Table schema:
CREATE TABLE table_name_42 (constructor VARCHAR, driver VARCHAR, free_practice_driver_s_ VARCHAR, chassis VARCHAR)

Question: who is the constructor when the free practice driver(s) is n/a, the chassis is 005 and the driver is takuma sato?
SQL: SELECT constructor FROM table_name_42 WHERE free_practice_driver_s_ = "n/a" AND chassis = "005" AND driver = "takuma sato"
