An elderly man and his son from The Woodlands died in an experimental plane crash in La Porte on Sunday, according to police.

John Stewart Boyd, 93, and Gary Stewart Boyd, 64, were confirmed by the Harris County Medical Examiner's Office as the occupants of the plane that crashed at 9 a.m. July 15.

The Experimental Kolb Twinstar III was approaching the north side of the La Porte Municipal Airport when it crashed about 300 yards from the end of the runway, the Federal Aviation Administration previously told

Sgt. Bennie Boles of the La Porte Police Department said the plane went into a pipeline easement, causing no damage to ground structures or injuries to people other than the two occupants.

The La Porte Police Department, Texas Department of Public Safety, and FAA are supporting the National Transportation Safety Board as that agency investigates.

Eric Weiss, a spokesman for the National Transportation Safety Board, said the agency completed an on-scene investigation on Monday. Investigators are now collecting evidence before issuing a factual report for the accident. A final report determining the probable cause of the accident usually takes between 12 and 18 months.

"Our investigator completed his on-scene investigation and a preliminary report should be out by the end of the week," Weiss said.

Mark Bertram, who lives in La Porte, said he saw the plane Sunday when he rode his motorcycle past the airport just a few minutes after the crash.

"The tail was straight up in the air," he said. "The front was smashed flat like a pancake."

Now marketed as the Kolb Mark III, the plane involved in the crash is a kit-built light sport aircraft, designed for speed, according to the Kolb Aircraft website. "Although Kolb aircraft are easy to fly and have gentle flight characteristics, they are also high performance aircraft," the website states.

If the National Transportation Safety Board investigation finds a safety issue with the aircraft, the agency would issue safety alerts or urgent safety recommendations about that particular model.

LA PORTE, Texas (KTRK) -- Two people are dead after an aircraft crashed near the La Porte airport, officials said.

According to the Federal Aviation Administration, the incident occurred shortly before 10 a.m. about 300 yards from the runway.

The small experimental aircraft attempting to return to the runway came down in a field near the 11000 block of North H Street.

The FAA described the plane as an Experimental Kolb Twinstar II, telling Eyewitness News it was built by a private citizen and not by a certified manufacturer.

"Thousands of aircraft owners prefer to build their own planes from kits or plans," said Lynn Lunsford, a spokesperson for the Federal Aviation Administration.

Jill Mancha, a neighbor who lives nearby, said she was in her home when she heard the plane sputtering in the air.

"As I opened the front door, the plane hit the ground with a thud. Didn't sound like the engine was running," Mancha said.

She tells Eyewitness News she grabbed her phone and ran to the wreckage while calling 911.

When she got to the plane she says it was clear both the pilot and passenger were deceased.

"I prayed over them. I do want the families to know that I prayed and I felt the peace of God around their plane and those men inside there," she said.

The National Transportation Safety Board is sending investigators to the crash site, and the Federal Aviation Administration will be assisting with the investigation. The names of the victims have not been released.
