Accident Probes

The recent partial shutdown of the U.S. federal government had a far-reaching impact on aviation, thanks to its parent Department of Transportation (DOT) being one of the agencies lacking an enacted appropriations bill for the current fiscal year. Since related agencies are tacked onto DOT spending bills, the NTSB also closed for the duration, delaying ongoing investigations and postponing new ones. (Our monthly listing of preliminary accident reports might look a bit strange until the NTSB has caught up with the backlog.)

I had an interesting experience following recent painting of my Cessna 182. I flew it back from the paint shop uneventfully enough, but after tying it down following that two-hour flight home, we had a windstorm with 50-knot gusts, and the wind put enough force on the right wingtip to cause the screws holding it in place to drop out. So, the wingtip peeled off, and smashed into the cowling, creating a dent/crease just forward of the windshield.

The aviation industry in recent years has highlighted loss of control in-flight (LOC-I) as the leading cause of general aviation fatal accidents. Many aviation organizations, including government agencies, have devoted considerable time and resources to target this problem and develop effective mitigations to reduce the number of LOC-I accidents. Much of that effort focuses on a pilot losing control, and how to train and equip to prevent it, because its the final event in the accident chain.

It fascinates me that many GA pilots of single-engine airplanes cruise at such low altitudes. Theyre apparently oblivious to the fact that they are flying behind a single engine and if it fails you are on short final to somewhere! Extra altitude not only increases your radius of action, it also adds extra time for trouble shooting (which might eliminate the initial problem altogether) and increases the probability that a Mayday call might be heard. The side benefits include greater aircraft efficiency, cooler temperatures in the summer and possibly a smoother ride, in addition to less-congested airspace. Those long, low, flat, power-on final approaches can put you in the trees if your engine even coughs on short final. Keep a little energy in the bank and make it SOP to shoot for a reasonable aiming point on the runway.

I ts widely accepted that having good situational awareness is vital to safe and efficient flying. But what does situational awareness even mean? How do we develop and maintain the good kind? How do we fit ourselves into the big picture, and why is it important to do so? And once we understand these aspects of situational awareness, how can we use it to make things easier? On three recent flights, I feel I had a high level of situational awareness and used it to make a difference. In one I used my knowledge of my place in the big picture to help another pilot. In the second I used it to help myself. In the third I used it to eliminate a possible delay on an approach. Heres what Im talking about.

The primary cause of a bounced landing is flaring too high above the runway, perhaps with too much speed. In our ideal, perfect landing, the airplane will quit flying just inches above the runway. Instead, a bounce results when the flare occurs a few feet above it, and the airplane has the energy-resulting from excess altitude, excess airspeed or both-to rebound back into the air. In any event, a bounce results when the airplane isnt finished flying.

The April 4, 2018, crash of a Piper PA-28R-201 Arrow V operated by Embry-Riddle Aeronautical University (ERAU) continues to have repercussions. Most recently, the FAA has published a proposed airworthiness directive (AD) that would require inspecting each main wing spar of a wide range of Piper airplanes. The proposed AD is a response to the ERAU crash, which involved the inflight separation of the Piper Arrows left wing. Both aboard died and the airplane was destroyed.

At FL400, the autopilot started porpoising and was turned off. Afterward, the aircraft would not trim properly. The crew diverted; it was difficult to keep it pitched down while descending. During the final phase of flight, the yoke was very difficult to input pitch changes, but was okay in the roll axis. After landing, troubleshooting duplicated the problem. Elevator servo (p/n 4006719914) was replaced with serviceable unit.

After flying south through the Cajon Pass at 6500 feet msl, the airplane turned west and encountered what the commercial pilot presumed was leeside turbulence from the mountain range. She turned back south to find smoother air but the turbulence became more severe and the airplane began to descend rapidly. As the airline transport pilot struggled to change frequencies in the turbulence, the airplane descended to 2000 feet msl (about 500 feet agl). The commercial pilot applied full power but the engine did not respond. After the airline transport pilot enrichened the mixture and applied carburetor heat, the engine momentarily regained power. At about 2300 feet msl, the engine again lost power, and the ATP decided to land on the westbound lanes of a freeway. As he attempted to avoid a vehicle, the airplane landed hard.
