Episode 46 – Propellers and Air Safety

November 19, 2020/in Episodes /by FSD

Prop strikes are pretty common. Even seemingly minor nicks and gouges can lead to major safety issues.

John and Greg focus on propellers as the “ugly stepsisters” of aircraft maintenance. They dive into an accident involving a LancAir 4P caused when a damaged prop leading to engine failure.

In his years of service as a mechanic, John has seen plenty of engine damage caused by prop strikes. Greg layers in accident investigation work to illustrate just how important propellers are for aircraft safety.

This episode challenges every mechanic and pilot to give more attention to the humble propeller. Any abnormalities are worthy of thorough investigation.

Episode 45 – Icing on Aircraft, Lessons from the Crash of AE 4184

November 11, 2020/in Episodes /by Jill Kurtz

Weather caused Flight 4182 to be in a holding pattern to land on October 31, 1994. Weather also triggered a fateful series of events that led to the loss of the aircraft and 68 lives.

John and Greg offer a minute by minute analysis of the cockpit voice recorder. They believe this was the event that woke the industry up to the effects of icing on aircraft.

The NTSB accident report focuses on communicating hazardous weather information to flightcrews, Federal regulations regarding aircraft icing, and training for icing events.

The accident is a reminder for pilots as the season of wintry weather conditions approaches. Be present in the cockpit mentally. Push away distractions and focus on the machine.

Episode 43 – NTSB Still Not Onsite, CO Pilot Makes Up the Rules

October 28, 2020/in Episodes /by Jill Kurtz

Episode 43

The NTSB is still not doing onsite accident investigations. A pilot landing in Colorado decides to ignore the rules. Long-term health impacts of COVID could impact pilots, mechanics and flight attendants. Greg and John focus on these topics in their latest episode.

A recent accident in Buffalo prompted two senators to write a letter to the NTSB asking for an onsite investigation. The Board responded that they are not visiting accident scenes and deferred to the FAA for on-scene information gathering.

Greg and John continue to call on the NTSB to do its mandated job. They discuss the impact on aviation safety now and into the future.
This episode also analyzes a midair collision involving a Beech A36 Bonanza and a Robinson R44 Raven II in 2018 at Northern Colorado Regional Airport. The Beech pilot chose to set aside the rules and flew over the Robinson with disastrous results.

They wrap up with a discussion of COVID. People with even minor cases are reporting loss of taste and brain fog. Sense of smell is important to just about every aviation role on the ground and in the air. Clear thinking and decision-making are just as important.

Episode 42 – Is the NTSB Obsolete?

October 14, 2020/in Episodes /by FSD

The NTSB is considered a non-essential service and on-site accident investigations have been suspended during COVID-19. With no one on site to gather facts and evidence, John and Greg ask if the NTSB is needed anymore.

Even before the pandemic, the agency had an increasing case backlog. Reports that have been issued recently are incomplete and offer scant safety insight.

John and Greg find the recent NTSB reports inadequate to identify risks and determine effective mitigation. The reports lack the evidence to support the stated probable causes and offer little safety insight.

As John and Greg celebrate the one-year anniversary of Flight Safety Detectives, they use their straight-talking platform to call out the agency they have both proudly served for failing to do its job.

Episode 41 – End of a Long Day and Weather Add Up to Disaster

October 7, 2020/in Episodes /by Jill Kurtz

Greg and John examine the transcript of the cockpit voice recorder from American Flight 1420, a MD-80 that crashed at Little Rock Airport in 1999. Greg served as the NTSB investigator in charge (IIC) and John was part of the headquarters support team.

The 30-min recording reveals the pilots were racing the weather as well as fatigue from a long workday. John and Greg walk through the conversation reflected in the recording, highlighting how different decisions could have changed the deadly outcome.

They offer insights beyond the words of the transcript. What isn’t said and done is as compelling as what is documented in the CVR.

Greg and John discuss the process of looking at the aftermath to determine the cause and what could be learned. Findings led to checklist and operational procedures changes as well as configuration updates at the Little Rock airport.

Episode 40 – Assumptions and Expectations Can Kill

September 30, 2020/in Episodes /by Jill Kurtz

Assumptions and expectations in all roles in aviation often lead to the most serious accidents. John and Greg share anecdotes that illustrate the point.

This is a trying time for air travel and air safety. Greg and John are frustrated by the growing number of accidents that are not being investigated by either the NTSB or FAA. They wonder out loud why investigators, who have ample biohazard training, are not able to visit accident scenes to do their job?

Special focus is on American Flight 1420, a MD-80 that crashed at Little Rock Airport in 1999. Greg served as the NTSB investigator in charge (IIC) and John was part of the headquarters support team.

Listen to this wind up to Episode 41, which will dissect the cockpit voice recorder recovered from the Flight 1420 crash site.

Episode 39 – Accident Shows Importance of Pilot and Mechanic Communication

September 23, 2020/in Episodes /by FSD

John and Greg often make the point that flight safety involves both hangar and cockpit. This episode illustrates the point.

They walk through an accident involving a Cessna 177 Cardinal. The plane was in for annual maintenance. Although the mechanic had signed off in the logbook, the final run up was not completed before the pilot retrieved the plane.

The plane crashed shortly after takeoff. The investigation found no oil left in the engine. A loose oil cooler line suspected.

John and Greg highlight the need for mechanic and pilot to share information. Each individually has due diligence responsibilities as well as a shared responsibility to communicate.

Episode 38 – Merion Air Disaster Revisited

September 16, 2020/in Episodes /by FSD

When a Piper Aerostar collided in mid-air with a Bell 412 helicopter over an elementary school in Lower Merion Township, Pennsylvania, in 1991 Greg Feith was among the first investigators on the scene. Greg and John revisit the investigation to highlight NTSB findings that are relevant for pilots today.

The accident started the NTSB discussion and definition of aeronautical decision making. ADM is an important component of safe flying, in the cockpit and the hangar.

In the 1991 accident, five people in both aircraft were killed, including United States Senator John Heinz. Two school children on the ground were also killed by falling debris. More people on the ground were injured.

Greg describes the heartbreaking scene as well as the challenges of recovering evidence from a large debris field. Calling this a tragic event resulting from a “series of simple errors,” Greg talks about the role of crew experience, pilot communication and other notable factors.

Episode 37 – Minute-by-Minute Examination of ValuJet Flight 592’s Electronic Witness

September 9, 2020/in Episodes /by FSD

The cockpit voice recorder is called the “electronic witness” by crash investigators. In this episode, John and Greg walk through the CVR recovered during the investigation of ValuJet Flight 592 that crashed in the Everglades.

The CVR captures conversations. It also documents ambient noises that offer clues, especially when aligned with information from the flight data recorder.

Greg and John offer insight into what was learned from the CVR. Routine discussions quickly changed with the call of “fire” at 14:10. The recording shows rapid-fire issues unfolding. It chillingly shows that all on board seem to have succumbed to smoke asphyxiation before the plane crashed.

This second-by-second analysis expands on Episode 30 addressing listener questions and interest in detailed CVR analysis.
