THE POWER OF 25

摘要

Without Part 25 of the Federal Aviation Regulations, airline passengers might feel a little less confident in the safety of their ride. You may be relieved to know, for example, that each critical "removable bolt, screw, nut, pin, or other removable fastener" on your airliner "must include two separate locking devices." The FARs are rules that govern all aviation activity-from commercial airliners to model rockets-in the United States. In covering airworthiness standards for transports with a maximum takeoff weight greater than 12,500 pounds, Part 25 applies to Boeing's 737 and later types, and the Airbus A300 series, airliners certified since February 1,1965, when most of the FARs were instituted.
