Summary
A Sikorsky S-92A search and rescue training flight encountered unexpected turbulence, probably associated with mountain waves near the Sperrin Mountains, and exceeded its airspeed limit. The report examines recorded flight data, wind-calculation delays and meteorological evidence. A precautionary diversion followed; inspection defects were considered probably pre-existing by the manufacturer’s representative.
