Analysis

The owner/plt (PIC) was on a flt for night & instrument currency requirements. He was flying the acft from the left front seat while a commercial plt (cp) was occupying the rgt front seat. Drg an ILS rwy 26L final apch at Ontario, CA, the PIC & cp discussed a constant 'on glide slope' indication & elected to make a localizer only apch. The cp mistakenlyselected an incorrect apch plate & advised the PIC that the min dscnt alt (mda) was 1060'. The actual mda for the apch was 1240'. While they were discussing the alt, the acft dscndd & struck elec transmission lines at an elev of 992'. The acft became entangled in the lines & remained suspended for 4 hrs before the plts were rescued.
