What happened? Complete

The American Airlines flight AA3729 is a scheduled domestic service that originates at Charleston International Airport in South Carolina and flies to Dallas-Fort Worth in Texas.
The small regional jet has 76 seats and is six years old.
After departing to the southwest, the flight made a right turn once over Georgia and headed northwest over Alabama.
The flight was cruising at 36,000 feet when it encountered turbulence rated as 'moderate to severe.' The aircraft lost its right-hand winglet! The crew advised
air traffic control of this, and then opted to make a diversion to Birmingham, Alabama.
Reaching Birmingham–Shuttlesworth International, the aircraft landed safely on the facility's 3,660-meter runway 24, 95 minutes after departing Charleston.
A replacement aircraft was subsequently dispatched to Birmingham to take passengers to their Dallas .

The role of winglets. Complete


Winglets are separate parts of the aircraft which are attached to the wing of the aircraft - rather than being a single piece with the wing. Up until this incident, we haven’t really heard of an aircraft losing a winglet! Indeed, when a winglet IS separated from an aircraft, it’s usually a much worse situation (such as a crash) and the least of its problems.
In case you didn’t already know, winglets are vertical extensions of wingtips that improve an aircraft's fuel efficiency and cruising range. This is done by reducing the aerodynamic drag associated with vortices that develop at the wingtips as the aircraft moves through the air.
Historically with some aircraft types, winglets were only an option that was available to airlines
to add or decline.
