SEAT Accident (Colorado) – August 27, 2008

This Day in History is a brief summary of a powerful learning opportunity and is not intended to second guess or be judgmental of decisions and actions. Put yourself in the following situation as if you do not know the outcome. What are the conditions? What are you thinking? What are YOU doing?

Incident Summary:

A Single Engine Air Tanker (SEAT) is directed by Air Attack to drop on the right flank of the Flat Bush Fire. During the first retardant drop the SEAT’s flight pattern takes the aircraft in close proximity to staged firefighters and vehicles. During the drop sequence the pilot’s side cockpit door comes open and forces him to abbreviate the drop. The pilot relays to Air Attack that he has a problem with his “door”, and having just seen the abbreviated drop, Air Attack assumes the problem door is the retardant gate. He asks several times about the status of the pilot and aircraft. At no time did Air Attack understand that the problem was actually with the cockpit door. The pilot requests to jettison the remaining retardant. Air Attack assumes the problem is corrected and asks the pilot to reinforce the previous drop. The pilot agrees with this request.

On approach for the second drop, the pilot uses an aggressive turn at low altitude to align the aircraft for the drop. The approach is directly over the top of the firefighters again. As a result of the aggressive maneuver, the aircraft stalls and crashes. Debris from the accident damages two wildland fire engines and narrowly misses the six firefighters. The aircraft’s engine lands just 6 feet from an occupied vehicle. The crew is unharmed, the vehicles receive minor shrapnel damage, and although the aircraft is destroyed, the pilot only receives minor injuries.

Discussion Points:

Aerial photo of the mishap site.Apply the concept of LCES to this incident; not from a fire perspective but an aviation point of view.

(L) Lookouts look for hazards (situations and actions) and communicate them. Aircraft flying directly overhead are a hazard. Helicopters accidentally release longlines, buckets and sling loads multiple times each season. Water and retardant drops often miss intended targets, creating the potential for injury by the drops themselves or debris from vegetation.

  • What are options for mitigation if your lookout or others recognize ground forces in a flight path?

(C) Communication: If you see something wrong…say something!

  • Who should ground forces communicate with in the instance of being in a flight path?​

(E & S) Just as for wildland fire, escape routes and safety zones are needed for aviation operations as well. Keep in mind that if something goes wrong with an aircraft, ground crews may not have time to move to a safer location.

  • How can we prepare for and attempt to avoid being in a flight path?

NWCG Latest Announcements

Incident Position Standards and Next Generation Position Task Books Now Available for FBAN and LTAN

Date: Aug 13, 2025
Questions? Please contact:
Fire Behavior Subcommittee

NWCG is excited to announce that Incident Position Standards and Next Generation Position Task Books are now available for Fire Behavior Analyst (FBAN) and Long Term Fire Analyst (LTAN).

The Performance Support Packages for these positions were developed as part of the Incident Performance and Training Modernization (IPTM) effort. These resources support trainees, qualified personnel, and evaluators in their respective roles.

Any changes to qualification pathways will take effect with the next update of the NWCG Standards for Wildland Fire Position Qualifications, PMS 310-1, scheduled for January 2026.

ETC/RMC Safety Bulletin: 25-001 New Guidance on Laundering Wildland Fire Clothing to Reduce Contamination

Date: Aug 8, 2025
Questions? Please contact:
Equipment Technology Committee
 Risk Management Committee

The Equipment Technology Committee (ETC) and the Risk Management Committee (RMC) have issued Safety Bulletin 25-001: Laundering to Decontaminate Wildland Fire Clothing. Recent research revealed that wildland fire flame-resistant pants and shirts can be contaminated with chemicals from combustion byproducts, including carcinogens, and that common laundering practices can effectively remove these harmful contaminants from wildland firefighter clothing more effectively than previously understood. It is recommended to decontaminate wildland fire clothing as frequently as possible. 

Frequently Asked Questions about this new information and how to implement recommendations can be found on the NWCG Alerts page. Read the complete ETC/RMC Safety Bulletin: 25-001 to learn more.

FAQ Now Available for Archiving Type 1 and Type 2 Incident Positions

Date: Aug 6, 2025
Questions? Please contact:
Incident and Position Standards Committee

To support the transition to Complex Incident Management (CIM), NWCG will archive all Type 1 and Type 2 Command and General Staff (C&G) position qualifications in January 2026, as outlined in NWCG Executive Board Memo 25-002. To assist with this transition, a new Frequently Asked Questions (FAQ) document is now available.

This resource answers common questions about the status of Type 1 and Type 2 qualifications, impacts to incident qualification management, training requirements, and resource ordering considerations. Review the full FAQ to learn more.

For additional information on CIM and the transition of C&G positions, see NWCG Executive Board Memos 23-005, 24-005, and 25-002, as well as the Incident Workforce and Development Group webpage.
