Narrative:

In shooting the ILS-27 approach to khgr, we picked up some air frame ice. No sense that flying qualities had changed. From 2500 ft MSL to touchdown, accumulated ice (rime) began to melt. We used no flaps and about 90 KTS. At about 80 KTS and 20 ft above ground, aircraft stalled and bounced twice, right gear bent at axle on gear leg, and aircraft went off runway into soggy grass. On landing, ice on leading edge of wing and stabilator. Probably 1/4 inch thick. I have never landed with ice. We did no flaps and kept speed up. Stall warning was probably frozen. 20/20 hindsight: we should have flown in 0 degree and higher temperatures to melt all ice before landing.

Title: AN SMA LANDED HARD AND BENT THE LNDG GEAR AFTER PICKING UP A LOAD OF AIRFRAME ICE.

Narrative: IN SHOOTING THE ILS-27 APCH TO KHGR, WE PICKED UP SOME AIR FRAME ICE. NO SENSE THAT FLYING QUALITIES HAD CHANGED. FROM 2500 FT MSL TO TOUCHDOWN, ACCUMULATED ICE (RIME) BEGAN TO MELT. WE USED NO FLAPS AND ABOUT 90 KTS. AT ABOUT 80 KTS AND 20 FT ABOVE GND, ACFT STALLED AND BOUNCED TWICE, R GEAR BENT AT AXLE ON GEAR LEG, AND ACFT WENT OFF RWY INTO SOGGY GRASS. ON LNDG, ICE ON LEADING EDGE OF WING AND STABILATOR. PROBABLY 1/4 INCH THICK. I HAVE NEVER LANDED WITH ICE. WE DID NO FLAPS AND KEPT SPD UP. STALL WARNING WAS PROBABLY FROZEN. 20/20 HINDSIGHT: WE SHOULD HAVE FLOWN IN 0 DEG AND HIGHER TEMPS TO MELT ALL ICE BEFORE LNDG.
