Guy drops the F bomb but rightfully so. Keep the volume down for virgin ears.

What's the story behind this?

What's the story behind this?

@DPApilot was flying it.

Correct me if I'm wrong, but would the problem here be flying too slow? or too fast? Would adding aileron pressure and rolling left and right help?

Aileron flutter on what appears to be a Hawker 800XP with API winglets. This oscillation has been reported on 800XP and 850XPs with API winglets, with HBC winglets, and with no winglets at all operating above M0.73 and 33,000 feet. When the aircraft is slowed and/or descended, the flutter ceases.

On 11/27/2013 the FAA released Special Airworthiness Information Bulletin NM-14-05.

"Investigation of these incidents revealed missing aileron bushings, low cable tensions, and improperly installed brackets. After the operators corrected the airplanes to the type design configuration, as defined per the existing maintenance manuals, the oscillations did not recur."

Well that's effing terrifying. "Yeah, I guess when we install the wings correctly, they don't fall apart. We should do that." Jesus.
