LAWS, REGULATIONS, AND CODES

Regulation of model rocketry is broken into two classes with different regulations applied to each.

  1. Model Rocketry
  2. High-Power Model Rocketry

Model Rocketry

There are generally few regulations applied to model rocketry, with most of those applied at the state and local level. Forty eight states (all but Rhode Island and California) adhere to a common code of regulations for model rocketry known as National Fire Protection Association (NFPA) Code 1122. This code defines the power, weight, and other limits to which a rocket must comply in order to be classified as a "model rocket."

At the Federal level, according to FAR 101.1 model rockets are exempt from FAA regulation, provided they are operated in a manner so as not to pose a hazard to aircraft. The only exception to this rule is that if a model rocket weighs between 454 and 1,500 grams, you must notify the nearest FAA control tower before launching them. Model rocket kits and motors do come under the jurisdiction of the Consumer Product Safety commission where they must satisfy the same basic product safety requirements as toys.

The State of California treats model rockets as a special class of fireworks and requires:

  1. You must be at least 14 years old to purchase model rocket engines (1/4A through D class).
  2. You must be at least 18 years old to purchase engines larger than D.
  3. To launch, you must secure the written or verbal permission of the local fire authority having jurisdiction over the location where you wish to launch.

The City of Livermore requires that you get a permit from the City Fire Marshal and that you have at least a million dollars of liability insurance. There are currently only two permit holders in the city of which LUNAR is one.

High-Power Rocketry

The second class of rockets are High-Power Model rockets. A rocket is considered high-power if it exceeds any of the following.

  • Uses a motor with more than160 Newton-seconds of total impulse (an "H" motor or larger) or uses multiple motors that all together exceed 320 Newton-seconds of total impulse.
  • Uses any motor with a thrust of more than 80 Newtons average thrust
  • Has a launch weight (including the engines) of more than 1,500 grams
  • Includes any airframe parts of fiberglass or ductile metal
  • Is powered by a pre-manufactured motor that involves any assembly by the modeler.

High-power model rockets fall under a different code of regulations from those for model rockets. The high-power regulations are known as National Fire Protection Association (NFPA) Code 1127. This is a relatively new code (1995) and so most states have not yet had time to adopt it. You should check your own state's laws before attempting to launch high power rockets.

In addition, high power rockets and motors are directly regulated by the federal government including the FAA and the BATF.

  • Before you can purchase engines and fly high-powered model rockets, you must apply for and receive an FAA waiver, The purpose of this waiver is to arrange for air traffic to be routed clear of your flight area.
  • You must also apply for and receive a BATF Low Explosives User Permit before taking receipt of any rocket motors exceeding 62.5 grams of propellant. This involves, among other things, constructing a "magazine storage" for the engines that is compliant to federal standards.

NAR Model Rocket Safety Code (Revision of ?????)

1. Materials. My model rocket will be made of lightweight materials such as paper, wood, rubber, and plastic suitable for the power used and the performance of my model rocket. I will not use any metal for the nose cone, body, or fins of a model rocket.

2. Motors. I will use only commercially-made, NAR-certified model rocket motors in the manner recommended by the manufacturer. I will not alter the model rocket motor, its parts, or its ingredients in any way.

3. Recovery. I will always use a recovery system in my model rocket that will return it safely to the ground so it may be flown again. I will use only flame-resistant recovery wadding if wadding is required by the design of my model rocket.

4. Weight and Power Limits. My model rocket will weigh no more than 1,500 grams (53 ounces) at lift-off and its rocket motors will produce no more than 320 Newton-seconds (71.9 pound-seconds) of total impulse. My model rocket will weigh no more than the motor manufacturer's recommended maximum lift-off weight for the motors used, or I will use motors recommended by the manufacturer for my model rocket.

5. Stability. I will check the stability of my model rocket before its first flight, except when launching a model rocket of already proven stability.

6. Payloads. My model rocket will never carry live animals (except insects) or a payload that is intended to be flammable, explosive, or harmful.

7. Launch Site. I will launch my model rocket outdoors in a cleared area, free of tall trees, power lines, buildings, and dry brush and grass. My launch area will be at least as large as that recommended in the accompanying table.

8. Launcher. I will launch my model rocket from a stable launch device that provides rigid guidance until the model rocket has reached a speed adequate to ensure a safe flight path. To prevent accidental eye injury, I will always place the launcher so the end of the rod is above eye level or I will cap the end of the rod when approaching it. I will cap or disassemble my launch rod when not in use and I will never store it in an upright position. My launcher will have a jet deflector device to prevent the motor exhaust from hitting the ground directly. I will always clear the area around my launch device of brown grass, dry weeds, or other easy-to-burn materials.

9. Ignition System. The system I use to launch my model rocket will be remotely controlled and electrically operated. It will contain a launching switch that will return to "off" when released. The system will contain a removable safety interlock in series with the launch switch. All persons will remain at least 15 feet from the model rocket when I am igniting model rocket motors totalling 30 Newton-seconds or less of total impulse and at least 20 feet from the model rocket when I am igniting model rocket motors totalling more than 30 Newton-seconds of total impulse. I will use only electrical igniters recommended by the motor manufacturer that will ignite model rocket motors within one second of actuation of the launching switch.

10. Launch Safety. I will ensure that people in the launch area are aware of the pending model rocket launch and can see the model rocket's lift-off before I begin my audible five-second countdown. I will not launch my model rocket so its flight path will carry it against a target. If my model rocket suffers a misfire, I will not allow anyone to approach it or the launcher until I have made certain that the safety interlock has been removed or that the battery has been disconnected from the ignition system. I will wait one minute after a misfire before allowing anyone to approach the launcher.

11. Flying Conditions. I will launch my model rocket only when the wind is less than 20 miles per hour. I will not launch my model rocket so it flies into clouds, near aircraft in flight, or in a manner that is hazardous to people or property.

12. Pre-Launch Test. When conducting research activities with unproven model rocket designs or methods I will, when possible, determine the reliability of my model rocket by pre-launch tests. I will conduct the launching of an unproven design in complete isolation from persons not participating in the actual launching.

13. Launch Angle. My launch device will be pointed within 30 degrees of vertical. I will never use model rocket motors to propel any device horizontally.

14. Recovery Hazards. If a model rocket becomes entangled in a power line or other dangerous place, I will not attempt to retrieve it.
