Protect Property
NTSB Sec. 831.12 Access to and release of wreckage, records, mail, and cargo.
a. Only the Board's accident investigation personnel and persons authorized by the Investigator-in-
Charge (IIC) to participate in any particular investigation, examination or testing shall be permitted
access to wreckage, records, mail, or cargo in the Board's custody.
b. Wreckage, records, mail, and cargo in the Board's custody shall be released to the DOI or USFS IIC
by an authorized representative of the Board when it is determined that the Board has no further need of
such wreckage, mail, cargo, or records. When such material is released, Form 6120.15, “Release of
Wreckage,'' will be completed, acknowledging receipt.
Treat the accident site like a crime scene. Wreckage, cargo, and debris should not be disturbed or
moved except to the extent necessary:
a. To remove victims.
b. To protect the wreckage from further damage.
c. To protect the public.
In addition to the authority explicit in NTSB 831.12, restricting access protects the public from the
hazards of the accident site.
Initially the accident site should be protected by either your own people (e.g., if the accident occurred at
a fire) or by agency and local law enforcement officers. The investigation team may request extended
security until the investigation is complete.
Preserve Evidence
NTSB Sec. 830.10 Preservation of aircraft wreckage, mail, cargo, and records.
a. The operator of an aircraft involved in an accident or incident for which notification must be given is
responsible for preserving to the extent possible any aircraft wreckage, cargo, and mail aboard the
aircraft, and all records, including all recording mediums of flight, maintenance, and voice recorders,
pertaining to the operation and maintenance of the aircraft and to the airmen until the Board takes
custody thereof or a release is granted pursuant to Sec. 831.12(b) of this chapter.
b. Before the time the Board or its authorized representative takes custody of aircraft wreckage, mail, or
cargo, such wreckage, mail, or cargo may not be disturbed or moved except to the extent necessary:
1. To remove persons injured or trapped.
2. To protect the wreckage from further damage; or
3. To protect the public from injury.
c. Where it is necessary to move aircraft wreckage, mail, or cargo, sketches, descriptive notes, and
photographs shall be made, if possible, of the original positions and condition of the wreckage and any
significant impact marks.
d. The operator of an aircraft involved in an accident or incident shall retain all records, reports, internal
documents, and memoranda dealing with the event, until authorized by the Board to the contrary.
In addition to those items required by law (above) you should also:
Control access to the site by cordoning off the area and contacting the agency aviation safety
investigator to determine who needs access. Request agency or local law enforcement to immediately
