Maintenance

For many pilots, the first realization that the bellies of their airplanes are becoming hazardous waste sites is when ATC advises that their transponders are intermittent. Investigation reveals a layer of goo on the belly antennas, doing its best to block the signal. Frequently cleaning the by-products of engine operation—oil, grease, soot and other delicacies—off […]

Pilots decide to buy their own airplane for a variety of reasons. It could be a business decision, helping ensure coverage of a relatively wide sales area, or perhaps an aerial photography business. Specialized flight training—like acro, or a quicky instrument rating—also can be a reason. Recreation or personal transportation is yet another. One of […]

One of the centerpieces of any aircraft refurb is upgrading the interior. It can be as basic as recovering the seats, but usually involves a complete redo of the headliner, side panels, carpet and upholstery. As the insulation is often stripped out and replaced as well, it’s a good time to install soundproofing. One thing […]

As a long-time IA and A & P mechanic and pilot I look at airplanes with a somewhat different eye than pilots. My purpose, whether it’s actually inspecting an aircraft, flying one or writing about my experiences, is safety. Most certificated aircraft owners should know what the meaning of airworthy is and that there are […]

Still the only production four-seat or side-by-side, conventional gear airplanes being built in the U.S., Maules have been attracting owners who march to a slightly different beat for over 50 years. In general, the Maule airplanes are easy and forgiving to fly when in the air, yet not so much on the ground—the runway loss […]

Engine overhauls give even the most experienced aircraft owners a case of the willies. Beyond the “it’s going to be really expensive,” there are numerous issues to face and decisions to make—choosing a shop; deciding on the type of overhaul, or a factory reman, and what to do about the engine accessories are some that […]

It wasn’t long ago that an entry-level, two-axis autopilot was priced around 10 grand—including installation. Today, that price is double. Add some options and the bottom line could soar toward $30,000. These big proposals have many owners repairing older autopilots. But as service parts for older systems become obsolete, repair costs are high, downtime is […]

Is nosewheel shimmy bugging you? It’s a continuing problem for many aircraft owners. With the following, we offer suggestions to minimize the effects of, or even solve this annoying problem. In order to correct nose wheel shimmy problems we must understand what causes the nose wheel to shimmy in the first place. Without getting too […]

The turbocharger is a useful part of a pilot’s toolbag. When flying an airplane with one installed, it can increase our rate of climb, boost our groundspeed and lift us above a lot of the weather. It also can be used to pressurize the airplane’s cabin, allowing us to enjoy a shirtsleeve environment in the […]

Some insist it began production as the world’s largest flying sweet potato and evolved into Snoopy crouching as he waited for his supper. The original PA-23, the Apache, seemed almost round and had such modest powerplants that single-engine operation could be hazardous—just as with other twins with small engines. The last versions, the Aztec series, […]
