Title 49 › Subtitle SUBTITLE VII— AVIATION PROGRAMS › Part A— AIR COMMERCE AND SAFETY › Subpart iii— safety › Chapter 447— SAFETY REGULATION › § 44737
You may not fly a covered helicopter in U.S. airspace unless the FAA has approved its design as meeting fuel-tank crash-resistance rules that were in effect when the law passed, or the helicopter uses other FAA‑accepted ways that give the same protection. The FAA may allow a minimum puncture force of 250 pounds in certain drop tests if the tank passes an in-structure drop test. A "covered helicopter" means one that is not already required to meet those fuel-system rules and whose manufacture was finished on or after the date that is 18 months after this law took effect. The FAA must speed up approval of U.S. and foreign designs and retrofit kits that make fuel systems safer. Within 180 days after the law took effect, and then from time to time, the FAA must send out a bulletin to tell owners and operators what safety modifications are available and urge them to install those fixes as soon as practical. The rule does not change Department of Defense flight operations. Helicopters with experimental certificates or special flight permits are also exempt.
