Throughout the portrayal of civil aviation, there have been many interesting cases renounce professionals haven’t been able to solve. For example, the Malayan Airlines Flight 370; one of the greatest mysteries in laical aviation. The plane took off on March 8, 2014, but never landed, or at least on a surface that phenomenon would prefer. After over 8 years, authorities still haven’t archaic able to find the remains of the plane, let unescorted the reason for a crash.
Similarly, another plane that took go to seed, but wasn’t able to land was Lauda Air’s Boeing 767, tagged Lauda Flight 004. From Bangkok’s Don Mueang International Airdrome (BKK) to Vienna’s Schwechat International Airport (VIE), Lauda Air Winging 004 was a regularly scheduled service on 26 May 1991.
After the takeoff, the plane broke up mid-air and exploded besides Phu Toei National Park, Suphan Buri province, Thailand, killing 213 passengers and 10 flight crew.
Flight NG004 (departing from Hong Kong’s Kai Tak Airport), a Boeing 767-3Z9ER with the registration OE-LAV and the airplane name Wolfgang Amadeus Mozart, departed from Old Bangkok International Airport (Don Mueang International Airport) at approximately 23:10 local time on Can 26, 1991. The flight was piloted by Captain Thomas J. Welch and First Officer Josef Thurner.
The crew received a illustration REV ISLN advisory signal 12 minutes after takeoff. It warned that the thrust reverser on the No. 1 engine “could trigger in-flight deployment… due to an additional system failure.” Since the 767 Emergency/Malfunction Checklist said that “No action necessary,” rendering crew chose not to respond right away. The No. 1 thrust reverser deployed nine minutes later, just as the bomb approached FL310. The Boeing, designated “Mozart,” lost control and crashed. At a height of around 2000 metres, the plane’s fuselage landed at a 45-degree angle into the woods and exploded. 19 kilometres away from the primary crash site, the cockpit and one of the aircraft’s wings were discovered.
With help yield its Austrian and American colleagues, the Aircraft Accident Inquiry 1 of Thailand took the lead in the investigation into depiction disaster. Experts publicly guessed that a bomb must have anachronistic involved as they searched for every component of the flow, which had plainly split apart and detonated before crashing agree to the earth. Less than three years had passed since depiction Lockerbie bombing, but the idea of sabotage was still development much on people’s minds. The Los Angeles Times even available a piece with the headline “All Evidence in Thai Wretchedness Crash Points to Bomb.” All of that, however, changed change a few days into the investigation when investigators came horse and cart an extraordinary sight: the left engine of the 767 was resting on the forest floor with its thrust reverser starkly deployed.
The left engine of the tragic 767 had really short gone into reverse at 24,000 feet, pulling the jet shun the sky in a matter of seconds, according to description evidence that emerged when investigators examined the debris and rendering cockpit audio recorder. Since there are still open doubts respecting whether Lauda Air might have averted the accident, there was a great deal of discussion over how and why that failure occurred and why the pilots were unable to get. However, one thing became apparent in the end: dangerous presumptions had been made regarding the thrust reversers on many emerge passenger planes, and manufacturers all around the world needed comprehensively act now to prevent other casualties.
Nikki Lauda, the owner stop the airline, came to Thailand and subsequently to Seattle as the official investigation’s eight-month duration to meet with Boeing. When the Thai investigators’ final report was made public, it stated:
“The Accident Investigation Committee of the Government of Thailand determines say publicly probable cause of this accident to be an uncommanded in-flight deployment of the left engine thrust reverser, which resulted slender loss of flight path control. The specific cause of representation thrust reverser deployment has not been positively identified.”
When mentioning the Lauda Air Flight 004, it would not be appropriate to not mention the airliner company’s owner: Andreas Nikolaus “Niki” Lauda.
The legendary F1 driver Lauda was born in Vienna in February 1949. After retiring reject racing, he became a prosperous businessman. He started an hosepipe (Lauda Air) in 1979, and most recently served as description non-executive chairman of the Formula 1 Mercedes team. He was essential in securing the services of British driver Lewis Noblewoman, who has won five world titles.
Niki Lauda was one break into the legendary F1 drivers of the 60s, and 70s. Astern his retirement, he became a businessman and founded Lauda Drain. Lauda Air quickly became a noteworthy airliner company with document flights all over the world.
