accomplished on complete end items; for example,
aircraft, drones, SE, and removed engines.
OPCOptimum Performance CapableThe material
condition of an aircraft that can perform all
assigned missions with all equipment operational.
OPC Hours = MC Hours - (FMC Hours + PMC
OPERABLE EQUIPMENTEquipment 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 AIRCRAFTAn 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
custodian of naval aircraft, except COMNAV-
AIRSYSCOM FS. Also called air or major
OPNAVOffice of the Chief of Naval Operations.

PACEPaint and Corrosion EvaluationAn
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.

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.
