Three aeromedical helicopter accidents claimed three lives in just 12 days in August and September, representing a cluster of successively serious mishaps in what otherwise had been a fairly uneventful year in terms of EMS safety.

Piper is working on boosting the max takeoff weight for its Meridian turboprop single to create a 15-percent increase in useful load. By the end of the year, Piper said it will receive certification of aerodynamic and structural changes to its Meridian that will allow a 242-lb increase in mtow from 4,850 lb to 5,092 lb.

Economical, practical, environmentally friendly supersonic flight is the next big thing in commercial aviation. Or is it? From where aeronautical technology stands today, practical supersonic flight (and by “practical,” we do not mean the Anglo-French Concorde, which generates noise and atmospheric pollution levels that preclude all but the smallest volumes of operation) is far off.

Aero Toy Store has been appointed the factory authorized representative of Aerion for the sale of the company’s supersonic business jet. The agreement allows the initial sale of 12 of the new jets, which will cruise at speeds up to Mach 1.6 at altitudes of up to 51,000 feet. It has a range of 4,000 nm.

As corporate pilots Tom and Pam Clements climbed the stone steps at the forbidding Angkor Wat temples in Cambodia, it seemed incredible that they were being paid to go on this “vacation.” Though the Clements had paid the incremental cost of accompanying their passengers on various sightseeing tours, the husband and wife team had still turned a small profit flying their passengers on a three-month, eastbound journey from Scottsdale, Ariz., near

Design changes to resolve a manufacturing problem with the wing leading-edge anti-ice system of the Premier I were under way at press time. It was possible the modification would be installed on all affected aircraft before the June 29 compliance date of an AD that prohibits the new jet from flying into known icing until it is modified.

Whenever a manufacturer develops a new airplane, engineers have the opportunity to incorporate new technology into the design. With the large-cabin Columbus, Cessna engineers didn’t opt for a composite airframe or an all-electric systems architecture, but they have chosen an innovative approach to fly-by-wire flight controls.

The prospect of designing a supersonic business jet that meets market requirements and environmental noise constraints at a price that will attract buyers remains compelling, and research continues. The Department of Aerospace Engineering at the University of Illinois at Urbana-Champaign recently signed an agreement to research SSBJ sonic boom mitigation with Rolls-Royce Deutschland and Gulfstream Aerospace.

Piper PA-46 Meridian, San Antonio, Jan. 18, 2008–The instrument-rated pilot of the Meridian was killed and the aircraft destroyed when the pilot lost control on an instrument approach in IMC to San Antonio International Airport. The pilot reported that he was having trouble performing a “coupled” approach and that he was trying to “get control” of the airplane before the flight disappeared from radar.
