Emergency crews are investigating after a Learjet 36 crash-landed into an embankment along the shoreline at Naval Air Station North Island on Friday, base officials said.
The hard landing happened about 1:15 p.m. at the end of runway 18 at Halsey Field Airport, which is on base, said spokesman Kevin Dixon.
According to FlightAware, the fixed-wing aircraft took off from the airport around 12:20 p.m., made a few figure eights over the ocean and came in for a landing less than an hour later.
The plane is owned by GH Equipment, according to Federal Aviation Administration records. Dixon said the plane was a Navy contractor plan, not a military aircraft.
The jet appeared to have sustained minor damage, and it is unclear if anyone was injured.
