POLICY DIRECTIVE GOVERNING THE EXECUTION OF THE
JOINT AIRFRAME CONDITION EVALUATION (JACE)
IN THE FIELD FOR ARMYAND AIR FORCE
ALL H-60 AIRCRAFT
INTRODUCTION AND GENERAL INFORMATION
PURPOSE AND BACKGROUND:
1.1.1 The Joint Airframe Condition Evaluation (JACE) criteria provide a method for the
Tri--Service Users of the H-60 deritive airframe to identify candidates that require corrective depot-level
maintenance action. This method utilizes a set of common faults, called condition codes, to permit evalu-
ators to make an effective, objective assesment of specific factors judged most critical in determining the
need for depot-level maintenance action. This evaluation consits of an examination of the aircraft struc-
ture for symptoms of possible hidden defects, together with an assesment of overall system material con-
1.1.2 These criteria replace the Airframe Condition (ACE), as used previously in the
U.S Army and Air Force.
1.1.3 The JACE pertains principally to structural parts that are replaceable at depot-
level; however, abnormal conditions and/or defects observed will be recorded for disposition at the ap-
propriate level of maintenance. This evaluation does not pertain to components or time change items,
except as how they impact overall maintenance.
This directive, along with the Implementation Plan defines the actions required
and the responsibilities of the affected organizations in order to replace the current ACE inspectionpro-
grams with the JACE.
A Corrosive Prevention and Control Evaluation (CPCE) is defined in Appendix E.
Aircraft: Aircraft that are encompassed by this JACE directive include the follow-
The UH-60A/L, EH-60A/L, and MH-60A/L/K BLACK HAWK aircraft.
The HH-60G PAVE HAWK aircraft.
2.1.2 Inspection Intervals: All aircraft, except as noted in paragraph 2.2 are to be
evaluated each year within a period of minus 6 months to plus 90 calendar days of either of the following
