R&D Activities EMAS Longevity Factors EMAS Design Generation (early designs compared to new generation methods) Materials used in the system (material, protective coatings, seals, wraps, moisture barriers) Expected Environmental Effects Over Time (precip., temperature changes, UV, jet blast, humidity, etc.) Severe Environmental Damage (rare weather events associated with hurricanes, flooding, etc.) EMAS locations to large bodies of water has increased probability Periodic Inspection & Maintenance (replacing damages or changes to original condition & upkeep)

R&D Activities EMAS Inspection & Maintenance (I&M) The Task Select 6 U.S airports with EMAS +8 yrs or older Some airports have both older and newer EMAS generations Older Gen (501): Cement board JBR top, caulk joints, core material sealed directly to surface New Gen (502): Fiberglass polymer JBR top, bottom plastic tray, seam seal tape Gather I&M programs from EMAS manufacturer & airport Gather information on who, when, where, and how I&M are done, repairs, materials, costs associated, & significant findings.

R&D Activities EMAS Inspection & Maintenance (I&M) Goals Information to make decisions on EMAS Longevity Find issues or concerns with I&M (airport operator, manufacturer, or FAA Region/ADO) Common issues & costs associated with maintaining EMAS Information to provide airport education on EMAS Provide information/criteria to FAA Cert Inspectors to know what to identify during annual inspections Possible updates to FAA Advisory Circular on EMAS Guidance information to provide airports on replacement

R&D Activities EMAS Inspection & Maintenance (I&M) Early Findings… Report due April 30, 2016 Early Findings… I&M manuals are well written and comprehensive Cover every aspect for inspection, maintenance, and repair Procedures to accomplish are not always reasonable or practical in an airport environment. Airport Operators make significant efforts to follow I&M to extent practical Efforts are labor intensive, expensive, and unending Limited access to beds, environmental restraints to repair, persistent jet blast damage (501)

R&D Activities Early Findings…continued Older Gen (501): wear and tear is most severe in wet/moisture climates and high exposure to jet blast (setback distance) Expectation that efforts & costs will increase over time Newer Gen (502): Stark difference to compare conditions! Improvements to design has significantly reduced I&M, however it is still very labor intensive. Regardless of condition (501 or 502), EMAS has been validated by the manufacturer & expected to perform as designed.

Future Research through FY18 EMAS Longevity – NO EASY SOLUTION Critical Factor – Can the EMAS arrest an aircraft to its design? Field Strength Testing FAA Testing? 3rd Party Testing? Manufacturer Certification? Core Material Moisture Content? Function of I&M? Inspection & Maintenance and Damage Over Time? Findings from I&M Report? Cost of Materials & Labor Hrs? NEW Materials & EMAS Design Reviews / CRDA Provide Technical Information to update EMAS Advisory Circular Continued Discussion with FAA Airport Engineering (AAS-100)
