Thank you, Rell. Good morning, everyone. As Geoff mentioned, both revenues and new orders in the second quarter were up from the first quarter. This is consistent with our expectation for steady improvement over the course of this year.
Orders in the quarter were $4.2 million and backlog as of March 31, 2018, was $3.8 million. We're undertaking a concerted effort to strengthen our Autothrottle franchise. Once the STCs are obtained for the King Air series, we will have a range of Autothrottles in the market that address a fleet, the estimate totals 5,000 aircraft.
As we increase the potential installed base of our Autothrottle by developing additional STCs, product recognition from industry publications, complemented with our increased emphasis on sales and marketing, is resulting in growing interest in the Autothrottle product line.
We expect to broaden up from this space with products for other Turboprop aircraft that leverage the technology behind the design of our standalone Autothrottle.
To that extent, we are in discussion with a number of potential candidates as part of the process of hiring an experienced Autothrottle product manager to be the focal point for program management, marketing and sales of this high-potential product line.
We also have been approached by a major engine manufacturer, with an interest to team and jointly monitor the Autothrottle with their engines.
Our discussions with various aircraft OEMs, with regards to offering our utility management system, continues to gain momentum. Pilatus PC-24 is now in commercial production and is providing a steady pace of ongoing orders as we are the sole source supplier of the utility management system on that platform.
International opportunities continue to be a focus of our 7 marketing efforts. In fact, in the second quarter, 40% of our revenue was from international business.
In China, air cargo growth continues, and many operators are looking to convert older Boeing 737, 757 and 767 aircraft into cargo planes.
This is an area where we have great product and retrofit expertise. To capitalize on the local knowledge, we are partnering with MROs in that region to develop opportunities.
[ And ] MROs remain an important facet in our overall sales and marketing strategy. In addition to the local knowledge they can impart, they offer a cost-effective means to globally expand our distribution network. We plan to continue with growth of our MRO network within the U.S. and international.
The number of aircraft in which we have installed equipment continues to increase. As a result, we are experiencing a steady growth in customer service revenues.
In summary, we are focused on creating value for shareholders through our strategy to develop the industry's best price -- performance products and to grow the sales by expanding on marketing.
Let me turn the call back to Geoff for some closing remarks.
