HAZMAT Information

Updated December 28, 2018

The Federal Aviation Administration (FAA) has amended hazardous materials (hazmat) training requirements for all Part 135 on-demand operators and many Part 145 repair stations. The amended regulations affect “will-carry” and “will-not-carry” Part 135 operators, as well as Part 145 repair stations providing services to those operators.

The rule became effective on November 7, 2005. However, certificate holders have until February 7, 2007, to comply. In the interim, operators may continue to comply with the existing rules or may opt to begin complying with the new regulations at any time before February 7, 2007.

Part 135 Changes

1. Training
The amended rule requires hazmat training for each crewmember and person performing or directly supervising transport-related functions for Part 135 operations. The training must meet the requirements of Appendix O of Part 121, and recurrent training is required every 24 months.

An FAA-approved training program is required for both will-carry and will-not-carry operators. Training is required for any crewmember or person performing or directly supervising the following functions involving items for transport on board an aircraft:

· Acceptance;
· Rejection;
· Handling;
· Storage incidental to transport;
· Packaging of company material (COMAT); or
· Loading.

Because hazmat training is required for all individuals participating in the above job functions, untrained assistance in loading an aircraft is prohibited, even if the certificate holder is a will-not-carry operator.

2. Notification of Repair Stations
Part 135 certificate holders must ensure that each repair station performing work for the certificate holder has been notified in writing of the certificate holder’s will-carry or will-not-carry status and applicable hazmat policies.

3. Records
Each certificate holder must retain records for hazmat training completed within the preceding three years. The records must be made available upon request at the location where the trained person performs or directly supervises the job. Records may be maintained electronically.

4. Exception for Foreign Locations
An exception to the training rule applies to certificate holders operating in a foreign country where the country requires the certificate holder to use persons working in that country to load the aircraft. In only this case, the certificate holder may use persons who have not been trained under the operator’s hazmat program to load the aircraft under the direct supervision of someone who has completed the operator’s training.

Part 145 Changes
1. Acknowledgement of Air Carrier Hazmat Status
When a repair station receives written notification of an air carriers hazmat status and policies, the repair station must acknowledge receipt of the information (in writing) prior to performing work for that certificate holder.

2. Training Required
If repair station employees are involved in the loading of items for transport on a Part 121 or 135 aircraft, those employees must be trained under the air carrier’s hazmat training program.

3. Certification to FAA of Training
Before issuance of a Part 145 certificate or rating the repair station must certify to the FAA that all “hazmat employees” are trained as required. The certification must also be provided when a certificate is amended or transferred (unless it was previously submitted).
