The following components have a calculated fatigue or wear life. They
should be replaced at the following intervals:
Lower Lift strut Bolts 500
Upper Lift strut bolts 1000
Leading and Trailing edge to fuselage
attachment bolts 1000
Wing fold spar attachment pins 500

9.10 Fabric
9.10.1 The Skyranger can be fitted with either Dacron or Xlam coverings. It
should be noted that Dacron degrades more rapidly than Xlam when
exposed to UV light, and therefore requires more care to ensure a
long service life.
9.10.2 Prolonged outside uncovered storage is not recommended.
9.10.3 Covering fabric and its stitching can be tested with the BMAA
approved ‘Bettsometer’. This will be done annually during its UK
Permit to Fly renewal inspection. In addition it should also be done
after each 100 hours of flight or after each 20 days of accumulated
outside storage (such as resulting from touring use) – whichever
accumulates the sooner.
9.10.4 The minimum Bettsometer test values for the Skyranger are:
Dacron 1000g
Xlam 1360g
All stitching 1360g
9.11 Damage to fabric
9.11.1 Small tears in the fabric up to 30mm long, or abraded holes up to
15mm diameter, that are more than 50mm from a seam line, or can
