45th Anniversary of Air Medical Evacuation Services (AMES)

PHOENIX, Ariz., (May 26, 2014) - Civilian use of helicopters for emergency medical services (EMS) seems like a standard service today in the U.S. and many other countries.

PHOENIX, Ariz., (April 28, 2014) - Thirty eight years ago this month Allison (now Rolls-Royce) received certification for the 500 shaft horsepower 250-C28 engine.

The C28 engine soon developed with two additional versions. In 1978 the C28B was certified for the Bell 206L-1 LongRanger and the C28C for the MBB (now Airbus Helicopters) Bo 105L. The C28C is identical to the C28B, except without a particle separator.

We Were Hiring Helicopter Technicians In 1967 & We Still Are Today

PHOENIX, Ariz., (March 18, 2014) - Going through old newspaper articles recently we found one of our old job adverts from Saturday March 18, 1967 in the Arizona Republic newspaper.

The ad is pretty simple, stating “AIRCRAFT MECHANIC Must have FAA airframe & power plant rating, interested in learning helicopter overhaul & maintenance.”

There are some other interesting job ads on the same page including one for a Xerox Operator and another for a Computer Programmer with experience in COBOL.
