What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On may 16, 2018, approximately 1000 central standard time, the st. louis flight standards district office received notification that a Israel Ia-Astra aircraft, cgrjp, serial number 080 declared an emergency and diverted to st. louis lambert international airport (stl) as a precaution. The aircraft is a foreign registered aircraft and is operated by pattison airways located in vancouver, Canada. According to the crew the aircraft experienced a heavy amount of rain with the main entry door open prior to departure from hartsfield-jackson atlanta international airport (atl). During cruise from atlanta to vancouver, the aircrew experienced unusual loads on the ailerons. Aircrew reported that flight control operation was normal after decreasing altitude. A Gulfstream representative examined the aircraft, determined that water intrusion had possibly occurred in the flight control rod/bell crank area underneath the entry floor area, and as a result froze while in a cold-soaked condition during cruise. Maintenance was performed in order to remove the water and any debris in the area of the flight control and bell crank area. Gulfstream technicians witnessed some debris and standing water under floor panels 88, 89, 90 and 92 of the main entry door area. Some of this debris was blocking drain paths preventing the water from draining. Aircraft was determined by Gulfstream technicians to be airworthy however, Gulfstream requested that the operator also perform inspections of the aileron artificial feel unit for possible moisture intrusion which the operator declined and deferred to another time. It was also recommended that the operator perform inspections of the aileron controls, aileron servo actuator, aileron linear ball bearing, fuselage drains and to lubricate the aileron artificial feel spring unit. Compliance of these tasks can not be confirmed as the operator is no longer registered and reporting via Gulfstream?s computerized maintenance program (cmp). The operator elected to return the aircraft to service after satisfactory operational checks of the aileron control. Aircraft departed and continued to its destination in vancouver. The aircraft landed without incident.
