To be safe and remain in compliance, life limited parts are checked regularly to ensure that no items remain in service beyond their expiration date. Depending on the type of maintenance program, items like oxygen generators are checked while the aircraft is in for the equivalent of a C-Check, or about every 18-24 months. The overhead passenger service units (PSUs) are opened so dates on the oxygen generators can be visually checked. At that time, mechanics read the date of manufacture, which may involve loosening a bracket, rotating the generator so the data placard is visible, reading the date and then reinstalling the bracket. Life vests are managed in a similar manner, with lots of time spent crawling around the floor looking under a seat cushion to check a date. A calculation to determine the remaining service life is done to make sure the item will not expire before the next check, allowing for an appropriate safety margin. If it is determined that the part will still be serviceable until the next scheduled visit date, the mechanic tightens everything up and moves on to the next location. For comparison, there can be approximately 60 oxygen generators on a typical B737 to 200 or more on a B777 — depending on theLeading the Way with manufacturer and must be replaced after a certain configuration and there can be hundreds of life vests amount of time — whether in service or sitting on a that require inspection. It can be very time-consuming shelf. These are not generally tracked as well as Repairable to check each part, taking from a few hours to a whole inventory and require time consuming inspections to shift or more.Inventory Management confirm serviceability.

The portable RFID scanners connect via Wi-Fi at hangar and line station locations. Mechanic training for the wireless handheld scanner application was easy and only took about 30 minutes on the aircraft. Training for the server side application is slightly more involved. That’s where the LOPA (LayOut of Passenger Accommodations — essentially the floor plan of the airplane) is created for each fleet configuration and populated with the desired emergency equipment. The process is assisted by a GUI (Graphic User Interface) design tool and some basic configuration menu selections — such as, Economy is 3x3 seating starting at row number 11 and continuing for 28 rows; and immediately you’ve generated a picture of the Economy section seating. Adding lavatories, galleys, closets, exit rows, extra aisles, etc. is easy. The locations are click-and-drag positioned and can be named according to the appropriate nomenclature. The layout is easily created and looks like the actual aircraft so all equipment will be located where it is expected on each aircraft. The design tool accommodates single aisle, double aisle and double decker, also allowing for custom named classes and extra sections. The server software also holds the software configuration options, reference part data and reporting functions. Once the LOPA is configured in the software, each location (seat, PSU, closet, etc.) is populated with a life vest, oxygen generator, etc. until there is a complete map (and database) of every piece of equipment for each aircraft.

20 | WHITE PAPER: ADS | AIRCRAFT IT MRO | FEBRUARY-MARCH 2013 W hy do we talk about technical records scanning? Anybody can scan paperwork today because everybody has a big photocopier that can print, fax, copy, scan… in fact, everything but make the coffee! However, all too often the user, whether MRO or airline, ends up with a lot of PDF files holding black and white images. Even with rigorous naming of and architecture for file storage, it will often take as long to dig into PDF files as into paperwork, in which case it might be quicker to refer back to the paper work in the first place. Introducing the expense of an OCR (optical character recognition) engine such as ADOBE ACROBAT Pro, will at least assist in using the windows search engine, if enabled on your computer, or the search engine from ACROBAT, but only on clearly printed characters. Using ACROBAT INDEX/SEARCH engine will make it possible to have all files combined into one, thus, say, having a 20Gb PDF file for one year of records on an A320. Some MRO software allows users to link individual PDF or TIF files to task cards or a parts history. However, this can be time consuming, most often the time of engineers whose job should be more about monitoring maintenance operations than scanning and linking files to corresponding electronic records in the MRO system. This is still prevalent in many airlines and sometimes when, in these times of cost reduction, the cost of sitting an engineer behind a scanner becomes prohibitive, the linking of scanned records behind electronic records is simply abandoned. So, when a lease ends and the time for repossession arrives, large numbers of engineers have to revert to the records and make copies of certain documents to suit the lessor’s redelivery conditions. Added to which, most lessors have their own way of requiring the records. These days, we hear increasingly about eSignatures for maintenance operations and electronic record keeping. Without doubt, this is the future but there are still some issues. Firstly, aircraft compliantTechnical records – making them work with full eMaintenance, such as the A350 or B787, are new and currently represent less than 1% of the global fleet: against that, many aircraft between five to 40 years old remain in service. These old birds still have their delivery documents and maintenance records only in paper format or sometimes even on microfilms. Secondly, asJulien Albrecht, General Manager, Aircraft Data Systems considers how to transform paper into useful information? no global standards have yet been established and accepted for aircraft electronic records, local aviation authorities will not certify an aircraft with only scanned copies of records. Some airlines“…aircraft compliant with full eMaintenance, such as the A350 or B787, are new and currently represent less than 1% of the global simply do not look at aircraft that don’t have full paperwork traceability. fleet: against that, many aircraft between five to 40 years old remain in service.” Aircraft Maintenance Records, it seems, will still be around for at least another 30 years.

22 | WHITE PAPER: ADS | AIRCRAFT IT MRO | FEBRUARY-MARCH 2013 Indexing is the key Even after having recognized the printed content of the pages there is still a good chance that users will miss the records they are looking for. Since 2005, we have found that 95% of searches are related to non- routine information which is handwritten in most cases and hand written information still cannot be properly read with software: that is one of the reasons why it is called ‘Dirty Finger Prints’ (DFP). But what this means is that 95% of searches will concentrate around the 5% of information that is not recognized even with seven OCR engines… and there is still a chance that the OCR will have messed-up in recognizing the part and serial numbers. To finally achieve a 99% search capability rate, every single page needs to be presented to operators for a quality check and eventual correction. This also allows operators to input handwritten information into indexes so that the final user can search even on ‘dirty finger prints’. In most cases, users should find a cartouche on every page that indicates information about the detailed maintenance operation. We have added what we called Optical Zonal Recognition or OZR which allows users to define layouts of task cards for specific MROs or Airlines and apply a layout reading capability, indicating which area should be stored in which index. Like, but not limited to, Registration, MPD (maintenance planning document) task reference, Work Pack reference, related parts, AD / SB (airworthiness directive / service bulletin), Modifications EO (engineering order). This allows all the records to be Even so, the OCR software can still confuse a ‘0’ (nought/zero) and an ‘O’ (capital letter ‘O’), scanned by work packs with only one reference – PO (purchase order) an ‘l’ (lower case letter ‘l’) and a ‘1’ (number one) or ‘S’ (capital letter ‘S’) and ‘5’ (number or WO (work order) reference. The software does the rest. All indexing is five)… For common words this is corrected using the standard dictionaries but, for part and done virtually and, as the records are the responsibility of the operators, serial numbers it can quickly become such a huge headache that engineers will give up on nobody should alter their content. Once the work packs have been scanning and using scanned copies and revert to paperwork. scanned, they can be stored to a remote safe location exactly as they were These days, the cost of computer storage is so cheap, except for Cloud based systems, that produced by the operator or the MRO. It becomes pointless to revert to the it would be easy to dramatically reduce document quality in order to save a relatively small paperwork again. amount of money. But, reducing the quality of scanning reduces the value of scanning.

We use information as possible. USB sticks to fill that gap with software designed to run on any platform (except IOS Mac). Documents have to be presented as what they are, with indexes and title related to the maintenance operation. Who cares about the file number or its location? But who does not care about having access to all airworthiness directives and service bulletins related to a specific landing gear? Indexing could be achieved by putting printed barcodes on A4 pages in front of specific sets of paperwork or by scanning them into specifically named files, but this would be more time consuming and would ultimately represent a prohibitive increase in the cost of the solution. “Indexing could be achieved by putting printed barcodes on A4 pages in front of specific sets of paperwork or by scanning them into specifically named files, but this would be more time consuming and would ultimately represent a prohibitive increase in the cost of the solution.”

26 | CASE STUDY: AIR WORKS | AIRCRAFT IT MRO | FEBRUARY-MARCH 2013 “Today we are standing at a crossroad wherein, on the one hand there is a serious threat to legacy but also, on the other hand, a tremendous opportunity to create a simple, beautiful (and low cost) but practical IT which can be a potent business differentiator and confer huge competitive advantage.” I T is a wonderful thing: I mean… none of us would be doing the jobs we do in quite the way we do them if it wasn’t for IT. In fact, a lot of what makes the modern world go round and, importantly for us, helps airlines to fly around and over it can be credited to IT with its power to marshal information and help get things done. But, like any strong force, IT can be a power for good or for bad and needs to be handled carefully, not only to leverage the best value from its capabilities but also because, like any power, mishandled it can bite. That’s a lot of responsibility for those involved. So, it matters what goes on inside the head of a Chief Information Officer, Chief Technology Officer, Chief Architect, Enterprise Architect or anyone who is trying to take IT strategy decisions in today’s world of volatility (business and political) and technology disruption (especially with the two ‘Cs’ – Consumerisation and Cloud – getting into the enterprise zone). What should a CIO think about? Today we are standing at a crossroad wherein, on the one hand there is a serious threat to legacy but also, on the other hand, a tremendous opportunity to create a simple, beautiful (and low cost) but practical IT which can be a potent business differentiator and confer huge competitive advantage. It’s all down to managing information, as Bill Gates put it: “Virtually everything Ravinder Pal Singh, Global Chief Information and Technology Officer at Air Works, identifies the IT dilemmas in business today is an undifferentiated commodity, except how a company manages its information. How and opportunities that faces airlines today and suggests how a business might use them you manage information determines whether you win or lose.”
