of aircraft, equipment or facilities. Any explosive
mishap involving aircrew error must be reported
using the latest edition of OPNAVINST 3750.6
or OPNAVINST 5102.1.
2. When a malfunction or failure of an
explosive system is found to be caused by failed
material. This report is a combined EMR/QDR
or EMR/EI as appropriate.
3. When urgent action or assistance is
required to correct a deficiency at an early date
because of an operational commitment.
4. When an urgent change to ordnance
loading or launch device/AWSE safety instruc-
tions is required to prevent a hazardous condition
5. When a condition is detected that could
cause incorrect installation and subsequent system
malfunction due to the design of a part.
ENGINEERING INVESTIGATION (EI)
The EI comprises three types of investigation:
disassembly and inspection, material analysis, and
engineering assistance. Only the disassembly and
inspection procedures will be discussed in this
section since the procedures for requesting any of
the three types of investigation are the same.
Engineering investigations (fig. 5-3) are
requested by a routine precedence message within
5 working days after discovery of the deficiency,
unless combined with an HMR/EI, under one or
more of the following conditions:
1. When safety is involved. This includes EI
requests prepared in conjunction with accidents/
incidents, ground accidents/incidents, and
impending malfunctions when it is evident that
an unsafe condition exists.
2. When additional technical or engineering
information is required to complete an accident
3. When aircraft readiness is seriously
impaired due to poor material (including SE)
4. When a component is rejected by the Navy
Oil Analysis Program (NOAP) after attempted
authorized repairs are exhausted at the
organizational and intermediate levels.
5. When specifically directed by higher
All requests for EIs are submitted to the CFA,
which will study the history of similar equipment
failures and determine the potential value of
conducting an EI on the equipment in question.
If the study indicates that an EI is not required,
the CFA so informs (by message) the requesting
activity. If the study indicates an EI is warranted,
the CFA assigns a control number to the
investigation and provides shipping instructions
to the requesting and holding activities by
message. Whether an EI is warranted or not, the
CFA must respond by message within 5 calendar
days after receipt of the EI request to the
requesting activity. For an approved EI request,
the CFA will follow up on equipment not received
from the holding activity within 20 days. Activities
should maintain each EI on file for a period of
This report provides maintenance activities
with a method for reporting deficiencies in new
material or reworked material that may be
attributable to nonconformance to contractual
or specification requirements or substandard
New material is defined as material procured
under contract from industry or manufactured by
an in-house facility that is still under warranty.
All material, whether in actual operation or on
the shelf, is considered new until the warranty
Reworked material is that material over-
hauled, rebuilt, repaired, or modified by
government or commercial activities but unproven
in actual operations.
The category I (CAT I) QDR is a report on
a quality deficiency, which will, or may, affect
life or limb of personnel or impair the combat
capabilities of the using organization or individual
or that affects operational capability to the extent
that mission accomplishment is jeopardized. The
category II (CAT II) type of QDR is made on all
other deficiencies that do not meet the criteria set
forth in category I.
