3 common issues for product adhesion

What are the benefits of PMA Sealants?

Why use aerospace PMA parts?

NSL Aerospace pioneered the use of PMA sealants in the aviation industry. We were first-to-market with our line of NSL PMA Sealants back in 2008. We are big believers in the benefits of Parts Manufacturer Approval (PMA) parts for so many reasons. Part of our mission is to help our customers achieve better business results from their use. To do that, we are writing blog posts and pages to clearly explain their use.

Many professionals have heard of PMA sealants but aren't sure about their specifics or how to adopt them. We've written about common hurdles to PMA implementation. Today, we would like to look at their benefits and why so many people are on "team PMA parts" for their aircraft.

Benefit #1: Cost Savings

If you're looking to stretch your budget and grow your profit margins, PMA parts are a great place to start. By incorporating PMA parts into their aviation maintenance program, our customers generally see a 30-50% savings. Those are measurable results that can boost your bottom line, too!

Benefit# 2: Shorter Lead Times

We often hear stories of frustration from new customers as they relate the exceedingly long lead times they had with OEM parts. As you might guess, these delays muck up the work of multiple departments and processes. By contrast, PMA manufacturers like NSL Aerospace are laser-focused on product delivery speed. These are two of our biggest strengths: quick turnaround and just-in-time deliveries. That means you can skip the inventory management, long lead times, and delayed orders by ordering exactly the amount of PMA sealant you need, right when you need it. That's a big deal!

Benefit #3: Increased Supply Chain Stability

Many PMA sealants offer faster cure times than their OEM equivalents. Time saved is money saved, so this is important to note.

Are PMA Products Safe?

It's a well-known fact that in the industry, vendor management is key to your aviation and aerospace operations. With PMA parts, you have an OEM alternative. This creates a choice for you and your department. As a result, you are empowered to control costs, be less susceptible to supply chain interruptions and reduce any risks caused by a vendor's delivery habits.

Benefit #4: Improved Product Performance

Something we want to emphasize is that we are committed to the highest quality work. To assure that, we maintain AS 9100D and ISO 9001:2015 certifications, as well as Nadcap accreditation. As part of that, our Houston-area facilities are regularly inspected by industry experts to certify compliance. Going above and beyond, we employ an on-site lab that tests samples of products. These double quality checks truly set us apart as a distributor with unswerving commitment to product standards and safety.

Additionally, as PMA holders, we have multiple responsibilities to uphold, per the FAA. We even go above and beyond those by conducting a second round of testing for a sample of each batch in our facilities near Houston, Texas.

For well over a decade, we've worked with customers in 45+ countries to help them adopt PMA sealants. We know getting started can seem difficult. To help, we've created and increased our Resources page over the years. It's a great place to start as you build familiarity and confidence in these products. You'll be glad you did when you realize their multiple benefits.


We hope this page has increased your confidence in PMA products generally, and NSL Aerospace specifically. If you have additional questions, please check out our Resources page or reach out to us.
