## Discrepancy

NOSE GEAR STRUT SEAL BLEW. NOSE GEAR DOORS WOULD NOT CLOSE DURING GEAR RETRACTION. EXTENDED LANDING GEAR FOR LANDING AND HAD TO MANUALLY ENGAGE/ARM NOSE STEERING. NOSE WHEEL STEERING FAILED DURING LANDING ROLL.  CORRECTIVE ACTION WAS TO REPACK THE STRUT, SERVICE AND REPLACE THE NOSE WHEEL ASSEMBLY.  NOTE: THE MECHANIC THAT COMPLETED THE REPAIR STATED THAT THIS IS A FAIRLY COMMON OCCURRENCE ON THE LEAR 60 AIRCRAFT, THAT HIS GROUP SEES THIS 6-7X PER YEAR.  THE REPAIR WAS COMPLETED BY SPECTRA JET, INC.
