## Discrepancy

GEAR-UP LANDING ON ASPHALT RUNWAY.  NO INJURIES.  ALL LANDING GEAR DOORS OPENED, BUT GEAR FAILED TO EXTEND EITHER ELECTRICALLY OR MANUALLY.  FAILURE CAUSED BY RESIDUE BUILT-UP ON SHAFT OF SOLENOID PN 9881201-1 PREVENTING OPERATION OF MANIFOLD ON POWER PACK.  AFTER SOLENOID SHAFT CLEANED, LANDING GEAR EXTENDED BOTH ELECTRICALLY AND MANUALLY.  SUBMITTER SUGGESTS INSPECTING/CLEANING SOLENOID SHAFT AT 1,000-HOUR INTERVALS.
