Accident Investigations

NTSB preliminary reports do not draw conclusions as the cause of a crash.  But the NTSB’s preliminary report of the Turbine Otter crash that killed 9 near Ketchikan on June 25 suggests a weather-related “CFIT” crash, exactly as described here.

First, the report indicates that the flight was conducted under Visual Flight Rules.  That means

Let’s get it out of the way: there is little in common between the apparent loss of AirAsia Flight QZ 8501 and the disappearance of Malaysia Airlines Flight MH 370.  

But Flight 8501’s disappearance does have at least some resemblance to the 2007 loss of Adam AirAirAsia A320 Flight 547.  Both Indonesian airliners disappeared shortly

Airport fire trucks must get to a burning plane within three minutes if they are going to save any lives. That’s the maximum response time allowed by the National Fire Protection Association, the organization that sets the standard for airport firefighters, including those working at U.S. Air Force bases.

But there is one wrinkle.  The transponder was reportedly turned off when air

This animation compares what Asiana 214’s approach should have looked like to what it did look like. From the data we have, the animation appears to be fairly accurate, except the audio is not properly synchronized. (The initial transmissions are from when the aircraft was 7 miles from the runway, not several hundred feet.)

As described here, passenger claims against Asiana Airlines are limited by the Montreal Convention.  But any claims the victims’ may have against a manufacturer of the aircraft or its component parts are not.  

NTSB Chairman Deborah Hersman reported that evacuation slides opened inside the passenger cabin. The slides are, of course, designed to
