(-23) On 9/15/02, at 1:10 pm lakes air 5111, a BE-1900-D airliner operated by great lakes aviation ltd., was in the landing roll after landing on runway 27 at the Rock Springs airport (rks). At the same time, comanche N8822P a PA-24 was in the landing flare on approach to runway 21 at rks. As the two aircraft approached the intersection of runway 27 and runway 21, the pilot of the comanche applied power in an attempt to avoid lakes air 5111, passed 20 feet over the top of the airliner, stalled and crashed south of runway 27 and east of runway 21. Investigation disclosed the pilot in command of the comanche N8822P made radio calls on the common traffic advisory frequency, including reporting downwind, base and final for runway 21. Investigation also disclosed neither the pilot and passenger of the comanche N8822P, nor three witnesses on the ground heard lakes air 5111 transmit any radio calls on the CTAF (122.8). The captain of lakes air 5111 although admitting ot not receiving an airport advisory nor hearing any traffic on the frequency claimed he did transmit in the blind on CTAF giving his position at 20, 15, 10, 5 and short final. This was corroborated by the first officer.
