Summary
Entering service in 1952, the de Havilland Comet I, was the first commercial airliner equipped with jet engines and swept wings. British Overseas Airways Company (BOAC) operated the Comet I with service around Europe, Africa, and the Middle East. Regrettably, after only a year in service in 1953, BOAC suffered the first in-flight loss of a Comet I, along with all aboard. Shortly after takeoff from Calcutta, India, the aircraft broke up after encountering a thunderstorm killing all 43 on board (Withey, 1997). However, it was two events in 1954 would doom the Comet I. On January 10, 1954, BOAC Flight 781 takeoff from Rome bound for London broke up only 20 minutes after takeoff killing all on board (Withey, 1997). Flight 201 from Rome

Advantages. By examining the wreckage investigators, can use various techniques find evidence of what the cause of the breakup.
Disadvantages. The debris lay at the bottom of the Tyrrhenian Sea and will take months to recover. Possible loss of life in the recovery efforts. The possibility of missing a key piece of evidence is high.
Alternative Action 2: Use an existing aircraft to perform tests to determine a possible cause of the incidents.
Advantages. Having an entire aircraft that has been in service should display some of the same flaws the incident plane may have been subject too. The ability to compare elements of the wreckage to an intact example to see if any damage was a result of the breakup or the cause of the breakup. The ability to perform experiments to create a similar failure mode for different assemblies.
Disadvantages. Utilizing in operational aircraft to a failure point that may or may not be reparable after the fact would be extremely expensive. Testing of an entire airframe would require large and yet uninvited testing equipment and procedures. Could the results of any testing be trusted to represent the incident aircraft
According to “A Human Error Approach to Aviation Accident Analysis…”, both authors stated that HFACS was developed based off from the Swiss Cheese model to provide a tool to assist in the investigation process to identify the probable human cause (Wiegmann and Shappell, 2003). Moreover, the HFACS is broken down into four categories to identify the failure occur. In other words, leading up to adverse events the HFACS will identify the type error occur.
Following World War II and the jet engine technology that emerged largely toward its end, aerospace engineers knew well that the technology had great potential for use in the commercial aviation industry. The Comet was the first aircraft to utilize jet propulsion; however, its designers failed to consider the metallurgy of the aircraft’s materials under flight conditions or the consequences of their atypical window design. The aircraft was designed by Britain’s De Havilland Aircraft Company and entered service in May 1952. After a year of service, however, the design issues mentioned above resulted in the failure of several Comet aircraft. Extensive evaluations revealed that repeated pressurization stress on the aircraft’s main cabin had caused its structure to fail.
Millions of people around the world have been impacted by the blunder of Malaysia Flight 370, but what actually happened? A normal Boeing 777 aircraft does not just disappear every day, and Malaysia Flight 370 seemed to do just that. Many wonder how an ordinary Boeing 777 carrying 227 international passengers can go missing in a blink of an eye (“Malaysia Flight 370”). Some think it was a contretemps, yet some think it was an intricate terrorist attack. Malaysia Flight 370 made a huge impact on the plane industry, and affected millions of people throughout the United States.
In conclusion, many contribution factors led to the Crossair flight 3597 crash but is mainly triggered by Crossair’s incapability of assessment, pilot error and lastly the air traffic controller. Analysis of a flight crash is important so that we will know the causes, thus being able tackle it, making sure that there are no other flight crashes like Crossair flight 3597.

Including the Boeing 747 is important in comparing the safety records between the two main aircraft manufacturers because of its popularity. From Boeing’s website, the 747 fleet has flown more than 5.6 billion people–about 80% of the worlds population since its first flight in 1969. There are also 838 planes in service in the Boeing 747 family. In the past six years the 747, Boeing’s flagship plane has incurred six acciden...
According the National Transportation Safety Board (NTSB) Aircraft Accident Report, determines that the probable cause of the Flight 811 was sudden opening of the forward lower lobe cargo door in flight and subsequent explosive decompression, (NTSB,1989). In figure 1, depicted the damage of Flight 811 when it landed.
On the 25th of September 1999, Big Island Air Flight 58 Piper Chieftain, crashed on a slope of the Mauna Loa Volcano in Hawaii at approximately 5:30pm. All nine of the passengers on board and the pilot were killed in the crash. The impact sustained by the airplane and the fire that followed the impact completely destroyed the airplane. Big Island Air Flight 58 was operating under CFR Part 135 air taxi operations providing sight seeing tours to tourists and locals. The Piper Chieftain had departed from Keahole – Kona International Airport, Kona Hawaii (KOA) at around 4:22pm. The airport reported that there were visual meteorological conditions that existed prior to the planes departure. The pilot had filed a proper visual flight rules (VFR) flight plane prior to his departure. The investigation that followed performed by the National Transportation Safety Board (NTSB) had determined that instrument conditions existed in the area of the crash site.
On November 28, 2004 at about 10:00 a.m. mountain standard time, a Canadair (now Bombardier) CL-600-2A12 (Challenger 600), tail number N873G, crashed into the ground during takeoff at Montrose Regional Airport (MJT), Montrose, Colorado. The aircraft was registered to Hop-a-Jet, Inc., and operated by Air Castle Corporation doing business as Global Aviation. (Insert Here)The flight was operating under Part 135 Code of Federal Regulations. The captain filed the flight under an IFR Flight plan. Of the six passengers on board, three died from fatal injuries and the other three sustained major injuries. The aircraft was totaled due to the impact with the ground and a post-crash fire.
airplane, it was finally successful for so many people to see. “6 years...until the first military
Now we have planes that can fly and take photos. But until now, no plane has been better than the SR-71, also known as the Black Bird. Lockheed Martin was contracted by the United States to make planes for them. On May 1, 1960, a U-2 flown by the US officer Francis Gary Powers crashed in the USSR. This caused tension between the two countries.
After studying the Aloha aircraft accident in 1933, our group is interested in the investigation in Human performances factors in maintenance and inspection. We have divided the investigation into 5 aspects:
jet services started with the Comet 4 and the Boeing 707. In the mid 1960's all
When I stepped into the large neatly organized white polished plane, I never though something would go wrong. I woke up and found myself on an extremely hot bright sunny desert island filled with shiny soft bright green palm trees containing rough bright yellow hard felt juicy apples. The simple strong plane I was in earlier shattered into little pieces of broken glass and metal when crashing onto the wet slimy coffee colored sand and burning with red orange colored flames. After my realization to this heart throbbing incident I began to run pressing my eight inch footsteps into the wet squishy slimy light brown sand looking in every direction with my wide open eyes filled with confusion in search of other survivors. After finding four other survivors we began moving our small petite weak legs fifty inches from the painful incident. Reaching our destination which was a tiny space filled with dark shade blocking the extreme heat coming from the bright blue sky, I felt my eyelids slowly moving down my light colored hazel eyes and found myself in a dream. I was awakened the next day from a grumbling noise coming from my empty stomach.
As the development of aviation industry grows, more and more aircraft crashes occur. There are many reasons that lead to aircraft crashes, but one of them, is because of improper aircraft maintenance. Why is proper aircraft maintenance so important? Proper aircraft maintenance is critical in order to keep the aircraft can function properly, every aircraft part is in good condition and ensure the safety of pilots and passengers. Proper maintenance has many parts. The most common part is inspections, which pilots do them every day; the main part is overhaul and repair of an aircraft; and maintenance documentation is another important part of aircraft maintenance which improper maintenance documentation has caused many incidents.
