Services may include onsite examination of the aircraft, photography, review of related records, depositions, literature searches, research, analysis, consultation time, preparation for deposition and trial testimony, oral or written reports, preparation of exhibits and demonstrative evidence, all travel time (billed portal to portal), deposition and trial testimony, waiting time for deposition and trial testimony, watching or assisting during the testimony of others, and other related tasks requested by client. Any time related to the case or project which is beyond the scope of an initial telephone interview of the consultant may be considered billable time at our published rates. All fees for out-of-office work are billed portal-to-portal.


A retainer is required prior to commencing any litigation support.  At a minimum, a desktop appraisal fee per helicopter plus an additional fee of $800.00 per helicopter, for 2 hours of document review, research and analysis will be used to determine the retainer fee.  The retainer represents the minimum fees to be paid for review of a case, and it will be applied to invoices for completed work and may be adjusted by the appraiser upon initial review of the case.   If the retainer is in excess of the final bill, the difference will be refunded to the client. If additional services are required, you will be invoiced accordingly.
