(b) Content of forms The form developed under subsection (a)(1) for reporting an incident of smoke or fumes on board an aircraft shall include sections for the following information, if available at the time of the report: (1) Identification of the flight, the type of aircraft, the registration number of the aircraft, and the individual reporting the incident. (2) Information about the smoke or a fire, if relevant, including a description of the nature and apparent source of the smoke or fire. (3) Information about the fumes, including a description of the type, apparent source, smell, and visual consistency (if any) of the smoke or fumes. (4) Information about the location of the smoke or fumes. (5) Information about the engine manufacturer, engine type, the engine serial number, and the age of the engine. (6) Information about— (A) the phase of flight during which smoke or fumes were present; and (B) if the incident happened while the aircraft was on the ground, the location of the aircraft at the airport at the time of the incident. (7) Other observations about the smoke or fumes. (8) A description of symptoms reported by crew members and passengers. (9) Information with respect to whether crew members or passengers used, needed, or were administered supplemental or emergency oxygen. (10) Information regarding any effects on the operation of the flight. (11) Information about maintenance work conducted on the aircraft following the incident. (c) Public availability of smoke and fume event information (1) In general Not less frequently than quarterly and subject to paragraph (2), the Administrator of the Federal Aviation Administration shall compile, and make available to the public, statistics regarding the information obtained from the forms developed under subsection (a)(1) and submitted to the Federal Aviation Administration. (2) Website The Administrator shall develop a publicly available Internet website that includes the aggregate data required under paragraph (1) and a searchable database for the events reported to the Federal Aviation Administration under subsection (a)(2) that includes the following variables for each event: (A) Date. (B) Tail number. (C) Air carrier. (D) Phase of flight. (E) Location of fumes. (F) Description of fumes. (G) Aircraft type. (H) Engine type. (I) Oil type. (J) Deidentified narrative. (K) Cause or maintenance information if cause is not known. (L) Such other criteria as the Administrator considers appropriate. (3) Redaction Before making either individual event information or aggregate data available to the public under paragraph (1) or (2), the Administrator shall redact any personally identifiable information. 5. Investigations (a) In general Not later than 180 days after the date of the enactment of this Act, the Administrator of the Federal Aviation Administration shall prescribe regulations requiring the Federal Aviation Administration to conduct an investigation described in subsection (b), after a report is submitted to the Administration through the system for reporting incidents of smoke or fumes on board aircraft established under section 4(a)(2) and before the date that is 7 days after the incident. (b) Requirements for investigations An investigation described in this subsection shall include the following: (1) Gathering factual and standardized information from all flight attendants, pilots, aircraft maintenance technicians, airport first responders, emergency response teams, and medical doctors involved in the incident. (2) Gathering any reports submitted under section 4 with respect to the incident. (3) Gathering technical findings on any replaced, worn, missing, failed, or improperly serviced components that may have resulted in the incident. (4) Identifying the cause of the incident, if possible. (c) Participation of air carriers and collective bargaining representatives In conducting an investigation under this section, the Federal Aviation Administration shall— (1) consult with the commercial air carrier involved; (2) work in conjunction with the technical representatives of the air carrier; and (3) invite the participation of the collective bargaining representative of employees of the air carrier. 6. Air monitoring equipment (a) Requirement To include on commercial aircraft Not later than 180 days after the date of the enactment of this Act, the Administrator of the Federal Aviation Administration shall prescribe regulations requiring a commercial air carrier, by not later than one year after the regulations are published in the Federal Register— (1) to install and operate onboard carbon monoxide detectors that— (A) are situated in the air supply system to best enable pilots and maintenance technicians to locate the source or sources of air supply contamination; (B) continuously monitor carbon monoxide levels in the aircraft air supply system when the aircraft is in flight; and (C) alert the pilot and flight attendants in the event that carbon monoxide concentration is at or above 9 ppm; and (2) to have in place procedures to train the pilots to initiate standardized communication protocols, as soon as appropriate, with the flight attendants and controllers (as needed), and to apply their professional judgement based on onboard conditions, all in response to carbon monoxide concentration at or above 9 ppm. (b) Requirement for a pilot To report an alarm The regulations prescribed under subsection (a) shall require a pilot to submit a form through the system for reporting incidents of smoke or fumes on board aircraft established under section 4(a)(2) if the carbon monoxide concentration is at or above 9 ppm at any time during flight. (c) Inclusion of information relating to carbon monoxide detectors in aircraft manuals Not later than one year after the date of the enactment of this Act, the Administrator of the Federal Aviation Administration shall prescribe regulations requiring an aircraft manufacturer that manufactures aircraft for commercial air carriers to include procedures for responding to alarms from carbon monoxide detectors during normal and nonstandard operations in the flight operator’s manual for each such aircraft produced by the manufacturer.
