Thank you, Chris, and thank you, everyone for joining us today. I'll begin by providing an update of the quarter with -- and some market color, after which I'll turn the call over to Joe Bellino to review our financial results in detail.
Ducommun, as we anticipated, made strides in a number of fronts during the first quarter. Our growth in the commercial aerospace sector continued, and consolidated net sales increased to $184 million, up 83% from last year's first quarter, including the impact of LaBarge acquisition. We saw solid expansion and improvement within our AeroStructures business unit driving the company's total adjusted EBITDA to 10.3% of revenue as we focused on improving asset utilization and posted better results from our new business development initiatives.
While we're pleased with our progress, we know we have a lot more work to do and expect to continue to post improvements throughout the year. Ducommun LaBarge Technologies, or DLT, had solid performance in the aerospace and defense markets, but we did see a drop in the revenue due to lower sales in the industrial and medical markets as we outlined last quarter. That said, DLT's margins and working capital performance was encouraging.
Our use of cash improved $20 million year-over-year, dropping to $5 million this quarter as compared to $25 million a year ago. This reflects solid working capital management and improved operating efficiencies. Prudent cash flow of management will continue as a priority for Ducommun as we plan to reduce the company's debt level later on this year.
Our backlog at quarter end grew to a record $647 million, illustrating strength in our commercial aerospace and military end markets, along with improving medical orders offsetting some near-term weaknesses in our natural resources and industrial markets. I'll provide more color here in a moment.
While we're not where we want to be, overall, we're pleased with the progress we made this quarter in terms of margins, cash flow and backlog, reflecting our focus on these areas.
Now let me talk a little bit about the marketplace dynamics. The commercial aerospace segment is still exhibiting strength as demand for large commercial jets fueled build rate increases as expected. Passenger miles showed no sign of letting up, and we're very optimistic about our programs with both Boeing and Airbus. With demand for new aircraft rising, we're also seeing increased quoting activity from many of our customers while we are being asked to provide support for the higher build rates. We anticipate that we will see expanded backlog based on the commercial aerospace sector in the next several quarters assuming market conditions remain as they are today.
We're experiencing slightly lower demand in regional jet market, but this is being offset by a higher demand in the large aircraft general aviation markets, as well as with commercial helicopters. The Carson Helicopter business remains robust, and we anticipate that this will stay strong throughout the year.
The defense market is changing. The threat of sequestration adds another level of complexity, which we believe will require across-the-board spending cuts to meet our anticipated budget targets if sequestration is imposed. However, I think the proposed budget from Secretary Panetta gives us a clearer picture of where the DoD is heading. U.S. Defense spending will focus on creating a leaner and more nimble infrastructure with fewer Armed Forces but with higher technology applications and spending on upgrades.
The Army will take the brunt of the DoD proposed budget cuts by reducing personnel and drastically reducing spending on land vehicles, neither of which will affect Ducommun. We expect missile defense spending to remain flat and military helicopter development to continue to be funded but with the funds spread over various platforms. The Joint Strike Fighter build rates will stay at lower production levels until full development is complete, opening funding for the retrofit markets and upgrades across other platforms.
We expect the airborne intelligence, surveillance and reconnaissance or the ISR market to remain strong, so while there are definitely changes coming, we're positioning Ducommun to be flexible enough to successfully adapt to these changes while looking for opportunities to support the new low-cost environment.
We are also supporting the OEMs in the form of foreign military sales, an area which will help offset the DoD spending declines. Many companies say that they're well positioned, but when you look at Ducommun, we are very well diversified in the DoD market. We have a strong presence in helicopters, missile defense and fixed wings. We have an increasing presence in the ISR drone market and have several promising programs -- program opportunities there as well. We're also very well positioned to support the growing requirements for foreign military sales particularly with our significant support in the airborne radar installations.
We're much more diversified today than we have been in the past with regard to DoD support. However, as we discussed last quarter, in our non-aerospace markets, we continue to see softness in the industrial area resulting in lower-than-anticipated sales. The natural resources markets have also been slow due to lower natural gas pricing but has been partially offset by an uptick in the oil exploration markets.
We expect the industrial market to remain sluggish for Ducommun through 2012 as one of our major customers, Owens-Illinois, is rebalancing their capital requirements. The medical and commercial electronics markets, however, are seeing some pickup and we expect them to strengthen throughout the year. These markets are much -- move much more rapidly than the A&D sector and offer opportunities to expand our customer base.
We feel confident that margins will expand going forward. And as we continue to improve performance in our development programs, our focus will be continue to strengthen our balance sheet and cash flow with plans to reduce our existing debt during the second half of 2012. Now I'd like to turn the call over to Joe Bellino for a more detailed financial review. Joe?
