Episode 40 examines a wide range of recent accidents before focusing on a troubling pattern: pilots flying with impairing OTC medications or drugs in their systems.

Max Trescott and Rob Mark begin with a fatal nighttime crash of C-GPTX, a Cessna 172 in Saskatchewan and the runway overrun of Eclipse 500 N816KD at Auburn, California. They also discuss Beech Travel Air N529RB, which was flown in repeated low-level circles about 100 feet above the Pacific before crashing into the ocean, raising the possibility of an intentional act.

Preliminary reports include Piper Seneca N212ML, lost near the Bahamas in convective weather; C-IFBY, a Para-Ski VX powered parachute carrying three people even though its U.S. operation did not qualify under Part 103; and Lake Amphibian N6185V, which apparently ran out of fuel just miles from Ithaca.

Final reports include a fatal VFR-into-IMC accident involving N9626K, a Piper PA-28 and the crash of Ameriflight Beech C99 N130GP after a partial engine-power loss.

The episode closes with four fatal-accident reports involving the active ingredients in Benadryl and Zyrtec, or cyclobenzaprine, cannabis, or morphine. The takeaway is simple: “over the counter” does not mean “safe to fly,” and pilots need to understand the FAA’s medication waiting-period guidance. Max also explains why medication effects can undermine a pilot’s own self-assessment.

New information from the NTSB is filling in the final seconds of the Amazon Prime Air Boeing 767 crash in Miami. The agency’s summary of the cockpit voice recorder shows repeated concerns about excessive speed, followed by touchdown and then, 16 seconds later, a call for a go-around. The brakes were released at a ground speed of 120 knots and go-around thrust was applied before the attempt was abandoned. Recorded data showed no indication that the speed brakes or thrust reversers were deployed.

Max Trescott also revisits his ADS-B analysis of Flight 7598 and explains why he believes an automation surprise involving the Boeing 767’s vertical modes may have contributed to the airplane becoming high and fast.

Then Max and Rob Mark examine the fatal KNBC AS350B2 helicopter crash in Los Angeles, including ADS-B evidence and reports of a possible low-rotor-RPM warning.

Other accidents include N734ZK, a Cessna 172N crash at Montgomery-Gibbs Executive Airport, N9485P, a fatal Piper Comanche accident at a short Alaska runway, N93R, a Lockheed 12A that took off with full flaps, a fuel-exhaustion accident involving N413AW, a Pipistrel Alpha, and N188PC, a Pilatus PC-12 loss of control in IMC.

The episode closes with a story from the NASA ASRS Callback newsletter about a Cirrus pilot’s successful recovery from a dangerous distraction in instrument conditions.

An Amazon Prime Air Boeing 767 crashes after overrunning Runway 30 at Miami International Airport—and ADS-B data contains an important clue about how the approach became unstable.

In this episode, we analyze the September 6 crash of Prime Air Flight 7598, operated by 21 Air with Boeing 767 N1997A. The flight from San Juan initially followed an almost perfect three-degree approach toward Miami. But approximately five miles from the runway, the aircraft unexpectedly leveled near 1,600 feet.

The ADS-B data shows that 1,600 feet had been entered as the selected altitude much earlier in the descent. That raises the possibility of an automation surprise, although another possibility is that the crew leveled inadvertently after disconnecting the autopilot to hand-fly.

The crew then attempted to recover using a descent approaching twice the normal glide angle. The 767 crossed the displaced threshold around 175 knots, apparently touched down near 160 knots, and was still traveling about 110 knots when it left the runway.

We also examine a fatal PC-12 spatial-disorientation accident, new evidence of helicopter wake turbulence in a Cessna 150 collision, and a troubling student-pilot night CFIT accident involving a CFI cross-country endorsement.
