This podcast series features discussions of critical and timely issues related to aviation safety and aviation security. Topics for discussion include fear of flying, major plane crashes, ongoing accident investigations, and air travel risk.
In this May 31, 2014 interview with Rudy Maxa's World, Dr. Todd Curtis of AirSafe.com discussed recent developments in the search for flight MH370, the Malaysia Airlines 777 that disappeared in early March 2014.
The Australian government, which is leading the effort to find the missing aircraft, had recently suspended the search and had announced that it would take about two months to conduct a thorough mapping of a section of the Indian Ocean seafloor before resuming the search.
On 20 March 2009, an Emirates A340 aircraft, with 275 passengers and crew on board, was involved in a tail strike accident during takeoff from Melbourne, Australia. The aircraft suffered some damage, but there were no injuries to anyone on board. The Australian Transport Safety Bureau (ATSB) recently released preliminary findings that indicated that an incorrect weight had been used when making performance calculations prior to departure. The calculations were based on a takeoff weight that was 100 tons below the actual takeoff weight of the aircraft.
This is the first accident involving an Emirates A340. Previously, in 2004, there was an Emirates A340 incident involving a runway overrun in Johannesburg, South Africa.
What sets this preliminary report apart from most is that the ATSB releases substantially more information at this stage than most accident investigation authorities. While the NTSB sometimes releases this level of preliminary information for major accidents that have tremendous media attention, it has not provided that kind of detail for other kinds of accidents.
This show features an interview with Keesin Ng, a passengers on a Qantas A330 aircraft that experienced a violent in-flight upset during a flight from Singapore to Perth on 7 October 2008. About 75 passengers and crew members were injured during this event, with 14 hospitalized with serious injuries such as fractures and lacerations.
The Australian Transport Safety Bureau, or ATSB, is currently investigating this event, and because of the extent of the injuries on board, the ATSB has classified it as an accident. In a media briefing three days after the accident, the ATSB reported that the Qantas A330-300 aircraft was in level flight at 37,000 feet when the pilots received messages from their aircraft's monitoring system indicating some kind of control system problem.
The aircraft reportedly had a uncommanded climb of about 200 feet, followed by a return back to 37,000 feet. About a minute after returning to cruising altitude, the aircraft abruptly pitched nose-down, to a maximum angle of about 8.4 degrees, and descended about 650 feet in about 20 seconds, before returning to the cruising level.
About 70 seconds later, there was a further nose-down pitch, to a maximum pitch angle of about 3.5 degrees, and the aircraft descended about 400 feet in about 16 seconds. During the first pitch-down event, a number of passengers and crew members were thrown about the cabin, resulting in a range of injuries.
The crew declared an emergency and diverted to Learmonth, landing about 40 minutes after the start of the event.
The interview occurred three days after the event with passenger Keesin Ng, who provides additional details about the in-flight drama. You can hear that interview at the link below: Interview with Keesin Ng (MP3)

A Qantas Airbus A330-300, with 303 passengers and 10 crew members on board, was on a scheduled international flight from Singapore to Perth. While in cruise, the aircraft reportedly experienced some type of sudden and unexpected altitude change. The crew issued a mayday call before diverting the aircraft to the airport at Learmonth, near the town of Exmouth, about 1100 kilometers or 680 miles north of its intended destination of Perth.
About 36 passengers and crew members were injured, with over a dozen severe injuries. Reportedly, several occupants were slammed into the ceiling during the event. Most of the injuries were to passengers and crew in the rear of the aircraft, and at least one person was carried off the plane in a stretcher. About 13 of the most seriously injured were flown to Perth by four aircraft from the Royal Flying Doctor Service. One flight attendant was hospitalized with suspected head and spinal injuries. Other serious injuries included fractures, lacerations, and a concussion.
The Australian Transport Safety Bureau has a team of seven investigators currently working on this incident, and it will likely be several days before a preliminary cause is announced, and several months before a final report is issued.
This is the first significant passenger safety event for the A330. Qantas currently has 15 A330 aircraft in its fleet, including 10 of the A330-300 model.
This is the second significant safety event for Qantas this year. On July 25, an exploding oxygen bottle blew a hole in the fuselage of a Qantas 747 en route from Hong Kong to Melbourne, causing a rapid decompression and forcing an emergency landing in Manila. No passengers were injured in that event.
Other significant safety events for Qantas in the last decade include a 2000 event in Rome involving the collapse of a 747 landing gear, and in 1999 a landing overrun in Bangkok severely damaged another Qantas 747.
In August 2008, the Civil Aviation Safety Authority of Australia conducted a review of Qantas safety and found no system-wide safety issues, but did recommend an audit of the airline's maintenance practices, including a full maintenance audit of one aircraft from three of the models flown by Qantas, the 737-400, 747-400, and 767-300. No maintenance audit was ordered for the airline's A330 fleet.
Additional information about this event, including updates or findings from the investigation or from the Qantas maintenance audit, will be available at qantas.airsafe.org.
