there is no specification for height. A table is only desirable  if the parachute rigger is going to pack round parachutes.  With the predominance of square reserve parachutes in the  skydiving community, some parachute riggers specialize in  packing only square reserves. A table can be used for packing  this type of parachute, but the manufacturer may specify  any smooth, clean surface of a size that accommodates the  canopy. In this case, a clean, carpeted floor does the job and  a table may not be necessary. According to 14 CFR part 65,  subsection 65.127(b), the parachute rigger needs suitable  housing that is adequately heated, lighted, and ventilated for  drying and airing parachutes. This is subject to interpretation  by the parachute rigger and the Administrator since the  standards fluctuate based on location and time of year. A parachute rigger must have enough tools and equipment  to pack and maintain the types of parachutes for which he or  she is rated to service. This may include only the basic tools  of a packing fid, temporary pin, and pull-up cord if this is all  that the manufacturer says is necessary to pack its product.  However, there is a broad selection of tools necessary for a  well-equipped parachute rigger to possess. These are covered  in detail in Chapter 6, Hand Tools, Sewing Machines, and  the Parachute Loft. A number of performance standards are defined in 14 CFR  part 65, section 65.129 to guide the parachute rigger’s  performance of the duties that fall under the certificate. The  parachute rigger may not: It is also possible for candidates who pass the test but receive  a marginal score to retake the test with the anticipation of  getting a higher score. In this case, the candidate must wait  a minimum of 30 days from the date the last test was taken  to retake a passed test. Prior to retesting, the individual must  give his or her current airman test report to the proctor. The  most recent test taken reflects the official score. The last item in this list is one that has been abused by  many Master Parachute Riggers over the years. The Master  Parachute Rigger must have Administrator or manufacturer  approval, in writing, to be in compliance with this regulation. Aside from the necessary tools, 14 CFR part 65, subsection  65.129(f) states that parachute riggers may exercise the  privileges of the certificate only if they understand the current  manufacturer’s instructions for the operation involved. This  means that the rigger must possess a copy of the instructions  or have access to them during the operation. If they do not  have a copy, but the owner of the parachute provides them,  then the parachute rigger may pack or maintain the parachute. Issuance of a Parachute Rigger Certificate is just the first  step toward becoming a professional parachute rigger. As  the un-certificated apprentice gains experience packing, he  or she should also begin to acquire an inventory of tools and  manuals necessary to exercise the privileges of a certificate.  In compliance with 14 CFR part 65, section 65.127, there are  several items required. One of these requirements is a smooth  tabletop that is at least 3 feet wide by 40 feet long. Note that  Parachute riggers have a broad range of responsibilities  that include ensuring that proper facilities and equipment  are available to him or her, adhering to certain performance  standards, record keeping, and use of their seal. The following  describes the responsibilities of a certificated parachute rigger. 1-5 U.S. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration Airman Knowledge Test Report NAME:  APPLICANT ID: EXAM:  Parachute Rigger Senior (RIG) EXAM ID: EXAM DATE:  04/20/2004 EXAM SITE: SCORE:  96 GRADE: PASS TAKE: 1 Below are subject matter knowledge codes in which questions were answered  incorrectly.
