Incident Overview
An aircraft conducting a flight for night and instrument currency requirements became entangled in electrical transmission lines at Ontario, California. The pilot in command (PIC) was occupying the left front seat, while a commercial pilot (CP) was seated in the right front seat. The incident occurred during an approach to Runway 26L.
Approach and Miscommunication
While executing an ILS final approach to Runway 26L, the PIC and CP discussed a constant 'on glide slope' indication. They decided to transition to a localizer-only approach. During this change, the CP mistakenly selected an incorrect approach plate and advised the PIC that the minimum descent altitude (MDA) was 1,060 feet. The actual MDA for the intended approach was 1,240 feet.
Descent and Impact
While discussing the altitude, the aircraft continued descending and struck electrical transmission lines at an elevation of 992 feet. The aircraft became entangled in the lines and remained suspended for approximately four hours before the pilots were rescued.
Aftermath
Both pilots were rescued after the aircraft had been suspended in the power lines for four hours. The source does not provide further details on the condition of the pilots or the aircraft damage.
