While approaching Denver runway 35L, the landing gear was lowered, but did not show three greens. The crew said that this had been a recurring problem with this particular airplane. The landing gear was cycled but this did not solve the problem as it had in the past. After consulting the emergency checklist, the crew felt confident that the landing gear was extended and locked because the hydraulic pressure gauge indicated 2,000 pounds. The airplane landed wheels up. Propeller blade fragments penetrated the fuselage and breached the pressure vessel.

Probable Cause:

PROBABLE CAUSE: "The failure of the landing gear system and the flight crew's failure to ascertain that the landing gear was down and locked. A contributing factor was the inadequate maintenance inspections performed by maintenance personnel."
