DEFECT IDENTIFICATION AND CLASSIFICATION: Each JACE condition code and any
other noted defects have three possible defect classifications. After examining the defect, classify it
as either minor, major, or critical, depending on the severity of the defect. The defect classification
and criteria are listed below:
1.6.1 Minor Defect: A defect that is not likely to materially reduce the usability of a
system or component for its intended purpose; or is a departure from established standards
having no significant bearing on the effective use or operation of the system or component.
1.6.2 Major Defect: A defect greater than minor limits that requires repair or replacement
of the part to restore the full load carrying capacity of the structure. All cracks are
considered major defects.
1.6.3 Critical Defect: Any defect that results in a hazardous or unsafe condition for
persons operating the aircraft, or a defect that is likely to prevent performance of the tactical
function of the aircraft. All critical defects shall be briefed to the Unit Commander or his
designated representative (hereafter referred to as the Unit Commander), and the affected
service on the discovery of the defect.
REPORTING AND DOCUMENTATION:
The JACE team will complete the JACE
administrative procedures form, the JACE checklist, and the discrepancy summary forms for all the
major and critical defects using the automated JACE database during the execution of the JACE.
1.7.1 JACE Administrative Procedures: The Administrative Procedures Form provides
the JACE Team with the aircraft background, and provides the services with information to
assist in trend analysis of the aircraft or fleet. Information to complete the form can be
gathered from the aircraft logbook. An example of the Administrative Procedures Form is
1.7.2 JACE Report Form: The JACE Report is the completed JACE Administrative

automated JACE data base, select the appropriate defect(s) or no defect, and classify the
defect(s) as Minor, Major, or Critical.
1.7.3 Unit Out-briefing: The JACE Team Leader shall provide an out-briefing to the Unit
Commander on the JACE results. The briefing will be consistent with the overall aircraft
condition reported on the Administrative Procedures Form. A copy of the JACE Checklist,
