The senior member must be a designated naval
aviator or designated naval flight officer. Additionally,
one member of the AMB must be qualified in the Naval
Air Training and Operating Procedures Standards
(NATOPS) if the aircraft involved in the mishap is
manned by an aircrew.
MISHAP INVESTIGATION REPORTS
We report hazards after mishaps by submitting a
mishap investigation report (MIR). These reports are
important in preventing the recurrence of aircraft
mishaps. Success of the Naval Aviation Safety Program
depends on the submission of brief, open, and forthright
information, opinions, and recommendations. The
exercise of command influence to edit, change, or in any
way censor the content of MIRs is prohibited since that
would be contrary to the spirit of the program. Should
any senior commander have a comment to make on the
content of an MIR, that officer should make that
comment in an endorsement of the report.
Purpose of an MIR
The purpose of an MIR is to provide information
needed to fix mishap cause factors. Each cause factor
has three elements associated with it that precisely
describe the personnel, equipment, actions/events, and
reasons for the mishap. Determining the elements
determines the cause factors, which identifies the
starting point for remedial action. We use MIRs to report
those hazards that caused the reported mishap and the
damage or injury resulting from the mishap. The report
also provides a means for submitting recommended
corrective action that would prevent recurrence of the
mishap and resulting damage or injury.
Contents of an MIR
An MIR has two parts. The first part, Part A,
consists of the list of nonprivileged information
extracted from paragraph 10 of the MIR, the final MR
message, and enclosures specified in chapter 7 of
OPNAVINST 3750.6Q. Enclosures to MIRs serve two
purposes. One is to provide additional data on the
mishap that can be coded and entered in the
NAVSAFECEN data bank or used as research material.
The second purpose is to clarify points of evidence that
cannot be made in the body of the MIR message. Part B
is privileged. It includes a copy of the complete MIR
message, Part B enclosures, and all endorsements. For
further information, consult chapter 7 of OPNAVINST
Submitting an MIR
Submit MIRs within 30 calendar days following the
mishap. In the case of missing aircraft, submit the MIR
within 30 calendar days after completion of the
organized search. The originator of the MIR is usually
the appointing authority of the Aircraft Mishap Board
(AMB). Usually, the appointing authority is also the
reporting custodian of the aircraft involved in the
You must submit MIR messages through military
radio/electronic communications facilities. Send
enclosures with one copy of the MIR message by mail
to the Naval Safety Center.

HRs, MRs, and MIRs.
HAZARD REPORT AND MISHAP
The endorsement of both HRs and MIRs is an
important step in eliminating many major hazards.
Endorsements provide an opportunity for seniors in the
chain of command to add their broader perspective and
authority to the process of recommending corrective
Purpose of Endorsements
The ultimate purpose of endorsements is to
eliminate the hazards described in the reports.
Endorsements convey the position of the endorsers on
the matters contained in the endorsed report.
Review of Reports and Enclosures
The endorsement of MIRs and HRs requires careful
review of submitted reports and previous endorsements.
Any endorser in the chain of command who believes an
investigation is incomplete or an MIR or HR is
inadequate should take corrective measures. Those
measures should ensure an adequate investigation of the
mishap or resubmission of the report. Any endorser may
get copies of specific enclosures to the MIR by
requesting them from the appointing authority of the
