Freefall lifeboats fall under SOLAS III and the LSA Code; class/flag typically require the 5-yearly on-load release gear overhaul and load test, annual thorough examination, and records of weekly/monthly drills. Any modification to the release gear needs manufacturer and class approval and re-certification.
Estimated lifetime: Lifeboats are commonly given a design/service life in the order of 20-25 years by the manufacturer, subject to condition-based extension after survey - hull and release-gear condition, not running hours, govern actual serviceability.
