  • Definitions

Airlock: On a canopy, a valve which permits air flow more easily in one direction, and restricts airflow in the opposite direction. In most case, airlocks are installed in the nose of the canopy to permit air to enter during deployment and flight, and restrict air from flowing out the nose to ensure better pressurization in turbulent air.

Angle of

Attack: The angle formed between the flight path and the chord line. The Greek letter alpha (α) is used to denote the angle of attack. See Figure 3.

Trim: The angle formed between the horizontal reference line and the trim line. The Greek letter theta (θ) is used to denote the angle of trim. Used instead of the somewhat analogous aircraft term “angle of incidence.” See Figure 1b.

Area, Airfoil Section: The finished cross sectional area of a given rib (airfoil) section. When ribs are not identical, the specific rib must be identified. Used for calculations of pack volume and internal volume of canopy.

Planform: The product of the average chord times the average span of the canopy.

Projected: The area of an inflated canopy as viewed from above, perpendicular to the chord line at the centerline of the parachute. Due to canopy curvature and cell inflation bulging the projected area is always smaller than the planform area.

Aspect Ratio: Span2/Area, which for a rectangular planform reduces to Span/Chord.

Page 2 of 8

Attachment Point: A loop of tape, webbing, or the functional equivalent, for attaching something to the surface of the canopy.

Pilot Chute. An attachment point for the pilot chute or pilot chute bridle, including any reinforcement to reduce the effects of abrasion, and also including any additional rib- or canopyreinforcing tapes intended to distribute the load from the pilot chute to the canopy.

Suspension Line. An attachment point for a suspension line or control line. Some canopies use extensions of rib-reinforcing or flare-reinforcing load tapes to form line attachment points. See also Flare, Suspension Line Attachment.

Cell: The chamber formed by upper and lower surfaces and two adjacent loadbearing ribs.

Channel, Drawstring: A fabric or tape channel that encloses a drawstring, most often found on main canopy sliders.

Pilot Chute Reefing: A channel that runs through the center of the canopy, from upper surface to the lower surface, to allow the pilot chute bridle to connect to the slider.

Chord: The distance from the farthest forward point to the farthest aft point on an airfoil section. If the canopy airfoil sections are not identical, an average chord may be specified. Airfoil dimensions are assumed to be finished dimensions unless otherwise specified. See also Span, and Line (Design), Chord.

Construction, Chordwise: A construction method in which upper and lower surfaces are assembled from panels which run from front to rear (chordwise) and are joined to the ribs and each other using a variety of sewn seams. The most common type of ram-air parachute construction.

Spanwise: A construction method in which the upper and lower surfaces are assembled from panels that run from side to side (spanwise) across the full width of the canopy. Personnel parachutes usually require three or four panels each for the upper and lower surfaces.

Crossports: Holes cut in the rib sections to balance the air pressure between adjacent chambers. Drawstring, Slider: A length of tape or line which may be pulled to collapse or remove a slider after deployment.

Flare, Suspension Line Attachment: An extension of a load bearing rib used on some canopies to distribute suspension line loads along the lower rib seams. A suspension line attachment flare may be integral with the rib or may be sewn to it.

Line (Design), Chord: A line drawn through the farthest forward point and the farthest aft point on an airfoil section. See Figure 3.

Reference, Horizontal: A line drawn at a right angle to the Vertical Reference Line. Usage is equivalent to the practice of using the aircraft longitudinal axis as an aircraft reference line. See Figure 3.

Reference, Vertical: A line drawn through the links and the quarter chord point.

Page 3 of 8

Trim: A line drawn through the farthest forward and farthest aft line attachment points (excluding control line attachment points). See Figure 1b.

Line (Rigging), Cascade: A line attached with one end at the canopy and the other end to an intermediate point of an adjacent line. Contrast with Continuous.

Continuous: A line attached with one end at the canopy and the other end at the riser of connector link. Contrast with Cascade.

Control: A line fastened to the trailing edge of the canopy, used to steer and modulate the forward speed and descent rate of the parachute. Also known as steering or brake line.

Flare: A control line intended primarily for flaring the canopy for landing, but which may also for steering. Also known as Secondary control lines, in which case the remaining control lines are known as Primary control lines.

Brake-Toggle: When a control line is constructed in sections, that portion of the line between the toggle and the deployment set eye (“cat-eye”).

Lower: When a control line is constructed in sections, that portion of the line between the deployment set eye and the upper portion.

Upper: When a control line is constructed in sections, that portion of the line between the canopy and where it converges with other lines attached to the canopy.

Identification System for:

Suspension lines: lettered “A,” “B,” “C,” . . . from front to rear along each load-bearing seam. Numbered from outboard to inboard (outboard lines numbered “1”; see Figure 2a ) or inboard to outboard (lines on center load-bearing seams numbered “1”; see Figure 2b).

Control lines: numbered by rib seam, including non-load-bearing ribs, from outboard to inboard. See Figures 2a and 2b.

Suspension: One of the lines that carries the load from the canopy surface to the risers. Control lines are usually not considered suspension lines.

Pilot Chute Controlled Reefing (PCR): A parachute reefing system that uses the drag of the pilot chute to modulate the opening rate of the canopy.

Planform: The overall shape of the wing as viewed from above, perpendicular to the chord line. Quarter Chord Point: a point on the chord line one quarter of the distance from the nose to the tail of an airfoil.

Removable Deployment System (RDS): A slider variation that permits the slider to be removed and stowed separately after deployment. “Full RDS” is a further variation that also permits the pilot chute, bridle, and deployment bag to be removed and stowed after deployment.

Rib: A section of fabric installed between the upper and lower surfaces of a canopy. Used to establish the airfoil shaped of the canopy. Rib numbering systems (for example, from outboard to inboard, or from inboard to outboard) vary from manufacturer to manufacturer.

Page 4 of 8

Rib, crossbrace: A rib or partial rib installed at an angle other than a 90° angle to the upper and lower surfaces of a canopy.

Rib, loadbearing: A rib to which suspension lines are attached, installed at a 90° angle to the upper and lower surfaces of a canopy.

Rib, non-loadbearing: A rib without attached suspension lines, installed at a 90° angle to the upper and lower surfaces of a canopy.

Rib, stabilizer: A stabilizer-end rib assembly with line attachments along the lower edge. Rigging, Crown: A suspension line length pattern in which all “A” lines are the same length across the span of the canopy, all “B” lines are the same length across the span of the canopy, and similarly all “C” and “D” lines, etc.

Flat: A suspension line length pattern in which the lines in the center of the canopy are shorter than the lines farther outboard. In flight, the center part of the airfoil is flatter and creates more vertical lift than a crown-rigged canopy, which generates lift along the radius of the spanwise arc. Setting, Deployment: The position of the trailing edge when the control lines are pulled down to their deployment position.

Full-Flight: The position of the trailing edge when the control lines are fully extended.

Slider: A parachute reefing device usually consisting of a rectangular section of canopy cloth reinforced on the edges with lightweight webbing or tape, and with a large grommet or D-ring installed at each corner. Sliders may have fabric removed from the rectangular section or may have fabric edge extensions installed to change opening characteristics. Slider variations include:

Domed, with a planform similar to a flat rectangular slider, but with fabric pleated along the edges.

Split, capable of being disassembled into halves after deployment .

Spider, made of two lengths of webbing sewn in an “X,” and usually used with pilot chute controlled reefing. See Pilot Chute Controlled Reefing (PCR).

Removable. See Removable Deployment System.

Slider Bumper: A small device, typically made from vinyl/silicon tubing, Type-4 tape, or Type-12 webbing, installed at the lower end of the suspension lines to prevent damage to the slider grommets caused by the slider contacting the connector links.

Slider Stop: A small piece of rigid material (metal, plastic, phenolic, etc.) normally covered in tape or light webbing, installed on the lower edge of a stabilizer panels to prevent a slider grommet from riding up over the stabilizer material and damaging the stabilizers or the slider.

Slider Stop Chafing Pad: A tape or fabric reinforcement installed on a stabilizer at a slider stop to reduce wear from abrasion.

Soft link: A connector link constructed primarily of fabric or tape.

Span: The distance from one side of a canopy to the opposite side. Measurements taken at various distances aft of the nose will yield different results, Measurements taken across the upper surface will typically be longer than those taken across the lower. An average span, or separate leading and trailing edge dimensions, may be specified. Airfoil dimensions are assumed to be finished dimensions unless otherwise specified. See also Chord.

Page 5 of 8

Stabilizer: A fabric panel installed at the end of a canopy, intended primarily to reduce wingtip vortices (much as an end plate on an aircraft wing), and to provide some directional stability. Some stabilizer designs are ram-air pressurized for additional rigidity.

Tapes, Reinforcement: A tape installed in the canopy to provide additional strength or dimensional stability. Tapes are identified by location.

Cross Tapes: A reinforcing tape that runs spanwise on the upper or lower surface to distribute loads through the canopy. With chordwise construction, a cross tape typically runs from a line attachment point to laterally adjacent line attachment point, although some may run from a suspension line attachment point diagonally to a control line attachment point. With spanwise construction, a cross tape may be rolled into a seam joining spanwise panels.

Leading Edge Tape: A tape applied to or rolled into the leading edge of a upper or lower panel. May be continuous across the span of the canopy.

Line Attachment Reinforcement Tape: A tape sewn chordwise into a seam at a line attachment point.

Load Tape: A tape applied to a rib section and used to distribute the load from a line attachment to the canopy. When applied in a “V” may also be known as a “V-tape.” In some canopies, load tapes may extend through the lower seam to become line attachment points.

Rib Leading Edge Tape: A tape applied to or rolled into the leading edge of a rib section. Trailing Edge Tape: A tape applied to or rolled into the trailing edge seam. Usually continuous across the span of the canopy.

Toggle, Control: A grip attached to the end of the control line to allow the user an adequate handhold on the line. Most commonly consists of a tape/webbing loop or a hard plastic dowel. Typically supplied as part of the container assembly.

Trim: The arrangement of differential line lengths to produce a desired trim angle and anhedral. See also Angle of Trim. See Figures 1a and 1b.

Vent, Lower Surface: An opening in the lower surface to provide an alternate path for pressurization during deployment (“inflation vent”) or depressurization during flight (“accuracy vent”).

  • Parachute Canopy Fabric Pull Test Non-Destructive Method

Disclaimer: Parachute canopy manufacturers may have pull test requirements that differ in methods, procedures, and loads applied. Test procedures specified by the canopy manufacturer takes precedence over the test procedures described in this document. The person performing the pull tests must determine if the canopy manufacturer has a specific method of pull testing their canopy fabric.

Background: The purpose of this test method is to provide a simple, standardized, non-destructive method of verifying the strength of parachute canopy fabric. This test method may be used when no other procedure is specified by the manufacturer. Although this test is intended to be non-destructive, caution should be exercised as this test could damage the fabric, if the fabric is not positioned correctly or is not secured tightly. It may also affect the fabric permeability.

This method is designed to replace the old "Riggers' Thumb Test", first devised in response to the "canopy acid-mesh" discovery in the mid-1980's. It is now the accepted method for all parachutes requiring canopy fabric strength tests. Reasons for testing may include:

Manufacturer’s Service Bulletins (SBs), Airworthiness Directives (AD’s), aging material, chemical contamination, UV exposure or discoloration of a suspicious origin, such as grease. Tools required and possible sources are as follows:

Sharpie Pen- black 1 ea. Calibrated Spring Scale, 50 lb. (23 kg.) minimum capacity This scale should be calibrated at least once a year to an accuracy of +/- 3 lbs. It should be identified with a serial number and written verification of calibration must be kept on file. An adhesive label (or similar) should be affixed to the scale showing the date calibrated and the date next calibration is due. If the scale is damaged in any manner, such as dropping, it must be pulled from service and tagged as unserviceable until its recalibration.

Test Procedures: The following procedures do not take precedence over a manufacturer’s test procedures for their products. Before testing make sure you have the manufacturer’s most current test procedures.

A minimum of 2 areas should be tested on a canopy, but not less than 2 pull tests on each separate color (1 in the warp direction and 1 in the fill direction). When testing look for areas of contamination and/or discoloration. If possible remain approximately 6 inches (150mm) from any seam.

Proceed as follows:

NOTE: Steps 1 and 2 apply to cases involving acid-mesh pull testing.

1.

Locate the mesh vents in the canopy and determine the fabric areas which are in contact with the mesh when the canopy is packed. These areas are shown as the diagonally shaded lines in typical tri-vent canopies (see FIGURE 2).

2.

Perform one 40 lb. (18 kg.) pull test on each panel of material that comes in contact with the mesh when the canopy is packed. Alternate tests from the warp to fill direction on the panels. This could be as few as four tests or as many as twelve tests on some bias constructed canopies.

CAUTION: Never attach fabric clamps or perform pull tests on the mesh covered areas of any canopy. Extensive damage will result.

NOTE: Steps 3 through 6 apply to all pull tests (not just acid-mesh).

3.

The area to be tested must be visibly marked for future reference. Refer to FIGURE 3 for examples of how to mark the parachute to be tested.

4.

After the marking ink has dried, attach the locking fabric clamps to the ripstop fabric as shown in FIGURE 4. The distance between the clamps should be 3 inches (76.2mm) plus or minus ¼ Page 2 of 8

PIA-TS-108.1 inch (6.35mm) and the clamps must be aligned so that the ripstop pattern is parallel (not on bias) to the edge of the jaws. Lock the clamps VERY SECURELY. This will prevent slippage and possible damage to the fabric.

NOTE: If the area to be tested is too small to allow 3 inches (76.2mm) plus or minus ¼ inch (6.35mm) between the jaws of the fabric clamps (such as the apex area of a round canopy), the distance between the jaws may be reduced to 2 inches (50.8mm) plus or minus ¼ inch (6.35mm).

5.

Secure one clamp to the packing table or other object which will allow a sufficient load to be applied without movement of the fabric clamp. Attach the spring scale hook to the other fabric clamp and apply the load very smoothly and steadily. Hold the load for 3 seconds.

6.

Record test results on the tested areas in contrasting ink as shown in FIGURE 5. Information should include the following:

The amount of loading pulled to in pounds or kilograms

The date tested

The word PASS or FAIL

The name and certificate number of the individual performing the test.

After completing the tests record the information in your rigger logbook and on the packing data card.

Per Table 3, there shall be not less than 6 drops, with an individual and/or dummy in each harness weighing not less than the maximum operating weight2. The average rate of descent shall not exceed 24 ft/s (7.3 m/s) and the total velocity shall not exceed 36 ft/s (11.0 m/s) in an unaltered post deployment configuration, corrected to standard day sea level altitude conditions.

The rate of descent measurement shall be taken over a minimum interval of 100 ft (30.5 m).

These tests may be combined with other tests in this section.

4.3.9.1 RATE OF DESCENT TESTS (METHOD 2):

The rate of descent corrected to standard day sea level altitude conditions shall not exceed 5 ft/sec (1.5m/sec) at touchdown with appropriate control manipulations and the average rate of descent shall not exceed 24 ft/sec (7.3 m/s) in the unaltered post deployment configuration over a minimum interval of 100 ft (30.5m). These tests may be combined with other tests in this section.

NOTE: If the total velocity exceeds 36 ft/sec at maximum certified weight, the container or harness (if integral to the container) must be marked in an area readily visible to the user: “For experienced parachutists only. The owner‟s manual contains experience requirements.”

4.3.10 STABILITY TESTS:

Per Table 3, there shall be not less than 6 drops, at the minimum operating weight. The oscillations shall not exceed 15 from the vertical, in an unaltered post-deployment configuration.

These tests may be combined with other tests in this section.

4.3.11 LIVE TESTS:

Per Table 3, there shall be a minimum of 4 live tests with an individual weighing not more than the maximum operating weight in each harness. Two drops shall include a freefall of not more than 3 seconds and 2 drops shall include a freefall of at least 20 seconds. These tests may be conducted in conjunction with functional and/or rate of descent tests when practical. The user(s) must suffer no significant discomfort from the opening shock and must be able to disengage himself (themselves) unaided from the harness after landing. For this test the standard harness may be altered to permit attachment of a certified reserve parachute assembly (less harness) provided that such alteration does not interfere with the normal operation of the parachute assembly being tested. Reserve parachute assemblies shall be tested with the main compartment(s) full and empty, with a minimum of two tests each.

NOTE: Live tests for Dual Harness Reserve Parachute Assemblies may be tested with the parachutist in command and a dummy payload in the passenger harness.

5.

COMPONENT QUALIFICATIONS:

Any single component, assembly of components, group of components or group of assemblies may be certified. Table 4 lists the appropriate test paragraphs for each of the major components.

Any components not listed in Table 4 shall be tested according to all applicable sections of this document based on the components function.

2 A person‟s or individual‟s body weight may be increased to equal the maximum operating weight by using a weight belt or similar device.

  • APPENDIX 1. MINIMUM PERFORMANCE STANDARD FOR PERSONNEL
  • PARACHUTE ASSEMBLIES AND COMPONENTS

This appendix prescribes the MPS for a personnel parachute assembly and component. The applicable standard is PIA TS-135 Revision 1.4 issued April 22, 2010 Performance Standards for Personnel Parachute Assemblies and Components, as modified for this TSO:

1.

Page 2, replace Para, 2.1.i. to read as follows:

“Cognizant Agency” - The Federal Aviation Administration (FAA) or civil aviation authorities recognized in bilateral agreements by the FAA,

2.

Page 5, Para. 4.1.2. delete: “generally”.

Stitching should not ravel when broken. “Generally” reduces the requirement for stitch choice, and adversely impacts the current standard.

3.

Page 5, Para. 4.1.3.delete: “Ref: Table 2”.

Table 2 is not relevant to this requirement. Testing of a packed assy will show if the main parachute will interfere with the proper function of the reserve parachute.

4.

Page 9, Para. 4.3.7. in first sentence delete: “a weight not more than”.

The worst case is the maximum operating weight.

5.

Page 11, disregard paragraph 4.3.9.1., Rate of Descent Tests (Method 2).

We omitted the Method (2) testing, for not providing an equivalent level of safety to current standard. This method is directed at high performance and experience parachutists in sport and skydiving activities. Novice or less experienced parachutists in emergency conditions due to incapacitation, panic, etc., may not be able to safely deploy and land.

We have to consider the safety of all jumpers, not just the highly skilled, highly experienced. It is argued that the risks the experienced jumpers are exposing themselves to, are mitigated by their skill and experience.

To allow the increased velocity may improve the safety of highly skilled, highly experienced jumpers, but it erodes the safety for the beginner, incapacitated, panicked, or a jumper who has gotten himself into a treacherous landing area.

  • TSO-C23f 09/21/2012
  • Page 6

We do not agree that a canopy manufacturer can demonstrate that a jumper can safely land with an appropriate control manipulation while performing a flare before touchdown. This approach relies on jumper’s experience to meet the MOPS that parachutes have been certified to. This approach does not provide an equivalent level of safety.

Page 14, Table 1, under Marking Data Requirements, replace:

Statement of Authorization under TS0-C-23e and/or (J) TSO-C-23e if applicable.

With

Statement of Authorization. Under TSO-C23f and/or ETSO-C23f if applicable.
