Narrative:

Approaching glideslope intercept for ILS 10 approach at mtpp at 4;000 ft; 15 flaps; 200 KTS; selected 160 KTS in speed window; autothrottles went to idle; autopilot started down glideslope; surface winds were 090/14 gusting to 21. Encountered a brief gust of wind/updraft; aircraft speed briefly increased to 213; above the flap limitation for flaps 15; speed indicator flashed red for a few seconds; disconnected autopilot; increased pitch to decrease airspeed as throttles were already at idle. Speed immediately decreased below 200 KTS again. Total event time was 3-5 seconds.

Title: An air carrier on the MTPP Runway 10 ILS encountered a brief windshear which caused a speed increase and a flap overspeed while the autopilot and autothrottles to disengaged to stabilize the aircraft.
