LINCOLN, NEB. — Duncan Aviation is pleased to announce a new partnership with Extant Aerospace to provide critical support for legacy aircraft components. Extant Aerospace recently acquired an older JET/L3 product line and is dedicated to ensuring the continued availability and functionality of these essential parts for legacy aircraft.

This product line includes critical components for EPS (emergency power supplies), emergency lighting, stick pusher, static inverter, static converter, and LRUs (line-replaceable units) on various aircraft, including popular models from Embraer, Gulfstream, Beechcraft, Sikorsky, and others.

Understanding the significant role these parts play in operational safety and compliance, Extant Aerospace enlisted Duncan Aviation’s Parts & Rotables Sales team to lead sales and distribution efforts.

“We sought a partnership with Duncan Aviation to support the established customer base for the JET/L3 stick pusher and emergency power supply products we acquired in 2022,” said Madison Blake, Extant Aerospace Business Unit Manager. “This came with the need to serve dozens of new customers across hundreds of unique part numbers. Duncan Aviation has provided valuable insight into customer needs and solutions to ensure the best service to the end users. The partnership has been successful in serving the market and providing more support to meet customer needs all over the world.”

Recognizing that many operators rely on these parts to keep their aging aircraft operational, Duncan Aviation is committed to stocking parts in its Lincoln, Nebraska, facility, making them readily available on DuncanAviationParts.com, via email at PartSales@DuncanAviation.com, by or by phone at +1 402.475.4125 and 800.228.1836.

Chris Gress, PRS Business Development Manager at Duncan Aviation, emphasized the importance of having a ready stock of these components to meet customer needs efficiently. "These units are manufactured on demand, with lead times ranging from six to twelve months," he explains. "We are proactively conducting research and forecasting demand to maintain an inventory level that will reduce the waiting time for operators.”

Think Ahead. Order Ahead.

To better serve domestic and international customers, Duncan Aviation encourages operators to communicate their anticipated needs and annual usage for these parts.

This collaborative approach allows Duncan Aviation to order ahead, reducing lead times and ensuring that customers have access to OEM (original equipment manufacturer) parts when they are needed most.

In an industry where downtime and operational efficiency are critical, Duncan Aviation’s partnership with Extant Aerospace demonstrates a forward-thinking approach to sustaining essential product support for years.
