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

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

National Wildland Firefighter Day

Date: July 2, 2025
Questions?  Please contact:
National Interagency Fire Center

The National Wildfire Coordinating Group (NWCG) recognizes July 2, 2025, as National Wildland Firefighter Day (NWFFD). Established in 2022, NWFFD honors the dedication of wildland firefighters and support personnel. This day falls within the 2025 Week of Remembrance (June 30 - July 6), providing an opportunity to renew our commitment to wildland firefighter safety while remembering those who have fallen in the line of duty.

NWCG provides leadership to enable interoperable wildland fire operations among federal, state, local, Tribal, and territorial partners. NWCG standards and training establish common practices to contribute to safe, effective, and coordinated interagency wildland fire operations nationwide.

ETC Equipment Bulletin: 25-003 Flame-Resistant Shirt Survey

Date: June 12, 2025
Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.
