Navy Aircraft Crashes: What Happens After a Mishap and How the Navy Investigates

When a Navy aircraft crashes, the Navy calls it a mishap, and a set process begins at once. Crews are rescued or recovered, families are told before any names are made public, and a board of investigators starts work to find out what happened so that it does not happen again.

If you are reading this because of something in the news, it can be hard to tell what is known from what is rumour. Early reports are often wrong, and the Navy says very little in the first days. There are good reasons for that.

This guide explains how the Navy classifies an aircraft mishap, who investigates and why most of the findings stay private, what families can expect, and how to find reliable information. It is based on the Naval Safety Command’s own published guidance.

Why the Navy says “mishap”

You will rarely see the Navy use the word “accident”. It uses mishap.

The choice is deliberate. “Accident” suggests something that could not have been prevented. Naval aviation works from the opposite belief: that nearly every mishap has causes that can be found and fixed. The whole system that follows a crash is built on that idea.

A mishap also covers far more than a crash. A hard landing, an engine damaged by a loose tool, or an injury on the flight deck can all be mishaps.

The five mishap classes

The Navy grades every mishap by how much damage was done and how badly people were hurt. The Naval Safety Command publishes the definitions.

Source: Naval Safety Command, “Current Mishap Definitions”. The cost thresholds have applied since 1 October 2019.

A mishap is placed in the highest class it qualifies for. An aircraft that is badly damaged with nobody hurt can still be Class A on cost alone. Modern aircraft are so expensive that even damage which looks minor can cross the threshold.

A “Class A mishap” in a headline does not always mean a crash, and it does not always mean someone died. It means the event met the most serious threshold for cost or injury.

How often does it happen?

The Naval Safety Command publishes mishap statistics for the public. Its summary for the fiscal year that ended on 30 September 2026 shows 16 Class A aviation mishaps on its headline chart, which counts crewed and uncrewed aircraft together. That is a rate of 2.23 for every 100,000 flight hours. The year before, the figures were 12 and 1.60. The ten-year average was about 11 a year.

Numbers like these move up and down from year to year, and a single year proves little. What matters to the people who study them is the long-term trend and the causes behind each event.

The first hours after a crash

Before any investigation begins, there are more urgent jobs.

1. Rescue. Search and rescue starts immediately. At sea, that often means a helicopter and nearby ships. Ashore, it involves local emergency services as well.
2. Making the scene safe. A crash site can be dangerous long after the event. There may be fuel, ammunition, ejection seat charges and sharp carbon fibre debris.
3. Protecting the evidence. Wreckage, recordings and maintenance records are secured so that investigators see them untouched.
4. Telling the families. If anyone has been killed, seriously hurt or is missing, the Navy notifies their next of kin in person wherever it can.
5. A first public statement. The Navy confirms that a mishap has happened. It usually gives the type of aircraft and the general location, and little else.

Why names are held back

The Department of Defense does not release the names of those killed until after their families have been told, and it normally waits a further 24 hours. The aim is simple. Nobody should learn of a death from a news site or a social media post.

This is why early reports say “a pilot” or “two crew members” and nothing more. It is not secrecy for its own sake. It is the Navy keeping a promise to its families.

Two investigations, two different jobs

This is the part that confuses people most. A serious mishap can lead to two separate investigations, run by different people for different reasons.

The two are kept apart on purpose. Each one works because the other exists.

The safety investigation

For aircraft, the safety investigation is carried out by an Aviation Mishap Board. Other kinds of serious mishap get a Safety Investigation Board.

The Naval Safety Command describes the task plainly. Boards are convened to determine the causal factors and to make internal recommendations to Navy and Marine Corps leaders, so that similar mishaps can be prevented.

When a formal board is required

Navy and Marine Corps policy requires a formal board for, among other things:

• all on-duty Class A mishaps, on or off base;
• cases where damage to Department of Defense property is expected to exceed $2,500,000;
• an on-duty injury where death or permanent total disability is likely;
• Class A explosives mishaps.

Who sits on the board

Board members are officers and specialists, usually with experience of the aircraft involved. Investigators from the Naval Safety Command do not sit on the board. They act as expert advisers to it and help it follow the proper process.

Why the findings stay private

People often assume a report is being hidden. In fact the confidentiality is the reason the system works.

Safety investigators need the truth, quickly. A pilot or a maintainer is far more likely to say “I made a mistake” if they know their words cannot be used to punish them. So what witnesses tell a safety board is protected. The Naval Safety Command calls this privileged safety information.

That protection is recognised by the courts. Because of it, the Naval Safety Command says investigation reports and findings are not typically released to the public. The commander of the Naval Safety Command is the Department of the Navy’s only authority for releasing privileged safety information.

The command or legal investigation

Alongside the safety board, the chain of command may order its own investigation. It is often called a JAGMAN investigation, after the legal manual that governs it.

This one gathers facts for different purposes. It can be used to settle claims, to decide whether an injury or death happened in the line of duty, and to decide whether anyone should be held to account.

Because it is not built on confidential safety statements, this is the investigation that members of the public and the press can usually ask to see, through a Freedom of Information Act request. Private and sensitive details are removed first, and the process can take a long time.

What investigators look for

No two mishaps are the same, but investigators work through the same broad questions each time.

It is rare for a mishap to have a single cause. Usually several things line up: a tired crew, a small mechanical fault and bad weather, for example. Take away any one and the mishap might not have happened. That is why investigations look so widely.

How the Navy tries to prevent mishaps

Flying from ships is among the most demanding things any military does. Our guide to US aircraft carriers explains how much has to go right on every launch and landing. A great deal of effort goes into keeping it safe.

• Standard procedures. Every aircraft type has a detailed manual for how it must be flown and what to do in an emergency.
• Inspections and maintenance. Aircraft are checked before and after every flight and at set intervals. The photo at the top of this guide shows sailors inspecting landing gear in a carrier’s hangar bay.
• Risk management. Crews are taught to identify hazards before a flight and decide how to reduce them.
• Reporting near-misses. Sailors are encouraged to report hazards and close calls, including anonymously, so that problems are fixed before anyone is hurt.
• Safety stand-downs. After a serious mishap, or a run of them, units may stop flying for a day to review procedures.
• Sharing lessons. The Naval Safety Command publishes statistics, summaries and lessons learned.

What families can expect

If a sailor is killed, seriously injured or missing, the Navy assigns the family a Casualty Assistance Calls Officer, often shortened to CACO. This is a uniformed officer or senior enlisted leader whose only job is to help that family.

• They deliver the news in person wherever possible.
• They stay with the family through the days and weeks that follow.
• They explain benefits and entitlements and help with the paperwork.
• They help with funeral and memorial arrangements and with travel.
• They are the family’s link to the Navy for questions about the investigation.

Other support is available too. The Navy-Marine Corps Relief Society can help with urgent costs. Fleet and Family Support Centers and chaplains offer counselling. Our guide to military service organizations lists more places to turn.

How to find reliable information

You will find the official sites in our master Navy links list.

If you see a military aircraft go down

1. Call 911. Give the location as exactly as you can.
2. Keep well away. Wreckage can burn, explode or give off harmful dust and fumes.
3. Do not touch or take anything. Debris is evidence, and it may be dangerous.
4. Tell the authorities what you saw. Your account may help investigators.
5. Think before you post. Avoid sharing images that show crew members or identifying marks until the Navy has spoken.

Real-life situations

1. A crash is in the news and your sailor is at sea

The Navy contacts families directly and quickly when someone is hurt. If you have not heard anything, that is good news. Do not rely on social media, and do not call the ship. Your command’s ombudsman is the right person to ask.

2. You are a sailor and your squadron has had a mishap

Tell the safety board the truth. What you say to it is protected, and it may save a life. Look after each other, and use the chaplain or counsellors if you need them.

3. You want to know what caused a particular crash

The safety report will not be released. A command investigation may be, in time. Search for official statements first, then news reports that cite the released investigation.

4. You are worried about your child joining naval aviation

The concern is natural. It may help to know how much effort goes into safety, and that the great majority of flights end without incident. Talk it through together.

5. You are writing about a mishap for school or work

Use the official mishap classes, cite the Navy’s own statements, and be clear about what is confirmed and what is not.

Frequently asked questions

What is a Class A mishap in the Navy?

A Class A mishap is the most serious category. It involves a death or permanent total disability, a destroyed aircraft, or property damage of 2.5 million dollars or more.

Who investigates a Navy aircraft crash?

An Aviation Mishap Board carries out the safety investigation, advised by investigators from the Naval Safety Command. The chain of command may also order a separate command or legal investigation.

Are Navy mishap investigation reports made public?

Safety investigation reports are normally not released, because they contain privileged safety information. A separate command investigation can often be requested under the Freedom of Information Act, with private details removed.

Why does the Navy not release names straight away?

The Department of Defense does not release the names of those killed until their next of kin have been notified, and it normally waits a further 24 hours.

Why does the Navy say mishap and not accident?

Because naval aviation works on the principle that mishaps have causes that can be identified and prevented, which the word accident does not convey.

Who helps the family after a Navy mishap?

A Casualty Assistance Calls Officer is assigned to the family to deliver the news, explain benefits, help with arrangements and act as their link to the Navy.

Your quick-reference checklist

• Mishap classes run from A to E. Class A is the most serious.
• Class A: a death, a permanent total disability, a destroyed aircraft or $2.5 million in damage.
• Two investigations: one for safety, one for facts and responsibility.
• Safety findings stay private so that people speak honestly.
• Names are released only after families are told.
• Trust official statements over social media.
• Never share names or guesses.
• If you witness a crash: call 911 and keep away.

Behind every mishap report are real people: the crew, their families and the shipmates who carry on flying. The Navy’s process is slow and quiet by design. It exists to look after those people, and to make sure that whatever went wrong is not repeated.
