For as bad as the aviation boom-bust cycle is for companies that make airplanes, it’s just as bad for the people who buy them. The euphoria that goes with pocketing the keys to a brand new airplane has to be tempered by the reality that the company that built it maybe teetering toward bankruptcy.

Is there a better business plan, one that envisions modest production and flexible size and that can survive the test of the worst economic downturns? There are at least a couple of examples that suggest this can work. The family-owned Maule Air is one, shipping 30 or 40 airplanes a year to Cessna’s 500, but lately a lot less. American Champion, which counts as the most enduring rag-and-tube manufacturer, is another, building as many as 90 airplanes a year but as few as a third of that number.
