A United Airlines pilot was caught in shocking video attacking a parking arm at Denver International Airport with an ax — later telling authorities he “just hit his breaking point.”

Kenneth Henderson Jones, 63, is seen in Colorado walking toward the exit gate of an employee parking lot clutching the full-size ax on Aug. 2, according to CBS News Colorado, which obtained the footage.

The unhinged pilot then whacks the lowered arm 23 times until it falls off as a car is seen entering the lot to his left.

The video then cuts to an airport worker trying to wrest the ax from Jones, who holds on to it before another employee arrives and helps his colleague disarm him. Airport police finally arrested him nearby.

Airport officials described the wild incident as a “physical struggle” with no injuries, according to the outlet.

Jones was charged with misdemeanor criminal mischief.

He told Adams County sheriff’s deputies that “he just hit his breaking point,” the CBS station said.

He also said he was trying to leave but he estimated there were six vehicles in line at each of the three gates — and “was trying to get rid of issues for everyone waiting.”

Airport administrators reportedly said there have been issues at the lot with employees who don’t have the proper permits.  

Airline spokesman Russel Carlton told CBS Colorado that Jones “was removed from the schedule and is on leave while United conducts an internal investigation.”

The pilot — who is rated to fly Boeing 767s and 757s, according to FAA records — did not respond to the outlet’s requests for comment.

He is scheduled to appear in Adams County Court on Sept. 25.
