KTM North America, Inc. — Hazardous Materials Safety Interpretation

Page 11200 New Jersey Avenue, SE Washington, DC 20590 U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration July 25, 2023 Mr. John Hinz CEO KTM North America, Inc. 38429 Innovation Court Murrieta, CA 92563 Reference No. 23-0034 Dear Mr. Hinz, This responds to your February 22, 2023, letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to accumulators. Specifically, you are requesting an updated letter of interpretation (LOI) pertaining to the carriage of accumulators in closed-case suspension systems on board passenger-carrying aircraft. You reference LOI No. 15-0220, previously issued to you on February 22, 2016, for the purpose of clarity and confirmation for air carriers of the permitted status of your accumulators. In your most recent letter, you ask whether accumulators meeting the criteria specified in § 173.306(f)(4) and the International Civil Aviation Organization (ICAO) Technical Instructions Special Provision “A114” are subject to the HMR. The answer is no. Accumulators meeting the criteria specified in § 173.306(f)(4) and ICAO Technical Instructions Special Provision “A114” are not subject to the HMR. Provided that your accumulators continue to meet these criteria, shipments of your accumulators would continue to not be subject to the HMR. I hope this information is helpful. Please contact us if we can be of further assistance. Sincerely, T. Glenn Foster Chief, Regulatory Review and Reinvention Branch Standards and Rulemaking Division#

Washington, D.C. 20590 infocntr@dot.gov Re: KTM North America, Inc. Request for Updated Letter of Interpretation regarding 14 C.F.R. § 173.306(f)(4) Dear Mr. Kelley: We are writing in reference to PHMSA's February 22, 2016, letter of interpretation addressed to KTM North America, Inc., Ref. 15-0220, attached hereto as Exhibit A. We request that your office issue to us an updated letter on the same terms and conditions as the 2016 letter, so that we may continue to provide it to air carriers to confirm they are permitted to transport our accumulators. Specifically, we request a renewed letter of interpretation that confirms the carriage of accumulators in closed-case suspension systems on board passenger-carrying aircraft are not regulated as hazardous materials, per the regulatory exception in 49 C.F.R. § 173.306(f)(4) and Special Provision "A114" of the International Civil Aviation Organization (ICAO) Technical Instructions. As described in our original request for a letter of interpretation, - our two racing teams, KTM Motorsports and Husqvarna Motorsports, often transport suspension systems between races on board passenger-carrying aircraft, rather than use dispatch services, which, at times, are unable to deliver the parts in time for a race. We have found that airlines and airline staff at various airports differ in their approaches to the carriage of our accumulators and suspension systems on board aircraft, and we have had to provide them with PHMSA's 2016 letter to demonstrate the permissibility of transporting our parts. Because the letter is now nearly seven years old, some carriers have questioned the letter's continuing validity. We therefore request an updated letter, on the same terms and conditions as the 2016 letter. We confirm that our accumulators meet the criteria as specified in § 173.306(f)(4) and Special Provision "A114". Attached to this letter as Exhibit B are updated technical drawings and specifications of the closed-case suspension systems used by KTM Motorsports and Husqvarna Motorsports. The specifications have not materially changed since our original submission in 2015. The only change is with respect to fitment of newer generation motorcycles. Please contact me should you require any additional information. - Sincerely, / John Hinz CEO cc: Laura Ochoa cc: KTM Legal KM NORTH AMERICA, INC. Murrieta.

Murrieta, CA 92563 Reference No. 15-0220 Dear Ms. Webb: This responds to your letter regarding exceptions for the transportation of accumulators on board a passenger-carrying aircraft under the Hazardous Materials Regulations (HMR: 49 CPR Parts 171-180) and the International Civil Aviation Organizations Technical Instruction for the Safe Transport of Dangerous Goods by Aircraft (ICAO Technical Instructions). Consistent with a previously issued letter of interpretation Ref. No. 09-0105. you ask for confirmation of your understanding that closed-case suspension systems used by KTM Motorsports and Husqvarna Motorsports are not subject to the HMR, provided the accumulators meet all of the requirements of $173.306(f)(4). You attached with your letter documentation from WP Performance Systems, the manufacturer of the suspension systems. substantiating that the systems meet conditions of the ICAO Technical Instructions Special Provision "A114." Your understanding is correct. Accumulators intended to function as shock absorbers, struts. gas springs, pneumatic springs or other impact or energy-absorbing devices are not subject to the HMR. provided they meet the criteria as specified in $ 173.306(f)(4). In addition, articles. containing gas, intended to function as shock absorbers. including impact energy absorbing devices, or pneumatic springs are not subject to the ICAO Technical Instructions. provided each article meets the conditions of Special Provision "A114." if all or part of the transportation is by aircraft. I trust this information is helpful. If you have further questions. please do not hesitate to contact this office. Sincerely. Duane A.

Page 7washington, - Subject: Request for Letter of Interpretation Dear Mr. Betts: We are writing to seek guidance regarding the regulatory exceptions under 49 C.F.R. § 173.306(f)(4) and Special Provision "A114" of the International Civil Aviation Organization (ICAO) Technical Instructions, for the transportation of closed-case suspension systems on board passenger-carrying aircraft. Our two factory racing teams, KTM Motorsports, Inc. and Husqvarna Motorsports, Inc., desire to carry on board its suspension systems between races, ! rather than use dispatch services which are often not available to deliver these parts in time for a race. We are aware of a June 19, 2009 letter of interpretation provided by your office to ShipMate, Inc., in which Kawasaki Racing sought guidance on the carriage of accumulators on board passenger-carrying aircraft. Similarly, we request a letter of interpretation that confirms the suspension systems used by KTM Motorsports and Husqvarna Motorsports are not regulated as hazardous materials, provided that they meet the criteria of 49 C.F.R. § 173.306(f)(4), which state: Accumulators intended to function as shock absorbers, struts, gas springs, pneumatic springs or other impact or energy-absorbing devices are not subject to the requirements of this subchapter provided each: (i) Has a gas space capacity not exceeding 1.6 L and a charge pressure not exceeding 280 bar, where the product of the capacity expressed in liters and charge pressure expressed in bars does not exceed 80 (for example, 0.5 L gas space and 160 bar charge pressure); (ii) Has a minimum burst pressure of 4 times the charge pressure at 20 °C for products not exceeding 0.5 L gas space capacity and 5 times the charge pressure for products greater than 0.5 L gas space capacity; KTM NORTH AMERICA, INC. 1119 Milan Avenue / Amherst, OH 440DJ /: T: 440-985-3553 / F: 440-985-3060 38429 Innovation Court /i Murrieta, CA 92563 1 1: 951-600-8007 1/ F: 951-600-8866 www.ktmusa.com#

Page 8copy of the quality assurance program must be maintained at each facility at which the accumulators are manufactured. We have attached documentation from WP Performance Systems, the manufacturer of the suspension systems, which substantiates that the suspension systems fully comply with ICAO Technical Instructions, Special Provision "A114," and therefore with all the requirements of 49 C.F.R. § 173.306(f(4) as well. Thank you for your time and assistance in this matter. Please contact me should you require any additional information. We look forward to your response.
