Owning an airplane requires a certain suspension of the economic rules that govern normal people, but on the whole, the airplane industry operates under an even more perverse logic: As sales soften, it raises unit prices, perhaps chasing away those buyers on the margins who might have been toying with pulling the trigger to buy […]

Years ago in a sleepy college aircraft economics class, welearned the pecking order of items to consider when acquiringan aircraft. The short list included the usual items of damage history,engine time, avionics, operating costs and a variety of other factorsmaking obvious sense. But one aspect of aircraft acquisition wewerent taught is an issue thats gained […]

For years, there was only two choices for a retrofit multi-function GPS navigator-either Garmin’s GNS430 or GNS530-or the current GTN650 and GTN750. Bendix King offered the KLN94 standalone GPS, but it wasn’t an all-in-one WAAS navigator with an open architecture. It also lacked a comm and nav radio and it didn’t have any multi function […]

Piper Aircraft has announced the successful completion of a 2100-mile round-trip flight in a Piper Archer flying with 93 octane unleaded automobile gasoline provided by Airworthy AutoGas LLC. The company says the flight was conducted as a demonstration and test of Airworthy’s specially formulated auto gas. It is a continuation of previous joint testing that […]

The Citabria is a nice, modern taildragger and one for which parts are readily available, so it’s a perfect refurb project. John Myers of Sequim, Washington, sent us this report on his project: This was a project completed at an airpark home, in a garage-hangar.I had thehelp from a youngA&P and neighbor A/I for inspections.We […]

Embry-Riddle Aeronautical Universitys testing of GAMIs G100UL unleaded fuel looks promising, the school told AVweb last week, and it says it sees no reason why the fuel cant be a drop-in replacement for 100LL. With two major flight training campuses, ERAU wants an unleaded replacement for avgas sooner rather than later and has been testing […]

ECi is using a new web page to highlight resistance to the FAA’s proposed Airworthiness Directive targeting TITAN brand 520/550 series cylinders produced between 2002 and 2009 that may cost $83 million in compliance-associated costs, but the resistance isn’t universal. The FAA wants to require initial and repetitive inspections of the cylinders, plus full replacements […]

It wasnt 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 […]

Ive always figured there were two theories of aircraft ownership: the magic carpet school and the ticking time bomb philosophy. The former gets tangled up in the romance and passion of airplanes as a means of justifying virtually any aircraft-related expense, no matter how irrational or how large. The time bomb view, which is what […]

Last weeks massive proposed airworthiness directive aimed at thousands of Engine Components International cylinder assemblies is drawing mixed reactions from engine overhaul shops, according to an AVweb canvass of shops this week. While some say the proposed AD is a kneejerk over reaction, at least one shop told AVweb that the AD is justified, based […]
