Parts Manufacturer Approval (PMA)
Parts Manufacturer Approval (PMA) is a combined design and production approval for modification and replacement parts. It allows a manufacturer to produce and sell these parts for installation on type certificated products. We approve materials, processes, appliances and other parts by other means like a Technical Standards Order (TSO) or in conjunction with a type certificate. Order 8110.42 prescribes the approval procedures for FAA personnel and guides applicants in the approval process.
