Factual narrative
ACFT HAD A LONG DESCENT FROM CRUISE ALT OF 7500' MSL AT REDUCED POWER SETTING DUE TO PLT'S DESIRE TO AVOID THE MODERATE TURBULENCE AT LOWER ALTITUDES. ON SHORT FINAL, OVER TALL TREES, THE ACFT ENCOUNTERED A DOWNDRAFT. THE PLT STATED THAT WHEN HE APPLIED POWER TO ARREST THE DESCENT RATE, THE ENG HESITATED AND CONSEQUENTLY THE ACFT ENTERED THE TOPS OF THE TREES. WINDS WERE VARIABLE FROM 160 TO 230 DEGS AT 15 TO 26 KTS. HILLY TERRAIN IN THE VICINITY OF THE AIRPORT POSSIBLY CONTRIBUTED TO MECHANICAL TURBULENCE. PLT GAVE NO INDICATION THAT HE EVER ADDED POWER AT ANY TIME DURING THE DESCENT OR INITIAL APPROACH. ICING PROBABILITY CHARTS INDICATE THAT THE CONDITIONS WERE PRESENT FOR THE FORMATION OF INDUCTION ICING AT GLIDE POWER SETTINGS.
