Bill Summary
The "Safe Air on Airplanes Act" is a legislative proposal aimed at phasing out the use of bleed air systems in certain aircraft to enhance air quality and safety for passengers and crew. The bill mandates the Administrator of the Federal Aviation Administration (FAA) to update existing regulations within six months of its enactment.
Key provisions include:
1. **Prohibition on New Designs**: New turbine and turbo-prop aircraft designs will be prohibited from incorporating bleed air systems.
2. **Air Quality Improvements**: Starting seven years after enactment, any newly manufactured aircraft equipped with bleed air systems must have filters or air cleaning devices that effectively remove harmful oil fumes and particulates.
3. **Phase-Out Schedule**: The bill establishes a timeline for phasing out bleed air systems in existing aircraft designs:
- 25% of such aircraft must be manufactured without bleed air systems within 10 years.
- 50% within 20 years.
- 100% within 30 years.
A "bleed air system" is defined as a system that uses compressed air taken from an aircraft engine or auxiliary power unit and is used for passenger ventilation and other applications. The legislation seeks to improve the health and safety of air travel by reducing exposure to potentially harmful airborne contaminants.
Possible Impacts
The "Safe Air on Airplanes Act" could affect people in several significant ways:
1. **Improved Air Quality for Passengers and Crew**: By phasing out bleed air systems and requiring new aircraft to include filters and air cleaning devices, the legislation aims to reduce exposure to harmful oil fumes and particulate matter. This change could lead to better air quality in the cabin, potentially decreasing health risks for passengers and crew members who are regularly exposed to these airborne contaminants during flights.
2. **Economic Impact on Aircraft Manufacturers**: The transition away from bleed air systems could require significant investment in research and development for manufacturers to create new aircraft designs and technologies that comply with the updated regulations. This could lead to increased costs for manufacturers, which might be passed on to airlines and, ultimately, consumers through higher ticket prices. Additionally, manufacturers may face economic challenges if they need to retrofit existing aircraft to meet these new standards.
3. **Regulatory Compliance and Industry Transition**: The requirements set forth in the legislation create a clear timeline for the aviation industry to adapt to new regulations. This transition may necessitate retraining for engineers and technicians involved in aircraft design and maintenance. Employees in the aviation sector might experience job shifts, either due to new roles created by the adoption of new technologies or potential job losses if companies struggle to meet the new standards and downsize operations.

_______________________________________________________________________
A BILL
To require the Administrator of the Federal Aviation Administration
shall update the regulations to issue regulations to phase out the use
of bleed air systems in certain aircraft, and for other purposes.
Be it enacted by the Senate and House of Representatives of the
United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
This Act may be cited as the ``Safe Air on Airplanes Act''.
SEC. 2. REGULATIONS ON BLEED AIR SYSTEMS IN CERTAIN AIRCRAFT.
(a) Regulations Required.--Not later than 6 months after the date
of enactment of this Act, the Administrator of the Federal Aviation
Administration shall update the regulations under part 25 of title 14,
Code of Federal Regulations, and any other applicable regulations, to--
(1) prohibit new type certified turbine and turbo-prop
aircraft designs from using bleed air systems;
(2) require that, beginning on the date that is 7 years
after the date of enactment of this Act, any bleed air system
in a newly manufactured aircraft is fitted with a filter or
combination of filter and air cleaning device designed and
demonstrated to remove gaseous and particulate components of
oil fumes; and
(3) provide for a phase-out of the use of bleed air systems
in the manufacture of existing type designs of turbine and
turbo-prop driven aircraft according to the following:
(A) Not later than 10 years after the date of
enactment of this Act, 25 percent of such aircraft
shall be manufactured without bleed air systems.
(B) Not later than 20 years after the date of
enactment of this Act, 50 percent of such aircraft
shall be manufactured without bleed air systems.
(C) Not later than 30 years after the date of
enactment of this Act, 100 percent of such aircraft
shall be manufactured without bleed air systems.
(b) Definition of Bleed Air System.--In this Act, the term ``bleed
air system'' means an air system that--
(1) uses compressed air that is taken from an aircraft
engine, or auxiliary power unite compressor stage, that is
upstream of the combustion chamber or on a shaft driven by a
turbine engine; and
(2) provides pressurized air to the aircraft pneumatic
system that passengers or crew could foreseeably inhale or come
in contact with during the operation of the aircraft for
applications including ventilation.
