Yeah it's non-precision but in perfectly clear weather they should be able to land the airplane visually with no problems.
Mech failure notwithstanding, under no circumstance will the probable cause of the accident in the final NTSB report be stated as "the probable cause of this accident was the unavailability of the instrumental landing system..."
