## Discrepancy

AC WAS IN THE HANGAR FOR 50 HOUR INSPECTION. STROBE LIGHTS WERE TURNED ON AND AN EXPLOSION DAMAGED THE LEFT WING TIP TANK.  FWD FAIRING WAS BLOWN APART BY AN EXPLOSION.  FOUND THE FWD TANK ACCESS PANEL SPOT WELDS FOR THE NAV/STROBE LIGHT BRACKETS WERE CRACKED, ALLOWING GAS FUMES TO COLLECT IN THE NOSE CONE AND CAUSE THE EXPLOSION.
