Turbulence incidents, reports, discussion master thread

DEFINITION: Aircraft turbulence (American Meteorological Society)

Irregular motion of an aircraft in flight, especially when characterized by rapid up-and-down motion, caused by a rapid variation of atmospheric wind velocities.

This can occur in cloudy areas (particularly towering cumulus and lenticular clouds) and in clear air. Turbulence is the leading cause of nonfatal passenger and flight attendant injuries. The U.S. Federal Aviation Administration (FAA) classifies aircraft turbulence as follows:

Light: Causes slight, erratic changes in altitude and/or attitude, and rhythmic bumpiness as occupants feel a slight strain against seat belts.

Moderate: Similar to light, but of greater intensity, with rapid bumps or jolts, and occupants feel a slight strain against seat belts.

Severe: Turbulence that causes large, abrupt changes in altitude and attitude, and large variations in airspeed, with the aircraft temporarily out of control. Occupants are forced violently against their seat belts and objects are tossed about, with food service and walking impossible.

Extreme: The aircraft is tossed about so violently that it is practically impossible to control, and structural damage may occur.


Incident:.AA 280 ICN - DFW on December 16 2014 local time, operated by a Boeing 777-223ER and carrying 240 passengers and 15 crew, was subjected to a prolonged period of moderate turbulence and two minute-long sessions of severe turbulence near Japan. The aircraft diverted to NRT, where four passengers and one crew member were taken to hospital for evaluation and treatment; no serious injuries were reported.

The other passengers were bussed to a local hotel, and another aircraft took them to their DFW destination today. The aircraft was taken out of service for inspection for possible damage.

AA 9643 St John-MIA

January 25, 2015 - Flgihtradar24 shows an AA 767 departing St John at 21:11 due in MIA at 0:29. Is this the plane from MIA-MXP which encountered severe turbulance and forced to land at St John? Was the plane damaged that it had to return to MIA empty? I presume another plane was sent to take the pax to MXP ?

Yes that's the aircraft that diverted. I was reading on another airline forum (admittedly I am not sure of the rules about linking to other forums) about the event. Sounds like the cabin was a wreck... Wine and drinks spilled everywhere. The person in the post also stated there was blood throughout the cabin. Seems like it was a really serious encounter with turbulence. I'm glad that no one was more seriously injured than they were.

It sounds that way.

Now I'm really curious. Why swap out aircraft? Why fly back to Miami empty? Cargo?
I see the plane returned to service the next day to Dallas and is now on it's way to Honolulu so there was no apparent damage from turbulence. Wouldn't it have made more sense to return the empty aircraft to Dallas? I'm sure they know or have valid reasons but Cargo is the only thing I can think of. Maybe it couldn't be offloaded on to N-388AA in St John's.

The condition of the cabin would be a reason for it to return to MIA and not continue on. Nothing mechanical but the mess there would be important to address.

Maybe the crew had to get back to their bases?

Makes me think of Jules and Vincent cleaning the car on Pulp Fiction.

Too soon?
