What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On March 20, 1999, at approximately 9:12 MST a corporate Gulfstream, GA-690-D was enroute to mccook, NE when moderate smoke entered the cockpit. The crew employed emergency procedures and diverted the flight into Farmington, NM (fmn). A maintenance inspection was conducted at the FBO by qualified mechanics revealing a seal in the air cycle machine had failed leaking oil into the system. There were no injuries. The crew arranged transportation back to sturgeon bay, WI for the passengers on a chartered aircraft. No minimum equipment list exist under which the aircraft could be operated in its un-airworthy status. However the crew proceeded to fly the aircraft home to sturgeon bay, WI, without securing an authorization under a special airworthiness certificate.
