F The pilot reported that as the aircraft descended through 300 ft on final approach, windshear and an increase in the rate of descent was experienced. He applied power to arrest the rate of descent then reduced the power setting to idle. The aircraft landed heavily and bounced, the pilot attempted to take corrective action but the aircraft again landed heavily. The aircraft was taxied to the parking area where the damage was noted. The endorsement completed earlier that day, was the pilot's first flight in a civil aircraft and this flight was his first solo in a multi-engined aircraft. Although endorsed on a heavy transport type, the pilot was projected into an environment beyond his level of experience, due to the single pilot workload being higher than that to which he was accustomed. The approach was steeper and 30 knots faster than recommended and a high power setting was used. The approach was made into the sunset and visibility was further impaired by a dirty windscreen.
