Learjet 25
N345MC
6 people on board total
Last contact was at 61.8 miles south of MTY
Took off from ADN, bound for Toluca at 03:40AM local

Sad thing. The area is pretty difficult to acess and if memory serves me right it can be pretty remote. What about the Emergency Beacon?

It will be interesting to find out if this was a real Part 135 charter, lease, Part 91 or Part 134 1/2 trip. Condolences to the families.

The footage on TV makes it look at this was a very high speed impact, and given the distance from the takeoff point, this seems very strange indeed. The wreckage reminds me of the PSA Bae 146 crash.

I wasn't a fan of the lady's music but she was quite popular, it's always very sad when you see footage of people being interviewed a few minutes before something tragic, they state how happy they are and seem in good spirits, and then fate takes everything away so suddenly.

Saw this story. When I heard is was a Lear 25 first thing that came to my mind is a fairly old jet. Of course it could be flown safely but I feel like flying in a Jet that old can't be the best thing in the world for two reason that come to mind. One if it is part 135 its a smaller company that does not have newer planes, and maybe a company that is not making much money. 2nd someone wanted to have a private jet but did not have the money for a newer one. I feel like if you are going to fly around in a Lear 25 you might as well just fly first class commercial and charter when you need it or purchase a smaller cheaper jet or even turbo prop.

Hopefully this aircraft has a black box. I would imagine it will have a data recorder yes?
Always horrible to hear about any fatal incident.

Quoting questions (Reply 22):

Those are the different types of operations, and how they are classified in 14 CFR, or Chapter 14 of the U.S. Code of Federal Regulations.

Part 121 is scheduled air carrier, part 135 is a charter/commuter on demand air taxis, part 91 is private general aviation. It's just the way the different regulations are in U.S. federal law. This aircraft is not an airline so part 121 regulations do not apply. Part 121 is the only type of flying that has an age limit. So as long as the pilot can pass a medical he or she can continue to fly.

A steep dive usually doesn't generate those kinds of G's right away...it's pullup or bank that gets you. But Lears have coupled controls, right? The co-pilot should have been able to manhandle the controls enough to get the pilot off.

Quoting art (Reply 29):

Depends on the loading. Civil jets are rated to 2.5g at MTOW but they have (at least) a 50% safety margin, so they can reasonably be expected to reach 3.75g at MTOW. If they're below MTOW you get a lot of relief...you could easily pull 7g+ if the plane wasn't that heavily loaded.

Also, the restriction on his Commercial License that's "Not valid for carrying person or property for hire..". Isn't that the whole point of a commercial license? Why this restriction? Perhaps something to do with the VFR only endorsement.

I'm not so sure.

In the Payne Stewart accident and at least one other LJ accident, the probable cause was the crew forgot to turn on the bleed air.

In both of these accidents, the autopilot was engaged so the aircraft continued to fly for quite some distance.

Assuming the autopilot was not engaged or even inop, it's a possible cause.

There is a co pilot at the flight deck and if it ws really a heart attack, the co pilot should be able to react and at least call the ATC to report in with the situation, although according to wikipedia, the Learjet 25 is considered a pretty challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets. In addition, the workload of pilots are also considered pretty high as compared to more modern light jets.

As such, I am wondering if one or both of the pilots has any prior experience/lots of experience in flying LJ before......

It's been a long time since my CFIing days but I believe that's the restriction that's automatically granted when a foreign national with a foreign pilot certificate is granted an FAA "reciprocal" pilot certificate. It should also say something like "Valid only with Mexico pilot license # _______." It doesn't necessarily mean the certificate holder was ineligible to fly the airplane.

No, 2 are required. The early Lears can be a little bit of a handful, when designed, Bill's original intent was to only have 1 pilot flying when the 23 came out.

Given his age and the fact that he was VFR only, at night, maybe there was some sort of spatial disorientation involved? The 20 series are showing their age, if kept up they can do pretty well. So far this doesn't look like it's going to be an aircraft that was coming from a company that would be like that.

Yes the Lear has coupled controls. It's all cables in that thing. I've been in a situation where we had the trim go bad and it took every bit of muscle to hold the pitch until we got it trimmed back up with the secondary. A quick killer in the Lear can be runaway pitch trim if you aren't ahead of the game.

This accident kind of compares to one that killed one of the highest time Lear pilots in the world a few years back. http://www.ntsb.gov/aviationquery/br...ef.aspx?ev_id=20011220X02424&key=1

It is always boasted that the Lear has 7 spars in the wing and that it is over built. In actuality only 2 of the spars go from tip tank to tip tank. It is an airplane will get you into (and out of) trouble pretty quick.

FAA database check shows a valid commercial license with the same issue date, but the VFR only limitation applies to the HS-125, not the Lear. Also, it does not list the Private Pilot privileges limitation for the HS-125 as it appears is on that temp. I'm not sure why they would be different, because if it had changed there would be a new issue date.

If that were the case in this incident, would the two crew members be incapacitated after that short a time in the air reports stated that it was only 10 minutes after takeoff that the aircraft was lost on radar? I know that this is still in the preliminary stages and I am sure that the reason will be coming out in the future after the investigation is concluded.

I think you might had missed something, in front of the HS-125 Private Pilot Privileges VFR Only, there was a phase that read
LR-JET VFR Only;


I was referring to the FAA's online database, which is worded slightly different with no apparent VFR restriction for the Lear. Also, there is no mention of the Private Pilot Privileges only on the FAA database, which is why I found that odd since generally when those are changed, a new certificate is issued, but the online database shows the same issue date as the temp picture.

According to the above, initial investigation results show the plane descended abruptly from 35,000ft to 9,000ft before disappearing from radar. They are not sure wether the plane had or did not have a CVR or FDR. They are looking for the documentation regarding that.

Yes, but under ICAO Annex 13, the State of Registry of the aircraft gets to appoint an accredited representative if it would like. And foreign governments may ask for help if they want to. But the State of Occurrence has responsibility to conduct the investigation.

Have they released both pilots names yet? The last picture taken has 5 people in it. First reports said there were a total of 6 on the plane. If that is the case, then we would be able to question if there was only one pilot flying the plane.

However, updated reports say that there were a total of 7 onboard. 5 of the entourage, and 2 pilots.

Very sad! I suspect both pilots must have lost consciousness? Maybe a loss of cabin pressure? I can't imagine what else could cause such a plunge, without any distress calls if both pilots were aware of the situation.

Anyways, can anyone confirm how many were on the plane, and is there an official list?

Also, I have read that Starwood has some dirt on them, including one of the owners being busted for smuggling drugs on a few of the planes, and doing prison time for drugs. Could this perhaps be a sign of the drug cartel in Mexico being involved in this? Even Rivera had some issues with drugs in her past. The dirt on Starwood has me wondering how they could even be allowed to be in business anymore. Apparently they have several lawsuits against them too.

And before anyone takes a swing at me over the drug cartels.... Please.... Don't bite hard. Let's face it, these drug cartels in Mexico are doing some pretty awful things to people. Which is why I would not dismiss this as a possibility.

the Learjet 25 is considered a pretty challenging aircraft to fly in comparison with most general aviation aircraft and more modern light jets.

I would agree with that, and in all phases of flight. Most airplanes you can trim to fly hands off. I've never gotten a Lear to do that. Also, the autopilots in those airplanes absolutely suck. The best we ever got was altitude hold in level cruise. We had to hand fly up and down. It's moderately stable at lower altitudes but is a challenge up high.

Not to say it can't be done or taught, it's just a higher workload airplane than most. The adage is that if you can fly an old Lear, you can fly anything

Quoting brilondon (Reply 48):
If that were the case in this incident, would the two crew members be incapacitated after that short a time in the air reports stated that it was only 10 minutes after takeoff that the aircraft was lost on radar?

I can see the breakdown that would lead to this. The old Lears have a few idiosyncrasies that breed selective non-compliance. That selective non-compliance can get you killed when you have a system failure. System failures can also be pilot induced.

I'm not going to get into great details on the breakdown that can occur, but I'll say the old Lears require adherence to procedure to fly safely, every flight. That adherence to procedure is often lacking in shadier outfits.

When the FAA grants a "reciprocal license" it doesn't actually subject the applicant to an FAA checkride. They're basically saying that they're extending some privileges of an FAA commercial certificate to the foreign certificate holder because he has qualified in the foreign country, but since the FAA doesn't have direct oversight of the certification process of other countries, they put some restrictions on it.

Once I saw Lear-25 I thought two things. Either she owned an old lear because she wanted a private jet even though she could not really afford one or that she wanted or needed to fly private and could not afford a good operation.

I understand why should would want to and possibly need to fly private to get around smaller cities especially at 4am but if you can't afford a good operator with modern and/or well maintained planes stick with the airlines. At least that's my two cents to someone in this situation.

It seems like a very very high velocity impact from the pictures. Some type of mechanical failure won't be surprising.

The local (PHX) ABC station was reporting on this accident during their 11am news on Monday and had a story from ABC News. During the ABC clip they had a map showing the route the flight was to take.

I've seen more than one Lear guy hit 10K, accelerate to 306, get the overspeed and pull the breaker. That kills the cabin altitude warning also. If you do a bleeds off takeoff, forget to turn them back on, pull the overspeed, you won't pressurize. It's entirely possible that you won't even know anything is wrong (ears popping aren't going to be a good indicator going up) until you're passed out. The Lear climbs like a bat out of hell. Probably faster than you can recognize the onset of hypoxia if you've set yourself up for that scenario.

I would bet money that's what happened with Payne Stewart's airplane also. The difference there is the autopilot is actually worth a shit in a 35 as opposed to the 20 series. Those things are worthless above being used as an altitude and heading hold. I've never flown one that could be used in any greater capability than that. Handfly up and down, along with the approach.

Useful conciousness at FL280 is 2-3 minutes--since the clock started ticking on them at about 15,000 ft by the time they hit FL280 they would have been out. Age (one was old) and smoking (probably both?) decreases the time alot.

Also, the restriction on his Commercial License that's "Not valid for carrying person or property for hire..". Isn't that the whole point of a commercial license? Why this restriction? Perhaps something to do with the VFR only endorsement.

That looks like a normal FAA validation of a foreign licence, it would be enough for someone to use to get the type rating on and take it back to their original country of issue. In a private operation a pilot can fly a 747 and carry passengers on a PPL. They have have received a credit card licence in the mail later, the paper ones are normally issued at by the FSDO on the spot, the credit cards size can take a while to turn up. The temp certificate and and final almost always have differnt authorisations.

Many pilots with a foreign licence go through as similar validation process, and then use the type rating process to do a check ride to get a FAA CPL/ATP (after doing the writens). TSA have made this harder now.

The Payne Stewart a/p was most likely engaged in airspeed hold during the climb, that's why it porpoised up and down chasing airspeed all the way until it ran out of fuel. If you want to have a lot of fun try doing a coupled approach in a 20 series lol. Mr. Toad's wild ride!

Useful conciousness at FL280 is 2-3 minutes--since the clock started ticking on them at about 15,000 ft by the time they hit FL280 they would have been out. Age (one was old) and smoking (probably both?) decreases the time alot.

In the case of the famous Lear 25 hypoxia incident on youtube, the Captain(late 60's) held on just long enough due to the fact that he was a smoker. I don't see how that works but that came out in the investigation, the significantly younger FO was out like a light. Still it is a possibility given that time frame I guess. The sudden decent though tells me there was a better chance of pitch trim runaway or something else.

The plane arrived into Mexican territory on August the 31st. It was given to Ms. Rivera to use for free for the next six months as a "testing" period since she was interested in buying it. I´m not sure that is common practice but I find that strange. i´m not sure where they sourced the crew.

Just two days ago I've read on the Wikipedia about Alaska Airlines flight 261... the MD-83 there had a THS jackscrew failure, and poor maintenance practices were determined as the cause.

I'm, as so many others on this forum, really interested into how this has happened...

Extremely unlikely there is any similarity or common cause between these two accidents. The circumstances were completely different. Alaska 261 took place over more than an hour, for one thing, and that's just the nature of that kind of jackscrew failure. They had plenty of time to get on the radios and they were in control of their speeds all the way down.

This Lear seems to have reached 28,000 feet and then instantly dove straight into the ground at 600mph with no radio contact.

I'm not all that familiar with this plane but if others here say it's susceptible to mach tuck, that sounds like a plausible scenario to me, potentially combined with some other issue (like hypoxia).

I've seen a few similar arrangements with older Lears.

The planes really have no value for resale in the US as passenger carriers, and few folks would want to convert one for on-demand cargo charter operations.

Such an arrangement would require the prospective buyer to pay for fuel, ongoing maintenance, crew salaries, insurance, etc.

The only cost for the aircraft owner is that they get no income from the aircraft for the period of the test drive.

In one case I know, after a few weeks, the prospective buyer returned the plane, and the company scrapped it for parts in-house. In two other cases, the plane was eventually purchased for a couple hundred thousand dollars. Not much for 'private jet' but more than the company would have gotten selling the plane for scrap.
