Synopsis
A Maintenance Control Manager and a Maintenance Controller report about a company A319 that was Returned to Service (RTS) after an In-Flight Shutdown (IFSD) of the #2 engine without accomplishing a required Windmill Inspection.
Narrative
An A319 aircraft returned with #2 engine shut down; due to oil quantity drop in flight. It was determined the oil quantity transmitter; or wiring; was at fault. Checked engine for leaks; none found. Two quarts of oil added. Crew reported oil pressure and temperature were good prior to engine shutdown. Ran engine and checked for leaks; none found. Placed #2 engine oil quantity indicator on MEL. No Inspection requirements found in Chapter Five.Following day at work; found there is a windmilling inspection [requirement] in Maintenance Manual (MM) 72-00-00-200; which was complied with at ZZZs Routine Overnight Maintenance (RON).I had left work and Engineering discovered there was an Inspection in MM 72-00-00-200 which was not Complied With (C/W); but was later accomplished at RON in ZZZ; after flight from ZZZZ. I was not aware that MM 72-00-00-200 existed. Aircraft arrived safely for RON where Inspection per MM 72-00-00-200-021 was accomplished. An alert bulletin would be good [to inform Maintenance Control personnel].
Second reporter narrative
Flight Returned to Field (RETF); engine #2 Oil Quantity Indication erratic; pilot shut-down engine. On ground; working with Maintenance Control; Foreign Contract Maintenance provider determined oil quantity was normal; oil pressure was normal during in-flight event. Engine runs on ground normal. Oil Quantity transmitter part known to have failed previously; history on other aircraft.Maintenance Control placed oil quantity indicator on MEL. Powerplant Engineering contacted Maintenance Control and requested Flight Data Recorder (FDR) download and read; Maintenance Control Supervisors researched and determined no further inspections required. Engine OK'd for Return to Service (RTS). Aircraft departure it was later determined that a windmill inspection after an In-Flight Shutdown (IFSD) was required. An Engineering Special Inspection was written and Chapter 05 Inspection was completed at ZZZs Routine Overnight Maintenance (RON). New engine unfamiliarity.
