01 / PMA parts

Aircraft parts, developed from maintenance experience.

Replacement components for wheels, brakes, and landing gear, designed around the way these parts actually wear, and documented for approval under the PMA framework.

What PMA means for an operator.

Parts Manufacturer Approval (PMA) lets an independent company produce replacement parts for certificated aircraft once the design and manufacturing processes are approved by the aviation authority. It is how the industry gets a credible alternative to OEM-only supply.

For a maintenance operation, that alternative matters most on high-wear parts: components replaced at nearly every overhaul, where the price and lead time of a single item can decide whether a job is profitable, or even possible.

From shortage to supplied part

  1. Start with a real shortage

    We look for components that are costly, slow to obtain, or both, the kind that routinely hold an aircraft in the hangar.

  2. Study the original in service

    Worn and failed parts show where loads concentrate and where material gives up. That evidence shapes the design, not just the drawing.

  3. Design and document

    Geometry, materials, and processes are defined and documented to support the certification pathway for each part.

  4. Supply with a straight answer

    Each enquiry gets a clear response on status, lead time, and suitability for your requirement, confirmed in writing.

AMT does not represent any part as approved, interchangeable, or eligible for a specific aircraft unless confirmed in writing for your requirement.
