Title 49 › Subtitle SUBTITLE VII— - AVIATION PROGRAMS › Part PART A— - AIR COMMERCE AND SAFETY › Subpart subpart iii— - safety › Chapter CHAPTER 447— - SAFETY REGULATION › § 44737
Helicopters may not be flown in U.S. airspace unless the FAA says their design meets certain fuel‑system crash‑resistance rules that were in effect when the law was passed, or unless the FAA approves other methods that give the same level of protection. Covered helicopter: a helicopter that was not already required to meet those older rules and whose manufacture was finished on or after the date that is 18 months after the law was passed, as decided by the FAA. The FAA must speed up approval of U.S. and foreign designs and retrofit kits that make fuel systems safer in a crash. Within 180 days after the law and then periodically, the FAA must issue a bulletin telling owners and operators what improvements are available and urging they be installed as soon as practicable. These rules do not affect Department of Defense helicopter operations. Helicopters with experimental certificates or operating under special flight permits are not covered by these requirements.
