not going to speculate on the why it happened but i am going to offer an opinion on two things first the red flags that jump out at me and two the way the accident was treated i guess i've got a bit of a soapbox to stand on here and this accident is a perfect example of the problems we face in the general aviation community this crash in particular is a bit of a mystery as i'll relate what the facts are okay so anyway let's talk about the facts and what we know of the accident so far and then i'm going to talk about the likely cause and then the wrap up with protocol for some of you this may be controversial don't say i didn't warn you okay just after lunch on friday the 24th of april 2020 a family of three departed chandler arizona in their a35 bonanza headed for twin falls idaho it was a flight of 567 nautical miles and i ran the numbers it comes out to be about four hours of flight time had with no wind by the book it will also burn 44 gallons of gas no flight plan was filed and it is unclear that the pilot who the pilot talked with on his way north there's no apparent record of that at this point the adsb data on this flight is spotty perhaps it's due to the fact that most of the flight was done around 8000 msl in and around mountainous terrain most folks don't realize that most adsb signals are received and processed by ground stations some satellite coverage exists and the original plan was to be for the ads b to be monitored from space and i'm sure that cost and resources led to the installation of ground stations and the resultant limitation to line of sight reception over large areas of the u.s in particular the the mountainous area of the west the airplane departed chandler in phoenix and then a little bit west and then pretty much north over sky harbor the airport there main airport in phoenix and then proceeded northerly direct towards twin falls pretty much in a b line southwest of flagstaff the adsb drops out somewhere and and then starts again just before crossing the grand canyon until about st george and then it drops out completely here's a couple of quick issues flying over the grand canyon is a special operation and we can still do it in most places with restriction unfortunately it appears that this pilot did not do that he flew flew near the vfr tuck-up corridor in a northerly direction but not at ten thousand five hundred feet as directed you can do a ten five or twelve five north pound his gps altitude was around eight to nine thousand feet the whole time typically gps compared to a barrel altimeter is only around 300 foot air range not a whole lot more than that more or less it also appears that he clipped the corridor and flew through the toroweep flight-free zone which restricts flight below 14-5 continuing to the northwest the airplane's last adsp as i mentioned was recorded near the northeast of st george utah and then the crash site was found to further 200 miles to the northwest near curie nevada it was the nearest town one other observation is that the flight flew through the severe and uh gandy moa both of which started 100 feet agl and go up to really tall most importantly the they flew through the r6405 the ttr which also starts at 100 feet and goes to flight level 560. this is a problem i can attest to the fact that fighters are using those areas from top to bottom at speeds greater than 89 nautical miles a minute they're not looking for little airplanes the restricted airspace alone is a serious violation the mob penetrations in my opinion are just not prudent i count two to three serious airspace violations on the flight so far and we don't know anything about his trip over sky harbor in phoenix was that just beetle across the airport i don't know for me this is a red flag disregarding the airspace rules endanger his particular flight as well as the the the right of all the rest of us pilots to fly in or near that airspace ga isn't the only user of airspace you can't always go direct even though the gps will draw a magenta line wherever you tell it to apparently when the flight was overdue in twin falls an all night was issued it's an all night and all not as an alert notice and it's sent out to people along the projected or the predicted flight path and in this case the airplane was found pretty much near that flight path on the way to twin falls apparently a uh another airplane found it near near ish kiri nevada but it wasn't that close it was basically out in the desert the ntsb did not travel to the accident local law enforcement found the aircraft and the aircraft was recovered the aircraft and the people were recovered and then aircraft was stored and frankly there's a paucity of information on this accident for y'all and rio linda that means there's not much both in the adsb data and the information the ntsb collected for the preliminary report there's hardly anything here at all except the fact that it crashed about where it crashed and three people died i mentioned earlier that when i did the flight plan the required fuel is about 44 gallons the fuel on board is important to notice in a standard 835 is 34 gallons usable what adsb data we have reveals that the airplane averaged around 120 to 130 knots ground speed over the flight and that's not nearly fast enough for the airplane to make this trip non-stop but for some reason it didn't stop it is possible that the airplane had an optional 10 gallon fuel tank but it sounds probably like he'll run out of gas anyway a news report had a quote from someone unverified that said the airplane came down hard nose first i'm not sure what that means it really doesn't tell me anything because the nose is going to be first typically unless it's in pieces i think the ntsb probably assumed that the airplane ran out of gas and decided it didn't have the resources to spare they collected some data filled out the report moved on to other tasks the accident this action is one that has received little attention and is not likely to gather a garner much more at this point but many questions in my opinion are left unanswered meanwhile most pilots and i would hazard guess that most civilians are under the impression that the ntsb will figure it out and then they're going to give us the results in truth this happens rarely the number of accidents that marry merit a recommendation within ntsb are less than 10 percent of the total for the majority of final reports that i've seen the narrative is often written describing what happened that's it not the why not the trigger not the chain of the of events that put the accident together no usable data we as pilots can use to educate us to the pitfalls and problems that this pilot faced we're on our own for this i for one think that this is a disservice to the family and to the pilot community just why do we catalog these accidents anyway when a high profile accident happens the internet becomes ablaze with speculation as to the cause and the cure of each accident with all the blanks typically filled in by imagination not necessarily fact for some reason we humans are attracted to bad news i can't explain why i'm not going to try without data people will often fill in the blanks without any basis in fact just what they think this is a negative result it's bad and bad and even correct data has a longer half-life than truth and it keeps us further away from solving the problems that we all face so just what is the role of ntsb in accidents of this kind they you know i'll admit they really are strapped for resources there is a growing problem in that a lot of the investigators they have are not pilots or mechanics this leads to large gaps of experienced amongst those charged with telling the rest of us what went wrong and also it leads to fewer accident reports that came sorry at least a few accident reports that contain any analysis at all i honestly believe that most pilots are not fascinated by this stock car racing phenomena pilots don't want to see a crash they want to avoid being being in one but waiting for the government to file a report in a year or two or three without any real analysis leaves a lot to be desired the disconnect between the event and the report is a gulf that cannot be spanned it just isn't it's not happening the system is not working for us at all regulation will not solve these problems if the pilot maintenance and operator community understood what the problems are what the me the risk and the results of certain behavior is then i think they would coalesce and figure out a solution outside of the faa regulations outside of being regulated to do it more rules tend to backfire like 43 alpha blundering through restricted airspace so what do we do well the crash of 43 alpha is a perfect example of how not to investigate and how not to share the results lawyers in courts can hack out blame all they want the air force has a system where we figure out what went wrong and then over here they figure out who to blame it's not together they're not together meanwhile while all this is happening pilots and passengers keep dying in accidents that can be avoided the trouble is is we don't know the details that are important we have to infer and that's just not good enough the ntsb agents they do a pretty good job of recording the facts with limitations preserving the wreckage for the most part however when they don't travel to the scene of them to this accident scene the result is often a jumble of stuff that no longer retain enough of a story to use in the investigation when i went through action investigation training in the air force i learned that the smallest detail the seemingly least important piece of wreckage can tell a huge part of the story and more importantly without that detail you might not have enough information to determine what happened okay and then figure out how we can stop doing that again how we can stop future accidents the other thing i learned is that while you do put a theory together about the cause and the progression of the accident you take all information in an unbiased manner and apply it if the facts run counter to your theory you build a new theory that matches the facts that's kind of the science way to do things uh there this is where a lot of folks misunderstand how you figure out what happened and most importantly the why in an accident that can lead us to solutions to avoid further ones to collect meaningful data you need a protocol you need a system or a checklist that folks can use to recover the wreckage and preserve it in a manner that won't obscure what happened i know that the ntsb has trouble with the resources traveling to every accident there's quite a bit of them but as i said the ntsb does a pretty good job of this in person but when they rely on law enforcement or others a very per job is done and meaningful that is lost a case in point is the recent 182 crash that greider's been talking about lately then went to the scene and he found the engine throttle body at the accident just laying there on the ground next to the crater and the position of the throttle is very important to determine what was happening to the engine at the time of impact and that was very instructive about what the crew what the pilots and were doing prior to the crash that is how we figure stuff out i'm involved in the accident investigation of an event that occurred about almost not quite four years ago for this one the faa and the ntsb had representatives at the scene within hours of the accident i came into this investigation at a much later date and i needed to work backwards from the wreckage through the last five minutes of the flight or so to determine what happened okay because they didn't do that uh what was important to me is that i could not that i could not glean from adsd adsb data were things like the heading of the airplane as it lay on the ground the distance from the impact crater to the place where the fuselage lay okay i already knew the path of the flight the position of the throttle the propeller and the mixture controls it was an engine failure these things among others were critical to capture on the scene before the airplane was moved unfortunately they were not and this leads to inaccuracies in my determination or any investigator's determination of the final moments of the airborne flight path for that airplane in that accident i can infer it from other data but it is a serious loss and it is an inaccuracy in the case of this a35 there was nothing done to determine if there was fuel on board or in the carburetor no inventory of how the airplane was configured did it have that extra 10 gallon tank or any issues anything together with the impact of the airplane was it under control was it stalled all the kinds of oh there's all kinds of questions here that went unanswered i'm not saying that i have all the right answers that i know exactly what questions should be on the protocol for accident recovery but i do have some inputs and most important and one and the most important one in my opinion is that there should be a protocol that it disseminated far and wide because you never know where or when an airplane will come down preserving the data that crashed the wreckage so we can figure out what happened is paramount importance form a purposely collected data set for each accident that includes as much flight information of all types as possible perhaps in making a database interested parties can determine probable cause and lessons learned that will inform mitigation strategy strategies that will result in saving lives this is the ultimate goal save lives and prevent the slow erosion of flight for the average american i think and it'll also affect other people in the world i think that is the main goal here there aren't enough resources in the dot budget to fund enough educated ntsb agents with the relevant backgrounds to serve aviation the need that aviation has here and i think we need to crowd source solutions i think that's the only solution here then we need to collect the data and we need to be transparent with it okay too much secrecy and stuff is bad our present system is not working for the users of the system throwing more money and regulation is not the solution uh make the data available to interested parties in the aviation industry the crowd will find the solution and well frankly they have the most at stake here not the folks that work for the government anyway that's my soapbox and i told you that it might be controversial we have to stand up and be the adults in the room we have to take ownership of our mistakes and learn from others mistakes leave me a comment below i look forward to hearing from you the the more of us that say something the more likely we will have an impact we aren't saving the whales here let's save the airplane and we'll save a life too mysteries like what happened to 43 alpha to tom stacy and daniel kevin are not acceptable at least that's my opinion i hope you liked the video and if you did hit like and subscribe it looks a bit like this here uh if you'd like to support the channel like my patreon supporters
