Those surplus military Bombardier Model U-1A aircraft, identified by civil and military serial numbers in Bombardier Report QA/DHC-3/G13, are eligible for a U.S. Standard Airworthiness Certificate without requiring a Canadian Certificate of Airworthiness for Export when all of the following conditions have been satisfied: (a) Aircraft records must indicate, or a determination must be made, that the aircraft has been subjected to FAA initial screening inspection. The screening inspection record must show that the aircraft has a reasonable potential for standard certification. (Those aircraft dispositioned as havi ng no reasonable potential for standard certification are not certifiable. These aircraft are sold by U.S. Department of Defense only for the purpose of "Recovery of Parts or Reduction to Scrap".) (b) The aircraft must be converted to Bombardier Model DHC-3 in accordance with Bombardier Modification SOO- 3028, Issue 6, and Bombardier Service Bulletin 3/21, Original Issue. (c) The applicant shows and the FAA finds that the aircraft conforms to the type design and is in a condition for safe operation. (d) A satisfactory "100 hour" type inspection has been accomplished and recorded. (e) Any deviations to the type design must be appropriately approved by an FAA Supplemental Type Certificate or other methods acceptable to the FAA. Upon satisfying all the foregoing conditions, and when all other pertinent U.S. regulatory requirements have been met, a U.S. Standard Airworthiness Certificate may be issued. (Certification basis is FAR 21.183(c) since these are import aircraft.) Technical data needed for conversion purposes are available to the applicant through Bombardier of Canada Limited. Inquiries for this data should be submitted to The Product Support Department, Bombardier of Canada, Limited, Downsview, Ontario, Canada. -END-
