Summary

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.

(a)(1)A person may not operate a covered helicopter in United States airspace unless the design of the helicopter is certified by the Administrator of the Federal Aviation Administration to—

(B)employ other means acceptable to the Administrator to provide an equivalent level of fuel system crash resistance.
(2)In this subsection, the term “covered helicopter” means a helicopter not otherwise required to comply with section 27.952, section 27.963, and section 27.975, or section 29.952, section 29.963, and section 29.975 of title 14, Code of Federal Regulations as in effect on the date of enactment of this section for which manufacture was completed, as determined by the Administrator, on or after the date that is 18 months after the date of enactment of this section.
(b)The Administrator shall—
(1)expedite the certification and validation of United States and foreign type designs and retrofit kits that improve fuel system crashworthiness; and
(2)not later than 180 days after the date of enactment of this section, and periodically thereafter, issue a bulletin to—
(A)inform helicopter owners and operators of available modifications to improve fuel system crashworthiness; and
(B)urge that such modifications be installed as soon as practicable.
(c)Nothing in this section may be construed to affect the operation of a helicopter by the Department of Defense.
(d)A helicopter issued an experimental certificate under section 21.191 of title 14, Code of Federal Regulations (or any successor regulations), or operating under a Special Flight Permit issued under section 21.197 of title 14, Code of Federal Regulations (or any successor regulations), is excepted from the requirements of this section.
