There’s no such thing as something for nothing. But sometimes, you can get more than you ever expected out of a bargain. PMA parts are a great example. They are generally much less expensive than parts sold by the original equipment manufacturers (OEMs). There are a number of reasons for this. Sometimes, the PMA holder is also the real supplier to the OEM, and therefore the so-called OEM’s pricing represents a mark-up from the price offered by the actual producer of the part. Another reason is because of the business model used by many engine manufacturers, who will sell an engine to an air carrier for less than its market value with the expectation of making an inflated profit from the aftermarket parts. PMA parts can be sold at a more commercially reasonable price and drastically undercut the super-inflated prices of the OEMs. Sometimes, the fact that PMA parts are designed and approved later than the OEM parts means that they are able to take advantage of new manufacturing techniques that were not available to the OEM, which can lead to lower manufacturing costs and tighter manufacturing tolerances for PMA parts.
We are facing an opportune moment in the history of PMAs.
For years, the large engine manufacturers criticized PMA parts; and for years, we answered criticisms about PMA parts with basic education. Now, GE has purchased a new subsidiary that holds PMAs (and GE has had a number of PMAs reissued in its own name); and Pratt & Whitney has applied for PMAs on parts for CFM-56 engines. The greatest opponents of PMA have jumped on the bandwagon.
The PMA industry is facing a level of acceptance that we could only dream about 10 years ago when the association was founded. There’s no such thing as something for nothing. But, people are recognizing that you can get a great deal on PMA parts.
