5、s Hazards. FOD hazards onairports are considered to be comparable to thoseassociated with birds and winter operations. Coststo one major airline average $15,000 per aircraft,which represents an industry cost of over $60million per year. This is the equivalent of one newmedium-sized transport categor
6、y jet. Tests andexperience have shown that foreign objects onairport pavements can be readily ingested byaircraft engines, resulting in engine failure. Debriscan also become lodged in mechanisms, affectingthe operation of landing gear, flaps, etc. Thesehazards can be reduced, however, by theestablis
7、hment of an active FOD preventionprogram. While snow and ice and wildlife aresignificant causes of FOD, these concerns areaddressed by other ACs (see par. 4, RelatedReading Material) and are beyond the scope of thisdocument.b. Typical Foreign Objects. Typicalforeign objects include the following: ai
8、rcraft andengine fasteners (nuts, bolts, washers, safety wire,etc.); mechanics tools; flight line metal (nails,personnel badges, pens, pencils, etc.); stones andsand; paving materials; pieces of wood; plasticand/or polyethylene materials; paper products; andice formations in operational areas.6. PRE
9、VENTIVE MEASURES. The followinginformation is intended to help in establishingairport programs for preventing foreign objectdamage. It is particularly applicable to airportowners and operators, air carrier station managers,and general aviation operators. Individuals inthese positions are expected to
10、 alert ramp crews,maintenance technicians, and aircraft servicingpersonnel to the safety hazards created by debris.Procedures to eliminate FOD must address twofundamental requirements: (a) the avoidance ofdebris and (b) the removal of debris fromairport pavements. Consider the potential of allairsid
11、e activities in the cause of FOD. Forexample, using ordinary surveyors flags instead ofspecially designed markers to mark edge lights forsnow removal may easily precipitate a FODsituation. Advisory Circular 150/5200-30, AirportWinter Safety and Operations, provides details onrecommended edge light m
12、arkers.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-AC 150/5380-5B 7/5/962a. Identifying Causes. The causes andprincipal contributing factors to FOD at a specificairport location must be determined before aneffective local prevention program can b
13、edeveloped. For airport operations, airportconstruction, and aircraft maintenance, one shouldaddress potential problems with FOD as a result ofthese activities and undertake preventive measuresfor each.b. Establishment of a FOD AwarenessProgram. Each individual with access to anairport operations ar
14、ea should understand his/herrole in prevention of FOD. A formal orientationprogram familiarizing new employees with securityand communications procedures, vehicleoperations, etc. should include FOD awarenesstraining. Address in this training the hazardsassociated with debris and tactics for FODpreve
15、ntion. A joint program with airport tenants,including the establishment of a FOD preventioncommittee, will help to broaden and sustainawareness of the FOD problem.(c) Establishment of a MaintenanceProgram. Each activity on the airport should havea FOD prevention program tailored to thatparticular ac
16、tivity. Some suggestions are asfollows:(1) Aircraft Maintenance. Account forand dispose of nuts, bolts, washers, safety wire, etc.Account for hand tools used in repair jobs. Aids inthe control of these items include checklists,shadow boards, and cut out tool tray liners.(2) Air Cargo. In an air carg
17、o area,there is a high potential for blowing debris such asplastic cargo wrappers. Establish procedures tocontain such debris, possibly by installing fencingwhere appropriate. Of course, FOD trapped bysuch fences should be removed regularly.(3) Construction. Establish specificFOD prevention procedur
18、es for each constructionproject. These procedures should be based on theproximity of construction activities to operationalareas but in general should stress containment andregular cleanup of construction debris.(d) Inspections. Make inspections ofoperational areas at least once each day, withadditi
19、onal inspections being made in constructionareas and immediately after any aircraft or groundvehicle accident or incident or any spill of materialwhich may cause slippery conditions. AC150/5200-18 gives guidance in the performance ofairport inspections. Encouraging the participationof airport tenant
20、s in inspections will reinforce theconcept that FOD prevention is a team effort anddemonstrate the airport operators commitment to adebris-free environment.(e) Pavement Repair. Spalled or crackedpavements, while structurally sound, may requireexpedited repair to minimize the ingestion ofpavement fra
21、gments.(f) Shoulders. Areas adjacent to pavementsshould be stabilized to prevent FOD. AC150/5300-13 gives further guidance in theconstruction of stabilized shoulders.(g) Debris Removal.(1) Receptacles. Provide conspicuouslylocated, well marked FOD receptacles. Suggestedlocations include the followin
22、g: near entry pointsto the airport operations area, in hangars, inaircraft tiedown and aircraft maintenance areas,and at each aircraft gate.(2) Equipment. Consider usingspecialized brooms, magnets, and vacuum-typemachines to clean aircraft operational areas as wellas runway and taxiway safety areas.
23、 Theacquisition of power sweepers and/or vacuums foruse in FOD prevention is considered appropriate.The National Aerospace FOD Prevention, Inc.FOD Prevention Industry Guideline (Appendix 2)recommends that sweeper brushes with metalbristles or spines not be used. Plastic orcombination plastic/metal b
24、ristles may beappropriate, but the user should consult theequipment manufacturer for specificrecommendations. Regardless of the equipmentused, a thorough check of the pavement should beconducted at the conclusion of the sweepingprocedure.(3) Pavement Joints. Give specialattention to the cleaning of
25、cracks and pavementjoints as tests have shown that these are the mainsources of foreign objects which are ingested.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-7/5/96 AC 150/5380-5B3(and 4)7.

30、TRY GUIDELINEThe following is a reprint of the National Aerospace FOD Prevention, Inc. FOD Prevention Industry Guideline.Although the appearance has been altered for the purpose of this AC, the content of the guideline is the same.FOREWORDThe purpose of this document is to establish a guideline for
31、the prevention of foreign object damage (FOD) toaerospace products being designed, developed, manufactured, assembled, operated, repaired, modified,refurbished and maintained.Most FOD can be attributed to poor housekeeping, facilities deterioration, improper maintenance or carelessassembly and opera
32、tions practices. An effective FOD prevention program identifies potential problems,corrects negative factors, provides awareness, effective employee training, and uses industry “lessons learned”for continued improvement.The objective of the FOD Prevention Industry Guideline is the preservation of pr
33、ivate and national assets andto reduce the hazards to life that are inherent in aerospace activities.This document is intended to be used as a baseline FOD prevention policy/procedure. Users are encouraged toapply the contents of this guideline to suit their particular product or company.INTRODUCTIO
34、NNational Aerospace FOD Prevention, Inc. is a nonprofit, educational undertaking. The purpose of theorganization is to provide the aerospace industry with information about the prevention of foreign objectdamage to aircraft and aerospace vehicles. The intent is to make the aerospace industry aware o
35、f the need toeliminate foreign debris, and to provide information about current proven practices and technologicaladvancements that prevent FOD. Additionally, board members work with all interested companies,associations, and government agencies to accomplish this purpose.This guidance is developed
36、by the Board of Directors. The Board was established in l985 to oversee theactivities of the National Aerospace FOB Prevention Conference and represents members from aerospacecompanies, suppliers, associations, and government agencies. This guidance is designed to provide assistance,advancement, and
37、 share awareness with the aerospace industry. Valuable “lessons learned” have been sharedso that the industry can become more effective in their individual FOD prevention programs.It is anticipated that as the industry accepts and implements these recommendations, Quality and productintegrity will i
38、mprove, thereby increasing productivity and reducing avoidable cost. The Board recognizes eachprogram must be individually based on company philosophies, contract requirements, and policies. Thisguidelines will be helpful toward the goal of permanent and continuous improvement in promotion of flight
