From an FAA press release about the alleged violations:
An FAA review of the airline's electronic record-keeping system for tracking crew duty and rest time revealed that Gulfstream International did not accurately input the proper data from its manually generated hard-copy aircraft logbook records into the electronic system. The discrepancies resulted in scheduling crew members in excess of daily and weekly flight time limitations.Gulfstream International Airlines has 30 days from the receipt of the civil penalty letter to respond to the FAA.
During a June 2008 inspection, the FAA determined that the airline had installed unapproved automotive air conditioner compressors on its aircraft between September 2006 and May 2008. Following the FAA inspection, the airline grounded all of the affected aircraft and replaced the units with approved aircraft air conditioner compressors.
In the course of a July 2008 inspection of Gulfstream International avionics and component shops in Fort Lauderdale, the FAA discovered that the airline had installed improperly maintained vent blowers on six planes between January 2008 and June 2008. Following that inspection, the airline replaced the blowers with properly maintained units.
