Aerion chief technology officer and director Dr. Richard Tracy told AIN today at EBACE that his company is “revisiting” the powerplant for its proposed $80 million supersonic business jet (SSBJ), citing the previously selected Pratt & Whitney JT8D-219’s inability to meet upcoming Stage 5 noise requirements.

Operators of Gulfstreams based or traveling in Europe will benefit from augmented support capability. Gulfstream has moved more parts into the region, bringing the total value to $125 million. Most of Gulfstream’s Europe-based parts and materials–nearly $80 million worth–are located in Madrid at Corjet Maintenance’s warehouse at Barajas Airport. Gulfstream’s Luton and Madrid facilities can ship parts anywhere in Europe or the Middle East within 24 hours and offer a 24-hour call-in number for customers who need parts support.
