Narrative:

During approach to landing, on attempt to extend landing gear, right main failed to lock, due to bolt which attaches push rod to gear mechanism shearing. Had no down light for right main gear. Landing was normal. Aircraft almost stopped. Pilot decided light switch or circuit was defective, then applied power to proceed to taxi area. Made right turn. Right main gear collapsed. Pilot should have stopped on runway, shut down and requested maintenance, but did not since maintenance not normally available on saturday afternoon, and perceived pressure to clear runway to allow airline traffic to land.
