Authorities search for cause in AZ plane crash that killed 4, registered owner identified

EAGAR, AZ - A small plane that crashed into an eastern Arizona high school Friday, killing all four people on board, was registered to a Florida man, according to reports.

Federal records show the single-engine Piper PA 32R 300 was registered to Jeffery John Ulrich of Wesley Chapel, Florida.

Investigators on Sunday were able to find all major structural components of the single-engine aircraft. The wreckage is being transported to Phoenix, where investigators will continue their work.

Authorities have yet to identify the four people killed in the crash or determine their gender or age, and have not confirmed if registered owner Ulrich was flying the plane when it crashed Friday.

There were no reports of injuries on the ground in the small town of Eagar.

NTSB investigators are continuing to examine flight paths and weather conditions at the time of the crash.

National Transportation Safety Board investigator Joshua Cawthra says it will be a complex job of determining what led to the crash because of the amount of debris involved and the resulting fire damage.

The plane had just taken off from the nearby Springerville airport when the crash happened. It was headed to the Grand Canyon.
