Aircraft
Shortly after leveling off at FL410; and while still accelerating to cruise speed; I turned off the nacelle heat switches that had been used on the initial climb. This caused an increase in EPR; which resulted in an immediate right engine flameout due to the internal pressure change in the engine. We requested descent to FL200 for the engine re-start procedure. Center granted this request. We descended to below FL250; restarted the engine in accordance with the checklist procedure. We then requested climb to cruise altitude and completed the flight normally from that point. The aircraft remained in full control at all times.
When a Lear 25 pilot turned the right engine nacelle heat OFF after leveling and accelerating at FL410 it flamed out so during descent toward FL200 he restarted the engine and returned to FL410.
