Among the results of Aircraft Technical Publishers (ATP) acquiring CaseBank Technologies and its fault detection and troubleshooting software are new tools using that technology. CaseBank’s ChronicX solution, for example, enables aircraft operators to set up automatic detection of recurring defects, allowing the operator to tackle these issues before they cause bigger problems. Now ATP (Booth Z131) has released a new function for ChronicX, custom alerting that sends notifications via email to warn about problems before the aircraft needs to be grounded.
ChronicX is designed for fleet operators and is currently used by many airlines. Now, it is also under evaluation by large business aircraft fleet operators. “We’ve already started conversations with [business aviation providers],” said Steve Lightstone, ATP’s v-p of the ChronicX business. “It’s for any organization where reliability is important.”
ATP has long been known for its distribution of regulatory and maintenance publications and for its ATP Maintenance tracking software, but the acquisition of CaseBank gave the company new solutions to offer its customers. “It’s much more than just regulatory and technical publications,” he said. “A lot of customers don’t know that.” CaseBank’s SpotLight troubleshooting software is used by many business jet OEMs, including Bombardier and Gulfstream, and engine manufacturer Pratt & Whitney.
The problem that ChronicX solves is a result of the way discrepancy information is typically gathered. Most operators use some form of logbook that pilots and technicians use to make notes about squawks. There are two problems with that, Lightstone explained, that make the notes somewhat useless in identifying trends such as recurring defects that can’t be replicated on the ground.
The description field in logbooks, whether paper or electronic, is usually freeform. The pilot or technician can write whatever they want, using any word or description, and these can vary widely for a problem that might be similar or even identical. The other issue is that there are huge inconsistencies in the coding of ATA chapters. So the numbers used for that purpose are essentially useless, again, because there is no consistent application of chapter and subchapter numbers to identify a particular problem. “On top of that there’s the notion of identifying recurring problems,” Lightstone said. “This creates a pain in reliability organizations [fleet operators].”
Some operators rely on crude spreadsheets to try to manage logbook data, and this doesn’t make finding recurring defects any easier, especially with inconsistent verbiage in the description field.
What ChronicX does is use algorithms and a dictionary of aircraft maintenance synonyms and user-defined terms to make sure that similar defects can be detected and grouped together. Instead of having to pore over pages and pages of spreadsheets looking for items that might refer to the same kind of defect or a recurring problem affecting a single component, ChronicX can do this automatically. “It means spending more time fixing rather than finding,” he said. This also eliminates the need to code logbook entries with ATA chapters, because that data doesn’t add any value.
Fifteen months ago, ATP/CaseBank had 500 aircraft using ChronicX, and that has since climbed to 2,500. “We expect 5,000 by the end of the year,” said Lightstone.
The development of custom alerting for ChronicX was a result of customer requests. While mining the descriptive text is by itself useful, they wanted a way to be notified when the data-mining found a special situation, he explained. Users can define the search criteria and set rules for notifications. But ChronicX’s algorithms also know when to issue an alert even if the particular similar wording isn’t found. “It’s smarter,” he said. “You can define an alert for a nosewheel shimmy, and it knows the synonyms to kick off an alert—like [the term] ‘nose wheel vibration’—so the user doesn’t have to input the exact synonyms.”
As more operators move to electronic logbooks, tools like ChronicX will be able to dig through data faster. Typically, operators with paper logbooks rely on data entry personnel to re-enter logbook entries into a computer, which could introduce errors and delays in mining that data. “We’re starting to see the impact of electronic logbooks,” Lightstone said. “Several of our customers are implementing them.” Even with re-entry of data, however, ChronicX can help overcome errors by detecting synonyms, even when words are misspelled. “There are algorithms that help with that,” he said.
A next step for the CaseBank products is to integrate ChronicX with ATP’s Maintenance software, according to Victor Sanchez, ATP v-p of product management. Text messaging of custom alerting is on the ATP roadmap, he said. Custom alerting is available to ChronicX customers at no additional charge.
