It was a dark and stormy day…seriously. Family issues required me to get to Clark Regional Airport (KJVY) in Jeffersonville, Ind. But the prognoses for the route from Augusta Municipal Airport (3AU) outside of Wichita, Kan., predicted lines of storms scattered across the 600-odd miles.

As the oft-paraphrased aphorism goes, all is well when the ties that bind us are stronger than the stresses that can separate us. The same goes for parking an aircraft. When we properly secure it after a flight, its reasonable to expect itll be there when we return. Once we release the ties that bind it, our aircraft will again provide us with reliable transportation. Most of the time, that is how it works. Other times, just a little inattention and improper securing of the aircraft-or improperly reversing the process during the preflight inspection-can and does lead to accidents.

Last December 24th, a Cessna 340 crashed at Bartow, Fla., during an attempted predawn, IMC departure. All five aboard the airplane died. We dont know yet what factors, if any, beside the weather may have contributed to this Christmas Eve tragedy. Regardless, the circumstances should remind us of the extra planning and skill needed for a departure into low IMC, day or night-even if everything is going right.

For the last few years, my home airport has been a private, paved and lighted strip in a rural area. The pilot-controlled lighting is non-standard, however. For one, the systems intensity is relatively weak. For another, there seem to be fewer runway lights than at most other airports Ive used. And the light fixtures themselves seem located farther from the pavement than Im accustomed. Often, there are few other ground lights in the area to help provide perspective at night. The runway does not have a rotating beacon, only a dimly lit windsock that may or may not tell the truth. There are few obstructions in the area above a couple of hundred feet, although theres a tall tower about five miles north.

The student pilot was doing an engine run prior to flight. Was unable on the first try to complete the magneto check as the key would not turn from the both position to the left/right/off position. After shutdown, the student was able to select off on the switch. The switch that was installed (p/n 103572101) included a push-to-start function. Found the switch sticking internally and replaced it with a new push-to-start switch.

About 1 hours into the return flight, I noticed I was switching fuel tanks more frequently than normal. The headwind I now had was payback for the tailwind on my arrival flight. From 12,000 feet msl down to 4000, the headwind was here to stay. I spent several minutes deciding if I had enough fuel. After going back and forth, I decided to play it safe and admit I didnt plan appropriately for the headwind. I located my new destination which was just 10 miles ahead. A sigh of relief came over me as I chose the safer option, stopping to refuel.

Almost from the beginning of our training, pilots are taught how to react to an engine failure. Before that, though, were also taught how to conduct a preflight inspection to ensure the engine (and the rest of the aircraft) is ready for what we are planning. Thats as it should be, since mechanical failures are a major component of overall accident causes, right after the pilot making a mistake. The good news is that the typical piston engine in a personal aircraft is much more reliable than it was a few years ago. The bad news is those reliability improvements often result in pilots giving little thought to piston engine aircraft reliability because failures have become so rare.

First my condolences and prayers go out to the entire Halladay family; his was a tragic loss.I commend Mr. Wright on his emphasizing risk management awareness, not only regarding the A5 but similar general aviation safety issues. Unlike many light sport aircraft that I am familiar with, the A5s inherent engineering design and safety features are second to none.
