7. Main Seat Spring Check
Check the spring condition and test the operation of the spring.
If the spring shows excessive corrosion or has started to compress then it should be changed out.
The Frog-3 Spring can be susceptible to yield over time. The Frog-3 spring is deemed fit for purpose until it yields
beyond 5% in length. This can be verified by measuring the free length of the spring or measuring the deflection of
the seat base in-situ. The following checks are recommended to identify whether the spring is fit for purpose:
1. In-situ check The Frog-3 Sliding Sleeve Cross Bolt Runner should rest against the slotted Sliding Sleeve,
with a pre-compression force of approximately 60kg. If a space exists between the slot edge
and the Cross Bolt Runner greater then 13mm, the Spring should be replaced.
2. Free Length check Free Length of a new Frog-3 Spring is 825mm (+/-16mm). If the Free Length is less than
785mm the Spring should be replaced.
8. Sliding Sleeve and Alignment Cross Bolt
Inspect the alignment cross bolt in-situ. Check for any deformation of the bolt or excessive wear on the nylon
bushings. Replace with new cross bolt and bushings as required.
– Note: This is a special high yield strength bolt.
9. Landing Feet - Examine the feet to ensure that they are in good condition and that they are properly secured to the
capsule. Do not go underneath an active lift. Notes:
iii. Measure height of foot and replace if under 150 mm in height
iv. Small (20 mm in length) cuts are acceptable but feet should be replaced when the internal foam
becomes visible
10. Seat Base Assembly - Visually inspect for any wear or damage and ensure that all bolts’ and other fasteners are
fully secure.
11. Frame and Buoyancy - Visually inspect for any damage and ensure that all bolts and fasteners are tight and fully
secure.
12. Seat Harness Security (Critical Part) - Visually inspect the seat harness attachment points and the harness webbing
for any signs of wear, fraying or damage. Check that attachment points are secure.
13. Seat Harnesses (sit-in) -C heck all seat harness buckles to ensure each is functioning correctly. (Inspector to sit in
each seat and check fastening and unfastening of each harness).
14 Load Test (see Section 6.8 ) – On critical parts replacement, a load test (see Table 3 in Section 6.3 ) must be
conducted by an independent test house company, nationally recognised and in accordance with ILO 152.
15. Inspection Data Plate - Update the inspection data plate after completion of approved examination/inspection.
16 Post Load Test Visual Inspection (See Section 6.7 ) – If load test done, c onduct and report a post load test visual
inspection.
Storage
17. Storage of FROG - Check the storage cover is in good condition and not showing any signs of UV or wind
degradation.
