Aviateca 901 Accident Report, 11 Years Later

Thu Sep 21, 2006 12:51 am

An interesting read for the Spanish speakers out there...

La Prensa Grafica in El Salvador has published a special report about the accident of Aviateca flight 901. This a/c, a B737-2H6, crashed near San Salvador on August 9, 1995, just before completing the second leg of its 'milk run' MIA-GUA-SAL-MGA-SJO.

http://www.laprensagrafica.com/especiales/2006/aviateca/default.asp

The voice recordings point out there was a lack of proper communication between the pilot and the tower, which might have led to the accident. Specifically, the tower advised the pilot to turn "left" in the understanding that he would take the south route; however, the pilot's "left" was actually to the north, thus he diverted from the intended course. When the "whoop whoop" warning sounded, he tried to gain altitude again, but it was too late by then...

The other black box containing the flight information was never found.

Here is some more info about the accident in English: http://aviation-safety.net/database/record.php?id=19950809-1&lang=en

I would be interested to know whether any of you remember this accident, and can add more information about it. Even though GU became part of Grupo Taca a short time later, the memory is still alive among the employees, especially the ones with more seniority. I had a supervisor at reservations, who remembered exactly what she was doing that night, and the conversation she had with a flight attendant before the f/a boarded this flight...

Also, how common are these errors in ATC-pilot communication? Particularly errors like in this case, where the exact location of the airplane was unclear to both the pilot and ATC.

Saludos,
Carmen

Maybe something similar (of course not the same) happened with AA 757 that crashed minutes before landing at CLO. Both pilots seemed to be lost and ATC never really knew where they were, because lack of radar, and trust what the pilots told him.

Pls, if I'm wrong, don't flame me..........

There is a link to an English version of the report on that site...

The retired FAA Inspector on the jumpseat, Bob Miranda, gave me my Dispatcher Oral/Practical back in 1979. Great guy, and missed terribly by all that knew him. There were over 300 people at his funeral....

You mean this one?

Seems in this case it was not really a misunderstanding of ATC's directions. But it's indeed similar in many aspects, including the end result...

An interesting note, SAL lacked a radar as well and only got one as a result of the GU accident.

Thanks for the link... I haven't finished reading the whole report yet (I'm posting this from work, and due to the slow connection I have to take some time at home to read it).

This is my first post after been a long time reader of this forum.

I remember something similar with a Sam 727 that crash near Medellin in 1992 or 93 I think, the pilots reported that they were over the Abejorral NDB Beacon, they were cleared to decent, but they were in another place and struck a mountain.
I was living in Colombia back then and I remember that accident like yesterday.

Well, in a way the ultimate example must be KLM/PanAm at Tenerife in 1977, where the exact location of the OTHER plane was unclear to pilot and tower...

I vivid remember this sad accident.

Even more sad the time took for the investigation.

Indeed, a terrible occurrence... That was the accident with the most fatalities ever, right?

Just curious, how long did it take?

A friend of mine, A CM pilot [former LR's one] told me that the first investigations [several ones are necessary before issue a finalo report] took more than 4 years.

Four years?! Whoa...

Then again, I can imagine it wouldn't be an easy task with one of the black boxes missing.
