SYSTEM: SEAT, Aircraft

Sub-System	Hazards	Pre-Mitigation			Mitigation	Post-Mitigation
Sub-System	Hazards	Probability	Severity	Risk Level	Mitigation	Probability	Severity	Risk Level
Capabilities	High density altitude affects the aircraft performance	Almost Certain	Critical	Extremely High	Assign appropriate SEAT aircraft for mission and typical DA. Conduct pre-mission performance planning. Reinforce high/hot/heavy training. Complete load calculation before flight.	Unlikely	Critical	Medium
Capabilities	Inappropriate aircraft for mission	Possible	Critical	High	Ensure SEAT is appropriate for temperatures, altitude, terrain, fuel type and mission. Receive feedback from pilots and aerial supervisor. If not effective, order different/additional aircraft.	Unlikely	Critical	Medium
Maintenance	Mechanical failure	Possible	Catastrophic	Extremely High	Pilot and SEMG monitor maintenance schedule. Vendor follows maintenance/overhaul schedule. Pilot reviews and understands emergency procedures.	Unlikely	Critical	Medium
Maintenance	Aircraft improperly maintained	Possible	Catastrophic	Extremely High	Follow contract/FAA requirements and aircraft maintenance manual. Aircraft inspectors check that FAA maintenance requirements are met. Pilot performs/ensures that daily pre- and post-flight inspections are complete and that all life and time limit maintenance items are completed per maintenance manual.	Unlikely	Critical	Medium
Collision Avoidance	Visibility	Almost Certain	Catastrophic	Extremely High	Keep windscreen clean. Aircraft will have high-visibility paint scheme. Pilot and ground resources must maintain situational awareness. Only fly during VFR conditions.	Unlikely	Critical	Medium
	Un-used or inoperable high-visibility aircraft lighting systems	Possible	Critical	High	Landing and strobe lights need to be maintained and utilized as required by contract and aerial supervision guide. If lighting is inoperable, aircraft will return to base until repaired.	Unlikely	Critical	Medium
	Congested airspace, military airspace, uncontrolled airports	Almost Certain	Catastrophic	Extremely High	Aircraft will have operable collision avoidance system (TCAS), rate-of-climb indicator, gyro, and aeronautical charts for area of operations. Pilot will review known aerial hazards prior to flight. Practice see and avoid.	Unlikely	Catastrophic	High
Aircraft Carding and Pilot Inspection Process	Lack of standardization	Possible	Moderate	Medium	Ensure implementation of standardized SEAT aircraft and pilot inspection process. Train inspectors on new standards. Ensure SEMGs are knowledgeable on pre-use inspection process.	Unlikely	Moderate	Medium
Equipment	Aviation maintenance inspectors unfamiliar with SEAT aircraft	Possible	Critical	High	Train and utilize more Interagency aviation maintenance inspectors (include all agencies) with past SEAT program experience and knowledge.	Unlikely	Critical	Medium
	Locations of cockpit controls and switches not consistent/standardized	Possible	Moderate	Medium	Establish standard configuration in SEATs. Allow relief pilots time for orientation in each aircraft prior to mission operations.	Rare	Negligible	Low
	Inadequate pre-flight/post-flight inspections	Possible	Critical	High	Agency reps and vendor personnel should ensure adequate revenue time for pre- and post-flight inspections. Document pre- and post-flight inspections daily.	Unlikely	Moderate	Medium
Communications	Changing technology and lack of training	Likely	Critical	Extremely High	During the inspection and carding process ensure contractors (pilots) are skilled with equipment provided–GPS, VHF and UHF radios, AFF, etc.	Unlikely	Critical	Medium
	Communication with non-federal fire departments - lack of radio equipment compatibility (narrow banding and frequencies)	Possible	Critical	High	Continue to work with state, city and county fire departments to meet future federal standards and compatibility issues. Work with national agency/interagency radio program leaders to ensure the policies they develop are compatible with aviation requirements.	Unlikely	Critical	Medium
	Inadequate frequency management	Almost Certain	Catastrophic	Extremely High	Conduct effective air base in-briefings, including relief pilots. Ensure pilot has adequate time for orientation/programming before mission flights. Conduct frequent AARs and/or specialized training simulation exercises. Perform periodic reviews of frequency lists and avionics equipment operations. Check radio systems following days off. Ensure that positive communications are established.	Unlikely	Critical	Medium
	No communications between SEAT pilot and ground/air ops	Possible	Catastrophic	Extremely High	Follow appropriate checklists and procedures. Do not drop on fire line unless sure area is clear of ground personnel. If no contact can be established on incident return to base.	Unlikely	Critical	Medium
	Radio frequency congestion	Almost Certain	Critical	Extremely High	Make alternative frequencies readily available and known. Order additional frequencies as needed. Utilize AFF when possible to reduce congestion. Maintain effective working relationships with frequency coordinators. During high-fire activity consider ordering standalone frequency coordinator.	Unlikely	Critical	Medium
	Lack of flight following frequencies	Likely	Critical	Extremely High	Request local flight following frequencies whenever possible. Utilize standardized AFF procedures. Utilize national flight following if necessary. Utilize Air Guard as a last resort for initial contact for flight following.	Unlikely	Critical	Medium

LMC Equipment Bulletin 26-001: Aquatic Invasive Species – Seasonal Reminder for Mussels

Date: July 30, 2026
Questions?
Please contact: Equipment and Technology Subcommittee

The Logistics and Equipment Management Committee (LMC) issued Equipment Bulletin 26-001: Aquatic Invasive Species - Seasonal Reminder for Mussels, reminding the wildland fire community that aquatic mussels continue to be a problem. Mussels rapidly colonize hard and soft surfaces, including aquatic plants and fire equipment, clogging pipes, fouling motors, disrupting water systems, and impacting native species.

To help prevent their spread, fire personnel must follow the decontamination procedures outlined in the NWCG Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations, PMS 444. Additionally, report any sightings immediately to your Lead Resource Advisor and include clear, close-up photos (with a pen or your hand for size reference) and location details.”

Read the complete LMC Equipment Bulletin 26-001, to learn more.

Intermediate Faller (FAL2) Position Task Book Update

Date: July 24, 2026
Questions?
Please contact: Tree Felling Subcommittee

NWCG Operations Management Committee (OMC) has issued an update to the NWCG Position Task Book for Intermediate Faller (FAL2), PMS 311-91. To ensure clarity for both trainees and evaluators, the updated FAL2 Position Task Book (PTB) explicitly states who is authorized to sign off on your tasks:

“Evaluators must be qualified as a FAL2, or an Advanced Faller (FAL1).”

If you are currently working out of a previously published version of the FAL2 PTB, you do not need to restart. However, OMC highly encourages you to take the following step to prevent any confusion in the field:

Print and replace the updated evaluator information page (page 2) in your current physical PTB.
