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
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.
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.
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.
This report is on the Crossair flight 3597 crash which happens at Zurich airport on 24th November 2001. Analysis of Crossair flight 3597 will be covered, which includes details such as facts of Crossair flight 3597 crash, and the three contributing factors involved in the air accident. The three contributing factors are mainly Crossair, pilot error and communications with air traffic controllers.
Inspection between each flight besides avoiding accidents, it also helps engineers to understand what problems that would be aroused by operation environment. Pre-flight inspection of Aloha 243 was only carried out before the first flight each day which is inadequate. Besides, all inspection records at each inspection should be kept; it records all the status of the parts and help engineers to understand how the aircraft structures would be affected after each operation.
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.
Malaysia Flight 370 was one of the biggest blunders in the history of the plane industry. It seemed that a huge Boeing 777 disappeared mysteriously in the blink of an
It was the afternoon of July 25, 2000. One hundred passengers, most of them German, boarded the Concorde Air France Flight 4590. This was a trip of a lifetime for many people, as Concorde was restricted to the wealthy class of people. The excitement in people was cut short by the unfortunate delay in flight, because of maintenance in one of its engines. The passengers boarded the plane a couple of hours after the scheduled time. Finally, it was cleared for taxi on runway 26-Right. The pilots lined the aircraft parallel to the runway. A tragic accident, however, was about to befall.
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...
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.
airplane, it was finally successful for so many people to see. “6 years...until the first military
Aircrafts undergo a variety of stresses, strains, vibrations, and detrimental environments. It is important to inspect the aircraft regularly in order to keep the aircraft operable, which inspections of the aircraft is a big part of proper maintenance. There are many types of inspection; the most common one is pre-flight inspection and post-flight inspection. Under the Canadian Aviation Regulations (CARs), a pre-flight inspection is mandatory for Pilot Proficiency Check. During a pre-flight inspection, the pilot should use the pre-flight checklist to perform an inspection on the exterior and interior of the aircraft. It is a chance for the pilot to check any defects on the aircraft that may cause a problem, and the readability of the radio signals.
