A dizzying range of factors led to last year's deadly collision between an Army helicopter and a regional jet over the Potomac River, per the final National Transportation Safety Board report out Tuesday.
Why it matters: As is often the case with major aviation disasters, many smaller issues — each perhaps benign on their own — added up to a tragedy of the grandest scale, leaving 67 people dead.
Driving the news: The NTSB's final report cites a wide array of causal factors, including the FAA's placement of a helicopter route so close to an aircraft approach path into Ronald Reagan Washington National Airport, also called DCA.
Other factors, per the NTSB...
- Air traffic's over-reliance on visual separation (when pilots keep a safe distance from other aircraft on their own — which is particularly tough at night in busy airspace, when the DCA midair occurred).
- High workload at DCA's control tower, which fueled a loss of situational awareness and "degraded performance."
- An "unsustainable airport arrival rate" at the ever-busy DCA.
- The FAA's failure to strengthen requirements for ADS-B In, a technology that helps pilots maintain awareness of nearby aircraft.
- The U.S. Army's "lack of a fully implemented safety management system."
Between the lines: Also notable is the NTSB's finding that blocked radio transmissions between pilots and controllers contributed to the disaster.
- Controllers' radio frequencies are often busy with many pilots at once. Vital communications can be blocked if pilots or controllers "step" on one another by transmitting simultaneously.
What's next: The report comes with a litany of recommendations for the FAA, Army and other stakeholders.
- But the NTSB can only investigate and make suggestions. It's up to the FAA and others to implement its ideas — often a lengthy and bureaucratic process.
The bottom line: "Sometimes there is progress, but it takes years. Other times, decades. All that's to say: Enduring change can take time. Making the system-wide changes we need doesn't come easy, but we must make them," NTSB chair Jennifer Homendy said in a statement accompanying the report.
- "And we should do so BEFORE people die."
