Narrative:

On departure from ZZZ single pilot with no passengers under part 91; IMC; light rain and smooth air climbing through 11;400 feet to assigned altitude; I encountered microburst. The aircraft indicated a stabilized climb speed of 125 kts the instantaneously indicated about 260 kts (vne is 188 kts) of pfd 1; pfd 2 and standby instruments. What I believe was torsional tail flutter also occurred. The microburst or wind shear event lasted about thirty seconds then normal flight returned.upon safely landing I contacted piper; for guidance on appropriate inspection as outlined by piper factory engineers. The safety issue of potential structural damage to my aircraft; a piper M500 has never been addressed by company nor aircraft manufacturer after several documented verbal and written correspondence with both parties. With the history of structural failure of the PA-46 series; especially; the turbine powered versions I would expect some form of established engineering order readily available for owners and operators of this aircraft because of the performance envelope.we have gone to extremes to find a corrective action in the form of reasonably inspection to assure safety of flight; but company and aircraft manufacturer are refusing to support their product thus creating a safety problem that will most likely present in the future as an inflight structural failure. Their position is that if they handle or touch the aircraft; when there is structural failure both parties will have shared financial liability. As of today; the companies' position is stating aircraft X is safe for flight without any further inspections.these companies are voluntarily negligent in assuring the structural integrity of aircraft X as is required by crash fire rescue equipment's; federal and state law. Please assess the urgency this matter needs.
