Accident Probes

Thank you for printing in Augusts magazine the short letter I wrote, highlighting an issue I encountered just south of the Albany, N.Y., Class C airspace-a Cub showing an ADS-B altitude of 500 feet below sea level. (By the way, I passed the same Cub today at very close range. This time he wasnt showing up at all on ADS-B). In your response, you asked readers to report other anomalies, so heres one from a week or so ago.

Toward the back of the magazine youre holding in your hand, in our Quick Turns department, theres a news item about the FAA formally transitioning to the ICAO-standard/international flight plan form for all domestic non-military operations. If youve been paying attention over the last few years, as we have, youll be happy to know a process that has seen several earlier deadlines come and go seems to have finally staggered across the finish line. As of August 27, the international flight plan form is the law of the land, so to speak.

During the landing roll, three deer ran from right to left across the runway. The pilot felt a hard strike on the inboard section of the right wing, observed a deer roll over the right wing and felt a sensation of the right landing gear running over a second deer. Although the airplane sustained substantial damage to its right wing, the pilot was able to maintain control and taxied to the ramp without further incident. The pilot and passenger had to egress through the rear baggage door due to damage to the cabin door.

We all know how to fly a missed approach. We probably did a handful of them on our instrument checkrides, and when were out practicing approaches, even in a sim, we most often go missed. We may not be flying a full missed approach procedure as published, but we still have to reconfigure the airplane and climb away. When were practicing, we know how the approach will terminate: by going around at the missed approach point. Its what we expect when practicing.

When we approached the centerline, she nudged me on the shoulder. I rolled the plane to where I thought the runway centerline was. At this point we were totally in the soup, and I was flying by training instinct. I saw the ADF needle swing to the rear, indicating wed passed the outer marker, and I initiated a standard approach descent of 500 fpm, as I figured that would keep us close to the glideslope.

Sitting around and talking with pilot friends, you hear nonstop talk about aircraft and equipment. Eventually, someone always brings up ATC in conversation. Pilots argue among themselves more intensely than Socrates debating Plato. One question that new and even veteran pilots bring up is why, when they file an IFR flight plan, that their clearance is usually never as filed but includes a route change of some sort.

In the decade-plus since the coming ADS-B mandate became a thing for U.S. aviation, those whose operations will be affected have fallen mainly into two camps: early adopters and those who put it off as long as possible. In this binary world, I freely admit to being something of an early adopter. And despite some cool-and less expensive-new gear on the market, Im happy with my choice to equip with ADS-B in 2016. Its likely those who have taken a wait-and-see attitude also are happy.

The weight of the engine is only significant in that it is part of the center of gravity of the aircraft, which naturally lies aft of the main gear in a taildragger. Therein lies the problem, especially while landing. That center of gravity, without interference, will travel in a straight line when in motion, according to Newtons First law, which is often called inertia. It is imperative that we keep the airplane (longitudinal axis) tracking and aligned with that same straight line.

Everything we do in life carries risk. An undesired outcome often is influenced by factors we cant control-someone running a stop sign, for example, or a perfectly good engine deciding to fail. But many other risks of a specific activity can be anticipated. Its why we wear a helmet when riding a bicycle, or earn our instrument rating if we regularly fly an airplane beyond the traffic pattern. Serving as a pilot in command offers many ways to increase our risks, but it also brings opportunities to mitigate them.

After noting that five incidents of aircraft uncommanded roll events with the ATLAS activated have been reported to EASA and the FAA, the U.S. agency on May 24 issued an airworthiness directive (AD) grounding Cessna CitationJet 525, 525A and 525B models equipped with Tamarack active load alleviation system (ATLAS) winglets. The action is related to an EASA AD and is mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product.
