## Discrepancy

CUSTOMER REPORTED THE LT MLG DOWNLOCK LIGHT DID NOT ILLUMINATE WHEN THE LANDING GEAR WAS EXTENDED.  AIRCRAFT LANDED WITHOUT INCIDENT.  INSPECTION REVEALED THE PN 41949-02 LANDING GEAR LOCK ROD ASSY WAS SEIZED DUE TO LACK OF LUBRICATION PREVENTING THE DOWNLOCK HOOK FROM FULLY ENGAGING.  SUBMITTER STATED THE MM CALLS FOR A 100-HOUR LUBE.  A MORE FREQUENT LUBRICATION MIGHT BE ADVISABLE IN WET/CORROSIVE ENVIRONMENTS.
