    Letter to U.S. Senators Gorton and Murray Regarding Sea-Tac Airport Safety Issues

    ★
    In February 2000, the Regional Commission on Airport Affairs (RCAA) wrote to U.S. Senators Patty Murray and Slade Gorton urging an investigation into aviation safety concerns at Sea-Tac Airport, following a KIRO-TV news report that revealed hundreds of unreported near-misses, runway incursions, and mechanical problems documented in NASA AMES files. The RCAA argued that these hidden dangers raised serious questions about the Port of Seattle's plans to expand the airport with a third runway. The letter also requested a moratorium on expansion-related construction permits until a full safety investigation — ideally led by the FAA Inspector General — could be completed.

    NTSB Investigators Examining Aircraft Debris

    Two NTSB (National Transportation Safety Board) investigators, wearing agency-marked jackets, examine and recover a large aircraft door plug panel found on a residential lawn. The panel, which has a window cutout, is consistent with the door plug that detached from Alaska Airlines Flight 1282 (Boeing 737 MAX 9) in January 2024, with debris recovered in the Portland, Oregon area.

    Aircraft Engine Failure with Fire During Flight

    A Boeing 777 engine (Pratt & Whitney PW4000) is shown on fire and with its cowling torn away, photographed from a passenger window seat. This image is widely recognized as being from United Airlines Flight 328, which suffered an engine failure shortly after takeoff from Denver International Airport on February 20, 2021.

    FAA authority to change the 65 DNL noise contour

    Aviation noise consultant Vince Mestre explains to the Port of Seattle why changing the FAA's 65 DNL noise contour standard — the threshold used to determine acceptable aircraft noise near residential areas — would likely require an act of Congress rather than a simple regulatory update. The 65 DNL standard is embedded in at least three federal regulations and orders (CFR 14 Parts 150 and 161, and FAA Order 1050.1F), all of which trace their authority back to enabling legislation such as the Aviation Safety and Noise Abatement Act (ASNA) of 1978 and the Airport Noise and Capacity Act (ANCA) of 1990. Because the FAA's rulemaking authority is granted and bounded by those Congressional statutes, modifying ASNA would most likely be required before the FAA could formally lower or otherwise change the noise compatibility standard.

Issues

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
