The hull premium aspect of your total annual premium will be anywhere from 60 to 70 percent, which can vary based on what policy you have. Most of your annual premium will be in your hull insurance. You always want to ensure the Hull at whatever the current market value of the aircraft is. By making sure your aircraft is properly valued and not over-insured or underinsured, you will be ensuring that the top underwriting interest is received every single year. Every underwriting company will evaluate the value of your aircraft compared to current Vref, Blue Book, Controller, or varied other sources. If the value of your aircraft is way off compared to market you may want to provide further explanation as to why (new avionics/TBO, interior/engine mods, low/high time).
