FAA Approved S-1B2 Arctic Tern (S/N 2001 and subsequent) Airp lane Flight Manual , IETDC Doc. No. A2B-8500, Revision 1, date d July 11, 2007, or later FAA approved revision. A-754, Rev. 10 Page 7 of 13 Data Pertinent to all Models: Datum Wing leading edge at side of fuselage Leveling means Level front and rear spars of stabilizer at fuselage. Production basis Model S-1B1 : None. Prior to original certification of each aircraft manufactured subsequent to February 23, 1945, a CAA or FAA representative must perform a detailed inspection for workmanship, materials, and conformity with the approved technical data, and a check of the flight characteristics. Model S-1B2 (block 1000) : None. Prior to original certification of each aircraft, an FAA representative must perform a detailed inspection for workmanship, materi als, and conformity with the approved technical data, and a check of the flight characteristics. Model S-1B2 (block 2000) : None. Before original airworth iness certification of each aircraft, an FAA representative must perform a detailed inspection for workmans hip, materials, and conformity with the approved technical data, and a check of the flight characteristics. In the even of an application for a standard airworth iness certificate or, if an applicant intends to produce a new aircraft under 14 CFR § 21.183(d), a nd the applicant is manufacturing, building, or assembling to another person’s type certifi cate, the applicant must provide evidence of permission from the type certificate holder. Conduct of such activity without written evidence of permission may be a violation of 49 U.S.C. § 44704(a)(3). Optional Equipment: A plus (+) or minus (-) sign preceding th e weight of an optional item indicates the net weight change when that item is installed. Approval fo r the installation of all items of equipment listed herein has been obtained by the aircraft manufacturer except those items preceded by an asterisk (*). This symbol denotes that approval has b een obtained by someone other than the aircraft manufacturer. An item so marked may not have been manufactured under a CAA or FAA monitored or approved quality control system and, therefore, its conformity with CAA or FAA approved technical data must be determined if the item is not identified by a CAA Form ACA- 186, FAA Form 186, FAA Form 8130-3, FAA PM A, or other evidence of CAA or FAA conformity inspection or production approval.
