Narrative:
Air carrier flight abc, ship xyz, departed WWW. Crew reported nose gear would not retract. Maintenance control advised crew to continue to ZZZ 'gear down.' myself and air carrier technician JJJJ dispatched to ZZZ. Found nose strut 2 pints over svced with strut fluid. We correctly svced strut per MD88 maintenance manual. The nose was jacked and nose gear was swung several times. At this time it was noted that nose gear down lock link pivot bolt had very close clearance to wheel well structure when gear retracted. Found per ipc, a washer under bolt head missing. Replaced washer. Found clearance satisfactory for gear operations clearance but not adequate for normal service. Per XXX maintenance coordinator the aircraft was to make a maintenance ferry flight to XXX for nose gear maintenance. I made a separate logbook entry, per XXX maintenance coordinator, with the corrective action statement that I had swung the nose gear, and that it operated normal and indicated normal so that aircraft could make the ferry flight 'with the landing gear retracted.' he advised me that he had contacted XXX line maintenance with my findings and they would correct the discrepancy. There were 4 entries in logbook when aircraft departed ZZZ. 1) the original flight crew squawk on gear not retracting. This was an open log item. 2) the install and removal of landing gear safety pins for gear maintenance. 3) an entry that the strut was svced, washer replaced, and gear swing. 4) the entry for ferry flight permit. After my regular day off, I checked the log records for this aircraft. It was noted that XXX performed no maintenance on the original discrepancy. The signoff was 'see item 3 for corrective action.' item 3 was not the corrective action for this discrepancy. I feel that there was a breakdown in communications between XXX maintenance coordination and XXX line maintenance or XXX line maintenance did not address the original discrepancy.

Title: AN MD88 WAS DISPATCHED WITH AN INTERIM REPAIR DONE TO THE NOSE LNDG GEAR FOR CORRECTIVE ACTION AT A MAINT FACILITY BUT THE CORRECTIVE ACTION WAS NOT ACCOMPLISHED.
Narrative: ACR FLT ABC, SHIP XYZ, DEPARTED WWW. CREW RPTED NOSE GEAR WOULD NOT RETRACT. MAINT CTL ADVISED CREW TO CONTINUE TO ZZZ 'GEAR DOWN.' MYSELF AND ACR TECHNICIAN JJJJ DISPATCHED TO ZZZ. FOUND NOSE STRUT 2 PINTS OVER SVCED WITH STRUT FLUID. WE CORRECTLY SVCED STRUT PER MD88 MAINT MANUAL. THE NOSE WAS JACKED AND NOSE GEAR WAS SWUNG SEVERAL TIMES. AT THIS TIME IT WAS NOTED THAT NOSE GEAR DOWN LOCK LINK PIVOT BOLT HAD VERY CLOSE CLRNC TO WHEEL WELL STRUCTURE WHEN GEAR RETRACTED. FOUND PER IPC, A WASHER UNDER BOLT HEAD MISSING. REPLACED WASHER. FOUND CLRNC SATISFACTORY FOR GEAR OPS CLRNC BUT NOT ADEQUATE FOR NORMAL SVC. PER XXX MAINT COORDINATOR THE ACFT WAS TO MAKE A MAINT FERRY FLT TO XXX FOR NOSE GEAR MAINT. I MADE A SEPARATE LOGBOOK ENTRY, PER XXX MAINT COORDINATOR, WITH THE CORRECTIVE ACTION STATEMENT THAT I HAD SWUNG THE NOSE GEAR, AND THAT IT OPERATED NORMAL AND INDICATED NORMAL SO THAT ACFT COULD MAKE THE FERRY FLT 'WITH THE LNDG GEAR RETRACTED.' HE ADVISED ME THAT HE HAD CONTACTED XXX LINE MAINT WITH MY FINDINGS AND THEY WOULD CORRECT THE DISCREPANCY. THERE WERE 4 ENTRIES IN LOGBOOK WHEN ACFT DEPARTED ZZZ. 1) THE ORIGINAL FLC SQUAWK ON GEAR NOT RETRACTING. THIS WAS AN OPEN LOG ITEM. 2) THE INSTALL AND REMOVAL OF LNDG GEAR SAFETY PINS FOR GEAR MAINT. 3) AN ENTRY THAT THE STRUT WAS SVCED, WASHER REPLACED, AND GEAR SWING. 4) THE ENTRY FOR FERRY FLT PERMIT. AFTER MY REGULAR DAY OFF, I CHKED THE LOG RECORDS FOR THIS ACFT. IT WAS NOTED THAT XXX PERFORMED NO MAINT ON THE ORIGINAL DISCREPANCY. THE SIGNOFF WAS 'SEE ITEM 3 FOR CORRECTIVE ACTION.' ITEM 3 WAS NOT THE CORRECTIVE ACTION FOR THIS DISCREPANCY. I FEEL THAT THERE WAS A BREAKDOWN IN COMS BTWN XXX MAINT COORD AND XXX LINE MAINT OR XXX LINE MAINT DID NOT ADDRESS THE ORIGINAL DISCREPANCY.
