AD 2013-11-16 max permissable altitude is limited to FL340

(c) Applicability​
This AD applies to Hawker Beechcraft Corporation (Type Certificate Previously Held by
Raytheon Aircraft Company) Model BAe.125 Series 800A (including C-29A and U-125), and 800B
airplanes; and Model Hawker 800 (including variant U-125A) and 800XP airplanes; certificated in
any category; modified by Aviation Partners Inc. Supplemental Type Certificate (STC) ST01411SE
(http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/1b3a5d9052d875c0862577a700704​
eb6/$FILE/ST01411SE.pdf).
e) Unsafe Condition​
This AD was prompted by reports of several instances of severe vibration and wing/aileron
oscillation due to lack of sufficient flutter margin with winglets installed. We are issuing this AD to
prevent vibration and wing/aileron oscillations, which could cause structural damage or lead to
divergent flutter, and result in loss of integrity of the wing, loss of control of the airplane, and inflight​
breakup.


 
there is a youtube video of this. looks rather exciting.
 
Sure looks like a super quick way to get the mechanical/cable operated airlerons flapping like that.
 
They should have brought a Cirrus BRS with them
 
Well at least it was caught this way and not with a failure of the structure resulting in a crash that has everyone scratching their heads.
 
This STC has been out a few years now. I'm sure there are at least 20 of them in service
