PiperJet Begins Taxi Trials

High Speed Ground Tests Imminent

As we enter the home stretch towards AirVenture 2008, these are busy times for a pair of single-engine jet development programs... and the question is, which will fly first? Hot on the heels of news Cirrus is now ground-testing its "the-jet" concept, now comes word that the first time in Piper Aircraft's 71-year history, the sound of a turbofan-powered Piper airplane was heard when the PiperJet Proof of Concept's engine was started and tested on June 19, 2008.

Density Altitude A Factor In Pair Of Weekend Accidents?

Hot & High A Common Factor In NM, NV Fatals

With the hotter temperatures of summer comes a potential, hidden danger for aircraft operations... density altitude, in which air becomes less dense as temperatures climb. And though its too early to determine for certain, the combination of heavy loads and high D.A. may have played a role in a pair of weekend crashes that claimed nine lives between them.
