Technical inspections

Full inspection is recommended every 24 months, if not advised otherwise by the

inspecting person due to current paraglider condition.

Paragliders in commercial use (training and tandem flights) should be undergoing

Full Inspection every 12 months (excluding first 24-month period after purchase).

Technical inspection is carried out by the manufacturer or authorised person.

MANUAL FOR PARAGLIDER CHECKS

Check-intervals

All paragliders used in flight must be checked at least every 24 months. For

paragliders used by paragliding schools the period is 12 months.

Personnel authorised to carry out checks

Training course by manufacturer is the basis for permission to carry out paraglider

checks.

Identification of glider

An identity sticker with details of certification and serial number is attached to the

glider.

Components of the check

Porosity

The porosity should be checked with a porosity meter (JDC). Compare the resultant

data with the producer's manual.

Porosity measures should be taken on at least three points of both the top and

bottom surface. The first point should be placed 20-30 cm from leading edge in the

middle of canopy. Second and third points are placed left and right from first measure

point at 25% of the span. One additional measurement should be made on the top

surface of the wing tip.

The identified time should be higher than 30 second (JDC). In the event of the result

being less than 30 seconds, the result of the check is a fail.

Overall strength check

The check of canopy strength should be made with a Bettsometer (B.M.A.A

approved Patent No. GB 2270768 Clive Betts Sales). On the top and bottom

surfaces make small holes with a needle at the Aline attachment points. The exact

verification should be made in accordance with the Bettsometer user manual.

Line strength check

Line strengths should be as specified in accordance with the certification

requirements. One main line should be taken from each array and have its strength

checked with a tension-meter.

Required strengths should be higher than:

• A + B main lines x measured value > 8 x maximum take-off weight and higher

then 800 kg for the A + B arrays.

• C + D mean lines x measured value > 6 x maximum take-off weight and higher

then 600 kg for the A + B arrays.

Replacements for damaged lines must be with new original lines. Line lengths are

taken from the lines data page.

Full line length measurement

Lines should be separated and each line measured under a tension of 5 kg.

Measurement is made from the line karabiner to the canopy`s surface in according to

the method of certification. Measurement of brake lines is made from the knot on

swivel to upper loop of galery line. The lenght of bunching line is not included. Rib

numbering begins in the middle of canopy and leads to the wing tip.

Measured full lengths should be documented in the inspection record and are

compared with certified full line lengths protocol. Lengths should not differ by more

than 10 mm. The opposite sides should be checked for symmetry.

Canopy line-attachment points check

Attachment points should be checked for damage and stretching. Defects, loops and

flares should be repaired.

Canopy fabric check

Ribs, diagonal ribs, top and bottom surface should be checked. Any damage to

sewing or tears to the fabric, which could influence flying characteristics must be

repaired.

Lines

All lines should be checked for tears, breaks any damage to the sheath or signs of

wear. Special attention should be paid to the sewing of the line loops. Damaged lines

must be replaced.

The results should be documented in the inspection record.

Connector check

All line carabineers, trimmers (if used), speed systems and pulleys should be

inspected for visible damage. Open or improperly secured connectors should be

secured in accordance with the producers recommendations.

Risers

Both risers should be checked for tears, signs of wear or any damage and measured

with a pull of 5 daN strength. Measured data should be documented in the inspection

record. The difference must not be higher then 5 mm when compared to specified

lengths.

Final check

The glider sticker and check sticker must be inspected for readability and

correctness. The check must be documented with date, signature and stamp on the

canopy and in the user manual.

CONSTRUCTION OF THE CANOPY

LINE PLAN – ELAN 2

LENGTH OF LINE – ELAN 2 - 22

Mentioned line lengths are marked on stretched lines that are pulled under 5 kg. The real length measured from one loop to other loop differs in according

to type of the line, its diameter and type of processing method (sewing or splicing). When replacing a line always compare the symmetry with opposite side.

LENGTH OF LINE – ELAN 2 - 24

Mentioned line lengths are marked on stretched lines that are pulled under 5 kg. The real length measured from one loop to other loop differs in according

to type of the line, its diameter and type of processing method (sewing or splicing). When replacing a line always compare the symmetry with opposite side.

LENGTH OF LINE – ELAN 2 - 26

Mentioned line lengths are marked on stretched lines that are pulled under 5 kg. The real length measured from one loop to other loop differs in according

to type of the line, its diameter and type of processing method (sewing or splicing). When replacing a line always compare the symmetry with opposite side.

LENGTH OF LINE – ELAN 2 - 28

Mentioned line lengths are marked on stretched lines that are pulled under 5 kg. The real length measured from one loop to other loop differs in according

to type of the line, its diameter and type of processing method (sewing or splicing). When replacing a line always compare the symmetry with opposite side.
