Narrative:
After being cleared for an IFR approach at approximately 4 DME from the airport in IMC; we heard a loud noise and encountered strong buffeting as we were handed off from approach to tower. While dealing with the in-flight emergency; we attempted to contact tower twice; but received no response. We elected to land without a landing clearance; as we were unable to determine the cause of the buffeting. After landing we cleared the runway onto a non-movement area and contacted the tower via telephone. Upon exiting the aircraft; a postflt inspection found right inboard leading edge damage consistent with the buffeting experienced in-flight. The communication radio was checked and found inoperative and replaced by maintenance. Callback conversation with reporter revealed the following information: the airframe buffeting was quite severe. After landing; there was significant damage noted to the leading edge. The bird strike opened a hole in the skin of the leading edge requiring maintenance action to repair it.

Title: A CV240 FLT CREW EXPERIENCED A BIRD STRIKE FOLLOWED BY AIRFRAME BUFFETING WHILE BEING VECTORED FOR APPROACH. THEY CONTINUED TO A LANDING WITHOUT CLEARANCE BECAUSE THEIR RADIO HAD FAILED.
Narrative: AFTER BEING CLRED FOR AN IFR APCH AT APPROX 4 DME FROM THE ARPT IN IMC; WE HEARD A LOUD NOISE AND ENCOUNTERED STRONG BUFFETING AS WE WERE HANDED OFF FROM APCH TO TWR. WHILE DEALING WITH THE INFLT EMER; WE ATTEMPTED TO CONTACT TWR TWICE; BUT RECEIVED NO RESPONSE. WE ELECTED TO LAND WITHOUT A LNDG CLRNC; AS WE WERE UNABLE TO DETERMINE THE CAUSE OF THE BUFFETING. AFTER LNDG WE CLRED THE RWY ONTO A NON-MOVEMENT AREA AND CONTACTED THE TWR VIA TELEPHONE. UPON EXITING THE ACFT; A POSTFLT INSPECTION FOUND R INBOARD LEADING EDGE DAMAGE CONSISTENT WITH THE BUFFETING EXPERIENCED INFLT. THE COM RADIO WAS CHKED AND FOUND INOP AND REPLACED BY MAINT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE AIRFRAME BUFFETING WAS QUITE SEVERE. AFTER LANDING; THERE WAS SIGNIFICANT DAMAGE NOTED TO THE LEADING EDGE. THE BIRD STRIKE OPENED A HOLE IN THE SKIN OF THE LEADING EDGE REQUIRING MAINTENANCE ACTION TO REPAIR IT.
