Southwest Airlines is beginning to run up against reliability, parts obsolescence and supply challenges with the attitude display indicator (ADI) on the 737 Classic fleet, says Kent Horton, Southwest’s director of engineering.
Despite reliability and spare parts issues, Southwest does not have any plans—at least for now—to replace the electro-mechanical cockpits on the 130 Boeing 737-300s and -500s it still flies. (Image: Southwest)
Analysts tracking the commercial aircraft turbine engine MRO market see a growth period for the industry from 2014 through 2023, although at a percentage rate in the low-to-mid-single digits.
According to data generated by Aviation Week analysts, the global value of the engine MRO market for 2014 is estimated at $20.3 billion, based on the in-service engine fleet of 63,000 for that year—including 3,952 new deliveries. Some aviation industry analysts project slightly higher numbers for the same period.
The proliferation of mobile devices and software that enables increasingly more complex data distribution and handling could lead to the most significant evolution in maintenance documents management since the transition from paper to electronic formats.
Boeing this fall will launch a line maintenance applications suite for mobile devices with an unidentified customer, following a year of development.
“Airlines are using more mobile technology every day, and the mobile platform is an ideal tool for mechanics to have the information when and where they need it, and to share that information with other experts or departments across the company,” says Elizabeth Holleman, a representative for Boeing Commercial Airplanes, Digital Aviation Business, in Renton, Wash.
As airlines continue to watch engine expenses, MROs are being asked by their customers to design customized approaches to service and provide material solutions. The conversation is forcing MRO vendors to search for answers outside their facilities.
As airlines continue to watch engine expenses, MROs are being asked by their customers to design customized approaches to service and provide material solutions. The conversation is forcing MRO vendors to search for answers outside their facilities.“A decade ago, the focus of engine maintenance contracts was on supporting the customer—at the time of the shop visit,” says Kristin Kenny, director of Pay Per Hour Programs for Pratt & Whitney Canada. “Now, contracts must be structured to take into account a complete understanding of the customer's operation.”
Blowing sand in the Middle East and high levels of airborne particulate matter from industrial pollution in Asia are parts of the impetus behind a new generation of thermal barrier coatings (TBC) designed to better protect engine components and withstand corrosive elements.
TBC corrosion is becoming a growing issue, specifically attributable to the build-up of calcium magnesium aluminosilicates (CMAS).

Ethiopian Airlines' fleet renewal and growth continued this week with the delivery of a new Boeing 737-800 from Seattle. Routing through Washington-Dulles and then Dublin, Ireland, the latest 737NG is Ethiopian's 16th. Since 2010, the East African carrier has taken delivery of 25 Boeing 737/777/787s as well as 13 Bombardier DHC8-Q400 regional turbo aircraft. One of the fastest-growing and most modern of African airlines, Ethiopian also has a burgeoning MRO business....More
It's easy to see why the composite machine turns heads; it sits high on a fighter-jet type landing gear, has a spaceship-like cockpit and those forward-swept wings, which beyond looking awesome, allow for a larger cabin as the main structure for the wings can be behind the seating area....More
