Max interviews Jeff Guzzetti, a former NTSB investigator, to discuss the Max interviews Jeff Guzzetti, an aviation safety consultant and former NTSB investigator, for an in-depth discussion on aviation accident investigations. Given the recent high-profile aviation incidents, Max and Jeff explore the detailed processes followed by investigators to determine probable causes and prevent future accidents.

Jeff begins by explaining ICAO Annex 13, the international framework governing accident investigations. This document ensures global cooperation, allowing manufacturers, regulatory bodies, and investigators from different countries to collaborate. He also defines key terminology, distinguishing between “accidents,” “incidents,” and “serious incidents,” and explaining how these classifications determine the level of NTSB involvement.

The NTSB is required by Congress to investigate all civil aviation accidents in the U.S., but due to resource constraints, they rely on FAA inspectors to gather information for smaller accidents, particularly those without fatalities. Jeff explains how the NTSB prioritizes major accidents, dispatching a GO team with specialists in areas such as human performance, engines, and flight systems.

For larger accidents, Jeff describes the party system, where manufacturers, airlines, and regulatory agencies provide technical expertise under strict confidentiality rules. The NTSB oversees and controls the investigation, ensuring objective findings. Jeff recalls past incidents where parties were removed from investigations for violating confidentiality, such as when the National Air Traffic Controllers Association (NATCA) was dismissed for unauthorized press briefings.

Max and Jeff discuss the critical role of black boxes—cockpit voice recorders (CVRs) and flight data recorders (FDRs). Jeff details the process of retrieving these devices, particularly when submerged in water, and the careful procedures used to extract and analyze data. He also explains how modern aircraft and even smaller GA planes with avionics like the Garmin 1000 can provide investigators with vital flight data, even when traditional black boxes are not available.

The conversation shifts to the hazards investigators face at accident scenes, including biohazards, sharp wreckage, extreme environmental conditions, and even the dangers of inhaling carbon fiber particles from burned composite materials. Jeff describes safety protocols, including protective suits and respirators, to mitigate these risks.

Mental health challenges for investigators are also addressed. Repeated exposure to tragic accidents, particularly those involving children, can take a psychological toll. Jeff highlights the NTSB’s Employee Assistance Program (EAP), which offers support and counseling, and explains that many investigators develop coping mechanisms to continue their work effectively.

Regarding the recent mid-air collision near Washington, D.C., Max asks how the high-profile nature of the accident—occurring at an airport frequently used by lawmakers—might affect the investigation. Jeff believes this will lead to heightened scrutiny but also ensure a thorough and well-documented investigation. He outlines the expected timeline, with a preliminary factual report within a few weeks, possible public hearings within months, and a final report with probable cause conclusions in about 18-24 months.

Jeff warns against jumping to conclusions based on early evidence, emphasizing that accidents often have multiple contributing factors. He discusses cognitive biases in accident investigation, where even experienced investigators may initially focus on familiar patterns rather than objectively analyzing all available data.

Towards the end of the episode, Max and Jeff talk about opportunities for those interested in aviation accident investigation. Jeff describes his teaching role at USC’s Aviation Safety Program, where he educates students on accident investigation techniques, human factors, and safety management systems. He also shares insights from his consulting work and role as an NBC aviation analyst.

The episode concludes with Jeff encouraging listeners to stay engaged in aviation safety and avoid premature speculation about accidents. He emphasizes the value of thorough investigations in making aviation safer for everyone.
