Summary

Helicopters may not fly in U.S. airspace unless the FAA Administrator certifies the helicopter’s design either meets the fuel-system crash-resistance rules in 14 CFR (paragraphs (1), (2), (3), (5), and (6) of 27.952(a); 27.952(c); 27.952(f); 27.952(g); 27.963(g) with a 250‑pound minimum puncture force if drop‑tested in‑structure; 27.975(b); or paragraphs (1), (2), (3), (5), and (6) of 29.952(a); 29.952(c); 29.952(f); 29.952(g); 29.963(b) with the same 250‑pound allowance; and 29.975(a)(7) as they were on the date of enactment), or uses other FAA‑approved means that give an equivalent level of fuel‑system crash resistance. A "covered helicopter" is one not already required to meet those cited rules and whose manufacture was completed on or after the date that is 18 months after enactment. The FAA must speed up approval of U.S. and foreign type designs and retrofit kits that improve fuel‑system crashworthiness. Within 180 days after enactment, and periodically after that, the FAA must issue a bulletin telling owners and operators what modifications are available and urging they be installed as soon as practicable. These rules do not change how the Department of Defense operates helicopters. Helicopters with an experimental certificate under 14 CFR 21.191 or a Special Flight Permit under 14 CFR 21.197 are exempt.

(a)Prohibition.—
(1)In general.—
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—
(A)comply with the requirements applicable to the category of the helicopter under paragraphs (1), (2), (3), (5), and (6) of section 27.952(a), section 27.952(c), section 27.952(f), section 27.952(g), section 27.963(g) (but allowing for a minimum puncture force of 250 pounds if successfully drop tested in-structure), and section 27.975(b) or paragraphs (1), (2), (3), (5), and (6) of section 29.952(a), section 29.952(c), section 29.952(f), section 29.952(g), section 29.963(b) (but allowing for a minimum puncture force of 250 pounds if successfully drop tested in-structure), and 29.975(a)(7) of title 14, Code of Federal Regulations, as in effect on the date of enactment of this section; or
(B)employ other means acceptable to the Administrator to provide an equivalent level of fuel system crash resistance.
(2)Covered helicopter defined.—
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)Administrative Provisions.—
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)Rule of Construction.—
Nothing in this section may be construed to affect the operation of a helicopter by the Department of Defense.
(d)Exception.—
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.
