I have passed this one even though it seems at first glance rather thin because, looking at what's out there, the article creators have used just about every source they could for an event 36 years in the past. It passes in the sense that it's almost as good as it's probably going to get and is regretfully too short to be a serious FA candidate.
I would improve it a bit by changing things like "Buffalo, NY" to "Buffalo, New York" per Wikipedia's style guidelines, and adding some other categories this might fall into (I found a couple that I'll do already). Daniel Case 13:32, 24 September 2006 (UTC)
There are a couple of issues in these external photo links.
First, there are 2 separate ones. The 'simplication' edit eliminated one, and I think both are important to get a good feel of the rising terrain (which is at the heart of this accident).
Second, this photo site has a peculiarity (probably intentional) that requires the user to click on the full image link (ads and all) to refresh the cache. Unless you first refresh your cache, you cannot see the clean image. My compromise solution for now is to alert the reader to this effect, which allows the reader to refresh the cache and have access to the clean image(s) for a few days (depending on the browser cache settings), after first clicking on the full image link. This may not be ideal, but it does allow the reader to enjoy the clean image. If someone can think of another way to achieve this goal, please advise.
Thanks,

. Any other link that looks different than that, or that links directly to the JPG will not load properly, because Airliners.Net will think that you are trying to do remote linking. Most websites are now preventing remote linking, by replacing the image with their logo or something else if it detects it is being loaded from another website. I removed one of the images because without the airplane above the runway, the view of the field elevation is better. If you want to reinstate it, be my guest, but please use the appropriate Airliners.Net URL. --

There's also an issue of ease of use - I personally haven't been able to get either of them to display the image on its own; I fear that they'll just confuse people who would otherwise miss out on the photo, even if it does have adverts etc. round it. As a kludge, there's always the risk that it'll be broken, and stop working. If we link using the correct technique, there's an implicit undertaking from Airliners.net that they'll keep it working. Once you're at the page itself, those who wish to open the image in a new window on its own can do so easily enough. Anyway, I'm sure if the photographer felt that having the photo embedded in a page destroyed it, they'd find some other way to display it. -- Scott Wilson 21:29, 15 October 2006 (UTC)
This article is named after the location of the crash rather than after the flight number. After doing some poking around, I found that this is probably LANSA Flight 502, service from Cuzco to Lima. Online, a scanned LANSA timetable from circa 1968 lists the Cuzco-Lima service as Flight 502 and a United States Senate press release from August 2006 refers to this crash as the crash of LANSA Flight 502.
Would it be prudent or necessary to rename this article? For the time being, I'll set up a redirect from LANSA Flight 502 to this article. plmoknijb 17:22, 10 May 2007 (UTC)
I will be doing the GA Reassessment on this article as part of the GA Sweeps project. H1nkles ( talk) 17:04, 17 June 2009 (UTC)
Links 1 and 5 in the references section are dead. I also put a citation needed template on the last section about the student who didn't go due to a lack of money. There should be a reference for that information. The website references also need more information. Per WP:CITE they should at least have the website publisher and accessdate. The author, date and work are nice to have if they are available.
Otherwise the article is fairly good, it covers the subject and the writing is sound. I made some minor copy edits. The images are good as well. I don't anticipate the article will require much work to address these concerns. I'll hold it for one week to make sure at least the last section is adequately referenced and the current references have good links and are formatted properly.

Not sure the aftermath section is particulaly notable (or referenced) and the mention of one non-notable student is not really required. It could have beens are not really encyclopedic and I would recommend that the section is removed. MilborneOne ( talk) 17:50, 17 June 2009 (UTC)

GA from 2006. Aside from the small amount of uncited material, this article is not broad enough. There is nothing in the investigation section and the article itself just looks smaller than it should be. Onegreatjoke ( talk) 01:21, 8 June 2023 (UTC)
The online copy of the Final Report is now cited in the article, and is currently in Spanish. I have not been able to find an official English translation, which would be very helpful. In the meanwhile, I am quoting below the OCR'd version of the "Causes" section of PDF document (apologies for poor formatting, feel free to improve):
Causas del Accidente.
La Comisión Investigadora, luego de precisar los hechos y efectuado el análisis correspondiente, estima que las causas que han podido originar el accidente del avión Electra OB-R-939 de la Compañía LANSA son las siguientes:
1. Causas originadas por falla de material:
Detención del motor N° 3 del avión, después del decollaje, que restó el 25% de la potencia requerida para realizar el vuelo obligando al piloto a regresar al Aeropuerto del Cuzco. La falla de este motor se ha producido por un mantenimiento inadecuado de la Compañía LANSA, al no haber tomado la acción correctiva apropiada ante las continuas fallas que venía presentando.
2. Causas originadas por inadecuada operación:
a. Acción operativa indebida al retractar el flap de ala después del decollaje, procedimiento en que había sido instruido el piloto, lo que impidió que el avión en la configuración en que se encontraba: tres motores operativos, peso bruto cerca al máximo autorizado y temperatura ambiente alta, adoptara un régimen de ascenso suficiente en relación con la gradiente del suelo, para alcanzar una altura sobre el terreno que permitiera la maniobra con seguridad para regresar de inmediato al Aeropuerto.
b. Decisión inadecuada del Piloto al regresar de inmediato al Aeropuerto con el flap de ala retractado y con la configuración y condiciones de avión anteriormente indicadas que hacen presumir que el piloto no debió virar para regresar, sino continuar hacia Oropesa para recién iniciar el retorno al Aeropuerto.
I might add google translate version of the above, but would not want to quote it in article space. Crum375 ( talk) 16:47, 8 June 2023 (UTC)
Causes of the Accident.
The Investigation Commission, after having clarified the facts and performed the corresponding analysis, considers that the causes that may have originated the accident of the Electra OB-R-939 aircraft of LANSA Company are the following:
1. Causes originated by material failure:
Stoppage of the aircraft's engine N° 3, after takeoff, which removed 25% of the power required to perform the flight, forcing the pilot to return to Cuzco Airport. The failure of this engine was caused by inadequate maintenance by the LANSA Company, as it did not take the appropriate corrective action in view of the continuous failures it had been presenting.
2. Causes originated by inadequate operation:
a. Improper operational action when retracting the wing flap after takeoff, a procedure in which the pilot had been instructed, which prevented the aircraft in the configuration it was in: three operative engines, gross weight close to the maximum authorized and high ambient temperature, from adopting a sufficient rate of climb in relation to the ground gradient, to reach a height above the ground that would allow the maneuver to safely return immediately to the Airport.
b. Inadequate decision of the Pilot to return immediately to the Airport with the wing flap retracted and with the aforementioned aircraft configuration and conditions, which lead to presume that the pilot should not have turned to return, but continue towards Oropesa to begin the return to the Airport.

This image was in the original article for several years, until removed without comment in 2013 by anon ip. I have now restored it, as I think it adds perspective, showing the general area and terrain where the accident sequence took place, from takeoff to crash. Crum375 ( talk) 10:33, 23 June 2023 (UTC)
The "Causes" section in the Final Report (in Spanish, see also an English Translation above) does not mention "overloading", so I have removed that term from the lead to conform to the Final Report. Crum375 ( talk) 20:45, 24 June 2023 (UTC)
