15. 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)

16. 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.

18. 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

19. 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)

20. 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.
