Narrative:

Arriving at our home base airport, we encountered rain showers, icing, moderate turbulence, wind shear etc associated with a fast moving cold front. We were receiving vectors for the ILS plus using radar to avoid heavy rain showers! Approach advised that we would be vectored through the localizer at that time my speed was 200 KTS plus a tail wind of 70 KTS. At 4000 ft, ATC then turned us in to the localizer before going through it. Trying to slow down and get down and turn things were busy plus watching the radar. Also ATC was telling other aircraft about a 'target' in area of IMC with no transponder so we also were checking our TCASII. Upon turning I hit a severe down draft and started losing altitude very fast. I applied power. Pulled the nose up about the time I came out of it. That action put G's on us and the passenger but we still planned to salvage this approach. Mind fix was we don't want to be out here any longer than necessary. ATC (approach) cleared us for the approach. I was established on the ILS back to proper altitude of 2500 and going down to 2000 ft with the shear. Still fast we lowered the gear at which time a red light on the master caution panel flickered. It was so turbulent neither my copilot or I could read which one it was. Going by the outer compass locator final flaps were selected to the quartering tail wind of 40 plus KTS airspeed. Gain and loss was 15-20 KTS plus or minus. Wild ride. Wind on the ground was 10-15 KTS left quartering head wind. After getting on the ground after such a wild ride, my copilot looked at me when we were taxiing that he forgot to switch over to the tower for our landing clearance. We landed with no clearance. We contacted the tower then and she asked us had gso approach told us to switch over. Neither of us remembered hearing such but that is no excuse. She told us we needed to get a clearance and we said roger. We were loaded up and the copilot forgot and I missed it but we were flying the airplane. Still no excuse but I can't tell you how sick I felt when he told me that. He is an experienced pilot with several type ratings.

Title: CORP ACFT ENCOUNTERS SEVERE TURB AND WIND SHEAR ON FINAL APCH. NEGLECT CONTACT TWR.

Narrative: ARRIVING AT OUR HOME BASE ARPT, WE ENCOUNTERED RAIN SHOWERS, ICING, MODERATE TURB, WIND SHEAR ETC ASSOCIATED WITH A FAST MOVING COLD FRONT. WE WERE RECEIVING VECTORS FOR THE ILS PLUS USING RADAR TO AVOID HVY RAIN SHOWERS! APCH ADVISED THAT WE WOULD BE VECTORED THROUGH THE LOC AT THAT TIME MY SPD WAS 200 KTS PLUS A TAIL WIND OF 70 KTS. AT 4000 FT, ATC THEN TURNED US IN TO THE LOC BEFORE GOING THROUGH IT. TRYING TO SLOW DOWN AND GET DOWN AND TURN THINGS WERE BUSY PLUS WATCHING THE RADAR. ALSO ATC WAS TELLING OTHER ACFT ABOUT A 'TARGET' IN AREA OF IMC WITH NO TRANSPONDER SO WE ALSO WERE CHKING OUR TCASII. UPON TURNING I HIT A SEVERE DOWN DRAFT AND STARTED LOSING ALT VERY FAST. I APPLIED PWR. PULLED THE NOSE UP ABOUT THE TIME I CAME OUT OF IT. THAT ACTION PUT G'S ON US AND THE PAX BUT WE STILL PLANNED TO SALVAGE THIS APCH. MIND FIX WAS WE DON'T WANT TO BE OUT HERE ANY LONGER THAN NECESSARY. ATC (APCH) CLRED US FOR THE APCH. I WAS ESTABLISHED ON THE ILS BACK TO PROPER ALT OF 2500 AND GOING DOWN TO 2000 FT WITH THE SHEAR. STILL FAST WE LOWERED THE GEAR AT WHICH TIME A RED LIGHT ON THE MASTER CAUTION PANEL FLICKERED. IT WAS SO TURBULENT NEITHER MY COPLT OR I COULD READ WHICH ONE IT WAS. GOING BY THE OUTER COMPASS LOCATOR FINAL FLAPS WERE SELECTED TO THE QUARTERING TAIL WIND OF 40 PLUS KTS AIRSPD. GAIN AND LOSS WAS 15-20 KTS PLUS OR MINUS. WILD RIDE. WIND ON THE GND WAS 10-15 KTS L QUARTERING HEAD WIND. AFTER GETTING ON THE GND AFTER SUCH A WILD RIDE, MY COPLT LOOKED AT ME WHEN WE WERE TAXIING THAT HE FORGOT TO SWITCH OVER TO THE TWR FOR OUR LNDG CLRNC. WE LANDED WITH NO CLRNC. WE CONTACTED THE TWR THEN AND SHE ASKED US HAD GSO APCH TOLD US TO SWITCH OVER. NEITHER OF US REMEMBERED HEARING SUCH BUT THAT IS NO EXCUSE. SHE TOLD US WE NEEDED TO GET A CLRNC AND WE SAID ROGER. WE WERE LOADED UP AND THE COPLT FORGOT AND I MISSED IT BUT WE WERE FLYING THE AIRPLANE. STILL NO EXCUSE BUT I CAN'T TELL YOU HOW SICK I FELT WHEN HE TOLD ME THAT. HE IS AN EXPERIENCED PLT WITH SEVERAL TYPE RATINGS.
