Aeronautical Accessories offers replacement Windows for the Bell 407 High Visibility Crew Door Kit. The High Visibility Crew Door Kit for Bell 407 helicopters is a modification to the existing door that incorporates an expanded and bulged window that provides 30 percent more viewing area. This kit is ideal for law enforcement and any other applications where enhanced visibility and crew shoulder room is a plus. The kit can be used in conjunction with the Bulged Skylight Kit. Contact your salesperson about loaner doors. Important Note: Please inspect your doors being sent in for high visibility modification prior to shipment to Aeronautical Accessories to ensure they are airworthy. If the door is found unairworthy, any repair costs will be over and above the high visibility door modification cost. Receipt of an unairworthy door will also significantly impact your quoted lead time.
