Inspector Detail
▸
Common issues
- Skid/ramp release mechanism seizing from corrosion or paint build-up
- Freefall release hook misalignment or failure to reset cleanly after a dry test
- GFK hull gelcoat cracking, particularly at the bow area from repeated free-fall impact
- Engine starting failure after prolonged standby
- Harness/seatbelt degradation from UV exposure and wear
- Painter line and secondary retrieval line chafe
- Ramp/skid lubrication breakdown causing an uneven or delayed launch
Inspection checklist
- Visual hull inspection, including the bow impact area, for cracks or delamination
- Freefall release hook dry function test
- 5-year on-load release gear overhaul/load test
- Skid and ramp condition and lubrication check
- Harness and seat condition check for all occupant positions
- Engine start and cooling system test
- Battery and electrical system check
- Painter and secondary means of launching inspection
- Hydrostatic release unit service-date check, if fitted
- Cradle securing and lashings condition check
Service intervals
| On-load release gear overhaul | 5 years, class-witnessed per SOLAS/LSA Code |
| Full davit-free-fall system thorough examination | 12 months |
| Engine servicing | per running hours or annually |
| Skid/ramp lubrication | per maker's schedule, commonly every 6-12 months or before each drill |
Typical wear limits
| Hook pin/bushing wear | renew per the maker's tolerance stated in the O&M manual |
| Harness webbing | renew on visible UV degradation, cuts, or fraying, or once the maker's rated service life is reached - confirm against the harness label/manual |
Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.
Critical spares
- Freefall release hook assembly components (name only - confirm exact part with maker)
- Harness sets
- Engine starter battery
- Ramp/skid lubricant (maker-specified type)
- Hydrostatic release unit, if fitted
Safety
- Free-fall launch carries inherent occupant-injury risk from impact deceleration
- Accidental operation of the on-load release hook during maintenance
- Fall-from-height risk during boarding and drills
- Engine exhaust build-up during confined start tests
Class survey
Freefall lifeboats are under LSA Continuous Survey: annual thorough examination plus the 5-yearly on-load release gear overhaul; class pays particular attention to release-hook maintenance history given the industry's known incident record with freefall systems.
