A Mesa Airlines Canadair CRJ-900 on behalf of US Airways, registration N246LR performing flight YV-5617/US-5617 from Phoenix,AZ to Des Moines,IA (USA) with 80 people on board, was enroute at FL370 about 80nm southwest of McCook,NE (USA) at about 21:15Z when the aircraft encountered turbulence causing the aircraft to deviate from assigned flight level by about 100 feet. The aircraft continued to Des Moines for a safe landing about 70 minutes later.

The FAA reported 5 passengers received minor and another passenger unknown injuries.

On Apr 9th 2016 the NTSB released their final report concluding the probable cause of the accident was:

inadvertent encounter with turbulence while deviating around an area of known convective activity.

The NTSB reported the fasten seat belt signs were illuminated about 2 minutes prior to the turbulence encounter while the aircraft was deviating around weather. The aircraft was level at FL370 at 258 KIAS, whe the airspeed began fluctuating between 268 and 244 KIAS over the next 10 seconds, the vertical acceleration fluctuated between -0.55G and +1.64G and the lateral acceleration fluctuated between -0.13G and +0.23G.

A flight attendant just making an announcement regarding the seat belt signs hit her head on the back of the jumpseat and observed a passenger was thrown against the ceiling and then down to the floor, another passenger displaced from her seat hit her head against the overhead lockers. A passenger in the aft lavatory was also thrown against the ceiling and wall, two other passengers were displaced from their seats.

There were one serious and four minor injuries. Three passengers were taken to a hospital, one of them with a dislocated shoulder and a chipped bone.
