ON-CONDITION TASK—A scheduled inspection to determine that equipment is and will remain in satisfactory condition until the next scheduled inspection. ON-EQUIPMENT WORK—For the purpose of MDR, it includes those maintenance actions accomplished on complete end items; for example, aircraft, drones, SE, and removed engines. OPC—Optimum Performance Capable—The material condition of an aircraft that can perform all assigned missions with all equipment operational. OPC Hours = MC Hours - (FMC Hours + PMC Hours). OPER—Operations (message). OPERABLE EQUIPMENT—Equipment which, from its most recent performance history and a cursory electrical and physical examination, displays an indication of satisfactory performance for all of its functions. OPERATING AIRCRAFT—An aircraft filling an authorized operating allowance. An aircraft reported in any of the A-status codes is in an operating status. Operating status aircraft are always in the reporting and physical custody of the operating unit to which assigned. An aircraft that moves to a rework facility for purposes of rework will leave operating status although it may remain in the reporting custody of the operating unit. Operating aircraft are in material condition reporting status. OPERATING COMMAND—A controlling custodian of naval aircraft, except COMNAV- AIRSYSCOM FS. Also called air or major operating command. OPNAV—Office of the Chief of Naval Operations. OPSERMOS—Operating Service Months. OPTAR—Operating Target (funding)—Annual funds (obligational authority) issued by TYCOMs, to units of the operating forces under their command, from one of their budgets. ORG CODE—Organization Code—A structured three-character alphanumeric code that identifies activities within a major command. ORGANIZATIONAL EQUIPMENT—Referring to method of use, signifies that equipment, other than individual equipment, used in furtherance of the common mission of an organization or unit. OSI—Operational Support Inventory. OSL—Operating Service Life. OSM—Operating Service Month—One monthly increment of operating service life (OPNAVINST 5442.2). OSP—Operating Service Period. OUT MCRS—Out Material Condition Reporting Status—The term (inventory codes 1 through 4) means that an aircraft is in the inventory reporting system but does not require SCIR documentation. An aircraft is placed OUT MCRS for depot-level maintenance. OVERHAUL—The process of disassembly sufficient to inspect all the operating components and the basic end article. It includes the repair, replacement, or servicing as necessary, followed by the reassembly and bench check or flight test. Upon completion of the overhaul process, the component or end article will be capable of performing its intended service life or service tour. P&E—Planner and Estimator. PACE—Paint and Corrosion Evaluation—An on-condition inspection developed to address special requirements of F/A-18 series aircraft, occurs at the end of a set operational service period, within a 9-month window. Details of program administration are in OPNAVINST 3110.11. Evaluation specifics are in a Local Engineering Specification from NAVAVNDEPOT North Island. The evaluation is performed by D-level P&E personnel and is requested via normal procedures for P&E services. The results of PACE determine the requirement for induction into the Modification, Corrosion and Paint Program, which is done by D-level artisans. Documentation required of the aircraft custodian is equivalent to aircraft administered by ASPA. PARTS KIT—Supporting items and material for the maintenance, repair, and rework of selected aeronautical repairable end items procured, stocked, requisitioned, accounted for, and used on a kit basis as one line item. Parts kits should not be confused with the kits issued to perform a onetime modification of an item or with interim fleet maintenance support kits. PARTS KIT CODES—Codes assigned to parts kits and items therein, for the maintenance, repair, and rework of selected, repairable end items. AI-19
