Sioux Falls, SD (September 5, 2012) —Aerostar International, Inc. has selected a group of companies to carry on the supply of repair and replacement parts for Raven/Aerostar hot air balloons. These companies will take over the supply and distribution of parts in early 2013. Aerostar recognizes that the owners of Raven/Aerostar hot air balloons have made a large investment in their aircrafts and the necessity for parts to be available well into the future.

The following companies will be future suppliers:

Parts Authority, a wholly owned subsidiary of Balloonacy Ltd. located in Fayetteville, GA owned by David Sullivan.

They will also be supplying other fabrics needed to support Aerostar balloons including lightweight soar-coat fabrics and fire retardant Nomex fabrics.

These companies were selected based on their long standing reputations and commitment to the sport of hot air ballooning. These companies share our dedication to the quality of our products and the safety of our owners and their passengers.

Raven/Aerostar is proud to be the originator of the modern day hot air balloon. Our commitment has always been to provide a high quality, safe and reliable product to our customers.
