Narrative:
A Gulfstream G150, N373ML, was substantially damaged when it was involved in an accident at the Fernando Luis Ribas Dominicci Airport (TJIG), San Juan, Puerto Rico. The two pilots and two passengers were not injured.

According to the pilot, the instrument approach to runway 09 was "stabilized, on glide path, and on speed." The landing reference speed (Vref) was 122 knots and touchdown occurred at the 1,000 ft markers. The thrust reversers were deployed until 70 knots. The pilot then noticed standing water on the runway, and as the airplane encountered the standing water, it yawed to the right and departed the runway. The airplane impacted a chain-link fence and sustained substantial damage to the right wing spar. The pilot further reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Weather observations at TJIG were reported only when the air traffic control tower was open (0700 to 1900), and there were no automated weather observation stations at the airport. The last available observation occurred at 1745, which indicated that rain showers were in the vicinity of the airport to the southwest and northwest. Automated weather observations reported at the San Juan Luis Marin International Airport (TJSJ), located about 5 miles to the east of TJIG, included rain showers at that airport or in the vicinity for the 4 hours preceding the accident. At 2056, the conditions reported at TJSJ included heavy rain showers and mist.

Probable Cause:

Probable Cause: "The pilot’s loss of control during landing on a wet runway after encountering standing water."
