Equipment Provisions
Equipment can be exempted for up to seven years.
The number of pieces of equipment that can be exempted or “flexed” vary depending on the type of allowance and power category.
Power Categories
There are two options for power categories [is this correct? it's what I inferred]:
- General availability OR
- Delayed availability
Program availability varies per power category.
- For more information, see: Program availability
Allowances
Participants:
- Must choose one of two allowances:
- Percent of Production Allowance OR
- Small Volume Allowance, which is:
- Single engine family, OR
- Multiple engine families
- Can claim only one allowance per power category for the life of the program.
