High-quality, better value.

Core Parts LLC was established in February of 2015 to fulfill a market need. Our capabilities go well beyond those of your average parts supplier. In addition to our extensive PT6 OEM inventory, we are an FAA Production Approval Holder (PAH) certified under 14CFR Part 21 (Approval # PQ05326NM). This approval allows us to develop FAA/PMA replacement parts that are equal to or better than the OEM parts they replace at a cost that is a significantly better value to our customers.


Premier supplier of aftermarket parts.

We are developing our PMA and DER Programs with the intent of becoming the premier supplier of aftermarket parts.  We also stock a large inventory of used serviceable OEM parts that are a great alternative to buying new OEM parts when trying to control costs.  Our goal is to provide our customers with options for the high-quality parts that they need to help them control their DOC without sacrificing quality.


Unparalleled Dedication

We are committed to providing customer support and parts availability that are second to none. Our staff has exceptional product knowledge and will strive to fulfill your aftermarket parts requirements.
